| 摘 要： | 介绍了将LPG应用在小型点燃式发动机上时 ,对燃烧系统参数优化和稀薄燃烧能力的影响。试验在一台四冲程、水冷 1 2 5ml单缸摩托车发动机上进行。研究结果表明 ,压缩比和点火提前角的增大有利于恢复发动机扭矩 ,火花塞间隙调整对扭矩影响不明显 ;提高压缩比、增加点火提前角和加宽火花塞间隙将有利于LPG在发动机中拓宽稀薄燃烧区的范围

| Abstract: | This paper presents the effects of combustion parameters on the performance and lean burn of LPG for small SI engine.The experiments are carried out in a four stroke,water cooled,and 125cc motorcycle engine.The results of the test show that the increment of compression ratio and advanced spark ignition will benefit to recover the torque output,but the gap of spark plug has no clear effect on the torque output.The increments of compression ratio,the advanced spark ignition,and the gap of spark plug will enlarge the lean burn range of LPG. |
