摘要： Although injection timing accuracy is sensitive to rail pressure, injection quantity of the fuel injection event is strongly a function of rail pressure. Thus, delivery accuracy of each injection event depends strongly upon the accuracy of a rail pressure estimate used in determining the injection control signal characteristics. These injection control signal characteristics include a calculated delay between a start of control current and start of injection, as well as the duration of the control signal. The present invention takes a rail pressure measurement substantially before an injection event, and then utilizes a rail pressure predictor model to predict what the rail pressure will be at each injection event in a succeeding injection sequence. This estimated rail pressure is then used as the means for determining the fuel injection control signal characteristics for that succeeding injection event.
摘要翻译：虽然喷射定时精度对轨道压力敏感，但燃料喷射事件的喷射量强烈地是轨道压力的函数。因此，每个喷射事件的输送精度主要取决于在确定喷射控制信号特性时使用的轨道压力估计的精度。这些喷射控制信号特性包括控制电流开始和喷射开始之间的计算延迟以及控制信号的持续时间。本发明基本上在喷射事件之前进行轨道压力测量，然后利用轨道压力预测器模型来预测在随后的喷射序列中在每次喷射事件时轨道压力将是什么。然后将该估计的轨道压力用作确定后续喷射事件的燃料喷射控制信号特性的装置。

摘要： A method of controlling a hydraulic system is preferably applied to common rail fuel injection systems. The problem in these systems is to control pressure in the common rail while at the same time maintaining the fluid supply to the rail in a way that precisely meets the dynamically changing consumption demands on the hydraulic system. In order to control the hydraulic system, the present invention contemplates the combination of a standard feedback controller with observer models of the various hardware items that make up the hydraulic system. Using this strategy, the system can generally be thought of as controlling fluid supply in an open loop type fashion based upon the consumption rates estimated by the various observer models, and utilizing a conventional feedback controller to make the slight pump adjustments needed to control pressure and to correct for any errors between the actual hardware performance and that predicted by the observer models.

摘要： With reference to the drawings and in operation, the present invention is adapted to provide a method and apparatus for dynamically controlling the injection timing of a fuel injector connected to a fuel system located within an engine. The method includes the steps of establishing a desired injection timing of the injector 104 and determining an fuel injection command delivery time in response to the desired injection timing, and responsively delivering the fuel injection command. The actual injection timing is determined, and then the injection command delivery time is modified in response to comparing the actual and the desired injection timing. Comparing the actual and desired injection timing provides for closed loop control of the injection timing of the fuel system 102.

摘要： A method for controlling transfer from use of a first injection waveform type to use of a second injection waveform type in a hydraulically-actuated electronically-controlled fuel injection system of an engine includes sensing an engine speed and an engine load when the first injection waveform type is selected and storing the sensed engine speed and the sensed engine load. An actual engine speed is thereafter compared with the stored engine speed and an actual engine load is thereafter compared with the stored engine load. Transfer from use of the first injection waveform type to use of the second injection waveform type is prevented unless at least (i) a difference between the actual engine load and the stored engine load exceeds a predetermined load amount, or (ii) a difference between the actual engine speed and the stored engine speed exceeds a predetermined speed amount.

摘要： An apparatus is provided for controllably positioning a movable element within a hydraulic motor in response to a flow request signal. An electric circuit receives the flow request signal and responsively produces an energization signal. An electromagnetic actuator has a core, and a coil with a plurality of windings wound as a helix around the core. The coil is adapted to receive the energization signal and responsively produce a magnetic force proportional to the magnitude of the energization signal forcing the core to move bidirectionally relative to the coil. A mechanical coupling has one end connected to and movable with the core. A directional valve includes a spool connected to the other end of the mechanical coupling. The directional valve precisely meters pressurized fluid to the motor causing the movable element to move in response to the movement of the core.
