摘要： A pump includes a housing defining an internal chamber having an axial inlet passage, a generally radial passage with an outlet to a volute. A rotatable impeller, disposed within the chamber, has a conical rear shroud sloping away from the axial inlet to define a rear recess. A shaft seal is disposed within the recess to minimize the axial length of the pump. A front surface of the shroud carries vanes operable to impel fluid from the axial inlet passage to the volute. Portions of the vanes extend forward into the axial inlet passage to induce coolant pre-rotation in the inlet passage and to improve pump efficiency. Pump efficiency may be further increased by a conical wall defining the axial inlet passage, a sloped wall defining the radial passage and a large radius between the axial inlet and the sloped wall to smooth fluid flow between the axial inlet passage and the volute.

摘要： Cam lobe packs and methods of producing the same. The method uses a tool made up of an insert disposed within a sleeve such that both are responsive to a dynamic magnetic compaction (DMC) pressure source. The insert defines a substantially axisymmetric exterior surface and a cam lobe-shaped interior surface that can receive a compactable material such that upon DMC, the material is formed into the shape of the cam lobe. The sleeve is disposed about the insert and defines a substantially axisymmetric exterior surface such that an axisymmetric compaction imparted to the sleeve by the DMC pressure source forms the desired shaped cam lobe. The tool is configured such that individual tool members corresponding to one or more of the cam lobes can be axially aligned so that an aggregate interior surface is formed that defines an exterior surface profile of a camshaft being formed.

摘要： An oil lubrication and control system, for an engine having cylinder deactivation switching lifters operated at the pressure of the full oil system, is provided with an auxiliary pressure relief valve which opens to control maximum oil pressure in the system whenever the engine speed and temperature conditions lie beyond the ability of the oil pump pressure control unit to maintain the maximum pressure limit. Addition of the auxiliary pressure relief valve allows extended operation of the switching lifters, which are limited by their construction to operation below a prescribed pressure limit. In a preferred embodiment, the auxiliary pressure relief valve is mounted in the engine crankcase in a bore connected directly with the main oil gallery to provide mounting and actuation of the auxiliary pressure relief valve with a minimum of modifications to the engine oil system design.

摘要： An engine valve train has oil flow to valve actuating components cut off or restricted when the valves are closed, to reduce parasitic losses. In an exemplary embodiment, a pushrod has a pivotable connection with a valve actuating rocker arm through which internal oil passages conduct oil for lubricating the rocker arm. The passages are aligned during valve actuation but become misaligned when the valve is closed. Misalignment of the passages at the sliding connection reduces the amount of oil flow through the connection to improve engine efficiency. When applied to cylinder deactivation engines, oil flow to rocker arms of deactivated valves is completely cut off, or reduced, further reducing parasitic losses.
摘要翻译：发动机气门机构在阀关闭时切断或限制阀致动部件的油流，以减少寄生损耗。在示例性实施例中，推杆具有与阀致动摇臂的可枢转连接，内部油通道通过该导向油导入油以润滑摇臂。通道在阀门致动期间对准，但当阀门关闭时会变得不对齐。在滑动连接处的通道的不对准减少了通过连接的油流量，以提高发动机效率。当应用于气缸停用发动机时，流入停用阀的摇臂的油被完全切断或减少，进一步减少了寄生损失。

摘要： A hydraulic control system to provide an oil or pressurized fluid supply to a variable cam phasing system in an engine is provided. The hydraulic control system includes a valve housing attachable to a front cover assembly of the engine; a first valve installed in the housing; and an inlet passage defined by the front cover assembly hydraulically communicating with the first valve in the housing to carry pressurized fluid from a fluid source to the first valve. A first and a second outlet passage defined by the housing hydraulically communicates with the first valve to allow the pressurized fluid to flow to the cam phasing system, thereby variably moving a camshaft assembly operatively connected to the cam phasing system.

摘要： An automotive engine component and method of producing the same. The method uses dynamic magnetic compaction to form components with non-axisymmetric and related irregular shapes. A die is used that has an interior profile that is substantially similar to the non-axisymmetric exterior of the component to be formed such that first and second materials can be placed into the die prior to compaction. The first material is in powder form and can be placed in the die to make up a first portion of the component being formed, while a second material can be placed in the die to make up a second portion of the component. The second material, which may possess different tribological properties from those of the first material, can be arranged in the die so that upon formation, at least a portion of the component's non-axisymmetric exterior profile is shaped by or includes the second material.
