摘　　要：针对所建的某型号摩托车发动机排气系统模型,利用GT-POWER软件的DOE功能,将发动机转速分为低速、中速及高速,以排气管参数为变量,分析了排气管内径和长度的变化对发动机动力性的影响。结果表明,排气管内径对发动机功率和扭矩的影响比排气管长度影响显著,且发动机处于6000r/min时,排气管参数对动力性影响处于正、负相关的转折点上。研究内容为进一步优化摩托车发动机动力性打下基础,适应了企业的需要。Based on the motorcycle engine exhaust system of some type, using the DOE ftmetions of the GT-POWER software, the engine speed is divided into low, medium and high speed. Taking the parameters of the exhaust pipe as variables, the influence of exhaust pipe inner diameter and length changes in engine power is analyzed. The results show that exhaust pipe inner diameter affecting the engine power and torque more than the length of the exhaust pipe. When the engine is at 6000 r/ min, the exhaust pipe parameters on the dynamic effects are in a positive and negative turning point. The study is a basis for further optimization of motorcycle engine power, adapted to the needs of enterprises.
