Aftertreatment Diesel Particulate Filter (DPF)

Caution

Use diesel fuel other than ULSD and engine oils other than - O Premium Plus (or VDS - will adversely fect ficiency and durability the Aftertreatment DPF system and the the point where the engine may not run Manufacturer ’ s warranties can also rendered void due usage improper this indicates a problem with the exhaust aftertreatment T ake the vehicle authorized Mack T ruck dealer immediately

V ehicles equipped with a 2010 emission compliant engine have exhaust aftertreatment system which includes a Selective Catalytic Reduction (SCR) system and a Conventional TRU Aftertreatment Diesel Particulate Filter

Unapproved fuel additives (including engine oil) are NOT Blends and grades ULSD are recommended and allowable for cold weather

The Aftertreatment DPF takes the place the standard muf fler , and reduces particulate emissions into the Soot and other particulate matter are collected a filter where eventually oxidized using a regeneration V ehicles equipped with a Aftertreatment DPF require the use - O Premium Plus (or VDSspecification high performance diesel engine oil and Ultra Low Sulfur Diesel (ULSD)

The exhaust aftertreatment system virtually eliminates exhaust White exhaust vapor (water condensation) may visible during a cold black exhaust smoke visible during engine https://www.truck-manuals.net/mack/

Aftertreatment Control Module (ACM)

The ACM also monitors the following values the exhaust aftertr eatment system:

•

•

•

•

W2029917

Aftertreatment DEF Dosing Pressure

Aftertreatment DEF T ank T emperature

Aftertreatment DEF T ank Level

Aftertreatment DPF Inlet/Outlet T emperature

•

•

The ACM controls the following components the exhaust aftertreatment system:

• Aftertreatment DEF Dosing Unit

• Aftertreatment DEF T ank Heater V alve

• Aftertreatment DEF Line Heaters

• Aftertreatment DEF Pump

• Aftertreatment DEF Return V alve

Aftertreatment DEF T ank Level Sensor

Aftertreatment DPF Dif ferential Pressure

• NOX Sensors

The ACM a stand alone module. Depending your configuration may mounted part the DEF tank (as shown above) a bracket near the DEF tank.

Driver W arnings and Board Diagnostics (OBD)

Board Diagnostics (OBD)

Beginning with your 2010 compliant V ehicle, Board Diagnostics (OBD) introduced. This very similar the Board Diagnostics (OBD) system that has been required passenger cars for many years.

Board Diagnostics (OBD) a system that monitors the functions emissions related components and alerts the vehicle operator any detected need for emission related repair . When the systems detects a needed repair emissions related component activates the Malfunction Indicator Lamp (MIL).

The list emissions related components can found the W arranty and Maintenance section this manual.
