LPG—汽油双燃料发动机试验研究

An Experimental Research on Dual-Fuel Engine of LPG and Petrol

选用奥华液化石油气有限公司生产的汽车用石油气燃料供给装置配于EQ61 0 0 -Ⅰ型发动机进行性能测试分析。试验表明 ,在不改变原机压缩比和点火提前角时 ,燃用LPG的动力性下降了 ,最大功率为原机 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。

The fuel equipment of Petroleum Gas of AoHua LPG Co.,Ltd was used on EQ6100-I engine to construct dual-fuel engine to analyze performance. The results show,without modifying the original engine feature,the power performance of combusting LPG was decreased, the maximum power was 90% and the peak torque was 92% of original engine.Fuel consumption ratio of LPG was lower than petrol,the rate of saving power was about 5%.
