Lean Mode During Idling For Reduction Of The Number Of Particles

摘要

An operating method for an apparatus, having an internal combustion engine that can be operated in a lean mode and a stoichiometric mode, a crankcase, at least one combustion chamber and preferably a throttle element via which charge air can be fed from a charge air cooler to the combustion chamber internal combustion engine is switched to a lean mode during idling and is operated in the lean mode, with the result that, in particular, the pressure difference between the crankcase and the combustion chamber is reduced.

1. An operating method for an internal combustion engine configured to be operated in a lean mode and a stoichiometric mode and having a crankcase, at least one combustion chamber, comprising:
switching the internal combustion engine to a lean mode during idling mode; and operating the internal combustion engine in the lean mode such that a pressure difference between the crankcase and the at least one combustion chamber is reduced.
