PROCESS OF REPAIR OF EXHAUST GASES BY SUBSEQUENT FUEL INJECTION IN A DIESEL TYPE INTERNAL COMBUSTION ENGINE WITH A PRECATALIZER AND A PARTICLE FILTER.

摘要

Subsequent treatment procedure for exhaust gas by subsequent injection of fuel in a diesel-type internal combustion engine with a precatalyst and a particulate filter, in which the subsequent injection (NE) takes place depending on the temperature in the area of the TCat precatalyst and depending on the state of charge of the particulate filter, and in which the subsequent NE injection is deactivated when the temperature in the TCat precatalyst zone exceeds a maximum TRmax regeneration temperature of approximately 280 ° C.
