Abstract: In the present work, transesterification is used to synthesise biodiesel. The biodiesel has been tested in variable compression ratio (VCR) engine. The experimental investigations have shown the compression ratio of 17.5 as the most favourable compression ratio because it provided accurate results of the emission and performance analysis. The performance analysis was measured by changing the load in relation to the mechanical efficiency, brake thermal efficiency and brake specific energy consumption. The volumetric efficiency and brake thermal efficiency were found to be 79.17% and 25.97% at compression ratio of 17.5. The emission analysis has been studied for carbon dioxide, carbon monoxide, nitrogen oxides, hydrocarbon and smoke. The results were found comparable with diesel fuel.
