It is simple and advisable as well as efficacious to improve the dynamic and economic properties of two-stroke motorcycle petrol engine by means of exhaust dynamic effect. In this paper, the exhaust pipe design method and the effect of some exhaust system factors on the exhaust dynamic effect are researched into by test for the exhaust systems of the two models of motorcycle engines. Under several operating conditions, exhaust pressure waves are measured respectively at the different points on the exhaust pipes of variously designed sizes. Having analysed the measured exhaust pressure waves and the results simulatively calculated, the relative problems to reasonablely utilize the exhaust dynamic effect of two-stroke motorcycle petrol engines are discussed in some detail.
