Experimentation was carried out to analyze the combustion parameters of a single cylinder, air-cooled, Bajaj make, 2.2 kW BP, 3000 rpm, two-stroke, catalytic coated (copper coated on the piston crown and on the inner surface of cylinder head), methyl alcohol-gasoline blend (80% gasoline, 20% methyl alcohol, by volume) operated SI engine. The combustion characteristics, peak pressure (PP), time of occurrence of peak pressure (TOPP), maximum rate of pressure rise (MRPR), maximum heat release (MHR) and temperature of exhaust emissions at exhaust port opening (EPO) were determined at full load operation of the engine. Alcohol-gasoline blend fueled copper coated combustion chamber considerably improved the combustion parameters over conventional engine with pure gasoline operation.

Keywords: Copper coating, Methyl Alcohol Blend, PP, TOPP, MRPR, MHR, Temperature of Exhaust Gases at EPO.
