摘要： The present invention relates to engines having common rail fuel injection systems. In traditional common rail fuel injection systems, each fuel injector utilized by the fuel system includes its own solenoid. These individual solenoids must cooperate to ensure that the proper amount of fuel is being injected from each injector at the proper time. Having individual solenoids requires a multiple number of moving electrical components. In contrast to the traditional common rail fuel injection system, the fuel injection system of the present invention includes fuel injectors that are controlled in operation by a common electronic actuator that is positioned remote from the fuel injectors. Therefore, the present invention reduces the number of moving electrical components in the fuel injection system by reducing the need for individual solenoids for each fuel injector.

摘要： The present invention relates to common rail fuel injectors, and includes an example of such an injector, a fuel injection system employing such an injector, and a method of injecting fuel. The fuel injector includes an injector body, a fuel pressurization chamber, a nozzle chamber, a needle control chamber, a needle control spill outlet, a fuel inlet, and a nozzle outlet. The present fuel injection system includes a source of intermediate pressure fuel, a low pressure fuel reservoir, a needle valve, a flow control valve, and at least one of the present fuel injectors. The method of injecting fuel consists of the steps of injecting fuel at an intermediate pressure at least in part by fluidly connecting the injector's nozzle chamber to an intermediate fuel source, and injecting fuel at a high pressure at least in part by exposing a pressure intensifying element to the source of intermediate pressure fuel.

摘要： The present invention relates to engines having common rail fuel injection systems. In traditional common rail fuel injection systems, each fuel injector utilized by the fuel system includes its own solenoid. These individual solenoids must cooperate to ensure that the proper amount of fuel is being injected from each injector at the proper time. It is believed in the art that a reduction in the number of moving or electrical components in the fuel injection system can improve robustness of the system. Therefore, the fuel injection system of the present invention includes fuel injectors that are controlled in operation by a common electronic actuator that is positioned remote from the fuel injectors.

摘要： A fuel injection system of an internal combustion engine includes: an injector having a hydraulic control chamber controlling the delivery of fuel through the injector, an actively controlled first valve system controlling the pressure relief from the control chamber, movable between: a first position in which the first valve system closes the injector by deterring the pressure from being relieved from the control chamber through the first relief circuit, and a second position in which the first valve system opens the injector by allowing the pressure to be relieved from the control chamber through the first relief circuit. A second relief circuit allows the pressure to be relieved from the control chamber through the second relief circuit. The second relief circuit includes a second valve system passively controlled by the fuel pressure and movable between two positions deterring or allowing the pressure to be relieved from the control chamber through the second relief circuit.

摘要： An internal combustion engine fuel injection system of the type having a plurality of fuel injection valves which are operated so that continuously pressurized fuel is intermittently supplied to each of the injectors by a distributor. The fuel injection control system further includes a novel flow control circuit for operating each of the fuel injectors, the flow control circuit being a bidirectional flow control circuit which controls the flow of fluid to and from the actuator of the fuel injector. The flow of fluid in one direction through the flow control circuit controls the rate of closing of the fuel injection nozzle while the flow of fluid in the opposite direction through the flow control circuit controls the rate of opening of the fuel injection nozzle.

摘要： An object of the present invention is to obtain a consistently stable needle lift damping effect in an injector 8b for fuel injection. In an injector 8b that relieves fuel pressure inside a pressure control chamber 37 and lifts a needle valve 36, there are provided a damper member 62 that is slidably mounted to the needle valve 36, a damping chamber 63 formed between the damper member 62 and the needle valve 36, a leak passage 64 for extracting and leaking out the fuel in the damping chamber 63, and a stopper member 41 to restrict the lift position of the damper member 62. Damping of the lift of the needle valve 36 is carried out by extracting and leaking out the fuel in the damping chamber 63 through the leak passage 64. The needle valve 36 functions as a guide for the damper member 62, and prevents vibration of the damper member 62, allowing a consistently stable damping effect to be obtained.
