Abstract
A fuel injection system for supplying fuel to an internal combustion engine includes a fuel injection nozzle having a fuel pressure operable valve member which is moved by fuel under pressure delivered by an injection pump to allow fuel to flow through an outlet to the engine. The system also includes a pump for applying a pressure to assist closure of the valve member, the fluid pressure being adjustable in accordance with the speed of the pump and the setting of a quantity control member which determines the amount of fuel supplied by the injection pump.
