Computer Simulation of Fuel Injection Systems for DI Diesel Engines 922223
The continuity and momentum equations for a pump-pipe-nozzle fuel injection system have been solved by a computer simulation program employing both the Runge-Kutta method and the more widely used method of characteristics. This allows the prediction of fluid phenomena and the dynamics of the mechanical components based on the geometry of the FIE system. The simulation includes the effects of possible cavitation, system leakage as well as variations in fuel density and bulk modulus.
The computer model has been made as flexible as possible by using a modular format and inputting the system parameters from external files or dialog boxes. Experimentation was done on a Bosch VE type distributor pump supplying a multi-hole type nozzle which allowed preliminary evaluation of the model by comparing the predicted and measured injection rates and line pressures over a range of pump speeds and loads.
