ABSTRACT:
In a method of operating an internal combustion engine, in a motor vehicle in particular, fuel is injected directly into a combustion chamber of the engine either during an intake phase in a first mode of operation or during a compression phase in a second mode of operation. In this method, fuel is injected at intervals corresponding to predetermined angle of rotation distances of a shaft of the engine. The interval corresponds to larger angle of rotation distances at a high engine rpm and a high load applied to the combustion engine than at a medium or low engine rpm and a medium or low engine load.
