Abstract

The invention relates to a method for regenerating a particulate filter in the exhaust system of a diesel engine, an increase in the temperature of the exhaust gases being brought about by post-injection of fuel. The intake pressure (MAP) and/or the air mass flow rate (MAF) are reduced as a function of the ambient temperature of the engine and preferably also when the engine load is low by throttling the engine. In this way, the proportions of burned or unburned post-injected fuel can be stabilized.
