Abstract

Air pollution is increasing due to the high exhaust emissions of motorized vehicles using fossil fuels. The solution is the use of alternative energy. Butanol and Diethyl Ether (DEE) are alcohols that can be used as a fuel mixture and are environmentally friendly. This is because butanol and DEE have high oxygen levels so the oxidation process in the combustion chamber increases and the residual gas results from combustion is better. This study tested the residual gas from the combustion of a 160 cc gasoline engine using a mixture of pertalite-butanol and pertalite-DEE fuels with 5%, 10%, and 15% alcohol percentages. The test results show that adding DEE produces better engine exhaust emissions than adding butanol. CO emissions decreased by 87% using DEE15 while B15 reduced CO by 72%. DEE10 improves HC by 73% while B15 improves HC by 72%. However, DEE15 increases CO2 by 17% and B15 by 11%. Meanwhile, the oxygen content increased by 8% in DEE15 and 6% in B15 compared to pure pertalite.

Abstract

Community economic activities that encourage motorized vehicles are getting higher. This exacerbates dependence on fossil fuels and air pollution. The outside air that is contaminated with exhaust gases from combustion products is very dangerous for human health. Motorized vehicles such as motorcycles are the largest cause of air pollution. Alcohols have high octane number and low viscosity. The use of ethanol and methanol alcohols is very diverse, so they are easy to obtain. Therefore, alcohol ethanol and methanol are suitable as premium fossil fuel mixtures. This study aims to observe the CO and HC emission characteristics of the gasoline engine using a premium-alcohol mixture of ethanol, methanol. The alcohol concentration was varied from 5% to 15% at 5% intervals. The petrol engine is operated at 2000, 3000, and 4000rpm. Commercial Gas Analyzers are used to measure CO and HC emissions coming out of the exhaust. The results of the observations present the CO and HC emissions of the engine with premium-ethanol fuel, methanol is lower than pure premium (P100). CO emissions from PE15 fuel decreased to 66,30%, and PM15 decreased to 90,63%. Meanwhile, PE15 fuel HC emissions decreased by 58,94%, and PM15 decreased by 68,60%.

Abstract

The development of butanol as a gasoline additive is encouraged by the government to reduce pollution and the fuel crisis. This is because butanol is a green fuel that is environmentally friendly and can be produced. In addition, the octane number and high oxygen concentration in butanol optimize engine performance and improve exhaust emissions. This research correlates engine power and Brake specific fuel consumption (BSFC) with the BTE of gasoline-butanol-fueled engines and identifies the content of Nox compounds in exhaust gases through engine Exhaust Gas Temperature (EGT). The percentage of butanol in gasoline is 5% -15%. Engine speed from 1000-3000 rpm. Dynotest is used to measure BTE while the thermocouple is used to measure exhaust gas temperature. This research proves that the addition of butanol increases energy absorption which is converted into power with effective fuel consumption which means BTE increases. The highest BTE increase was 21.7% in the B15 blend. EGT decreased by 8.6% in the B16 mixture compared to B0. This identifies that the concentration of Nox in the exhaust gas also decreases.
