Abstract

Continuous consumption of petroleum fuels and atmospheric pollution, have fascinated the development of clean alternative fuels using additives in fuels for better combustion in CI engine. In the current study, diethyl ether and nitromethane were used as oxygenated additives for finding the replacement of diesel with a suitable diesel–diethyl ether–nitromethane blend. For this, experimental investigations were carried out on a VCR diesel engine using diesel–diethyl ether–nitromethane blend in varying concentrations to determine the optimum blending ratio for enhancing performance and reducing exhaust emissions. The considerable performance and exhaust emissions were observed with D–DEE10–NM2.5 (diesel 87.5%, diethyl ether 10%, and nitromethane 2.5%) blend at standard engine parameters. The improvement in engine performance and reduction in emissions was found using D–DEE10–NM2.5 blend as compared to pure diesel at 100% rated power.
