| Summary: | 碩士 === 國防大學中正理工學院 === 兵器系統工程研究所 === 89 === In recent years, the development of alternate fuels for the internal combustion engine has been motivated by both the considerations of energy shortage and environmental protection. The main challenge is to maintain engine’s overall performance and overcome the problems of metal corrosion and influence on rubber components in the fuel system.
The main purpose of this research is to evaluate engine’s overall perfor-
mance by dynamic simulation which consists of preset testing procedure.
In addition, the corrosion effect on the fuel tank with gasoline methanol is evaluated along with the microstructure observation. Three important conclusions can be drawn from this research：
(1)In dynamic tests with 10% and 25% gasoline methanol, HC and CO em- missions from the engine has been greatly reduced.
(2)The corrosion level on the tank is increased with the percentage of the methanol in gasoline.
(3)Within three thousand hours, various percentages of gasoline methanol have no substantial corrosion effect on fuel tank which consist of low carbon steel.
