GHG17 Aftertreatment System
The GHG17 Aftertreatment System (ATS) is an airless dosing system. The
Selective Catalytic Reduction (SCR) system consists of an Aftertreatment Control
Module (ACM), a tank for Diesel Exhaust Fluid (DEF), a DEF pump, an airless
DEF dosing unit, and an SCR module. DEF is pumped to the airless dosing unit
through a high pressure DEF line at 10 bar (145 psi). The DEF dosing unit injects a
fine mist of atomized DEF into the SCR module to produce a chemical reaction.
This chemical reaction converts nitrogen oxides (NOx) present in the exhaust
stream into water vapor and nitrogen.
The SCR inlet temperature and Diesel Particulate Filter (DPF) outlet pressure
sensors have been eliminated for the GHG17 1-BOX™ ATS configured units. A
Soot Probe has been added to the 1-BOX™ ATS configurations. A Sensor Control
Unit (SCU) (2) has been added to the ATS and is directly wired to the Soot Probe
(1).

The GHG17 platform will continue with Hydrocarbon (HC) Dosing (regeneration
when the unit is driving over the road). A DEF-to-fuel ratio should be
approximately 4.3%. Due to a change in fueling strategy, the driver may notice a
change in engine noise during HC Dosing on the DD13 and DD15 platform.
