Abstract
An internal combustion engine, in particular for a motor vehicle, is provided with injection valves with which fuel can be directly injected into the combustion chambers of the internal combustion engine either in a first mode during an induction period or in a second mode during a compression period. The internal combustion engine has an electronic control unit, by which the fuel quantities injected into the combustion chambers in the two modes can be open-loop and/or closed-loop controlled in varying ways. The electronic control unit is configured such that the first mode can be operated as the normal mode and the second mode as the exceptional mode. In this manner, further fuel savings are achieved in the operation of the internal combustion engine.
