EXPERIMENTAL INVESTIGATION OF OXYGEN ENRICHMENT IN SUPERCHARGED DIESEL ENGINEArul Prakash R., Senthil Kumar M., Vijayanandh R., Sundararaj, K. and Raj Kumar G.Abstract The present work examines of 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 dimethyl carbonate blend with diesel fuel were examined and compared with the base engine characteristics. The results shows that for 5% of dimethyl carbonate (DMC) there is increase in thermal efficiency of the engine and decrease the CO emissions.
