EXHAUST GAS AFTER TREATMENT SYSTEM WITH TEMPERATURE CONTROL

摘要

Disclosed herein is a vehicle emission control system (300) configured to operatively receive exhaust gas from a combustion engine (110) and comprising an EATS (120) configured to operatively clean the received exhaust gas, a burner unit (130) configured to operatively heat the received exhaust gas to a predetermined temperature before the exhaust gas is provided to the exhaust gas after treatment system (120), and a pump unit (140) configured to operatively provide the burner unit (130) with air to be used by the burner unit (130) in a heating process. The pump unit (140) is configured to be operatively propelled by exhaust gas, and the burner unit (130) is arranged upstream the pump unit (140) such that exhaust gas from the burner unit (130) is operatively provided to the pump unit (140) for propelling the pump unit (140).
