Abstract

Using of energy resources could bring an encouraging influence on both atmosphere, and economy. The present paper investigates the modeling and optimization performance/emission characteristics of a single cylinder diesel engine supported with Jatropha biodiesel. The main studied parameters were EGR ratio, engine load, and IT. The engine-out parameters were BTE, EGT, CO, NOX, and UHC.  Response surface model based on historical design was used to predict/simulate the engine data. It is accomplished that the optimal value for the engine load, EGR ratio and IT were found to be ~94%, 0%, and 25 degree, respectively. At obtained optimal point, the value of BTE, UHC, NOX, EGT, and CO were predicted as around 34%, 24 ppm, 970 ppm, 380, and 0.03%, respectively. Based on the results, the RSM techniques is an efficient way to model a single cylinder diesel engine.
