摘　　要：以里卡多软件WAVE和VECTIS为平台,对某摩托车发动机的空滤器进行了瞬态流场分析,对不同发动机曲轴转角时刻干净腔内流场分布进行研究,指出:空滤器出气管入口结构造型、入口周围环境以及同滤芯的相对位置关系对空滤器气体流通能力的影响。同时,研究发现:空滤器双出气管因进气压力脉动效应导致左右管在空滤器内出现抢气的现象,这势必会导致双缸进气量不同,从而影响发动机左右气缸性能的一致性。The motorcycle air cleaner transient flow field analysis was carried out based on Ricardo WAVE and VECTIS software, flow distribution in clean side chamber has been investigated at different engine crank angle. Results indicate that air cleaner outlet pipe entry structure, corresponding location and relative position to air filter have impact on air cleaner fluid flow performance. At the same time, left outlet pipe and right outlet pipe try to compete air in air cleaner due to intake pressure fluctuation, which lead to difference of twin cylinders intake air flow charge, thus will influence the uniform of twin cylinders’ performance.
