Summary:

In recent years, with the development of CFD technology, numerical simulation is becoming an important method to study the in-cylinder spray and combustion process of internal combustion engine. Consequently the appropriate selection of mathematical models is very important, which will determine directly the accuracy of calculation results in IC engine numerical simulation. In this paper, the EDC and ECFM-3Z combustion model was introduced respectively, and the latter was emphasized on. Finally it was decided to use ECFM-3Z model to simulate the combustion process of a 4-valve DI diesel engine for its advantages. Through comparison and analysis, it is found that the computation results of the in-cylinder pressure peak, RoHR and emission products have excellent agreement with experimental data. Accordingly the research results show that the ECFM-3Z model reveals the DI diesel combustion process closely, and forecasts the formation of exhaust emissions accurately
