Abstract
The article presented is concerned with studying the effect of ethanol, and iso-butanol concentrations in a spark ignited, single-cylinder four-stroke engine on the engine parameters such as performance, combustion, and emission. The engine performance characteristics such as specific fuel consumption, brake thermal efficiency, and in-cylinder pressure were examined for different engine's operational loads. Similarly, the emission parameters such as CO, HC, and NOx were analyzed. Results showed that the influence of iso-butanol and ethanol improved the thermal by 6% than that of petrol. As a result of adding iso-butanol and ethanol with petrol, fuel consumption reduction can be observed. The CO, NOx, and HC emission were noted as 1.25% by vol, 146 ppm, and 175 ppm, respectively, whereas the CO2 is noted as 7.7% for 5% ethanol and 15% Iso-butanol. The optimum concentration of iso-butanol and ethanol was found as 15 and 5%, respectively, which improved the engine operating parameters and decreased the emission produced. The emission such as CO, Nox, and HC shows a significant reduction; on the other hand, the CO2 showed a drastic rise for the optimized blend proving the progression of complete combustion.
