ABSTRACT:
A pilot fuel injection system for a diesel engine. One embodiment of the system includes a high pressure fuel pump, an accumulator, a mechanical fuel distributor, a pair of fuel metering valves for each cylinder of the engine, a fuel injection nozzle for each cylinder, and an electronic logic system for controlling actuation of the metering valves; in a second system embodiment a pair of the metering valves supply fuel to all of the engine cylinders. Several embodiments of the metering valve are disclosed, some of which allows exclusion of the mechanical fuel distributor from the system. All of the disclosed metering valves meter fuel from the pump to the nozzles by traversing a passage in a valving member across another passage. Motion is imparted to the valving member by electromagnetic means which are energized by the electronic logic. The logic is responsive to engine speed and throttle position.
