Abstract
An internal combustion engine for a motor vehicle is described which is provided with an injection valve with which fuel can be injected directly into the combustion chamber either in a first mode of operation during a compression phase or in a second mode of operation during an induction phase. Furthermore, the engine is provided with means for feeding back the exhaust gas into the combustion chamber as well as with a control apparatus for controlling (open loop and/or closed loop) the quantity of the fed back exhaust gas. According to the invention, the quantity of the exhaust gas, which is fed back into the combustion chamber, can be controlled (open loop and/or closed loop) differently in the two modes of operation.
