Abstract: An engine includes a block containing multiple valves, and a camshaft defining multiple cams for rotation about a camshaft axis. A valve lift assembly is operatively associated with a respective one of the cams and a respective one of the valves to transfer motion from the cam to the valve by reciprocal motion of the valve lift assembly along a lift axis. The assembly includes a follower and a follower control mechanism. The follower is disposed in contact with the cam at a contact point that defines a contact path extending along a surface of the cam as the cam rotates about the camshaft axis. The follower is moveable through an adjustment range to change the position of the contact point along the contact path at a given angular position of the cam. The follower control mechanism is operable to control the movement of the follower within the adjustment range.

Abstract: A turbine assembly is provided. The turbine assembly includes a turbocharger drive having a first threaded portion and a turbine wheel assembly. The turbine wheel assembly includes a turbine wheel and a second threaded portion adapted to engage the first threaded portion of the turbocharger drive. The turbine assembly may be utilized in a turbocharger assembly, wherein a compressor is connected to a second end of the turbocharger drive.
