【摘要】 探讨了化油器式汽油机采用电控补充二次空气加三元催化器控制排放的效果。在大量试验的基础上 ,分析了由于机前补气位置不同 ,造成混合气的均匀度和各缸进气的均匀度不同 ,从而影响CO ,HC和NOx 排放的控制以及补气流量的变化对排放的影响 ,最终得到了最佳方案。更多还原

【Abstract】 This paper introduces the application of air supple device and three way catalytic converter to reduce gasoline vehicle emission.On the base of experiments, the effect of emission is analyzed by compensating air to the front of engine,at the same time, the different locations and the rate of flow about air supple device are also considered. Thus, the optimum process can be elected.更多还原
