Abstract
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.
