Valve train assembly

A type II valve train assembly that selectively opens first and second exhaust valves, the valve train assembly comprising:

• an exhaust rocker arm assembly, comprising:
• a first exhaust rocker arm configured to selectively open the first exhaust valve, a second exhaust rocker arm configured to selectively open the second exhaust valve, and an engine brake exhaust rocker arm configured to selectively and collectively open both of the first and second exhaust valves;
• a first exhaust HLA associated with the first exhaust valve, and a second exhaust HLA associated with the second exhaust valve;
• and
• an exhaust actuation assembly configured to selectively actuate to alter travel of the first and second exhaust HLA's to change a state of cylinder deactivation between activated and deactivated,
• wherein the valve train assembly is configurable for operation in any combination of activated and deactivated states of engine braking and cylinder deactivation.

A type II valve train assembly that selectively opens first and second intake valves and first and second exhaust valves, the valve train assembly comprising:

• an intake rocker arm assembly, comprising:
• an intake rocker arm configured to selectively open the first and second intake valves;
• an intake hydraulic lash adjuster (HLA) associated with the first intake rocker arm;
• and
• an intake actuation assembly configured to selectively actuate to alter travel of the intake HLA to change a state of cylinder deactivation between activated and deactivated;
• and
• an exhaust rocker arm assembly, comprising:
• a first exhaust rocker arm configured to selectively open the first and second exhaust valves;
• a second exhaust rocker arm configured to selectively open at least one of the first and second exhaust valves during engine braking;
• an exhaust HLA associated with the first exhaust rocker arm;
• an exhaust actuation assembly configured to selectively actuate to alter travel of the exhaust HLA to change a state of cylinder deactivation between activated and deactivated,
• wherein the valve train assembly is configurable for operation in any combination of activated and deactivated states of engine braking and cylinder deactivation.
