Abstract
An internal combustion engine in particular for a motor vehicle, which is equipped with an injection valve with which fuel can be injected either, in a first operating mode, during a compression phase or, in a second operating mode, during an intake phase, directly into a combustion chamber delimited by a piston. The internal combustion engine also has a spark plug with which the fuel injected into the combustion chamber can be ignited. A control device is present, with which the injection valve and the spark plug can be controlled. Injection of the fuel is terminated by the control device prior to ignition of the fuel. This prevents carbon deposition on the spark plug, especially when the internal combustion engine is started.
