Combustion Velocity Constant of Gasoline-Metanol-(Ethanol) Blend Using the Single Droplet Combustion Method

Abstract

Now days, the use of fossil fuels is still the most widely used energy source. This condition causes its availability to start depleting and it has an impact on worsening air quality. Biofuel can improve air problems when used as a substitute or mixture of fossil fuels. Methanol is a potential candidate because it is cheap and easy to produce. The problem of gasoline-methanol fuel blends has been solved by adding a certain amount of ethanol. But the combustion speed characteristics have not been disclosed which is one of the urgent properties of SI Engine fuel. This study aims to measure the combustion speed in a homogeneous gasoline-methanol - (ethanol) blend from previous studies. The method used in this study is the single droplet combustion method. From the test results, the speed of gasoline - methanol - (ethanol) blend burning is faster than pure gasoline, one of which is due to the micro-explosion phenomenon that accelerates the rate of combustion. The more methanol-(ethanol) blend causes the flame to become less and micro-explosion phenomena.
