摘要： An electronically controlled fuel supply for a diesel engine. The timing of the commencement of fuel injection into each combustion chamber is not fixed relative to the rotationsl position of the camshaft or other engine components.
A unit injector assembly associated with each combustion chamber includes a control module and an accumulator type injector module. The control module contains a solenoid valve and a hydraulic pressure intensifier. The accumulator type injector module contains an injector nozzle, a hydraulic accumulator, and a non-return valve for admitting liquid fuel under pressure into the accumulator.
In operation, an electrical control system supplies an electrical signal to the control module an appreciable portion of the engine cycle in advance of the time when fuel injection is to be initiated in the particular combustion chamber. In response to that electrical signal, the solenoid valve admits liquid fuel under pressure into the hydraulic pressure intensifier. The output of the intensifier provides a metering and intensifying chamber in which the pressure of the fuel continues to increase until near the time when fuel injection is to commence. As pressure builds up, fuel flows through the non-return valve into the accumulator. Under control of the electrical signal the solenoid valve then shuts off the flow of liquid fuel into the intensifier. The transfer of fuel under high pressure from the intensifier chamber to the accumulator is discontinued due to the non-return valve, and the injector nozzle then fires.

摘要： A pressure-controlled system for supplying compressible fuel to an internal combustion engine is electronically operated. A unit injector assembly for each combustion chamber includes a hydraulic pressure intensifier having input and output chambers, a solenoid valve to control the intensifier, and an accumulator type fuel injector which has a non-return input valve and an accumulator chamber of substantially fixed volume. In operation, a quantity of fuel is first transferred from a pressurized fuel source to the intensifier output chamber, then is further compressed by the intensifier and forced through the non-return valve into the accumulator chamber. The pressure multiplying action starts when an electrical control signal opens the solenoid valve to admit fuel from the fuel source into the intensifier input chamber, and continues progressively until the same signal closes the solenoid valve, relieving the intensifier pressure and thereby causing the non-return valve to close and the injection event to commence. The peak pressure achieved within the accumulator chamber is a function of both the source pressure and the time interval during which it is further pressurized. The mass of the injected fuel charge is determined by that peak pressure. In the operation of the system, provision is made to adjust either the pressure of the fuel source, or the time interval throughout which the further pressurized fuel flows into the accumulator, or both, in order to adjust the mass of each fuel charge that is to be injected.

The control module contains a solenoid valve and a hydraulic pressure intensifier. The accumulator type injector module contains an injector nozzle, a hydraulic accumulator, and a non-return valve for admitting liquid fuel under pressure into the accumulator. In operation, an electrical control system supplies an electrical signal to the control module an appreciable portion of the engine cycle in advance of the time when fuel injection is to be initiated in the particular combustion chamber. In response to that electrical signal, the solenoid valve admits liquid fuel under pressure into the hydraulic pressure intensifier. The output of the intensifier provides a metering and intensifying chamber in which the pressure of the fuel continues to increase until near the time when fuel injection is to commence. As pressure builds up, fuel flows through the non-return valve into the accumulator. Under control of the electrical signal the solenoid valve then shuts off the flow of liquid fuel into the intensifier. The transfer of fuel under high pressure from the intensifier chamber to the accumulator is discontinued due to the non-return valve, and the injector nozzle then fires.
