The invention relates to an internal combustion engine, especially one with spark ignition and possibly with a catalyst. On the one hand a new design is proposed and on the other this invention can be applied in certain versions to existing spark ignition engines. The main aim is to reduce the emission of pollutants and/or increase the efficiency. This is achieved by the invention by the blowing of gases which may also contain fuel into the combustion chamber. This primarily generates a controllable, efficient turbulence in the combustion chamber (especially during combustion). The mixture is preferably blown in in pulses and its quantity is controllable depending on the working point. Thus especially cold-starting and warming up and the partial load range of the internal combustion engine are to be improved. In addition, it is proposed to produce a stratified charge by the blowing process. |
