ABSTRACT:
The subject fuel injection means, disclosed herein with one of various types of internal combustion engines with which it may be employed, comprises a fuel pumping plunger, the pumping stroke of which is controlled by an inclined surface of a manually operable slide element. Said plunger is urged in a pumping direction by fluid pressure applied thereto from compression generated in the engine's combustion chamber and is spring biased in a non-pumping direction. A solenoid, operationally timed to the rotation of the engine's crankshaft, coacts with the pumping plunger to assure starting of the plunger's pumping stroke in proper timed relation to the compression and firing of an explosive charge in the engine's combustion chamber. In said pumping stroke, the plunger closes a fuel inlet to a related pump chamber and forces fuel from said pump chamber, past a one way check valve and into the engine's combustion chamber.
