甲醇汽油发动机应用性能研究

摘要

In this thesis,the application of Methanol-Gasoline Engine be analyzed from three aspects:the power, economy and emission characteristics. Then we discussed the problem of the application of Metha-nol-Gasoline Engine. Through the contrast analysis we get the results: compared with pure gasoline, the performance of the Methanol-Gasoline Engine didn’t fall, the fuel consumption increased, the emission of HC and CO reduced, after dual three-way catalytic converters, formaldehyde emission is at same level compared with the pure gasoline engine.%　　本文从动力性、经济性和排放特性等方面对客车甲醇汽油发动机的应用进行了分析，并且对甲醇汽油应用所存在的问题进行了研究，通过对比分析得出：甲醇汽油较纯汽油相比，发动机动力性不下降，燃料消耗量增加，HC和CO排放降低，经过双三元催化转换器后，甲醛的排放达到与纯汽油发动机相同的水平。
