176 Mack, Emissions Solution
Aftertreatment Diesel Particulate Filter (DPF)
CAUTION
Use of diesel fuel other than ULSD and
engine oils other than EO-O Premium
Plus (or VDS-4), will adversely affect
performance, efficiency and durability of
the Aftertreatment DPF system and the
engine, to the point where the engine may
not run at all. Manufacturers warranties
can also be rendered void due to usage of
improper fuel. Unapproved fuel additives
(including engine oil) are NOT permitted.
Blends of No. 1D and No. 2D grades of
ULSD are recommended and allowable for
cold weather operations.
The exhaust aftertreatment system virtually eliminates exhaust smoke. White exhaust vapor
(water condensation) may be visible during a cold start. If black exhaust smoke is visible
during engine operation, this indicates a problem with the exhaust aftertreatment system.
Take the vehicle to an authorized Mack Truck dealer immediately.
Vehicles equipped with a ADR80/03 emission compliant engine have an exhaust
aftertreatment system which includes a Selective Catalytic Reduction (SCR) system and a
Conventional Aftertreatment Diesel Particulate Filter (DPF). The Aftertreatment DPF takes
the place of the standard muffler, and it reduces particulate emissions into the atmosphere.
Soot and other particulate matter are collected by a filter where it is eventually oxidized
using a regeneration process. Vehicles equipped with a Aftertreatment DPF require the
use of EO-O Premium Plus (or VDS-4) specification high performance diesel engine oil
and Ultra Low Sulfur Diesel (ULSD) fuel.
