ABSTRACT:
A fuel injection system for supplying fuel to a combustion space of an internal combustion engine includes a fuel injection nozzle having a fuel inlet and outlets which direct fuel into the combustion space. A piston is provided within a cylinder one end of which is subjected to the pressure within the combustion space. The other end of the cylinder communicates with the inlet of the nozzle and a valve is provided whereby a fuel injection pump is held out of communication with the inlet of the nozzle until the piston has moved inwardly under the action of rising pressure within the combustion chamber. During the inward movement fuel is displaced by the piston to the nozzle and this is supplied as a pilot quantity of fuel to the combustion space.
