Exhaust gas treatment system for an internal combustion engine, in particular diesel - internal combustion engine, and method for operating an exhaust gas treatment system for an internal combustion engine

摘要

A waste gas treatment system for an internal combustion engine, in particular diesel - internal combustion engine, comprises a catalytic converter arrangement (16) as well as in the exhaust gas flow path (14) upstream of the catalytic converter arrangement (16) at least one evaporator / burner - arrangement (20), wherein the evaporator / burner - arrangement (20) comprises:- a housing assembly (21) formed therein with an evaporation / combustion - chamber (22), which leads to the exhaust gas flow path (14) is open toward,- an evaporator medium (34) for receiving a liquid hydrocarbon and for the emission of hydrocarbon vapor of the evaporator / fuel - chamber (22),- a heating device (38) for heating the evaporator medium (34),- an ignition device (42) for starting the combustion of the in the evaporation / combustion chamber - hydrocarbon vapor present.
