| Abstract: | The wave action method simulation program ENGWA, and the data preparation program SDIP are presented in the paper.The inlet and exhaust pipe system of a 492Q gasoline engine is calculated with the ENGWA program. Validated by experimental study and an analysis cf existing problemes, a new inlet and exhaust pipe system was developed. Experimental results show that performance of the engine with the pew pipe system was improved. |
