| 摘 要： | 通过试验分析了发动机转速、负荷、压缩比、点火提前角以及火花塞间隙对稀薄燃烧的影响,优化了稀薄技术条件下压缩比、点火提前角等参数。试验表明,稀燃技术使电控LPG发动机经济性、排放性和动力性优于原LPG发动机,排放性和经济性远好于汽油机,动力性接近汽油机。

| Abstract: | By the experiment,the influences of engine speed,load,compression ratio,spark advance angle and spark-plug gap on lean-burn were analyzed.The parameters like compression ratio,spark advance angle and so on under the condition of lean-burn were optimized.The experiment shows that the electronically controlled LPG engine with lean-burn technology has better emission,economy and power performance than the original LPG engine,whose emission and economy are far better than those of gasoline engine and whose powe... |
