Abstract :The impact of load, Tomato Methyl Ester insert ignore into journalissuearticles values(TME);, and Exhaust Gas Recirculation insert ignore into journalissuearticles values(EGR); enriched diesel on engine performance and exhaust gas emissions was examined in this study using the Response Surface Methodology insert ignore into journalissuearticles values(RSM); optimization technique. TME blend biodiesel insert ignore into journalissuearticles values(20, 40, and 60%); and EGR insert ignore into journalissuearticles values(10, 20 and 30%); were selected to maximize BTE and minimize BSFC, NOx, CO, smoke, and HC. The engine was operated using the RSM technique by load insert ignore into journalissuearticles values(0–100%);. The results showed that the response variables were significantly influenced by load, TME and EGR concentration of engine. The results of the constructed quadratic models\` analysis of variance insert ignore into journalissuearticles values(ANOVA); suggested that each model was an appropriate fit. Additionally, an optimal was found by optimizing the user-defined historical design of an experiment. The responses corresponding to optimal study factors were load 100%, TME Blend 20 and EGR 10% gives maximum BTE of 32.5%. The fuel consumption 0.2 kg/kW.h is reduced when load 50%, TME Blend 60 and EGR 10%. Smoke and NOx emissions were decreased by 15.09% and 49.04%, while CO and HC emissions were increased by 27.54% and 21.76%
