Axial cam shifting valve assembly with additional discrete valve event

A valve train assembly comprising:

• a rocker arm assembly;
• and
• an axial shifting cam assembly 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 configured to each selectively engage the rocker arm assembly to respectively perform a first and a second discrete valve lift event,
• wherein the rocker arm assembly is configured to perform a third discrete valve lift event, distinct from the first and second valve lift events.

An internal combustion engine, comprising:

• an engine valve configured to selectively open and close an exhaust or intake passage;
• a rocker arm assembly engaged with the engine valve at a first end;
• and
• an axial shifting cam assembly 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 configured to each selectively engage the rocker arm assembly to respectively perform a first and a second discrete valve lift event,
• wherein the rocker arm assembly is configured to perform a third discrete valve lift event, distinct from the first and second valve lift events.
