Exhaust Emission Level Reduction Process in Si Engine by Isopropyl Alcohol as Gasoline Additive

Abstract

Alcoholic fuels have some significant advantages over other alternative fuels. The alcoholic fuels can be implemented in existing engines and they have the capability of reducing greenhouse gas emissions. In this experimental analysis, the performance and emission characteristics of Spark Ignition (SI) engine using isopropyl alcohol as additive to petrol and kerosene. This experimental evaluation deals with strategically analysis of SI engine by using two different combinations of fuels. Isopropanol has been doped with unleaded gasoline and kerosene in the volumetric ratio of 10%, 20%, 30% and 40% (IPA10, IPA20, IPA30 and IPA40). It has been observed that considerable reduction in carbon monoxide and hydrocarbon emission and increased Brake Thermal Efficiency (BTE) while the NOx emission was increased. Electrical loads have been applied in the engine with bulbs of different wattages of 15 Watts and 60 Watts. In each test one fuel will be supplied and the amount of electrical load that the engine may bear will be analyzed. The performance characteristics of the engine and efficiency have been analyzed. From the result obtained it has been observed that isopropyl additive mixture will give more efficiency and more economical.
