Abstract: 

In this study, a numerical investigation of using Rapeseed Oil in National Diesel Engine (EFD) 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. The results from simulation showed that the increase in biofuel percentage increase thermal efficiency and decrease monoxide carbon emission. Biofuel has a lower heating value compared to diesel fuel, resulting in a lower combustion heat release and lower power. On the other hand lower heat release reduces the temperature of cylinder contents which tends to reduce nitrogen oxide. In some cases that there is an Oxygen shortage in the cylinder, the existence of Oxygen in the structure of the fuel will complete the combustion process and it may improve the combustion efficiency compared to diesel fuel. The increase in heat release due to higher combustion efficiency of biofuel may compensate for its low heating value and result in increasing the engine power and nitrogen oxide emission.
