Fuel injection occurs via a pumping plunger within the fuel pump. The stroke of that plunger determines the mass of fuel to be injected. When the plunger starts to move, a needle valve within the injector is closed and the fuel pressure in the fuel line rapidly rises to a. value that ultimately lifts the needle valve ofl" its seat allowing fuel to be injected into the combustion chamber (Hofbauer and Sator, 1977).
