Abstract: A camshaft assembly for a vehicle valvetrain having first and second engine valves includes a camshaft, and a first camshaft cartridge axially displaceable along the camshaft and including a plurality of first cam lobes configured to selectively impart movement to the first engine valve. A second camshaft cartridge is axially displaceable along the camshaft and includes a plurality of second cam lobes configured to selectively impart movement to the second engine valve. An actuator is configured to axially displace the first camshaft cartridge along the camshaft. A coupling is between the first camshaft cartridge and the second camshaft cartridge. Axial displacement of the first camshaft cartridge selectively imparts movement to the second camshaft cartridge for axial displacement of the second camshaft cartridge.

Abstract: An intake manifold assembly for a vehicle engine includes an intake manifold housing defining a main chamber having perimeter walls and an open upper end; a charge air cooler (CAC) positioned in the main chamber and having an upper cover plate defining a sealing flange; and an integrated positive crankcase ventilation (PCV) system. The PCV system includes a PCV chamber integrally formed into an upper surface of one of the perimeter walls, the PCV chamber having an open upper end; a PCV port integrally formed with the intake manifold housing and in fluid communication with the PCV chamber; a distribution port defined by a wall of the PCV chamber and in fluid communication with an outlet plenum of the intake manifold. Upon securing the CAC to the intake manifold housing, the CAC sealing flange provides a sealed closure for the intake manifold main chamber and the PCV chamber.
