THE FUEL SYSTEM MODIFICATION TO STRENGTHEN ACHIEVEMENT AND THE PROSPECT OF UTILIZING GASOLINE ETHANOL BLENDED WITH WATER INJECTION

Abstract

The purpose of this research is a fuel system conversion from a carburetor to an electronic fuel injection (EFI), implementing renewable fuel varieties to save fossil fuels using gasoline-ethanol combined with water injection. Beneficial as an offer for Indonesian motorcycle environmental friendliness in terms of exhaust emissions. The goal of this study is to improve engine performance and accommodate technology for the deployment of ethanol gasoline implementations. In this study, the direct experimental method on the experimental vehicle was applied. The experiment was conducted using fuel with a ration octane number (RON) of 92, gasoline-ethanol was executed up to E25 then applied water injection (Wi). The results show that converting a conventional carburetor to EFI and additional water injection increases engine performance of 33.9%, mileage of 172%, and reduces exhaust emissions below the Indonesian government's emission standards.
