An internal combustion engine includes a cylinder block, a cylinder head and a cylinder head cover module attached to the cylinder head. The cylinder head cover module includes passageways and a plurality of receiving features for valve train components. A housing may be integrally formed with the cylinder head cover module. The cylinder head cover module may include components of a non-integrated valve control system and may be used in either an inline or a V-shaped engine.

Cylinder head cover module with integrated valve train

A cylinder head assembly for an internal combustion engine includes a fluid cavity that contains a fluid. The cylinder head assembly also includes a first member with a first internal surface defining a first part of the fluid cavity. Also, the assembly includes a second member with a second internal surface defining a second part of the fluid cavity. The second member is coupled to the first member. The first and second internal surfaces cooperate to define the fluid cavity.

Cylinder head assembly and method of forming the same

A variable lift deactivateable valvetrain system for an engine is provided. The system includes a camshaft, a rocker shaft, a valve and at least one rocker arm rotateably connected to the rocker shaft and arranged to engage the camshaft. A connecting rocker arm is rotateably connected to the rocker shaft and is in constant engagement with the valve. The connecting rocker arm is arranged to operate in selective engagement with the at least one rocker arm to provide a variable lift deactivateable valvetrain configuration. The system further includes a low lift rocker arm having a low lift pin assembly and a high lift rocker arm having a high lift pin assembly. The low and high lift pin assemblies are arranged to selectively engage the connecting rocker arm responsive to oil pressure selectively directed to the low and high lift pin assemblies.

Valvetrain system for an engine

A rocker shaft arrangement for a valvetrain system of an engine is provided. The rocker shaft arrangement includes a split rocker shaft having two fluidly separate internal regions. Each of the fluidly separate internal regions is arranged to selectively carry an independent supply of pressurized oil for distribution to valvetrain components. The two fluidly separate regions of the split rocker shaft are each further arranged to supply pressurized oil independent of each other to one of a high lift rocker arm and a low lift rocker arm of a rocker arm assembly for an engine valvetrain system.
