Simulation and experimental investigations of a direct-injection combustion system for high speed - high performance engines 2009-32-0045

This publication presents the development of a GDI combustion system for high speed - high performance engines. The paper describes the development of the combustion process and its results, the development methodology, covering 1D and 3D CFD simulations, and shows extensive experimental investigations. With 3D CFD simulations the necessary deeper insights in the mixture preparation process of a homogenous GDI combustion system are gained.
The findings of the simulation are transferred to an injection and combustion system for a 4-cylinder test engine. The results of the experimental investigations of the 4-cylinder engine equipped with GDI technology show the potential of GDI applications for high performance engines.
