摘　　要：针对发动机进气系统的非线性特性,研究了三角转子发动机的进气系统特点,建立了三角转子发动机进气流量测量模型,给出了节气门和进气口处的空气流量动态方程,进而基于该测量模型,提出了歧管中脉动气流的稳压处理措施,测定了208 cm3排量三角转子发动机的进气系统特性参数,建立了基本的进气量图,为电控燃油喷射系统的开发提供了基础数据.In view of nonlinear behavior of engine intake system,the paper researched the feature of the rotary engine intake system,and a test model of intake air amount was constructed;furthermore,dynamic state formulas in throttle and admitting port in model were established.According to the model,a measure was proposed to stabilize wave motion air at intake pressure;moreover the model was used for calibration of the intake parameters of a 208 cm3 rotary engine.Finally the basic intake maps was obtained,providing very important data to the development of electronic control system for the rotary engines.
