Biodiesel is an alternative fuel for diesel engine. Considering the differences between diesel and biodiesel
fuels, engine condition should be modified based on the fuel or fuel blends to achieve optimum performance.
In this study, performance of a diesel engine using biodiesel was investigated. Different experiments
were carried out on a diesel engine using different blends of diesel and biodiesel fuels choosing speeds of
1200, 1600, 2000, and 2400 rpm. During experiments, the fuel injection pressure into cylinder was regulated
on 185, 200 and 215 bar. The results of torque and brake specific fuel consumption for fuel blends of B20,
B40, and B100 in different engine speeds and injection pressures were recorded and compared. The results
of this research work showed that increasing fuel injection pressure for fuel blends of B20, B40, and B100
increased torque about 4.9%, 6.5% and 8.1% respectively and decreased maximum brake specific fuel consumption
about 12%, 12.6% and 9.2% respectively. Also, the exhuast gas temperature and peak pressure of
cylinder were increased by increasing the injection pressure.
