An experimental study was conducted on a compressed ignition engine using safflower biodiesel for performance and exhaust emission optimization based on a response surface methodology and desirability function approach. In this study, the effects of different engine speeds and blending levels of biodiesel and diesel fuel on the performance and emission characteristics of a diesel engine were investigated. The optimized responses (brake power, brake‐specific fuel consumption, carbon monoxide, hydrocarbon, and nitrogen oxide emissions) of a diesel engine operated using the ratio of safflower biodiesel to diesel fuel blends of 0%, 50%, and 100%, called SB0 (No. 2‐D diesel fuel), SB50, and SB100, respectively, were considered. Two factors affecting the responses based on the desirability function were determined: the type of fuel and engine speed. An engine speed of 1996 rpm and a blend of 36% biodiesel and 64% diesel fuel were found to be optimal values. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13034, 2019
