摘要： An injector is provided which includes a nozzle valve element, a control volume, and an injection control valve including a control valve member for controlling fuel flow from the control volume so as to control nozzle valve movement. Importantly, the injector includes a nozzle valve lift detecting device for detecting nozzle valve lift and providing a nozzle valve element lift feedback signal. Feedback signals are improved and control valve member oscillations are minimized by positioning a valve seat associated with the control valve member a spaced distance from the control volume, positioning a drain orifice such that the nozzle valve element restricts flow through a drain circuit when in an open position and extending the control valve member from the valve seat to the control volume to form an end wall of the control volume.

摘要： An piezoelectric actuated injector is provided which includes a nozzle valve element, a control volume, and an injection control valve including a control valve member for controlling fuel flow from the control volume so as to control nozzle valve movement. Importantly, the injector includes a preload chamber positioned along an injection control valve member for receiving high pressure fuel. The high pressure fuel acts on the injection control valve member to apply a preload force to supply a preload force to the stack of piezoelectric elements thereby ensuring more accurate control over fuel injection timing and metering.

摘要： The present invention relates to a system and method for managing the operation of a turbocharger and is responsible for controlling the turbocharger to cause a desired air mass flow to be provided to the engine and for protecting the turbocharger from excessive shaft speed and excessive turbine inlet temperature. The protection modes have higher priority than the performance control. First, turbocharger shaft speed is checked against a programmable limit, and the turbocharger is adjusted to bring the speed under control if its speed exceeds this limit. If the speed is not above the limit, the turbine inlet temperature is checked against a second programmable limit. If the turbocharger inlet temperature is above the predetermined limit, the turbocharger is adjusted to bring the inlet temperature under control. If, after either of these adjustments are made, the predetermined limits are still exceeded by the turbocharger, then the system invokes a derating of the fueling to the engine in order to protect the turbocharger. If none of the limits have been exceeded, then the system operates the turbocharger to provide the desired air mass flow to the engine in order to maximize engine performance.
摘要翻译： 本发明涉及一种用于管理涡轮增压器的操作的系统和方法，并且负责控制涡轮增压器以使发动机提供所需的空气质量流量并保护涡轮增压器免受过大的轴速度和过大的涡轮机入口温度 。 保护模式的优先级高于性能控制。 首先，根据可编程限制检查涡轮增压器轴速度，并且如果涡轮增压器的速度超过该限制，则调节涡轮增压器以使速度得到控制。 如果速度不超过极限，则涡轮机入口温度将针对第二可编程限制进行检查。 如果涡轮增压器入口温度高于预定极限，则调节涡轮增压器以使入口温度得到控制。 如果在进行这些调整之一之后，涡轮增压器仍然超过预定限制，则系统调用对发动机的加油降额以保护涡轮增压器。 如果没有超过限制，则系统操作涡轮增压器以向发动机提供期望的空气质量流，以便最大限度地发动机性能。

摘要： A system for diagnosing operation of a delta pressure sensor used with an internal combustion engine comprises an intake manifold and an exhaust manifold each operatively coupled to the engine, an EGR conduit fluidly coupled between the intake and exhaust manifolds, and a flow restriction mechanism disposed in-line with the EGR conduit, wherein the delta pressure sensor produces a delta pressure signal indicative of a pressure differential across the flow restriction mechanism. A control computer compares the delta pressure signal to a modeled delta pressure value modeled as a function of at least engine speed and one of engine load and engine output torque percentage, and diagnoses a fault state of the delta pressure sensor based on the comparison.

摘要： A method for automatically resuming vehicle speed control after a gear change of the vehicle's manual transmission. The method may be implemented as a subroutine in the vehicle's general control software. After disengagement of the clutch, the subroutine suspends the automatic speed control system and then periodically checks to determine if the driver has shifted gears within a predetermined time period. This determination is made by checking to see if the clutch has once again been engaged with the transmission in gear. If this occurs within the predetermined time period, then the control system automatically resumes the speed control of the engine. The determination of whether the transmission has been placed into another gear is made by an examination of calculated gear ratios, rather than by the addition of a hardware sensor.
