FUEL INJECTION: MODELING OF THE HYDRODYNAMIC COMPORTMENT

The motor with lighting by compression requires an alimentation rigorously measured in fuel, at the precise moment and during a very short time, being located at the end of compression in the cylinder. The main objective of this work is to develop a mathematical simulation of the injection (pump ? piping - injector), while being based on the equation of the movement and the equation of the continuity, to arrive finally at differential equations that are solved by Range Kutta method. We developed a code of calculation in FORTRAN language; the results are presented under shapes of curves (pressure, flow and positions).
