Experiments were conducted to control the exhaust emissions from two-stroke, single cylinder, spark ignition (SI) engine, with alcohol blended gasoline (80% gasoline, 20% methanol by vol; 80% gasoline and 20% ethanol by volume) having copper coated engine [CCE, copper-(thickness, 300 μ) coated on piston crown, inner side of cylinder head] provided with catalytic converter with different catalysts such as sponge iron and manganese ore and compared with conventional engine (CE) with pure gasoline operation. A microprocessor-based analyzer was used for the measurement of carbon monoxide (CO) and un-burnt hydro carbon (UBHC) in the exhaust of the engine at various magnitudes of brake mean effective pressure. Aldehydes were measured by DNPH (dinitrophenyl hydrazine) method. CCE with alcohol blended gasoline considerably reduced emissions in comparison with CE with pure gasoline operation. Catalytic converter with air injection significantly reduced pollutants with test fuels on both configurations of the engine. The catalyst, sponge iron in comparison with manganese ore reduced the pollutants effectively with both test fuels in both versions of the engine. Methanol blended gasoline effectively reduced pollutants in comparison with ethanol blended gasoline.
