LPG-汽油双燃料发动机试验研究

选用澳华液化石油气（LPG）有限公司生产的汽车用石油气燃料供给管理配于EQ6100－I型发动机，改装成LPG－汽油双燃料发动机，进行性能测试分析。试验结果表明，在不改变原机压缩比和点火提前角时，燃用液化石油气的动力性下降，最大功率为原机的90％；最大扭矩为原机的92％。燃用LPG比燃用汽油的当量比油耗低，节能率在5％左右。怠速排放试验表明，燃用LPG的CO，HC排放浓度分别为燃用贩50％和36％。

An Investigation of a Gasoline and LPG Dual Fuel Engine

The experimental engine is a dual fuel engine that is a EQ6100-1 engine made by resembling LPG fuel system into it in order to probe some questions relatively. The experimental results show that, compared with gasoline engine, LPG engine has a lower brake power, 90% lower peak power, 92% lower maximum torque and cut specific fuel-consumption by about 5%, carbon monoxide compound by 50%, and carbon hydrogen compound by 36%.
