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.

The compression ratio has a significant role in vehicle performance. The arrangement of air entering and leaving the combustion chamber is determined by the design of the air inlet and outlet locations. The design of the combustion chamber is crucial to prevent backflow in the remaining combustion air. Backpressure is the emission of gases flowing back into the combustion chamber, causing non-stoichiometric combustion. The purpose of this research is to find the effect of compression ratio on performance and exhaust emissions of motorcycles, especially spark ignition engines. The research procedure begins with a standard piston modification process to get compression ratios of 9:1, 10:1, 11:1, and 12:1. In order to get uniform weight, pistons with low compression ratios will be equipped with holes at the bottom. Experimental data taken were; dynamometer, gas analyzer, and SFC. An increase in compression ratio causes an increase in vehicle performance in the form of torque and power. The air-fuel mixture is compressed to a smaller volume, leading to increased density. This increased density promotes better flame propagation and faster combustion. When the combustion process is faster and more efficient, there is less time for unburned hydrocarbons to be released into the exhaust gases.
