Abstract

An internal combustion engine (1), especially for a motor vehicle, is described, which has a combustion chamber (4) into which fuel can be injected in at least two operating modes. Each of the injections has an injection start angle and an injection duration. Furthermore, a control apparatus 18 is provided for control (open loop and/or closed loop). An injection end angle can be determined by the control apparatus (18) from the injection start angle and the injection duration. Likewise, a check can be made by the control apparatus (18) as to whether an injection interrupt angle is exceeded by the injection end angle.
