| Abstract: | Computer simulation of internal combustion engine is a modern calculation method.It can reduce testing times and duration,and can save manpower,material consumption and money in the study of internal combustion engine.The whole CNG engine model is built up with AVL BOOST,and its thermodynamics process is described macroscopically.The reliability of the model is verified by speed characteristics test at full load.On the basis,the influence of main parameters on the CNG engine's performance is analyzed,and some improvement methods are put forward. |
