AB - Nowadays, more researches focus on protecting the environment. Present  investigation concern with the effectiveness of Oxygen Enriched hydrogen- HHO  gas addition on performance, emission and combustion characteristics of a DI  diesel engine. Here the Oxygen Enriched hydrogen-HHO gas was produced by the  process of water electrolysis. When potential difference is applied across  the anode and cathode electrodes of the electrolyzer, water is transmuted  into Oxygen Enriched hydrogen-HHO gas. The produced gas was aspirated into  the cylinder along with intake air at the flow rates of 1 lpm and 3.3 lpm.  The results show that when Oxygen Enriched hydrogen-HHO gas was inducted, the  brake thermal efficiency of the engine increased by 11.06%, Carbon monoxide  decreased by 15.38%, Unburned hydrocarbon decreased by 18.18%, Carbon dioxide  increased by 6.06%, however, the NOX emission increased by 11.19%.
