TKISS REQUIRED TO GO GREEN WITH ICE

hose of us of a certain age may recall from our childhoods Kermit the Frog lamenting from his lily pad that “It’s not easy being green.” Today, that could easily be revised to “It’s not easy going green.”

There are a multitude of options of varying complexity and cost available to deliver more ecofriendly machines. Yet, I’ll throw back to another memorable phrase which dates to the 1960s: “Keep It Simple, Stupid”, or more often referred to as the KISS principle. In essence, the concept is that designs and/or systems should be as simple as possible in order to guarantee the greatest levels of user acceptance.

When it comes to powering machines, the “simple” solution to going green is to improve the performance of existing internal combustion engines, thus reducing fuel burn and emissions output. This could be as minor a step as changing out fluids and filters to eke out incremental improvements, or as involved as extensive changes in materials and components to deliver quantifiable results. Regardless of the approach, the core engine technology remains the same, making it easier in the eyes of the end user to accept.

Approval of “drop-in” fuels such as HVO, renewable diesel, biodiesel, propane and others is another relatively simple solution that can significantly lower emissions output – if approved by the manufacturer and if supplies are readily available and at the right price.

Pairing ICEs with today’s advanced hydraulic systems – some of which may be offered in packaged subsystems for easier integration – presents a further means to maintain the familiar power source while delivering gains in overall machine efficiency.

Of course, the tricky bit is figuring out which solutions are right for your applications and your customers. In this case, the simplest way to find the right mix is to take advantage of the experts in their fields by collaborating with power systems and component suppliers.

Power Progress is offering the chance to do just that on October 6th, in Louisville, Ky., with the introduction of an industry exclusive networking forum. This one-of-kind event lets you pre-schedule one-on-one meetings with those experts to discuss these and other power system and component-related challenges.

And better yet, it’s followed by a party as we toast our 90th anniversary and look to the future of Power Progress! Learn more about the Power Progress Networking Forum at www.powerprogresssummit.com

The global nature of supply chains means tariffs also present challenges for U.S.-based producers. By

Chris Sleight

TWISTED TARIFF IMPACTS

April’s tariff announcements have thrown long-established trading relationships into a tailspin, as companies seek to understand the impacts and do all they can to mitigate them. While the intention is to discourage imports into the United States and give a leg up to domestic manufacturers, the reality is that supply chains for manufactured goods are global, so U.S.based producers will be facing increased input costs and will be working hard to minimize them.

The foreign content of goods will always vary from product to product and manufacturer to manufacturer, so it is not possible to make a blanket statement about

how much the tariffs will increase costs for U.S. producers. However, this is something that can be modeled.

An interesting example was given by CNH Industrial in the company's first quarter investor relations presentation, where it gave an outline example of its U.S.-made equipment. Although these would certainly be regarded as American machines, the company revealed that about 30% of the components used are sourced from suppliers outside the U.S.

Taking the figures that CNH supplied and applying the announced tariffs reveals that the cost of producing this equipment could go up 10% if the company can’t do anything to mitigate the tariffs (sourcing from less heavily taxed countries, or from within the U.S.).

(See table – the percentage component content by

country is provided by CNH, while the assumptions about tariff levels and their cost impact is from Power Progress.)

That simple exercise highlights the priority areas. In this case, the combination of volume and content sourced from China and the European Union would have the biggest impact on input prices.

A GLOBAL REALITY

But life is never that simple. Although there is no tariff on U.S.-sourced components, the suppliers of those items will almost certainly be sourcing the materials they need from around the world. At the most reductive, it absolutely will not be the case that every atom of an “American” component will have been extracted from within U.S. borders and spent its life within the supply chain inside those borders. At some

point, constituent parts of components come into the country (and perhaps cross the border many times) at which point the importer will have to pay a tariff.

As a thought exercise, assume U.S. components have the same content by origin as the finished machine (70% U.S., 30% from other countries, including EU and China), then over time the tariffs will push the cost of those components up by the same 12%. That would translate to adding a further 8% to the cost of the finished goods.

The reality of global supply chains leads on to the unintended and unfortunate outcomes in terms of the policy objective. If for example an American-made component had more than 8% Chinese content, the 145% tariff on those parts when imported would translate to a 20% increase in the cost of the component. It would therefore be compelling to source exactly the same component (with exactly the same amount of Chinese content) from Mexico and take just a 10% tariff hit.

Aggressive diesel

exhaust emission regulations

are being rolled back. Maybe that’s not such a bad thing.

By Jack Roberts

MAYBE WE NEEDED AN EMISSIONS REGS RESET ALL ALONG

The reelection of Donald Trump as President of the United States last Fall was a gut punch to climate change activists all over the world.

We’re only five months into the second Trump administration, but the President and the (justever-so-barely) Republican majority in Congress have already begun rolling back diesel exhaust emissions regulations spearheaded by the California Air Resources Board (CARB) and backed by the U.S. Environmental Protection Agency (EPA).

Say what you will about CARB, it clearly knows when it’s beat. On May 7, the agency announced that it was abandoning its controversial and unpopular Advanced Clean Fleets Rules in the face of the proactive Republican moves to roll back environment regulations – led by

ABOUT THE AUTHOR

the state of Nebraska, of all places.

MOOD STILL UPBEAT AT ACT

Given all this, I was curious what the general mood would be heading into the Advanced Clean Transportation Expo (ACT Expo) in Anaheim, Calif., in late April.

ACT Expo has emerged as one of the most important truck/transportation shows in the world over the past decade or so. It’s a show that has an unwavering focus on helping the trucking industry transition away from fossil fuels to a net-zero emissions future.

So, I was naturally curious walking into the Anaheim Convention Center as the show kicked off.

Would attendance be down? What would be the mood among exhibitors and attendees? What would be the focus of the show?

JACK ROBERTS is a Tuscaloosa, Ala.-based independent journalist and licensed commercial driver with more than 20 years’ experience covering the North American and global trucking industries.

As it happened, the show was packed. The mood was decidedly upbeat.

ACT Expo attendees were greeted by this CNG-powered Freightliner as they walked into the Anaheim Convention Center.

OEMs and suppliers had plenty of new, clean and green trucking tech to show off. And there was plenty of new technology still to talk about as well – natural gas as a truck fuel and a sense that the real-world deployment of autonomous trucks is coming soon.

There was a general consensus among industry insiders I talked to that the current emissions rollback was merely a bump in the road on the journey toward a cleaner trucking industry.

CARB’S COMBUSTION BIAS

It’s important to note that the policy makers at CARB are true believers when it comes to combatting climate change, which is why the agency has been pushing a very aggressive agenda

that would have completely phased out diesel-powered trucks by 2036. The problem was that CARB also seemed to be suffering from what some industry insiders called “combustion bias.”

As I’ve noted in the past, CARB and EPA (to a lesser extent) appeared to be ignoring excellent transitional fuels – like renewable diesel fuel and renewable natural gas – in favor of new technologies like battery-electric and hydrogen fuel cell-powered trucks.

But there are currently substantial problems with those technologies. Acquisition costs are prohibitive. Infrastructure is virtually nonexistent. And while these powertrains work well in some applications (drayage, urban delivery, short and regional haul),

PHOTO: BECKY SCHULTZ

they are nowhere near ready to being a viable option for long-haul fleets.

As I often say, the trucking industry should have been at this point in the war on climate change 20 years ago. So, I get the sense of urgency on the part of environmental regulators.

Yet, it has to be said,

Despite a concerted effort by the Trump administration to roll back diesel exhaust emissions regulations, the mood at ACT 2025 was upbeat – and even hopeful.

the policies CARB was ramrodding down the throat of the trucking industry were an incoherent, unworkable mess.

And turning a deaf ear to the legitimate concerns of the trucking industry while ignoring perfectly viable interim clean fuels like renewable diesel and

ACT EXPO

renewable natural gas was a serious strategic miscalculation on the part of CARB that turned potential allies into intractable adversaries.

WELCOME PAUSE

Now, thanks to last Fall’s election, there’s been a reset. And there’s a very real hope out there that this pause will eventually lead to more reasonable and workable climate initiatives that the trucking industry can not only live with but even embrace.

It will be interesting to see if CARB and other environmental regulators learn anything from this setback.

If nothing else, the coming four years will give OEMs and tech developers

more time to develop their zero-emissions solutions. It will also grant more time to get workable electric and hydrogen infrastructure installed and up and running. My hope is we will also see more movement toward solutions that provide cleaner and reliable fuel solutions that will allow long-haul fleets to continue to profitably move freight while cleaning up the air we breathe.

Indicates shows in which POWER PROGRESS will participate

The internal combustion engine continues to power the world. By Chad Elmore

When the editorial staff compiled the 90th anniversary edition of Power Progress (see the May issue), we spent many hours paging through back issues of this title as well as its companion publication, Global Sourcing Guide (also introduced in 1935). It’s easy to say, “things were sure different back then.” When a mine decided to get its energy from diesel gen-sets, it often replaced a building full of external combustion units (steam). When a farmer bragged about his diesel crawler tractor, that machine likely shared the barn with a team of trusted draft horses. However, after

POWER RANGE

DIESEL: 11 to 8,180 hp

GASEOUS: 95 to 5,500 hp

Caterpillar’s inline six-cylinder Cat C13D engine platform will be available in eight power ratings from 456 to 690 hp (340 to 515 kW) with up to 3,200 Nm of peak torque.

The 13 L C13D platform, which goes into production in 2026, is designed for use in a wide range of offhighway equipment. Engine mounted aftertreatment and cooling packs will be available from the factory. The C13D will meet the emissions standards of highly regulated markets, such as EU Stage V, U.S. EPA Tier 4 Final, China Nonroad Stage IV, Korea Stage V, and Japan 2014, with models available for less regulated markets.

The engine is designed to perform at altitudes of up to 12,000 ft. and in ambient temperatures as high as 140°F (60°C) and as low as minus 40°F (minus 40°C) with aids. Service intervals have been extended to 1,000 hours for oil and fuel filters.

By modularizing and eliminating components, the company said the

adjustments anticipated for future emission standards without moving customer connection points.

The Caterpillar C13D engine platform enables the use of renewable liquid fuels such as 100% HVO, up to B20 for models with aftertreatment and B100 for models without aftertreatment. Its core architecture is designed to support future development for a range of alternative fuels such as natural gas and hydrogen.

In late 2024 Caterpillar began work on a hydrogen-hybrid project by leveraging the C13D engine platform. The threeyear program is expected to develop a system for off-highway applications and demonstrate how state-of-the-art control systems and electric-hybrid components can help hydrogen-fueled engines match the power density and transient performance of diesel engines.

At Bauma 2025, the company showed a simulated test cell environment with an engine that has been run on 100% hydrogen. Caterpillar has developed multiple engines with hydrogen over the past three decades, and said it will continue to apply lessons learned through the hydrogen-hybrid project.

HD Hyundai Infracore (HDI) is set to unveil its new power generation engine, the DX15, this summer. Based on a 15.1 L, V-type and eight-cylinder configuration, the DX15 will have a power output range of 457 to 662 kWm and comply with unregulated, EPA Tier 2 and Tier 3 emission standards, making it suitable for a wide range of global markets.

Despite its compact design, the company said the DX15 will offer high performance and exceptional power density (43.8 kW/L at 60 Hz). It is also compatible with eco-friendly fuels such as HVO and GTL (gas-to-liquid) and can operate for up to 500 hours without oil replenishment.

Earlier in March, a marine engine based on the same DX15 platform was launched, delivering 551 to 870 hp of power while meeting IMO Tier 2, Tier 3, and EPA Tier 3 regulations.

HD Hyundai Infracore also launched its new DM03HP engine for power generation. This 3.4 L inline fourcylinder diesel engine complies with EU Stage V emission regulations and delivers 92 to 113 kWm, which the company said makes it a very compact engine for the 100 kVA mobile generator class.

The DM03HP is based on the proven DM03 engine platform, with optimized development leading to approximately a 25% increase in output. It supports ecofriendly fuels such as HVO and GTL, offering environmental sustainability and operational flexibility. The engine has an extended oil change interval of up to 1,000 hours.

Additionally, the DM02HP, which meets the EU Stage V emission standard and is also scheduled for release this summer, maintains the displacement of the existing DM02 engine while delivering enhanced performance.

Honda introduced two new engine design concepts at World of Concrete in 2025, including this iGX430 singlecylinder gasoline engine.

said the new iGX models will offer a standardized method for communication across ECUs. The iGX400 and iGX430 engines will have a control panel with an LED indicator that informs the user about potential problems with diagnostic trouble codes.

Honda showcased two new gasoline engines during January’s 2025 World of Concrete trade show in Las Vegas. Unveiled as design concepts, the Honda iGX400 and the Honda iGX430 are horizontal-shaft, single-cylinder engines equipped with smart fuel injection technology and an integrated electronic self-tuning regulator (STR) governor that delivers drive-by-wire remote control capability to manage engine operation.

“We have been committed to the engine business for a long time, especially with our GX lineup, which came about in 1983, and we’ve slowly evolved our products over time,” said Tyler Ricketts, assistant manager, Honda Engines, and application engineering, American Honda Motor Co. Inc. “The GX has been a really good product, and our customers are very happy with that line. Based on feedback from our customers and through our own research, a gap was revealed in our current lineup. We found that there was demand for an intermediate power range and combined with the growing need to include advanced technology, we developed the iGX400 and iGX430.”

Through the adoption of a J1939 CANbus, the company

The new iGX engines will have a higher power output and torque in a design comparable to the compact footprints of other Honda engines. While development continues, the target power output for the iGX430 is around 9.5 kW, with the iGX400 slightly less. The design compatibility minimizes changing time, making it easy for the OEM or an end-user to install the new models when older engines reach the end of their service lives. The design also allows manufacturers flexibility with current tooling and frames, said the company.

Fuel injection technology improves operating efficiencies, eliminates the engine choke, reduces fuel-associated carburetor issues, and provides easier, smoother starting after extended storage. The proven Honda Self-Tuning Regulator (STR) governor, available on a single-cylinder engine for the first time in the new models, minimizes engine rpm droop by electronically regulating the throttle opening.

The design concept behind the iGX400 and iGX430 engines is expected to offer commercial customers versatile power and greater adaptability. Potential applications for the new engines include power screeds, hydraulic power units, concrete saws, ride-on concrete trowels, vibratory rollers, generators and pressure washers.

“One of the reasons why drive-by-wire is such a benefit in this size of engine is because it allows manufacturers to place the engine in an optimal location,” said Ricketts. “Both for manufacturing and for the finished product, engineers can move the engine somewhere that fits the design but where the controls might not be as accessible.

“Hydraulic power packs, for example, are often put on large pieces of equipment, such as a truck or trailer, and by having the drive-by-wire functionality, we can put the controls inside the cab of the truck or somewhere on the trailer such as part of a control station. With this technology, we can control everything, not just the throttle. We can set up the computer for multiple ways of controlling the engine.”

Honda first gave its compact gasoline engines an integrated ECU when it introduced the iGX general purpose engine in 2005. In 2019, the company integrated ECU architecture and fuel injection technology into new models with the iGX700 and iGX800. The new iGX design concept brings the technology to smaller single-cylinder engine models.

“These concept engines make the statement that we’re here to stay,” said Ricketts. “We’re putting resources into the engine business — and we never stopped. A lot of customers rely on our engines for their livelihoods. Our GX engines mean a lot to us, and we are continually evolving, not only for regulations but to bring technology into the engine business that benefits our customers.”

PSI recently launched a new online aftermarket parts platform, replacing the first-generation online store. The company said the new website offers a modern, user-friendly interface with pictures of parts, an on-line shopping cart feature, the ability to one-click repeating stock orders and more.

PSI will merge the updated interactive parts catalog later this year with the store,

which it said will provide exploded views of engines and parts, driven by engine serial number.

During Bauma 2025 in Munich, Germany, Rehlko showed the new highpower version of the KDI 1903TCR, a next-generation diesel engine that it said was designed to “redefine performance in compact applications.” Rehlko said the new model offers a 50 kW (67 hp) output and 250 Nm (184 lb.-ft.) of torque in a compact footprint.

The engine’s design reportedly ensures maximum installation flexibility, which Rehlko said makes it ideal for a wide range of equipment in construction, agriculture and material handling applications.

The new KDI 1903TCR engine has a sophisticated aftertreatment system, featuring a diesel particulate filter (DPF) that provides efficient automatic regeneration, even at low engine speeds. The engine is engineered for operation on HVO fuel, allowing a lifecycle emissions reduction of up to 90% over standard diesel fuel without sacrificing performance or maintenance intervals. Rehlko said it has focused on serviceability by providing one-side service access and oil change intervals at 500 hours. Further customization is available, Rehlko said, with options for flywheels, oil pans and other components.

The Rehlko name, created by stirring up the letters in “Kohler,” was introduced in September 2024 to represent the newly independent business that was created from Kohler Power Systems and Kohler Engines and includes the brands

Clarke Energy, Curtis Instruments and Heila Technologies. Also shown during the German trade fair was the company’s new look. Rehlko Light Gray has replaced Kohler’s traditional bronze.

The North American debut of Scania’s Next Generation inline engine platform took place at World of Concrete in January, where the company displayed its new 13 L DC13 engine. The 13 L engine has a power range from 275 hp (202 kW) to 612 hp (450 kW) and reportedly delivers up to 11% more power and 21% more torque than the company’s current engines. The new platform also includes an 11 L engine with a power range from 275 hp (202 kW) to 500 hp (368 kW).

Torque for the DC13 is close to 2,215 lb.-ft. (3,003 Nm). While the engine displayed on the company’s stand in the Las Vegas Convention Center was designed for industrial applications, a power generation engine will also be available.

“Our mindset throughout the development of the new platform,” said Henrik Nilsson, Scania’s director of Product Management, Power Solutions, “has been to ease the transition for our customers while positively impacting fuel efficiency and product performance.”

While maintaining Scania’s modular design philosophy, some of the features of the new engine line include more precise cooling and a more rigid engine

block and single cylinder head. The new engines also get a diesel particulate filter (DPF).

“This is our most fuel-efficient engine ever, with more torque, more power and up to 50% longer base engine lifespan. A game-changer for power solutions,” said Jorg Franzke, President, Scania USA. The enhanced gas exchange system, reduced internal friction, and increased turbocharger efficiency all have a positive impact on the fuel efficiency.

For the 13 L engine, this means up to 7% improvement in fuel consumption compared to the current generation at the same power output. That translates to 4 L [about 1 gal.] of diesel saved per engine hour at full load.

World of Concrete was the North American introduction of the U.S. EPA Tier 4 final version of the company’s Next Generation engines, which were first shown at the 2022 Bauma trade show in Munich, Germany. Prior to that event, the engine was proven in Scania’s trucks for several years. For North America, series production of the New Generation engines begins in Sweden this year.

“There were global challenges that made us think about this Next Generation engine line, such as reducing CO2 emissions and driving the shift towards sustainable transport and sustainable power solutions,” said Andres Tomas Kohring, sales Top of Formmanager, Scania USA. “These new engines are our way of helping customers improve their emissions. With a 7% reduction in fuel consumption compared to our previous engines, that’s a way of being more sustainable. The new platform is also HVO capable.

“We wanted to make the transition to our next generation engines as easy as possible for the OEMs, so this engine will fit in the same footprint as our previous platform. This engine platform was designed with consideration for both current and future emissions regulations.”

The new 11 L and 13 L engines are dual certified for EU Stage V and U.S. EPA Tier 4 Final and will meet Korean Tier 5 and China Stage IV. There are also versions for lesser and unregulated

emission countries.

“One benefit to us making engines for on-highway and off-highway is that we can use the components and experience from all of the applications to build the products that the customer needs,” said Kohring. “We found that the compression release brake that we have for the trucks today is a really good fit for wheeled industrial applications. Now we have this engine brake as an option for industrial engines and we can help our customers improve their braking performance.”

For marine applications, Scania showed its new 13 L DI13 marine engine developed for propulsion and auxiliary use at the international maritime industry trade fair SMM in Hamburg, Germany, in September 2024.

Based on the new generation platform, the company said the new engine is fit for a wide range of applications, including downsizing from higher-size alternatives. The engine complies with current IMO Tier III emission standards and is compatible with biodiesel blends and HVO fuels. The new marine propulsion engine has a power range of 350 to 1,050 hp (257 to 772 kW) for IMO II and IMO Tier III, and 350 to 950 hp for US EPA Tier 3.

Mobile versions of the company’s battery electric storage system (BESS) shown at Bauma in Germany can be used to charge electric or electrified machines on a work site. These can be recharged when needed at a remote location and returned to support machine charging. Larger permanent installations using multiple units can be used as backup power for critical infrastructure, including data centers.

The integration-ready BESS features battery packs already used in off- and onhighway applications, meaning that it is already certified for transportation.

In recent application news, the company said its D5 U.S. EPA Tier 4 Final/Stage V dual-certification offroad diesel engine will power J&S Manufacturing’s entire portfolio of equipment for mining applications in North America. The engines have already been installed in a boom truck and scissor lift trucks used in underground mines in Northern Ontario, and more Volvo Penta-powered utility vehicles will follow. The engines will be supported by Wajax, Volvo Penta’s distribution partner based in Ontario, Canada.

Volvo Penta said its engines are optimized for mining applications and certified by the Mine Safety and Health Administration (MSHA) and CanmetMining. The D5 has service intervals of up to 1,000 hours and the company said all of its engines are designed based on the same platform, which simplifies everything from installation to service and the acquisition of spare parts.

In its marine business, Volvo Penta announced an expanded three-year global warranty with terms for commercial marine operators measured by years or total operational hours, whichever comes first. This new warranty applies to products delivered from 2025

onward and covers Volvo Penta branded transmissions, engines, control systems and accessories.

POWER RANGE

GASOLINE: 5 to 25 hp

GASEOUS FUEL: 15 to 400 hp

Zenith Power Products has been busy over the past several years. The company moved its headquarters and engine production from Abingdon, Va., to

Tomahawk, Wis., in 2020 and with that came a renewed focus on the gaseousfuel engine platforms that were core to its business. During that same year, the company’s owners brought on Lee Oberto as Zenith’s president, an engineer with a resume that includes work with Caterpillar’s 3600 large bore engines and as a professor at Michigan Tech.

Today, the company is in the process of doubling the footprint of its dedicated factory (a former Harley-Davidson plant) in northern Wisconsin, and there are already plans in the works for a third expansion.

Oberto said the company needs to increase its footprint to help it keep pace with the demand of its current products, including its popular Zenith NAG416 spark-ignited 1.6 L gaseous-fuel engine line. Based on a water-cooled gasoline engine sourced from Hyundai Motor Co., the powerplant can be found in equipment ranging from concrete pumps, generators, air compressors and even a special-purpose vehicle designed for traveling across frozen lakes.

The factory expansion in Tomahawk is also required to ensure it is ready for new engine sizes that Zenith has under development.

First up will be 2.4 and 3.4 L natural gas and propane engines for industrial applications and power generation. In development for two years, these are diesel-based engines developed for prime power, continuous duty and standby applications.

The company’s NA665, an inline six-cylinder 6.5 L engine, has also been popular. “We sell a lot of these engines in West Texas for vapor recovery in natural

gas compression, and we do some power gen and a lot of irrigation applications with it,” said Mike Samoorian, who joined Zenith in a sales role in 2017.

Oberto said testing is complete on 2.4 L and 3.4 L engines, each based on HD Hyundai Infracore (HDI) diesel engines that are popular in forklifts, and they will be the next to join the Zenith line up. Both engines use a fuel system from EControls along with other changes.

The inline four-cylinder 2.4 L engine is available in two fuel options, or dual fuel. P24 (for LPG) is rated 45 kWm at 2,500 rpm or G24 (LNG) is rated 39 kWm at 2,500 rpm. The larger inline four-cylinder 3.4 L engine is rated 55 kW at 2,500 rpm for the P34 (LPG) or 49 kW at 2,500 rpm for the G34 (LNG).

“We’ve got some of these out there in the field right now running, and they’re pushing 10,000 hours now,” said Samoorian. “The customers have said, ‘We haven’t done anything. We’ve just changed oil in them.’ It’s a fantastic engine. It’s got hydraulic lifters so there’s no maintenance on the head, which is great in pump applications or generators where it’s just expected to run. The ones we have out there now are in a continuous-duty application. They’re on vapor recovery in gas compressors so they just run and run and run. It going to be a really good product for us.”

“Our product launch road map includes a lot of new engines, and the 3.4 L and 2.4 L are just the first two,” said Oberto. “We’re planning five or six new launches in the next three years. Soon, we will have engines in our catalog that range from 1.6 L to 24 L. There is a lot of stuff happening, and we have the financial commitment we need to develop the engines.

“We’re also excited about the engineering relationships we have with our suppliers like HDI, with which we have access to the engineers who actually do the heavy lifting. It’s amazing, because that access completely changes how we can develop a product. We have the support of hundreds of engineers.” PP

Company

hosts “world premiere” of new engine series plus next-gen eDrive demonstrator.

By Becky Schultz

Motorenfabrik Hatz (Hatz) announced a “world premiere” at Bauma 2025 in Munich, Germany, with the unveiling of its new F-Series engine family. The new engines fill a gap in the company’s product portfolio by adding displacements from 0.95 to 1.75 L.

“There was something missing in our portfolio still for superior diesel engines,” said Bernhard RichterSchützeneder, director Sales & Service Global, Hatz, during the unveiling.

“The new series of engines is positioned between our existing 1B-Series and D-Series which go up to 11 kW and the H Series that start at 18.4 kW.”

Though just three of the new models were on display, the F-Series encompasses four engines for mobile machines and six targeted for generator applications, with U.S. EPA Tier 4 Final and EU Stage V variants available. Power ratings range from 7.5 to 18.4 kW (10.1 to 24.7 hp).

The F-Series completes the engine range for both Hatz and its customers.

“Many times, we didn’t have something to offer under 25 hp. So, [customers] might be using Hatz’s

bigger engines, but on the small side, they’d have to use something else,” said Michael Hartoonian, president and CEO, Hatz North America, who was on hand for the unveiling. “Now we get to complete that range for everybody and keep people 100% Hatz.”

The new engines are currently available for sale with most already in stock.

INTERNALLY DESIGNED, BUILT AND SERVICED

The smallest model in the F-Series is the 3F30 at just under 1 L displacement. The three-cylinder engine provides 15.8 kW (21.2 hp) at 3,000 rpm or 7.5 kW at 1,500 rpm for 50-Hz generators.

The 3F35E is made from the same engine block but offers 150cc more displacement at 1.1 L. “Thanks to the electronic speed control, it’s compliant to EPA Tier 4 Final and EU Stage V and it develops 18.4 kW at 3,000 rpm and only 110 kg of weight,” said RichterSchützeneder. “This engine is built as a complete open power unit… a robust design, heavy-duty power pack which has been completely designed and built by Hatz and is completely serviced by Hatz.

“That’s a significant advantage for machine builders and users,” he continued. “And the electronics, the cooling circuit, the air circuit and the complete exhaust system are made by the engine manufacturer with international warranty and service.”

The third engine displayed on the stand was the 3F45E, also shown as a complete open power unit. The threecylinder, Tier 4 Final-compliant engine has a 1.3 L displacement with electronic speed control and is rated 18.4 kW at 2,500 rpm for Tier 4 Final. Its “sister” engine, the 3F45, is rated 18.4 kW for EU Stage V with a mechanical governor.

“As a generator engine, the power output of the 3F45E is 14.2 kW (19 hp) at 1,800 rpm and the 3F45, the mechanical version, provides 11 kW (14.8 hp) at 1,500 rpm,” RichterSchützeneder noted.

Two additional models in the family not shown at Bauma were the 4F45 and the 4F45E four-cylinder engines with 1.7 L displacement. “These models are totally dedicated to generator purposes, so they are only available as fixed speed operation and they provide 16 kW (21.5 hp) at 1,500 rpm and 18.4 kW at 1,800 rpm,” said Richter-Schützeneder.

DROP-IN SOLUTION

Development of the new engine series was the result of a collaboration between the different branches of Hatz.

“The American engineering team developed a solution and the German team developed a solution, and then we brought the best things together into production,” Richter-Schützeneder explained. “If you bring both sides together, you can make a solution that fits for both markets.”

Other branches of the company, such as Hatz Netherland, were also involved in the F-Series’ development. “It was a joint approach,” said RichterSchützeneder.

Because there are already numerous engine options available in this size class, Hatz chose to focus on “re-motorization projects” with the F-Series.

“Every time we can sell an engine, we have to replace a competitor. And how do you do that with the most compact size, because if it doesn’t fit in a machine, it doesn’t fit in a machine,” Richter-Schützeneder commented.

So, Hatz’s engineering team identified a size limit for the new engines to

ensure they could fit within a specified footprint with minimal modification to existing machines. “What we wanted to have, and what the market wanted to have, is a drop-in solution for the customer segments that we are addressing now,” said RichterSchützeneder.

Also essential was keeping things simple. “Innovation is our tradition. That’s what our motto is,” RichterSchützeneder stated. “But at the end of the day, the customer is always right. And in this power class, the customer wants quiet engines at a low price… If they want a big machine with high performance, they come to us for the H50 product line, and then they are willing to pay for extra.

“Of course, we will offer [on the F-Series] all the additional features that we have, like IoT and things like that, but being a mechanical product, the benefit of it is not what it is on bigger power classes.”

NEXT-GEN CONCEPT CUBE

Hatz’s tradition of innovation did prove central to the development of the eDrives featured in the Bauma stand. They were presented in the form of the Concept Cube 2.0 demonstration machine.

who previously served as director of Research & Development for Motorenfabrik Hatz.

“We analyzed the technology on the one side, but on the other side, we had a close look at the machine itself to understand the compaction business. And we analyzed the customer needs.

Cube, shown at Bauma 2022, represented Hatz’s vision for the future of vibratory soil compaction. The latest iteration brings that vision to life, with a full-size working model demo’ed in an outdoor exhibit area at the 2025 event.

“We have been working on electric drives for three to four years. We analyzed the strengths and weaknesses and designed the drivetrain with this knowledge,” said Dr. Sebastian Wohlgemuth, the recently appointed

“We brought it all together in the Hatz eDrive system and what you can see here at the booth are the real components, which will be our scope of delivery in the future,” Wohlgemuth said at the machine’s unveiling. “This system will be the future of soil compaction.”

Two versions of eDrives were displayed: one with two motors for forward and backward movement similar to a traditional reversible plate

on each motor, meaning no losses and high efficiency,” said Wohlgemuth.

(Read “Hatz Components provides precision machining” on the Power Progress website at https://t.ly/qB6QL.)

A PERFECT FIT

The upper part of the Concept Cube 2.0 houses the inverters and the control unit, which are utilized to electronically synchronize the motors.

“That’s also part of [Hatz’s] scope of delivery,” Wohlgemuth said. “We developed our own inverters and control unit… because the available inverters and control units are not programmable in such a deep layer that you can fast and precisely control the position of the imbalances.”

Fortunately, Inecosys, a provider of customized hardware and software solutions based in Munich, joined the Hatz family in 2021. Its product experts supplied the necessary experience in electronics development, calibration and software solutions.

“We had the opportunity to enlarge the R&D department of Hatz with these people with a different knowledge. It’s a perfect fit,” said Wohlgemuth. “And we also now expanded the business of Inecosys in April with a new CEO and more topics.

“It’s new technology for Hatz,” he acknowledged. “It’s nice that we have the opportunity for Hatz Components to be part of that by machining some parts for the drive concept. In the global picture, that shows all the knowledge and capabilities that we have in the Hatz Group.

Development of the F-Series was the result of a collaboration between the different branches of Hatz.

THERMAL & ACOUSTIC INSULATION TECHNOLOGY

“That’s also good for our customers, because they’re not just buying a single part. We also have the expertise in the background to support our customers.”

BEYOND COMPACTION

In addition to what was shown by Hatz, Japanese manufacturer Mikasa and Sweden-based Swepac showed vibratory compactor models at Bauma equipped with Hatz eDrives. The OEM customers will be among the partners aiding in further product development prior to field testing with end users to obtain their feedback.

The aim is to have eDrives in series production by the time the next Bauma rolls around in 2028. Once this is achieved, the company anticipates moving beyond compaction to other machine forms.

“We started with the compaction business as we know the business very well and it has an important market share for us,” said Wohlgemuth. “It’s a very rough business and with the huge forces on the machine and the parts, it’s very challenging.

“When we show that we are capable of controlling the motors and creating a robust system under these conditions, we can do [that for] every machine,” he continued. “So, it’s a hard application as a starter, but it fits perfect to Hatz.” PP

FPT Industrial puts the packager first in its approach to power gen engines.

By Becky Schultz

Engines targeted to power generation need to incorporate specific features to ensure they can operate effectively under wideranging load conditions. While some suppliers have chosen to adapt existing engine lines to gen-set applications, Max Meegan, head of North America Sales, said FPT Industrial, a brand of Iveco Group N.V., is taking a different approach.

“Our line of engines is specifically for power gen. It’s different components, it’s a different part number than our industrial engines,” he stated. “We make a specific line of power gen engines because that’s what separates us – taking the time to understand the journey of the power gen packager and building it.”

This requires an

installation into existing gen-set designs is important, as well, especially for those selling into global markets. “The Tier 4 Final ATS components are the same size and space claim as our Stage V,” said Meegan. “So, if you want to start selling to Europe and you only export 10 [gen-sets] a year, I’m not going to make you redesign a whole unit to do that. I have the same thing that fits in the

have an optimal power to weight ratio, with the 2.8 L engine offering the performance of a 3.4 L in a package smaller than some competitors’ 2.2 L models.

“If you understand the idea of the packagers’ journey, that matters,” he continued. “When you have the smallest radiator, it matters. When you look at some of our aftertreatments – when you look at the DOC (diesel oxidation catalyst) on the 2.8 L… and say ‘that’s super tiny’ – that matters.”

It also counts where that

DOC is mounted. “A lot of people just mount the DOC on the flywheel. But they don’t understand gen-set manufacturers – that’s where the alternator goes,” Meegan noted. “They don’t want the ATS down there. They want it above. So, on our F28 engine, we have the ATS mounted up.”

Seamless integration and

To enable customers to grow their businesses and expand into other markets, FPT Industrial intends to continue to grow its power gen offering.

“Complexity has cost, and engine suppliers don’t want to keep as many engines anymore… We’re doing the opposite of what’s happening in industry right now,” said Meegan. “Our message is

In other words, FPT Industrial seeks to be a one-stop shop for power generation. “The average packager has several vendors to make a lineup. It’s rare to have an engine line where you can say you’re good in all these different power nodes. That’s what we desire to be,” Meegan stated.

He added: “You can realistically use us from 30 kW to 500 kW without having to sacrifice because I try to give you a great cost option; I give you all the same technology on every engine... If you’re a packager, that’s how we separate ourselves.”

FPT Industrial continues to launch new internal combustion engines (ICE) to meet customer needs, including models for nonregulated markets. On the other end of the spectrum, the company has multiple solutions to address the growing need for ecofriendly

alternatives.

For example, on the ICE side, its XC line of engines are compact, requiring less material to build while producing more horsepower; they also offer multiple fueling options. “We see that as a short- to mid-term need that all the engines have to get smaller with more power, more alternative fueling options,” said Meegan. “Even something like that is much more sustainable.”

Alternative fuel compatibility across the engine lineup takes that a step further. “Whether it’s ethanol, sustainable diesel, renewable diesel, methane –we have that as pretty much standard operating procedure on all our engines.”

BUILDING BRIDGES

For those seeking even greater emissions reduction potential, FPT Industrial’s ePowertrain division, based in Turin, Italy, offers a portfolio of solutions, including batteries, e-axles, e-transmissions and hydrogen fuel cells.

FPT Industrial seeks to be a one-stop shop for power generation.

But not everyone is at that stage yet. Customers are often seeking a bridge solution because they’re not yet ready to move into the more advanced systems that the ePowertrain division has to offer.

“People are encouraged that we’re still investing in the current [engines] and we have this mid strategy that’s about alternative fuels… things that are really relevant today, which I think has a very good bridge potential,” said Meegan.

He emphasized that FPT Industrial is willing to allow its customers to take that journey at their own pace.

“The journey is going to be when people are ready. I’m not under pressure to say ‘I have a battery. You must convert or now I will cut you off by this day.’ We have it. We build out our lineups through our products and our sister companies… so the products are there.

“If you approach me and say, ‘Max, I’d like to buy a battery’ – here’s my lineup, it’s off the shelf. Let’s do the journey together.’ I take what I have and I’m going to make it work for you and make sure you choose the right thing,” Meegan assured. “You don’t have to start a development project with me, because I have it all done.

“That, in essence, is a big difference. That makes me the packager, but who helped me with developing is my own company, and now I’m the expert packager for you.” PP

A look at two new products. COMPACT CONTROLLER

MRS Electronic, a provider of smart electronic solutions, has presented its new CANopen version of the proven CAN I/O CC16WP, a compact controller.

The company has offered CAN controllers with an integrated CANopen stack for several years. The new variant of the CAN I/O series functions as a CANopen slave and can be addressed via a higher-level controller (CANopen master), such as via CODESYS. There is no need to program the controller, the company said, which will save time and simplifies commissioning.

The CANopen stack used is based on the proven CiA 401 device profile which the company said enables standardized and seamless integration into existing CANopen networks. In addition to a high degree of flexibility during configuration, the company said users will benefit from significantly simplified error diagnostics. Errors can be quickly detected, localized and rectified.

The new CAN I/OCC16WP offers:

■ Eight current-controlled PWM outputs (2.5 A per channel at 85°C)

■ Six multifunctional inputs

(configurable as digital or analog inputs)

■ Two CAN interfaces (CANopen and CAN FD compatible)

■ CAN wake-up function from standby

With its robust, compact housing (protection class IP6K8) and the proven plug connector, which MRS Electronic said it is ideal for use in harsh environments with limited space. PP

GROWTH IN CANADIAN TRACTOR SALES

According to recent data from the Association of Equipment Manufacturers (AEM), Canadian sales of agricultural tractors grew 3.4% in April year-to-date, while sales of four-wheeldrive tractors jumped 46.3% during the same time frame.

U.S. sales dropped in all categories in April 2025, with total agricultural tractor sales down 13.3% and combines falling 48.3% year-to-date.

“The April report of slow tractor and combine sales is reflective of the overall softness in the ag economy. Increased input prices, high interest rates, and global trade concerns are leading to farmers taking more of a cautious approach to their capital investments,” said Curt Blades, senior vice president of AEM. “With planting season underway, we remain optimistic the ag economy will improve,

leading to a strengthening of the ag equipment market.”

CELEBRATION OF CONSTRUCTION

AEM along with nearly 40 member companies, trade groups, and industry stakeholders, brought the U.S. construction sector to the heart of the nation’s capital for the 2025 Celebration of Construction on the National Mall.

Over three days, the event showcased the equipment and technology that are building infrastructure, modernizing

communities, and advancing economic growth.

By hosting the Celebration of Construction on the National Mall during this week, AEM and its partners worked to spotlight the value of the workforce and the innovations transforming how infrastructure is built.

More than 15,000 attendees, including lawmakers, students and families, saw the role equipment manufacturers have in keeping America competitive on the global stage and creating careers.

“This event is a powerful reminder of how essential the construction equipment industry is in building a stronger America,” said Megan Tanel, president and CEO of AEM.

The event presented more than 80 pieces of construction equipment, from excavators and cranes to compact loaders and utility vehicles, along with interactive educational displays. PP

AEM is the North Americabased international trade group representing off-road equipment manufacturers and suppliers, with more than 1,000 companies and more than 200 product lines in the agricultureand construction-related industry sectors worldwide.

AEM said the equipment manufacturing industry in the United States supports 2.3 million jobs and contributes roughly $316 billion to the economy every year.

Starting with the May 1935 issue, Diesel Progress – or Power Progress as it’s known today – has covered engines and engine-powered equipment. Through those nine decades, the writers and editors of this publication have witnessed the adoption of technology that was considered science fiction in the 1930s, and they’ve praised (as proper non-biased journalists) the entrepreneurs, executives and especially the engineers that made that progress possible. It’s been – and it continues to be — an amazing thing to watch. Throughout 2025, we are celebrating those 90 years. With this department, we’re going back to some of the unique applications, forgotten firms and companies that have been part of the industry and this media company since the beginning of both.

SUGAR INDUSTRY IN HAWAII GOES 100% DIESEL

Diesel Progress editor Bruce Wadman was traveling in Hawaii when he got an opportunity to “look around” Oahu Sugar Co. Ltd.’s plantation on Oahu.

“The sugar cane fields were being harvested at the time, and it was a spectacular sight to see the completely mechanized manner in which the cane is harvested and delivered to the mills,” he wrote. “Diesel equipment is used exclusively in the entire operation from cutting the cane to hauling and dumping it into the bins that convey the cane into the mill that converts it into raw sugar.

“In 1948 Oahu Sugar Co. started switching from rail hauling of cane from fields to the mill with steam locomotives to diesel truck hauling. Half the plantation was converted in 1948, and the process of changeover

to truck hauling for the whole plantation area was completed in 1950. This is one of the latest plantation conversions to diesel truck cane-haulers – a trend that has been sweeping over most of the island plantations.

Truck hauling operations have been going on in … other plantations in Hawaii ever since World War II. The plantation built and maintains 178 miles of roads.

“Twelve Oshkosh Model W-2209M tractor trucks and semi-trailers are the newest equipment that Oahu Sugar Co. has put into operation to haul cane. These huge cane-

haulers can carry a payload of 30 tons and are powered by Cummins 300 hp Model NHRBS-600 supercharged diesels. Hans L’Orange, the manager of Oahu Sugar Co. plantation, who has been with the company since 1911 … is satisfied with his new all diesel operation and strikes a praiseworthy note at the efficiency and trouble-free operation of his newest diesel equipment.

“'The equipment, engineered for the type of land and weather conditions encountered in the fields,' he said, 'has proved itself to be sound in design and very satisfactory in operation.'

“The use of diesel trucks in cane hauling is more economical and efficient than rail hauling for a number of reasons: 1.) the diesel equipment is much more flexible. If it rains in one part of the plantation, the trucks can be moved to another dry section with a minimum of

time lost, whereas with rail operations, the tracks had to be taken up and moved to another field. 2.) the diesel cane-haulers bring the cane to the mill quicker and in a much fresher state. 3.) less manpower is required, and the fuel and maintenance costs are much less than in rail operations.”

When Wadman visited, Oahu Sugar had been in operation 54 years and had 12,000 acres in cultivation and 400 pieces of equipment in its fleet. It closed in 1995. The sugar mill and its 170 ft. smokestack was restored and is home to the YMCA of Honolulu. PP
