Mack, US10 Emissions Solution 165
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 2010 emission
compliant engine have an exhaust
aftertreatment system which includes
a Selective Catalytic Reduction (SCR)
system and a Conventional or TRU
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.
