A Numerical Simulation of the Working Process of Diesel Engine

Abstract:

Based on the in-cylinder hydrokinetics and by coupling the multidimensional model of in-cylinder combustion and verifying the rationality of the computational model, this thesis uses KIVA-3V program, which has been added a new subprogram, to provide a numerical simulation of the in-cylinder pressure, the temperature and the NO_X distribution and emission of a diesel engine in different injection advance angles, so as to analyze the change of in-cylinder pressure and temperature, and to find out the rules of temperature distribution, the NO_X distribution and emission condition. This thesis is of guiding significance to the better understanding of the performance of diesel engines and to the optimum design and research of the diesels.
