Exergy analysis method has been widely used in the design, simulation and performance assessment ofvarious types of engine for identifying losses and efficiencies. In this study, the second law of thermodynamics isemployed to analyze the quality of energy in a single cylinder, 4-stroke, water cooled, and variable compression ratio(VCR) engine running with WCSFO biodiesel blend (B20). Exergy analysis includes finding of various availability suchas input availability, brake power availability, cooling water availability and exhaust gas availability. From exergyanalysis components of major exergy destruction can be found out. In this research energy analysis was carried out forB10 to B50 WCSFO biodiesel blends.B20 biodiesel blend gave better performance among all blend hence exergyanalysis is carried out for this blend to check the effect of compression ratio (CR) and injection pressure (IP) on theexergy efficiency. All possible combination of compression ratio (16,17,18) and injection pressure (180 and 200 bar)were set on the engine. It was found that engine gives higher exergy efficiency at combination CR 16 and IP 180 bar atlow and medium load and highest value was found at CR 17 and IP 180 bar at higher load condition. Also it was noticedthat exhaust gas contains higher availability than cooling water.
