In this study, a numerical investigation of using Rapeseed Oil in National Diesel Engine has been developed and validated against the experimental data. By using validated model, the effect of injection timing, exhaust gas recirculation and initial pressure on performance and emissions of this engine with three different range of using diesel and biodiesel fuels have been investigated. Biodiesel fuel has two significant characteristics, existing Oxygen Atom in its structure and low lower heating value comparing diesel fuel. The results show by increasing biodiesel fuel, better combustion process has been achieved and consequently, increasing in thermal efficiency and reducing carbon monoxide emission have been observed. Because of different characteristics of biodiesel fuel, increasing and decreasing in the amount of this fuel can effect differently on engine power and producing nitrogen oxide emission.
