One main focus in vehicle development is CO2 reduction (Figure 1). In order to meet this goal a further increase in engine efficiency will be required. The optimization of the combustion process will play an important role. Therefore combustion influencing parameters like valve angle, intake port layout, piston surface and combustion chamber layout need to be optimized. Upcoming efficiency technologies for gasoline engines, e.g. Exhaust Gas Recirculation (EGR), Miller cycle, etc. will drive new, more challenging requirements for the combustion system. A fundamental understanding of the correlation between geometrical and combustion performance data is essential and will require a sophisticated development process comprising extensive 1D- and 3D-simulation, component testing and complete engine testing.
