Abstract: This paper reports performance evaluation of four-stroke, single cylinder spark ignition (SI) engine with methanol blended gasoline (20% methanol, 80% gasoline, by vol) having copper coated engine [copper (thickness, 300 ΒΌ) coated on piston crown and inner side of cylinder head] provided with catalytic converter with sponge iron as catalyst and compared with conventional SI engine with gasoline operation. Brake thermal efficiency increased with methanol blended gasoline with both engine types. Copper-coated engine showed improved performance than conventional engine with both test fuels. Catalytic converter with air injection significantly reduced pollutants with both test fuels on both engine types.
