| Abstract: | The simulation software of internal combustion engine is used to simulate the combustion process of electronically controlled common-rail diesel engine.The influence of injection pressure and injection advance angle on the formation of NOx and soot are studied.The result shows that the injection pressure and injection advance angle have a great effect on the quality of atomization and fuel-air mixture,and consequently influence the combustion and emission.The simulation technique has a direction value for optimizing injection parameters,combustion process and decreasing engine emission. |
