Abstract: In this study, the performance, combustion and emissions characteristics of compression ignition engine were calculated and analysed using a waste agricultural biodiesel . The tests were performed at steady state conditions for a four-stroke single cylinder diesel engine loaded at engine speed of 1500 rpm. The present experimental investigation evaluates the effects of using BD20 blend of biodiesel. During experimental testing of CI engine using biofuel blend, the engine was maintained at various compression ratio i.e., 18, 19 and 20 respectively. Engine load is varied from zero to full load condition. Design of experiment is done with Taguchi method. The main objective is to check the optimum compression ratio and to obtain minimum specific fuel consumption, better efficiency and lesser emission with higher compression ratio. Results shows that Brake thermal efficiency and cylinder pressure of CI engine increases with increase in compression ratio and load. Specific fuel consumption, emission of hydrocarbon and carbon monoxide decreases as we increase compression ratio. Nitrogen oxide follows the reverse trend and found to be increased as we increase compression ratio and load on engine. The analysis shows optimum performance with lower emission at a CR of 20 and load 100%.
