A valve train assembly configured to selectively open and close intake and exhaust valves associated with cylinders of an internal combustion engine comprises an intake rocker arm assembly, an intake cam assembly, a first axial shifting cam assembly and a second axial shifting cam assembly. The intake rocker arm assembly can have a plurality of intake rocker arms. The intake cam assembly can be associated with each of the cylinders and can have three distinct cam profiles including a first cam profile, a second cam profile and a third cam profile. The first axial shifting cam assembly can operate independently from the second axial shifting cam assembly to provide three distinct valve lift profiles on the first grouping of cylinders and three distinct valve lift profiles on the second grouping of cylinders.

A valve train assembly includes a rocker arm assembly, and axial shifting cam assembly, and a lost motion device. The axial shifting cam assembly is movable between a first axial position and a second axial position on a camshaft, the cam assembly having a first cam having a first lobe, and a second cam having a second lobe. The first and second lobes are configured to each selectively engage the rocker arm assembly to respectively perform a first and a second discrete valve lift event. The lost motion device is operably associated with the rocker arm assembly and configured to perform a third discrete valve lift event, distinct from the first and second valve lift events.

The present disclosure relates to dual compression engine boosting systems utilizing both a turbocharger and a supercharger and control systems relating to relative activation and deactivation of the boosting devices. Various Exhaust Gas Recirculation (EGR) configurations are also disclosed for the dual compression engine boosting systems.
