摘要：Experiments were conducted to evaluate the performance and control the exhaust emissions from fourstroke, variable speed, variable compression ratio, single cylinder, spark ignition (SI) engine, with alcohol blendedgasoline (80% gasoline, 10% methanol, 10% ethanol by volume) having copper coated combustion chamber [CCCC,copper-(thickness, 300 μ) coated on piston crown, inner side of cylinder head] provided with catalytic converter withsponge iron as catalyst and compared with conventional SI engine (CE) with pure gasoline operation. Performanceparameters brake thermal efficiency, exhaust gas temperature and volumetric efficiency) and exhaust emissions (carbonmonoxide (CO) and un-burnt hydro carbons (UBHC)) were determined with different values of brake mean effectivepressure of the engine. A microprocessor-based analyzer was used for the measurement of CO/UBHC in the exhaust ofthe engine. Copper coated combustion chamber with alcohol blended gasoline considerably improved the performanceand reduced pollutants in comparison with CE with pure gasoline operation. Catalytic converter with air injectionsignificantly reduced pollutants with test fuels on both configurations of the combustion chamber. The catalyst, spongereduced the pollutants effectively with both test fuels in both versions of the combustion chamber.
