Summary
In order to achieve a further reduction of CO2-emissions of car engines, especially the optimization of the combustion system is in the focus. The further development of existing stochiometric spark ignition combustion systems by means of a fully variable valve train leads to a world-wide usability of this concept. In contrast, the spray-guided combustion system is the most promising realization of a stratified S.I. combustion system. Moreover, gasoline direct injection serves as a base technology for turbo-charged S.I. engines with excellent response characteristics. The further development of diesel combustion systems especially concentrates on the significant reduction of NOx raw emissions. The alternative gasoline combustion concept of the homogeneous charge compression-ignition is characterized by the assimilation of the spark ignition and the diesel combustion system with extremely low NOx raw emissions. Finally, using hydrogen as fuel for the internal combustion engine shows the way towards the CO2-free power train.
