In this research project, combustion processes for a large Otto gas engine were developed, which can achieve a brake mean effective pressure above 30 bar, while complying with the current emissions regulations. The central points are the expansion of the misfiring limit and the shift of the knocking limit. At the LVK of the Technical University of Munich, experiments on the influencing factors and the boundary conditions for these combustion processes were carried out at a 4.77 l single cylinder research engine. At the ITV of the University of Hannover, 3D CFD calculations for the combustion processes were conducted. One focus was the development of a combustion model for the scavenged prechamber, which was validated at the optical engine setup at the ITV.     «
