Ethanol fuel, performance, emission gas, coefficient of variation


As one component that may affect performance and emissions is that the cyclic variation if the cyclic variation is simply too large, the result's very influential on torque fluctuations which may reduce the engine driveability. This study examines the effect of gasoline bioethanol blends on a single-cylinder spark-ignition engine which is distributed by variations of fuels (E0, E5, E10, and E15) by adding 0.5 % vol/vol oxygenated cyclohexanol. The test results can improve COVIMEP in the cycle to cycle variations so torque fluctuations are often minimized which ends in improved engine performance (heat release), besides that emissions become better.
