All the researchers have done study of engine performance parameters with addition of H2 or O2 and with turbocharger & supercharger. I have done experimentation on intake side development of SI engine. No any research should be done on injecting the oxyrich air into intake manifold by using pure oxygen. So this research to improve the performance of SI engine & reduces the amount of fuel consumption & due to complete combustion the pollution of SI engine is also reduced. Therefore the research may be done on oxyrich air for combustion of fuel in SI engine. Here I have found brake specific fuel consumption with and without oxyrich air energizer, determined brake thermal efficiency of the system. Also I have checked all emission parameters of SI engine with and without oxyrich air energizer. I could find Mechanical & Volumetric efficiency of engine with and without oxygen blending. For developing the experimental set up for oxyrich air energizer, I used computerized MPFI 4 stroke petrol engine test rig.

Keywords: Oxyrich air energizer, Specific fuel consumption, Thermal efficiency, 4 stroke petrol engine.
