DEF

An injector which is camshaft-driven and incorporates a plunger. The plunger works in conjunction with orifices in the injection body to determine the beginning and end of injection. The plunger has a helix and is rotated by a rack so the beginning and end of injection can occur closer together or farther apart, thus shortening or lengthening the injection period and changing metering. A special pump which supplies fuel through an orifice to the injector operates at a pressure which is precisely controlled depending on the changes in engine speed.
