Combustion analysis and experimental study on Copper coated piston si engine fuelled with methanol Blends with the impact of various ignition timings

Abstract

newline newlineThe improvement in the performance characteristics of gasoline engine is newlinerequired since there are a series of development in automobiles which have been newlinechanging rapidly. Different factors influence engine life. Spark ignition timings, newlinecompression ratio, alternative fuels are the main factors that cause damage and increase newlinethe emission of the engine. newlineIn the present work, experiments were carried out on four stroke, single cylinder, newlinewater cooled, constant speed, variable compression ratio (VCR) gasoline engine. The newlinework focuses on copper coated engine (CCE) thickness of 300 µm on piston crown, inner newlineside of cylinder head varying spark ignition timing 25 newlineo newlineo newlineo newlineo newlineo newline,26 newline,27 newline,28 newline, and 29 newlinebTDC at newlineconstant engine speed of 3000 rpm with 20% methanol blended with 80% gasoline by newlinevolume. The test engine was provided with a catalytic converter with sponge iron as newlinecatalyst. The performance parameters like Brake Thermal efficiency (BTE), Volumetric newline
