甲醇汽车燃料消耗量的当量比和替代比

简述了碳平衡法原理,并给出了根据碳平衡法得到的甲醇燃料消耗量数学模型。根据甲醇燃料消耗量与相同碳排放的汽油燃料消耗量的计算,得出甲醇与汽油的当量比为2.17。因甲醇汽车燃烧甲醇时的排放低于燃烧汽油,同一台M100甲醇汽车甲醇燃料消耗量与汽油燃料消耗量的比值要低于2.17,即替代比小于且接近于当量比。通过实车检测得出,M100甲醇汽车的甲醇与汽油的替代比在1.9～2.0之间,取1.95较为合适。

Equivalence Ratio and Substitution Ratio of Fuel Consumption for Methanol-powered Vehicle

Principle of carbon balance method is introduced briefly in the article,and mathematical model of methanol consumption is obtained based on this method.According to calculation of consumption of methanol and that of gasoline with equivalent carbon emission,it is known that the equivalence ratio between methanol and gasoline is 2.17.Since carbon emission during burning of methanol for methanol vehicle is lower than burning of gasoline,the ratio of methanol consumption and gasoline consumption of the same M10...
