Abstract: Systems, apparatus, and methods are disclosed that include an internal combustion engine having a plurality of cylinders operable by a valve actuation mechanism with at least two non-zero valve lift profiles. The first non-zero valve lift profile operates the intake valve(s) of each cylinder in response to nominal operating conditions while the exhaust valves are also opened and closed, and the second non-zero valve lift profile operates the intake valve(s) of a portion of the plurality of cylinders in response to a cylinder deactivation condition while the exhaust valve(s) of the portion of the plurality of cylinders are closed.

Abstract: System and methods mount an accessory to an engine block having a pilot bore aligned with a first plane and sealing surfaces aligned to a second plane different than the first plane. The accessory includes a sliding pilot for interfacing with the pilot bore that is capable of sliding in an "x" direction yet fixed in a "y" direction with respect to the accessory housing. Interfacing the sliding pilot in a mounting position with the pilot bore along a "z" direction locates the accessory with respect to the engine block in the "y" and "z" directions. Fastening the accessory to the sealing surfaces of the engine block locates the accessory in the "x" direction with sufficient precision to mitigate gear backlashing and providing one or more fluid seals between the accessory and the engine block.

Abstract: A variable valve actuation system is disclosed. In one form a rocker is disclosed coupled with a valve stem at one end and a cam follower at the other end. The rocker is operable to rotate about a fixed axis. In one form the cam follower includes a set of lower rollers operable to follow one cam lobe and an upper roller operable to follow another cam lobe. A leaf spring can be used to couple the cam follower with the rocker. A cam shaft is disclosed having a nested configuration that includes an inner shaft, an intermediate tube, and an outer tube. Cam lobes can be fastened to the cam shaft in one form by fastening through each of the inner shaft, intermediate tube, and outer tube. In another form the cam lobes can be attached by at least two devices inserted from either side of the cam shaft and that are not inserted at least through the inner shaft.
