摘要： A camshaft damping mechanism may include first and second housing members and a biasing member. The first housing member may be engaged with a camshaft. The second housing member may be slidably coupled to the first housing member and may abut an engine structure. The biasing member may be retained axially between the first and second housing members and may force the first housing member in an outward axial direction from the second housing member.

摘要： A hydraulically lashed end pivot rocker arm assembly finds application in high performance valve trains of internal combustion engines. The rocker arm is mounted at one end upon an eccentric bearing assembly and includes a surface for engaging a valve stem at the opposite end and a roller engaged by a camshaft disposed between the ends. The eccentric bearing assembly includes a stub shaft or cylindrical body that is received within a bore in the rocker arm and an eccentric bore which receives an inner shaft which extends along the cylinder head and supports the eccentric bearings and the rocker arm assemblies. The stub shaft or cylindrical body includes an ear or lug which is engaged by a hydraulic lash adjuster disposed parallel to and offset from the vertical plane of motion of the rocker arm.

摘要： An engine assembly may define first and second combustion chamber and may include a camshaft having a first lobe region engaged with the first valve arrangement and a second lobe region engaged with the second valve arrangement and rotatable relative to the first lobe region. The cam phaser may be coupled to the camshaft and may include a first member and a second member rotatable relative to the first member. The first lobe region may be fixed for rotation with the first member and the second lobe region may be fixed for rotation with the second member to vary valve timing for the second combustion chamber independently from the valve timing of the first combustion chamber.

摘要： A system includes a fuel cutoff module and a cylinder deactivation module. The fuel cutoff module generates a fuel cutoff signal when a deceleration fuel cutoff condition occurs, wherein fueling to M cylinders of an engine is disabled based on the fuel cutoff signal, and wherein M is an integer greater than or equal to one. The cylinder deactivation module deactivates the M cylinders in response to the fuel cutoff signal.
