The present work examines the oxygen enrichment on diesel engine at the fuel side and air side. Oxygenation at the fuel side is done by blending the Dimethyl carbonate (DMC) additive with a maximum percentage of oxygen whereas that of air side is done by coupling a blower to the inlet manifold. The experiment was conducted with four different blends of oxygenated additives with diesel, and then the effects of supercharging in these blends were analyzed. The performance and emission characteristics of DMC blend with diesel fuel were examined and compared with the base engine characteristics. The results show that for 5% of DMC there is an increase in the thermal efficiency of the engine and decrease the CO emissions.

Abstract


The present work examines the oxygen enrichment on diesel engine at the fuel side and air side. Oxygenation at the fuel side is done by blending the Dimethyl carbonate (DMC) additive with a maximum percentage of oxygen whereas that of air side is done by coupling a blower to the inlet manifold. The experiment was conducted with four different blends of oxygenated additives with diesel, and then the effects of supercharging in these blends were analyzed. The performance and emission characteristics of DMC blend with diesel fuel were examined and compared with the base engine characteristics. The results show that for 5% of DMC there is an increase in the thermal efficiency of the engine and decrease the CO emissions.
