Aftertreatment Hydrocarbon Dosing System
W2064634
The aftertreatment hydrocarbon dosing system is a part of the exhaust aftertreatment
system and is used to increase the exhaust gas temperature (EGT) needed for the
aftertreatment system. The dosing system allows diesel fuel to be injected into
the exhaust system of the engine to increase the amount of hydrocarbon (HC)
released. The injected fuel will increase the EGT by oxidation of hydrocarbon.
An aftertreatment diesel oxidation catalyst (DOC) is mounted upstream of the
aftertreatment diesel particulate filter (DPF). This elevated temperature is needed
for the aftertreatment selective catalytic reduction (SCR) system and DPF. The
HC-system shall be governed by the engine control module (ECM).
The dosing system has interfaces with a most of the vehicle's, major control systems
including the fuel system, compressed air system , exhaust system, electrical system,
control system and external mechanical interfaces.
