Abstract

The use of fossil fuels causes air pollution in Indonesia. Biofuel is one of the alternatives often used, one of which is methanol. Methanol has efficient characteristics and low emissions, increases engine performance and thermal efficiency, and reduces fuel consumption. This study aims to observe the concentration of pertamax - methanol addition of 5%, 10%, and 15% on performance, BSFC, and BTE. The percentage of pertamax and methanol fuel mixing is 5%, 10%, and 15%, and the speed used is 1000, 2000, and 3000 rpm. The measurements taken are power, BSFC, and BTE using a dynotest and displayed on a screen. Adding 5%, 10%, and 15% methanol to pertamax increases engine performance. The addition of Pertamax-methanol PM15 increases power by 25% at a speed of 1000 rpm, reduces BSFC by 40% on PM15 at a speed of 2000 rpm, and increases thermal efficiency on PM5 by 73% at a speed of 2000 rpm

Abstract

The energy crisis is largely attributed to the extensive use of fossil fuels. Butanol and ethanol can be used as an alternative energy source because their characteristics are superior to those of gasoline, such as RON and oxygen content. This study aims to determine the effect of gasoline-butanol and gasoline-ethanol mixtures on engine performance so that they can be an option to replace fossil fuels. The percentage of alcohol (butanol and ethanol) in gasoline is 5%, 10%, and 15% with variations in engine speed of 1000, 2000, and 3000 rpm. This study uses a dynamometer as a tool to measure engine performance. Test results show that E15 can increase engine torque and power by up to 26%, while B15 increases by 19%. In addition, ethanol can reduce BSFC better than butanol. The BSFC value decreased by 17% in E15, while B15 decreased by 15% compared to pure gasoline. This is because ethanol's RON and oxygen content are higher, so torque and power increase while BSFC decreases. These results prove that gasoline-ethanol is better at improving engine performance than gasoline-butanol.
