摘要： A strategy for quantifying and compensating for between-engine variations in engine static timing, fuel pump phasing and overall system bandwidth includes a control circuit operable to manage a fuel control system including a high pressure, cyclically operable fuel pump and at least one fuel injector operable to supply fuel to an internal combustion engine from a fuel collection unit. In one embodiment, the strategy of the present invention is operable to determine peak values of the fuel pressure within fuel collection unit and corresponding engine position values for a number of different engine speeds and solve a corresponding model-based system of equations to determine a combined engine static timing and fuel pump phasing error as well as a first overall system bandwidth value. In another embodiment, the strategy of the present invention is operable to determine peak values of the pressure within a combustion chamber of the engine along with associated engine position values for a number of different engine speeds and solve for the engine static timing error alone and/or a second overall system bandwidth value. In yet another embodiment, the two foregoing strategies may be combined to produce separately the first and second bandwidth values as well as the individual engine static timing and fuel pump phasing error values. In any case, the computed error and bandwidth values may be used to improve the accuracy of sampled engine and/or fuel control system parameters as they relate to engine position.

摘要： An improved closed nozzle injector assembly for injecting high pressure fuel into the combustion chamber of an engine is provided which includes a first needle valve element associated with a first set of injector orifices, a first needle valve control device for controlling the opening and closing of the first needle valve, a second needle valve associated with a second set of injector orifices and a second needle valve control device for controlling the opening and closing of the second needle valve. Each needle valve control device includes a control volume positioned at one end of the respective needle valve, a control volume charge circuit for supplying high pressure fuel to the respective control volume and the respective injection control valve for controlling the flow of high pressure fuel from the respective control volume to a low pressure drain thereby controlling the movement of the respective needle valve. Using a dedicated control volume and injection control valve for each needle valve element permits effective control over the duration of pilot and post fuel injection events while also providing variable rate shaping capability for optimized emissions and fuel economy. The present dual needle valve element injector includes various components such as biasing springs which are positioned and interconnected to other components in a manner which creates a simple, compact fuel injector package providing independent control of two sets of spray orifices in one injector.

摘要： A fuel control system for an internal combustion engine including injected fuel quantity estimation includes a fuel pump responsive to a fuel pump command to supply fuel to a fuel collection unit. A pressure sensor is provided for producing a pressure signal indicative of the pressure of fuel within the collection unit throughout a fuel injection event, and an engine position sensor is provided for producing an engine position signal indicative of a crank angle of the engine relative to a reference crank angle. A control circuit includes means responsive to the pressure signal and a desired fueling value for producing an initial fueling command, and further includes a fuel quantity estimation block responsive to the pressure signal, the engine position signal and a final fueling command to produce a fuel quantity estimation value. The final fueling command is computed by the control circuit as a function of the initial fueling command and the fuel quantity adjustment value to which the injector is responsive to supply fuel to the combustion chamber.

摘要： A fuel injector including a floating sleeve control chamber is provided which effectively minimizes friction and wear, and thus prevents stiction, of a nozzle valve element by avoiding the need to align two bore guiding surfaces for the element. The floating sleeve control chamber includes a floating sleeve positioned on a control piston formed integrally with a nozzle valve element and positioned in a cavity. The floating sleeve is sized with an outer extent or diameter sufficiently less than the size of a surrounding cavity wall so as to permit lateral movement of the floating sleeve and thus movement of the control chamber. Only the nozzle valve element guiding bore surfaces control the alignment of the nozzle valve element relative to its seat while the floating sleeve effectively forms and seals a floating control chamber. The floating sleeve may be formed from one or more sleeve sections. In addition, the floating sleeve may include one or more swivel joints to accommodate perpendicularity errors between the components.

摘要： The improved solenoid actuator assembly of the present invention includes a solenoid stator assembly positioned in an actuator housing and a flux dissipation reducing feature which minimizes flux leakage into the housing thereby maximizing the attractive force and minimizing the response time. The flux dissipation reducing feature includes a slot formed in the housing adjacent each outer face of the solenoid stator pole pieces thereby avoiding a metallic housing wall into which leakage may occur. The slots also permit the cross sectional area of the pole pieces to be maximized thereby increasing the available attractive force. The solenoid stator assembly requires only a single housing which functions to directly support the laminate stack assembly without an intermediate housing while also functioning as an injector body component subject to the compressive assembly load of the injector and including high pressure fuel passages. As a result, the present solenoid actuator assembly is compact, inexpensive and functions to optimally maximize attractive forces while reducing response time.
摘要翻译：本发明的改进的螺线管致动器组件包括定位在致动器壳体中的螺线管定子组件和磁通耗散减少特征，其最小化到壳体中的通量泄漏，从而使吸引力最大化并使响应时间最小化。磁通耗散减小特征包括邻近螺线管定子极片的每个外表面处形成在壳体中的槽，从而避免可能发生泄漏的金属壳体壁。狭槽还允许极片的横截面面积最大化，从而增加可用的吸引力。螺线管定子组件仅需要单个壳体，其功能是直接支撑层压叠层组件而没有中间壳体，同时还用作经受喷射器的压缩组件载荷并包括高压燃料通道的喷射器主体部件。因此，本螺线管致动器组件是紧凑的，便宜的，并且在减少响应时间的作用下最佳地最大化吸引力。

摘要： A closed nozzle fuel injector is provided which effectively controls the fuel injection flow rate, especially during an initial portion of an injection event, while also permitting accurate control over pilot and/or post injection flow rates at all operating conditions thereby advantageously reducing emissions and combustion noise. The injector includes a rate shaping orifice to restrict fuel flow during an initial portion of an injection event and a rate shaping sleeve mounted for movement to cause a greater flow of injection fuel during a later portion of the injection event. A damping chamber and orifice are also provided to control movement of the rate shaping sleeve.

摘要： A high pressure control valve according to the present invention provides effective and predictable control of a timing fluid and injection fuel metering system of an internal combustion engine. The control valve includes an armature that abuts against a majority of the surface of a valve element to help minimize beating problems. In addition, a compliant web means provides a flexing motion when the valve element seats with a valve seat to mitigate problems of seat beating. Furthermore, the present invention reduces the number of parts of the control valve to achieve simplicity in structure and lower costs, including eliminating the need for a valve stop pin.

摘要： A fluid control device for use in a high pressure fluid system, the device including a device body with a cavity and a high pressure circuit, a plunger positioned for reciprocal movement in the cavity, and a leakage reduction cap mounted to the plunger for reducing fluid leakage flow. In one implementation, the leakage reduction cap includes a flexible portion positioned between the device body and the plunger, and defining an annular clearance gap between the leakage reduction cap and the device body. The flexible portion of the leakage reduction cap resiliently flexes radially outwardly in response to fluid pressure forces to reduce the annular clearance gap so as to minimize fluid leakage flow through the annular clearance gap.
