M15甲醇汽油排放性试验研究

摘要

对M15甲醇汽油和纯汽油在JM419Q-ME发动机上进行了经济性试验，分别绘制负荷为30%、50%、80%下的速度特性曲线，并对其结论进行了分析。试验结果表明：该发动机燃用M15甲醇汽油与燃用纯汽油相比，低负荷、低转速时，燃油消耗率有所提高；高转速时，燃油经济性有所下降；中等负荷时，燃油经济性相差不大；高负荷时，经济性有所下降。%The paper gives some research and analysis on the JM419Q-ME engine for its economy performance by running M15 methanol gasoline and pure gasoline and draws the speed characteristic curves when the load at 30%,50%,80%.From the experiment and analysis,the results were comparing with pure petrol using the mixed fuel at lower speed and lower load,and a smal increase in the fuel consumption rate,at higher speed,there were a little decrease in the fuel consumption rate.At moderate load,only less increase in the economy performance.At higher loading,there were a little decrease in the economy performance.
