Extended Idling and Aftertreatment System

Utilizing engine speed above 1300rpm recommended for vehicles which perform extended idling with active

During periods extended idling, normally greater than 8hrs, the conventional DPF system needs perform a routine conditioning cycle. The conditioning cycle controlled the Engine ECU and will start and stop automatically needed. The A conditioning required maintain normal exhaust aftertreatment system function and should not stopped. A conditioning will not occur TRU DPF systems.

Safety Information

Mack utilizes the use a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) meet A2010 emissions. The system designed require very little driver interface maintain correct operation. The technology utilizes a passive regeneration; requiring fuel injected clean the DPF . A2007 active regeneration (fuel was injected) was required clean out the DPF producing very high exhaust outlet temperatures. Certain vocational duty cycles will require the use fuel and/or a parked regeneration clean out built - soot the particulate filter . Exhaust temperatures will increase during a parked regeneration. When parking the vehicle perform a parked regeneration keep away from any flammable materials, vapors structures.

Danger

Exhaust gases and components can extremely high temperatures during regeneration. When parking the vehicle, keep away from any flammable materials, vapors, structures.

Danger

The temperature the exhaust system components during the regeneration process can exceed 350 degrees C (660 F). The exhaust gas leaving the system can reach 505 degrees C (930 F). V arious factors (including ambient temperature and duration the regeneration process) determine when these components will return normal operating temperature after regeneration has completed. extremely careful around these hot components. Contact with these components can result serious personal injury https://www.truck-manuals.net/mack/

Aftertreatment System Components and Selective Catalytic Reduction (SCR)

Exhaust

Selective Catalytic Reduction (SCR) emissions - reduction technology with the ability deliver near - zero emissions nitrogen oxides a smog - causing pollutant and greenhouse SCR’ s performance has been proved millions miles real - world trucks other well long - term field tests the U.S.

SCR reduces NOx emissions very low while the same time delivering excellent fuel economy and reliability . The system t change the design the basic Rather , SCR aftertreatment system which converts NOx the exhaust stream into harmless gases. Modern diesels already use exhaust aftertreatment called diesel particulate control emissions another soot (also known particulate matter

SCR works injecting Diesel Exhaust Fluid (DEF) into the DEF a solution ultra - pure water and DEF works with the heat the exhaust and a catalyst convert NOx into nitrogen and water vapor - two harmless and natural components the air The end result cleaner air , excellent fuel ficiency and a reliable emissions control system for s modern diesel

The Mack SCR system simple and fective, with few components. consists a Aftertreatment DEF tank positioned near the standard diesel tank, plus a Aftertreatment DEF pump, Aftertreatment DEF Dosing unit and SCR catalyst.

The advantage using DEF that enables the engine use less EGR - - and higher oxygen levels - - for better combustion, while meeting the A NOx emissions requirement 0.2 g/hpNOx. using DEF , avoid the disadvantages increasing EGR massive levels. This results better fuel economy from your Mack engine. W2055490

Caution

not put diesel fuel the Aftertreatment DEF tank. Diesel fuel, sprayed into the hot exhaust along with the DEF , could ignite explosively causing a fire resulting personal injury damage the exhaust system.

ea. Use fluids other than API certified Diesel Exhaust Fluid will compromise aftertreatment system increase and may impact your product Never dilute DEF with water any other fluid. recommended that DEF not stored extreme hot cold for prolonged Follow the instructions for proper storage and handling indicated the container provided with the purchase.

Use only Diesel Exhaust Fluid that clearly labeled meeting ISO - 22241 standards, and certified the American Petr oleum Institute. The container must display the API certification seal. Never use agricultural industrial grade

Note: Agriculture mixtures are not pure enough for use the SCR system and impurities the solution will comprise the SCR https://www.truck-manuals.net/mack/

Diesel Exhaust Fluid (DEF) Handling

When handling DEF solution, important prevent contact with electrical connections. There a risk that the DEF will cause oxidation that cannot removed. W ater compressed air not help, since DEF quickly oxidizes certain metal. a disconnected connector comes into contact with the DEF solution must replaced immediately prevent the DEF solution from creeping further into the copper wiring.

Caution

When detaching hoses and components, not spill DEF disconnected unsealed connectors. DEF spilled a disconnected unsealed connector , the connector must replaced immediately .

Things know about spilled Diesel Exhaust Fluid (DEF)

DEF solution comes into contact with the skin: rinse with plenty water and remove contaminated

DEF solution comes into contact with the eyes: rinse for several minutes and call for medical help necessary inhaled: breathe fresh air and call for medical help necessary not allow the DEF solution come into contact with other

The DEF solution not the DEF solution exposed high temperatures, breaks down into ammonia and carbon

The DEF solution highly corrosive certain metals, including copper and brass. the DEF solution spilled onto the vehicle, wipe f the excess and rinse with water . Spilled DEF solution can form concentrated white crystals the vehicle. Rinse f these crystals with water .

Note: not flush DEF spillage into the normal drain system.
