Variable Compression Ratio (V.C.R) engine test rig can be used to determine the effect of Compression Ratio (C.R) on the performance and emissions of the engine. The combustion phenomena, when provided with a pressure transducer. The performance frequency parameters like efficiencies, power adopted, and specific fuel consumption are determined. Further, combustion phenomenon is also observed through this work, we can find the optimum compression ratio for which the best performance is possible. In order to find out optimum compression ratio, experiments were carried out on a single cylinder four stroke variable compression ratio diesel engine. Tests were carried out at compression ratios of 16.5, 17.0, 17.5, 18.0 and 19.0 at different loads the performance characteristics of engine like Brake power (BP), Brake Thermal Efficiency (BTE), Brake Specific Fuel Consumption (BSFC). Results show a significant improved performance at a compression ratio 19.0. The compression ratios lesser than 19.0 showed a drop in break thermal efficiency, rise in fuel consumption.
