ABSTRACT:
This disclosure deals with a fuel supply system for a compression ignition, internal combustion engine, which is simple in construction and inexpensive to manufacture. The system includes a plurality of fuel injectors, one injector for each combustion chamber of the engine, and a common fuel supply rail which is connected to all of the injectors. Means is provided to regulate the fuel pressure in the supply rail. The injectors are normally closed but they are sequentially actuated to inject fuel by operation of an injector control circuit. Each injector includes a pintle-type nozzle which normally is held closed by a force applying device, and the control circuit operates to remove the force applying device from each injector in turn. The nozzle of an actuated injector then opens by an amount that is a function of the pressure in the rail, and the quantity of fuel injected is related to the fuel pressure.
