This project is to determine the influence of ethanol fuel in engine emission. The main objective of this study is to compare the emission of carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC) and nitrogen oxide (NOX) produce by gasoline with the emission of carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC) and nitrogen oxide (NOX) produce by gasohol fuels which are ethanol 10% (ethanol 10% blended with gasoline 90%), ethanol 85% (ethanol 85% blended with gasoline 15%) and pure ethanol (ethanol 100%). The engine model use in this project is build up according to Mitsubishi’s 4G92 which is use in Proton Wira. The simulation is conducted by using Gamma Technologies Software (GT-Power). The relation between the increasing of engine speed with the amount of emission and the amount of emission produced by each fuel is also discussed. Major finding shows that the emission of carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC) and nitrogen oxide (NOX) decrease with the increase of blended ethanol in the fuel. Furthermore, although overall of the emission pattern results showed good agreement with previously published work even though the amount is different compare to the past studies but this is due to the engine parameters itself each engine have different parameter. The observation indicates that the emission of carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC) and nitrogen oxide (NOX) produce by gasoline is the highest compare to the other fuel. In addition, the fuel that gives the cleanest emission is the pure ethanol (ethanol 100%).
