GHG14 Aftertreatment System
The GHG14 Aftertreatment Device (ATD) has changed to an airless dosing system.
The airless dosing unit no longer relies on air pressure to atomize Diesel Exhaust
Fluid (DEF) in the Selective Catalyst Reduction (SCR). The SCR system consists
of an Aftertreatment Control Module (ACM2.1), a tank for 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 nitrous oxides (NOx) present in the
exhaust stream into water vapor and nitrogen.
