Abstract
The invention relates to an internal combustion engine which is provided with a manifold from which an intake tube extends to an intake of a cylinder of the internal combustion engine, with a gas inlet valve, disposed at the intake of the cylinder, an intermittent charge valve, disposed upstream of the gas inlet valve in the intake tube and releasing or closing the intake tube subject to a switching position of the intake tube, and in injection valve for metering fuel. The temporal position of the duration of injection of the fuel is adjusted subject to a point in time at which the switching position of the intermittent charge valve is changed. In this manner, it can be ensured that the air has a high velocity of flow during injection, thereby obtaining a good mixture preparation in a simple manner.
