ABSTRACT:
An internal combustion engine with a nozzle for injecting fuel into the cylinder under pressure and across a heater which ignites the fuel as it enters the cylinder. A variable volume pump with a longitudinally movable control lever for varying the fuel volume provides fuel to the injector nozzle. A gear drive connects the pump with the engine crankshaft. The gear drive is operable in response to engine speed to change the phase relationship between the crankshaft and pump operator thereby controlling the timing of the injection of fuel into the cylinder. In one embodiment a pair of movable racks operate to control a plurality of levers to control a plurality of pumps.
