普通车用汽油和E10乙醇汽油对汽车尾气排放的影响调查

The Detection Analysis on Auto-exhaust of the Gasoline Used by Local Vehicle and E10 Ethanol

[目的]了解济南市使用E10乙醇汽油对汽车尾气排放的影响。[方法]于2006年2月在济南市区选取10辆汽油车,分别燃烧普通车用无铅汽油和E10乙醇汽油,检测汽车使用不同燃料时的一氧化碳(CO)、碳氢化合物(HC)、一氧化氮(NO)的排放量,对比试验结果并进行汽车尾气排放检测分析;比较使用不同车用燃料对汽车尾气排放的影响。[结果]燃用E10乙醇汽油较燃用普通车用无铅汽油,汽车排放中的CO(g/km)和HC(g/km)的排放量均有明显地减少,NO(g/km)排放量的平均值无明显变化。[结论]E10乙醇汽油对车辆尾气排放的削减作用主要对CO和HC,对NO的作用不明显。

[Objective]To find out the influence of E10 ethanol to auto-exhaust in Ji＇nan. [Methods]The chosen 10 automobiles in Ji＇nan area Feb 2006 which used gasoline or E10 ethanol respectively are detected to know such pollutants as CO,HC,NO in different fuel driven automobiles and compare the auto-exhaust influence with different fuel driven vehicles. [Results]The exhaust of CO and HC of the automobiles used E10 ethanol reduced, but the exhaust of NO is unchangeable. [Conclusion]The reduction of the exhaust of CO and HC of the automobiles used E10 ethanol is obvious, the exhaust of NO is not.
