THE NUMERICAL SIMULATION RESEARCH OF HCCI DIESEL ENGINE COMBUSTION PROCESS

摘要

Homogeneous Charge Compression Ignition has become a focus of the engine combustion research. In this paper, based on the diesel engine CA4D32-09, the HCCI engine combustion process has been simulated on the PC platform. On the basis of experimental certification, the main performance parameters (such as in-cylinder temperature, pressure, heat release rate during work process, etc.) influence on diesel engine combustion is compared and analyzed. After analyzing these simulation results, the factors on HCCI combustion are studied utilizing statistical method.
