ABSTRACT:
A fuel injection pump assembly comprises a plunger rotatably and telescopically mounted in a pump cylinder and having a plurality of fuel supply slots which are as many as the engine cylinders and movable in response to rotation of the plunger for selective communication with a pair of fuel inlet ports in the pump cylinder. The fuel supply slots are half as many as the engine cylinders and angularly equally spaced at a first angle. The fuel inlet ports are angularly spaced from each other at a second angle which is equal to the product of the first angle and [(1/2)+n (n=0 or a positive integer)]. The plunger is rotatable about its own axis in response to rotation of the engine and reciprocable in strokes which are as many as the engine cylinders per rotation of the engine for selectively supplying fuel from the fuel inlet ports through the fuel supply slots, through a pressurization chamber in the pump cylinder, and through a passageway in the plunger to fuel distribution ports in the pump cylinder which are connected to the engine cylinders via delivery valves. The fuel inlet ports are selectively opened and closed by solenoid-operated valves to disable selected engine cylinders by cutting off fuel supply thereto.
