Abstract

The increase in the volume of vehicles resulted in a crisis of fossil fuels so there is a need for alternative fuels to replace gasoline. Butanol and Diethyl Ether (DEE) are alternative fuels that can be added to gasoline. This is because the Octane Number and high O2 levels optimize combustion in the cylinder and increase torque and power and save fuel. This study compares the addition of butanol and DEE to gasoline on torque, power, and Brake Specific Fuel Consumption (BSFC). The study used a 160cc gasoline engine with a carburetor with engine speeds of 1000, 2000, and 3000 rpm. Variation of fuel mixture 5%, 10%, and 15% on gasoline. The results showed that the DEE15 mixture increased the highest torque by 28% at 3000 rpm compared to other fuel mixtures. Engine power also increases the highest by 28% when using a mixture of DEE15 compared to other fuels. Meanwhile, BSFC experienced the highest decrease of 19% when using the DEE15 mixture compared to other mixtures.

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.

Abstract

The use of gasoline in vehicles produces CO, HC, and NOx emissions which are dangerous for the environment. Using butanol and ethanol as additional gasoline can reduce pollutant emissions. This is because alcohol has a high oxygen content and helps combustion more completely. This research compares the Exhaust Gas Temperature and Emissions results of EFI engines using gasoline-butanol and gasoline-ethanol. The EFI engine used has a capacity of 150CC. The alcohol used was butanol and ethanol with a percentage of 5%, 10%, and 15% in each test. The test results showed that the highest EGT reduction occurred in the E15 mixture at 23.98% and B15% at 8.65. Meanwhile, CO emissions experienced the highest reduction in E10 by 53.6% and B15 by 44.6%. HC emissions also experienced the highest reduction in E15 by 70.5% and B15 by 66.7% compared to gasoline. However, CO2 emissions increased to 17.07% in the E15 mixture and 11.46% in B15. This proves that the addition of ethanol produces more complete combustion than the addition of butanol.
