DIESEL P ARTICULA FIL TERS (IF EQUIPPED)

Y our new MACK chassis equipped with a 2010 emission compliant with engine exhaust aftertreatment system (Diesel Particulate Filter) and selective catalytic reduction (SCR) V ehicles equipped with a Diesel Particulate Filter require the use - O

Caution

Use diesel fuel other than ULSD and engine oils other than - O emium Plus (or VDS4), will adversely affect efficiency and durability the DPF system and the engine, the point wher e the engine may not run all.

Mack T rucks, Inc. fers two dif ferent types DPF systems:

• Conventional DPF (passive regeneration and parked regeneration)

• Thermal Regeneration Unit (TRU) DPF (moving regeneration and parked regeneration) well two dif ferent mounting styles:

MACK V ertical Back - - Cab DPF (both conventional DPF and TRU DPF)

MACK - Cap DPF , which a space saving unit that mounted inside the frame (conventional only)

A Diesel Particulate Filter (DPF) takes the place the standard muf fler . The DPF used meet A requirements help reduce soot and particulate emissions into the atmosphere. The particulates are removed collecting the DPF unit, where they are eventually oxidized with passive regeneration active regeneration the filter . The electrical system and exhaust aftertreatment system the vehicle will determine when regeneration required. Mack T rucks, Inc., uses two exhaust aftertreatment systems: conventional and TRU.

Conventional exhaust aftertreatment systems use passive - active

The passive regeneration process oxidizes the particulates captured the DPF while the vehicle oxidation catalyst raises the exhaust temperature approximately 260°C (500°F), the temperature which a chemical reaction takes place oxidize the soot (passive regeneration)

TRU exhaust aftertreatment systems use active regeneration. Regeneration takes place after a certain number engine operating hours and begins when air/fuel mixture injected into the thermal regenerator and raises the temperature inside the unit the point where the soot oxidation takes place.

Conventional exhaust aftertreatment systems are used highway and certain vocational TRU exhaust aftertreatment systems are used mainly refuse collection

Depending how the vehicle set up, regeneration can occur while the vehicle being driven (referred a regeneration) when the vehicle parked and idling (referred a regeneration).
