Abstract

     This research presents fuel injection rate measurement with high pressure diesel injection system
(Common Rail) at fuel injection pressure simulated real engine conditions. The investigation of relationship
between fuel injection rate for diesel and palm biodiesel was studied by Zeuch’s method. This work aims
to study influence of energizing duration and fuel injection pressure with results injection rate, energy
contents, average speed and Reynolds number.
     The results showed that increase fuel injection timing results in increased fuel injection, but as the fuel injection pressure increases, the injection volume is greater than the fuel injection time. The lower
energy content of biodiesel due to lower fuel heating value and injection quantity. The average fuel
injection rate and the Reynolds number of palm biodiesel are less than those of diesel due to increased viscosity of palm biodiesel. The fuel flow resistance and consequently the effect of fuel dispersion decreases. The way to reduce the amount of biodiesel fuel has done by increasing the fuel injection pressure to reduce
the fuel injection resistance.
