Exhaust & Aftertreatment
GEnEral Exhaust InformatIon
Kenworth will offer three main DPF and SCR exhaust systems on heavy duty chassis in 2010. A Right Hand Under DPF
and SCR system, in which both canisters are located underneath the cab access step. A horizontal system with both the
DPF and SCR located horizontally with a cross over pipe in the frame, and an Independent DPF and SCR located verti-
cally back of cab on stanchion brackets.
RH Under DPF and SCR
Horizontal DPF and SCR
Independent Back of Cab
The following images depict the typical exhaust routings for each system, and can be used to determine exhaust routing
paths for systems you choose. Dimensional information can be found in Section 5 of this manual.
Body Builders must not modify (including altering, substituting, and relocating) the DPF and SCR canisters. The exhaust
piping after it exits the SCR canister may be modified, however using smaller diameter piping or piping with numerous
bends is not recommend as the backpressure requirements of the system may be exceeded.
