Abstract: The compression ratio on heat distribution in an exceedingly variable compression ratio engine. The compression ratio powerfully affects the operating method and provides an exceptional degree of management over engine performance. Variable Compression quantitative relation (V.C.R) engine check rig is employed to see the result of Compression ratio (C.R) on the performance and emissions of the engine and also the distribution of warmth during a variable compression ratio engine. The performance frequency parameters like efficiencies, power adopted, and specific fuel consumption square measure determined. Further, combustion development is additionally discovered through this work, we will notice the optimum compression ratio that the simplest performance is feasible. So as to search out optimum compression ratio, experiments were dispensed on one cylinder four stroke variable compression ratio diesel motor. Tests were dispensed at compression ratios of fifteen, 16, 17.5, 19 and 21 at totally different masses the performance characteristics of engine like Brake power (BP), Brake Thermal potency (BTE), Brake Specific Fuel Consumption (BSFC). Results show a major improved performance at a compression ratio twenty one. The compression ratios lesser than 21 showed an increase in brake thermal potency, come by fuel consumption. The warmth is that the governing issue that operates whole engine and turn out power. Compression ratio between 19 to 21 provides optimum results in distribution of unaccounted heat also improves thermal performance of engine, Each fuel within the world is employed to supply certain quantity of warmth by either mechanical or chemical action. The heat is created by fuel is employed to reciprocate piston within combustion chamber and this reciprocatory motion is regenerate to movement power to regulator by exploitation crank and rod mechanism.
