摘　　要：叙述了在一台 80 m L摩托车用二冲程汽油机上采用双进气口分层扫气方式的试验结果 ,其 1/4节气门开度时的最低燃油消耗率可降低 2 4.8% ,但也存在稳定运转区域变小的问题。通过模拟计算 ,分析了影响这种扫气方式的关键因素是储气道压力波的影响和WT5”BZ] The two cycle gasoline engine with double entry stratified charging can reduce engine out HC emission and improve fuel economy effectively.This paper describes the experimental results with double entry stratified charging on a 80 mL twostroke motorcycleengine whichhas achieved fuelconsumption value of 316 g/(kW·h) at 6 260 r/min quarter throttle operating condition.In comparison with the original engine of 420 g/(kW·h),a reduction in fuel consumption of 24.8%,but the operating range of engine with double entry became small.By simulation and calculation,it is revealed that the factors affecting this scavenging mode may be the pressure wave propagation in the long back transfer passage and the compatibility of the two throttle control valves.
