The performance characteristics of a four-stroke, single-cylinder, variable compression ratio engine were investigated fueled with esterified pongamia pinnta oil. Transesterification process is used for preparation of methyl ester from pongamia pinnta oil [PPME]. Experiments has been conducted at various loads like 0, 3, 6, 9 and 12 kg with engine speed of 1500 rpm for varying compression ratios from 14:1 to 18:1 and at common injection pressure of 200 bar. The affect of compression ratio is investigated on fuel consumption, performance parameters and exhaust gas emissions. The compression ratio is varied with changing the clearance volume by movement another piston in opposite direction with the help of screw rod and hand wheel mechanism. The performance characteristics like BSFC, brake power, MEP, brake thermal efficiency and exhaust gas temperature are analyzed for PPMEDiesel blends in the variable compression ratio engine. The emission characteristics like carbon dioxide hydrocarbon, nitrogen oxides, carbon monoxide, and smoke level are also measured for PPME-diesel blends in the same engine. The motivation behind this analysis is to fix the effective compression ratio of the engine for this blend fuel.
