ABSTRACT:
A process is proposed for exhaust gas aftertreatment by afterinjection of fuel in a diesel internal combustion engine with a precatalyst and a particulate filter, in which process the afterinjection NE is performed as a function of the temperature in the area of the precatalyst Tcatand of the state of charging of the particulate filter. Since this process operates with especially high efficiency in heretofore critical short-distance operation of diesel internal combustion engines, the strict requirements of future legislation relating to exhaust gas emissions can immediately be met.
