ABSTRACT:
A fuel injection control system for an internal combustion engine utilizes a fuel injection pump in which the pump cylinder is in fluid communication with the fuel injection nozzle and a piezoelectric actuated spill valve. A cam drive actuates the pump piston to achieve a constant velocity during the pumping cycle (constant velocity relative to degrees of rotation of the engine crankshaft). An index wheel connected to either the engine crankshaft or the pump camshaft is used in conjunction with an initial position detector, angular position detector and a pump control unit to close and open the spill valve at predetermine positions of the pump piston during the pumping cycle. The pump control unit includes a computer connected to various engine parameter transducers to adjust the closing and opening of the spill valve to achieve a desired fuel injection volume.
