In view of existing problems in the process of applying methanol fuel to vehicle engine, a methanol synthesis test and evaluation system was established, and its application research was carried out. Study on the inter-solubility of methanol and gasoline, the characteristics of corrosive metal and nonmetal swelling factors was conducted, the effects of which on the parts in fuel supply system from fuel tank to fuel injector were tested. And the testing and analysis of power, fuel economy, emission performances and reliability of methanol gasoline engine and vehicle were completed. The research results indicate that the methanol synthesis test and evaluation system can fully evaluate the methanol application characteristics on the vehicle engines. Adding appropriate solvent can improve the physical stability of methanol gasoline and its water resistance. Methanol gasoline has corrosion effects on metal and strong swelling effects on nonmetal material. The power performance, fuel economy and emission performances of engine fueled with methanol gasoline and its vehicle are improved. Engine fueled with M15 methanol gasoline has good reliability.
