ABSTRACT:
A distribution type fuel injection pump for use in a fuel injection combustion engine comprising a plunger capable of moving reciprocally along its axis and simultaneously rotating about its axis and a couple of members forming a cam mechanism having a first cam member and a second cam member. The first cam member is mounted on the plunger and the second cam member is mounted on a housing rotatably about its axis. The couple of cam members cause the plunger to reciprocally move while the plunger is rotating. The angular position of the second cam member about its axis can be controlled by a fuel injection timing control means in accordance with the engine speed. The second cam member can also turn about its axis so as to be adjusted in its angular position by a fuel injection timing adjustment when a selected operating condition of the engine, for example the engine start, is carried out.
