The study of dual fuel system applied to EFI engines

Crude oil price is increasing in recent years, besides, human damage results in unrecoverable harm in this global environment. The whole world is active to set energy saving and carbon reduction such remedial measures into action. The whole world is also urgent to seek substituent new energy resources for using. Now, hydrogen is one of the popular energy resources. The reactant of hydrogen and oxygen is only water and no carbon dioxide, therefore, hydrogen is viewed as clean energy. This study is the probe of analysis and development about using micro plasma methanol water reformers and EFI scooter engines fifth with hydrogen supply system, micro plasma methanol-water reformers can decrease the cost of producing hydrogen, furthermore, they don´t have any problems of saving and conveying hydrogen. The reactant, called syngas, of micro plasma methanol-water reformers is directly implemented to EFI scooter engines fifth to burn. The experimental result indicates that in order to gain the achievement of clean energy and new resources development, using the reactant, syngas, of Micro plasma Methanol Steam Reformers to mix gasoline fuel and then implement to engine to burn can reduce the engine consumption approximately 2.23%, BSFC roughly 14.59%, and CO, concentration of the pollutants around 1.8%.
