    摘要：对Santana2000AJR型电控汽油机改装为LPG/汽油两用燃料发动机进行了试验研究。结果表明:燃用LPG较燃用汽油,最大功率降低6%,最大扭矩降低12%。节能率最大可达9%,污染物排放中HC、NOx和CO最大降低分别为60.9%、70.6%和90%。通过分析比较,提出LPG发动机的改进方法。

    Abstract: Introducing the bench experiment of LPG/gasoline bi-fuel engine refitted from Santana 2000 AJR electronic control gas engine.The experiment results show that,compared with gasoline engine,LPG engine has a lower brake power,6% decreased maximum power,12% decreased maximum torque and cut specific fuel-consumption ratio by about 9%,carbon hydrogen compound by 60.9%,Nitrogen oxygen compound by 70.6% and carbon monoxide by 90%.By analysis and contrast,the promoted measures of LPG engine were put forward.

    Keywords: LPG;LPG/gasoline Bi-Fuel Engine;Emission;Promoted Measure
