However the emission from the engines threatens the environment seriously and they are considered as the major source of the air pollution. They are confirmed to cause the environmental problems like Global Warming, Greenhouse gases and the acid rain. The addition of an oxygenating agent into fuel oil is one of the possible approaches for reducing this problem because of the obvious fuel oil constituent influences on engine emission characteristics. This paper reviews the available oxygenated additives and compares their effect on exhaust gas emission with help of conference papers and journals. During study of available material, it is found that oxygenated additives are an effective method for reducing PM, CO and HC without significant increase in the NOx emission.The objective of the present paper is to investigate the effect of these oxygenated additives on spark ignition engine performance and emission characteristics at variable engine speed operating conditions.
