摘　　要：本文通过剖析ＹＡＭＡＨＡＹＢ８０二冲程汽油机排气管内气体压力波的传播和反射过程，探讨了传统排气动力效应系统调谐转速范围过于狭窄的原因，介绍了用调谐腔拓宽排气系统调谐转速范围的研究结果。试验表明，采用排气调谐腔能有效改善发动机在中低速区的性能。This paper analyses the propagation and reflection of exhaust pressure waves in the exhaust pipe of YAMAHA YB80 gasoline engine, discusses the cause that makes the range of tuning speed too narrow in traditional exhaust dynamic effect pipes, and then introduces the method to widen the tuning range by using a tuning chamber exhaust system. Experimental results show that the exhaust tuning chamber can improve the engine performance at the middle low speed range.
