Complete combustion of methanol can reduce HC emissions by 20% ~ 50%, advanced engine design can reduce HC emissions by 90%, and particulate matter and NOX emissions are low. In addition, it has low volatility and little evaporation loss during refueling and driving. Methanol is toxic and corrosive, and its production process is from one energy state to another, so the energy utilization rate is low.
Methanol gasoline refers to M-series mixed fuel partially added with methanol and co-solvent of methanol fuel. Among them, M 15 (adding 15% methanol to gasoline) clean methanol gasoline can be used as vehicle fuel, which can be used in various gasoline engines respectively, and can be used instead of finished gasoline without changing the existing engine structure, and can be mixed with refined oil. Methanol mixed fuel has good thermal efficiency, power, start-up and economy, and has the characteristics of emission reduction, fuel saving, safety and convenience.
According to different national conditions, countries all over the world have developed methanol gasoline with different blending ratios, such as M3, M5, M 15, M20, M50, N85, M 100, etc. At present, commercial methanol is mainly M85 (85% methanol+15% gasoline) and M 100. The performance of M 100 is better than that of M85, and it has greater environmental protection advantages.
