Experimental investigation of multi cylinder S.I. Engine emissions by using oxygen enriched air

This research paper gives an explanation of the formation process of toxic exhaust gas components during combustion process of oxygen-enriched mixtures in SI engine. Emissions from the exhaust of internal combustion engine affects the environment globally and also it has negative impact on human health.. Various strategies have been being developed to regulate the pollution in the urban development. Increase the concentration of oxygen in the intake air is also one of the methods to reduce emissions of CO and HC. In order to reduce the emissions the oxygen was supplied at different flow rates i.e.at 3lpm, 6lpm and 9lpm.Investigation work shows that carbon monoxide(CO) emissions decreases at increased amount of oxygen concentration in the intake air but at the same time carbon dioxide (CO2) emissions increases due to proper combustion in the combustion chamber.
