A Review on Significant Parameters and Exhaust Emissions of Four Stroke Copper Coated SI Engine with Alcohol Blended Gasoline through Catalytic Converter

摘要

In this paper, the performance of four stroke single cylinder spark ignition (SI) engine with copper coated combustion chamber [copper-(thickness, 300μm) coated on piston crown, and inner side of cylinder head] with alcohol blended gasoline were investigated. Performance parameters like brake thermal efficiency, exhaust gas temperature and volumetric efficiency at various values of brake mean effective pressure of the engine and also investigated the combustion characteristics such as peak pressure, maximum rate of pressure rise, time of occurrence of peak pressure and maximum heat release at full load operation of the engine with alcohol blended gasoline. In this study, a comprehensive review of the four stroke copper coated spark ignition engine using alcohol blended gasoline with catalytic converter. The output power and emissions of alcohol blended engines were compared with conventional engines with pure gasoline operation.
