ABSTRACT:
A fuel injection system for single or multiple cylinder internal combustion engines comprises two fuel injection valves for each cylinder of an engine. One fuel injection valve operates to inject a principal volume of fuel and the other a secondary volume of fuel into said cylinder. The two injection valves are fed by a plunger which is reciprocable in the working chamber of a pump body. The working chamber of the pump body communicates with a fuel admission duct, a delivery duct for the delivery of a principal fuel volume to the one fuel injection valve and a delivery duct for the delivery of a secondary fuel volume to the other fuel injection valve in such a manner that the duct for the delivery of the principal fuel volume is covered by the plunger after the same has completed a predetermined part of its stroke.
