The effects of biodiesel (from waste cooking oil) in fuel mixture (biodiesel and diesel fuel No. 2) on brake specific fuel consumption (BSFC) of a diesel engine were investigated by response surface methodology (RSM) in this study. The experiments were conducted on a four cylinder direct-injection diesel engine. The developed mathematical models by RSM were helpful to predict the response parameters and further to identify the significant interactions between the input factors on the response. Results showed that the use of biodiesel BSFC increases 18 to 24% by the using net biodiesel. Also results showed that the reduction in engine load appeared to cause an increase in BSFC which increase up to 15% by reducing the engine load.
