Abstract: Pollution is one a major factor which affects the environment nowadays, resulting in green house effect and global warming. One way of increasing efficiency is by inducting oxygen into the combustion chamber since oxygen is a combustion enhancer the amount of oxygen entering into the combustion chamber if increased it would result in better engine performance and lower emissions. Oxygen can be inducted in the intake manifold by the help of an external source. This additional increase of air will affects all parameters of the engine like Brake power, emissions, and heat release but we are going to consider only Brake thermal efficiency and Oxygen in the exhaust. Load test was conducted on a compression Ignition engine for various concentration of oxygen from (21% to 27%) with an interval of 2%. This analysis shows better Brake thermal efficiency and better brake specific fuel consumption but led to a very high percentage of Oxygen in the exhaust and lower carbon monoxide (CO), hydro carbon(HC) emission..
