Abstract
An internal combustion engine ( ) especially for a motor vehicle is described. The engine is provided with an injection valve ( ) with which the fuel is injected for a combustion, can be injected directly into a combustion chamber ( ) of a cylinder ( ) in a first operating mode during an induction phase and in a second operating mode during a compression phase. A spark plug ( ) is provided with which the fuel, which is injected in both operating modes, is ignited. A catalytic converter ( ) is provided for storing nitrous oxides arising during the combustion. With a control apparatus ( ), the operating variables of the engine ( ) can be controlled (open-loop and/or closed-loop) in both operating modes. A gear change into another gear stage and a switchover into the first operating mode can be carried out approximately simultaneously by the control apparatus ( ). The switchover into the first operating mode is provided for discharging the nitrous oxides stored in the catalytic converter ( ).
