Abstract
An internal combustion engine for a motor vehicle in particular is described; it is equipped with a combustion chamber into which air is drawable through a throttle valve, into which fuel is injectable directly by a fuel injector and ignited by a spark plug during an intake phase in a first mode of operation or during a compression phase in a second mode of operation. An air-fuel mixture may be supplied to the combustion chamber through a fuel tank vent. The control unit controls and/or regulates the internal combustion engine so that in the second mode of operation, a lean air-fuel mixture is drawn into the combustion chamber through the throttle valve and through the fuel tank vent, and the lean air-fuel mixture is ignited by additional fuel injected into combustion chamber and ignited there.
