Abstract

An internal combustion engine for a motor vehicle in particular is described, provided with an injection valve for injecting fuel directly into a combustion chamber either during an intake phase in a first operating mode or during a compression phase in a second operating mode. In addition, a control unit is also provided for controlling and/or regulating a fuel mass injected into the combustion chamber differently in the two operating modes. The control unit is designed so that a required air mass can be determined from a torque demand in the first operating mode, and then the fuel mass to be injected can be determined from the required air mass, and in the second operating mode the fuel mass injected can be determined directly from the torque demand.
