In this paper an estimation of efficiency potential of the engine process with Gasoline Direct Injection (GDI) is presented as well as both the advantages and todays problems of different mixture preparation concepts for the GDI engine. Furthermore examples of combustion analysis with optical measurement methods like Particle Image-Velocimetry (PIV) and spectroscopy techniques, which are important for future development steps in GDI, are shown and discussed. A validation of the numerical simulation of the stratified combustion process with data, obtained experimentally from a GDI engine, is performed and discussed. Consequently the combination of experimental and numerical methods provides both a better understanding of mixture preparation and combustion processes in GDI engines as well as an efficient development procedure for an optimized mixing and combustion process for future GDI engines.
