A Study on Performance of Engine Combustion and Emission Using Gasoline-Methanol Fuel in Sl Engine

In recent years, the study about the high efficiency and low fuel consumption of the internal conbustion engine has been mainly proceeding. To achieve these goals, the improvement of combustion process in Sl engine and the use of substitute energy are suggested. When the methanol blend fuel Is used, the combustion rate of the initial ignition is diminishing by high latent evaporation of methanol. But it attracts the attention because of the high octane number, and lean mixture peculiarity. Considering these facts, the gasoline-methanol blend fuel In engine operation has been used to compare and analyze the pressure development, rate of heat release, mass burned fraction, and combustion process. The results of experiment show the power increase, lean combustion and low harmful component of emission.
