Abstract
A method for operating an internal combustion engine having an exhaust emission control unit with at least one exhaust emission control component which acts catalytically and/or by filtration involves operating the internal combustion engine, during a cold start or warm-up of the internal combustion engine, using a cold start engine operating process with predefined values for predefined internal combustion engine operating variables. The cold start and/or the warm-up of the internal combustion engine is controlled or regulated as a function of soot loading of a particle filter of the exhaust emission control unit.
