不同掺混比例甲醇汽油车的经济性试验研究

Experimental study on the economy of methanol gasoline vehicle with different blending ratio

试验车辆分别燃用汽油、M5、M15、M85和M100五种燃料,在120 km/h等速行驶工况下,进行燃料消耗量试验。结果表明,与燃用汽油相比,汽车燃用M100甲醇燃料的等热值燃料消耗量最低,M15稍低,M5略低,而M85最高。随着汽油中掺入甲醇量的增加,燃料费用反而降低,燃用M100甲醇燃料费用最低。

Five kinds of fuels,gasoline,M5,M15,M85 and M100,were used in the test vehicles,and the fuel consumption tests were carried out under the condition of 120 km/h running at constant speed.The results show that the consumption of isothermal fuel is the lowest,M15 is slightly lower,M5 is slightly lower,and M85 is the highest.With the increase of the amount of methanol added into gasoline,the fuel cost decreases,and the cost of burning M100 methanol fuel is the lowest.
