Objective: To select the optimal combination of Variable compression ratio (VCR) diesel engine operating parameters using Sesbania aculeate biodiesel. Method/Statistical Analysis: The Analytical Hierarchy Process(AHP)approach is a mathematical approach used to find the optimal combination of VCR diesel engine operating parameters and the best blend of Sesbania aculeata biodiesel. Findings: It provides the alternatives and also the visualization of various criteria and their interrelations. The alternatives are ranked by measuring the criteria and their relative importance. The permanent concept helps for the better appreciation of criteria and considers the problem selection as it contains possible criteria components and their relative importance. It was found that the optimal combination of 100% load, 17.5 compression ratio and SAOME20 blend is the optimal combination of operating parameters of the VCR diesel engine. Novelty/Improvement: The best combination of operating parameters can be found systematically and logically using AHP.
