| 摘 要： | 为降低4108LPG发动机有害气体排放量,采用了CIC公司提供的当量空燃比闭环控制系统、三效催化转换器净化排气。在进行排放试验后,提出了合理调整点火提前角、空燃比,提高三效催化转换器总的净化效果的新设想。通过大量的调整试验,最终使得各工况空燃比比较理想,有害气体排放量大幅度降低。

| Abstract: | In order to reduce harmful gas emission of the LPG engine410 8,the closed loop control system of equiv-alent air fuel ratio and the three-way catalyst converter offered by CIC company are used.Based on emission test results,the new concepts of rationally adjusting advance angle and air fuel ra tio and improving overall purification effective ness of the three-way catalyst converter are put forward.By a great number of adjusting and tests,the idea l air fuel ratios under different engine operating modes are gotten and then ha rmful emissions are reduced evidently. |
