ABSTRACT:
An automated fuel injection system for a multi-cylinder internal combustion engine in which an engine digital control (EDG) receives input signals from several monitoring subsystems A-G (FIG. 4) each of which monitors a predetermined area of engine operation. The engine digital control (EDG) formulates appropriate output signals in response to the monitoring subsystems for sending by microprocessor (78) to fuel injectors (10) for control of pressurized fuel injected in the associated cylinders. Pressurized fuel is supplied by a non-engine driven pump (72) when the engine is stopped to the recirculation of fuel through the fuel injectors (10) and an engine driven pump (116) is provided to supply pressurized fuel during continuous engine operation. A pressurized magnetic control fluid is supplied by a non-engine driven pump (98) when the engine is stopped and supplied by an engine driven pump 122 during continuous operation of the engine. The fuel injector (10) has a fuel injection valve (50) and a fuel injection control valve (38) to control the flow of pressurized fuel to discharge orifices (20). Electronically controlled fluid pressure regulators (76, 118) for the pressurized fuel and electronically controlled fluid pressure regulators (112) for the magnetic control fluid are actuated by output signals from the microprocessor (78). Magnetic coils (63, 64) for valves (38, 50) are also electronically controlled by output signals from microprocessor (78) of the engine digital control (EDG).
