【 摘 要 】

The sources of fossil fuels in the world are limited, driving many researchers to seek alternative solutions for fuel. In particular, there is great interest in using unconventional fuel sources for vehicles. One of the main important sources of renewable fuel is bio-fuel, and alcohol is the most appropriate type of this resource. Both ethanol and methanol are good additives to gasoline in vehicles because of the improvements they offer to combustion characteristics and engine performance. In this paper, the influence of Ethanol (ranging from E10 to E30) and Methanol (ranging from M10 to M30) as additives to gasoline are investigated in terms of improvements to the combustion characteristics and performance of the engine, in this instance, a one-cylinder, four stroke, 11kW output power IC engine. In this experiment, performance tests were carried out for brake torque, power, thermal efficiency, and consumption of specific fuels. The flue gases, including CO, HC, and CO2 were measured and analysed under different operating conditions with various engine speeds, ranging from 1,500 to 3,000 RPM. The results demonstrated that the thermal performance of the IC engine was improved in the E10 combustion case (10% ethanol and 90% gasoline). It was also revealed that HC and CO concentrations were significantly reduced with increases in the concentration of ethanol in the fuel mixture. The combustion characteristics of methanol-gasoline fuels were not as good as those for ethanol-gasoline fuels.
