分层进气二冲程汽油机排放的试验研究

The Experimental Investigation on Emissions in Stratified Charge Two-stroke Gasoline Engines

介绍分层进气二冲程汽油机排放的试验研究结果,讨论了汽油机的空燃比、浓混合气进气比例值对HC和CO排放浓度的影响,以及HC和CO随功率、转速的变化关系,分析了分层燃烧的排放效果。结果表明,分层进气二冲程汽油机可以较大幅度地改善废气排放。

This paper describes the experimental investigation result on emissions in stratified charge two- stroke gasoline engines. The effect of A/F value, proportion value of the thick admixture air on HC, CO emissions, power, revolutions per minute are discussed. It was found that by stratified charge, beth the fuel economy and emissions may be improved greatly.
