Abstract: 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.

Abstract: 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.

Abstract: A valve train layout for an overhead valve engine uses a single camshaft actuating two inlet valves and a single exhaust valve. The two inlet valves are preferably aligned on an inner side of a cylinder with the exhaust valve on an outer side. The inlet valves are preferably actuated by a cam follower and single push rod driving a rocker arm with dual arms and separate lash adjusters actuating the inlet valves. The exhaust valve is preferably actuated by a cam follower with a lash adjuster driving a single push rod operating a primary rocker arm that drives a secondary push rod pivoting an exhaust rocker arm to actuate the exhaust valve. In one embodiment, the primary rocker arm for the exhaust valve pivots on a common axis with the intake rocker arm. In an alternative embodiment, the primary rocker arm pivots on a canted pivot axis.

Abstract: 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.
