The present investigation related with the enhancing of combustion phenomena of DI diesel using Oxygen Enriched Hydrogen Gas. Here the Oxygen enriched hydrogen gas was produced by the process of electrochemical reaction-electrolysis. The produced gas was aspirated into the combustion process of mineral diesel along with intake air, at the flow rate of 4.6 lpm. The results show that the fuel consumption gets decreased and simultaneously, engine-out pollutants come down by the addition of Oxygen enriched hydrogen gas with warm diesel fuel induction. When, the diesel fuel temperature was increased from 25°C to 35°C, total fuel consumption of the test engine decreased by 15.76%, unburned hydrocarbon emission decreased by 25.76%, smoke emission decreased by 33.33% and the NOx emission increased by 19.52%.
