| Abstract: | A model for a diesel engine was established with modern simulation method.Based on the calculation and analysis of engine performance,the effects of various valve overlap angles on both the internal hot EGR rate and the emissions of NOX as well as soot were found.The test results showed that the application of internal hot EGR could effectively improve emission of the diesel engine without reducing its performance on power and economy. |
