ABSTRACT:
In one aspect, the present disclosure is directed to an internal combustion engine having an engine block defining at least one cylinder and a head connected with said engine block. The head has an air intake port and an exhaust port. The internal combustion engine also has a piston and a combustion chamber. The internal combustion engine further has an air intake valve movable to open and close the air intake port and an air supply system having at least one turbocharger fluidly connected to the air intake port. The internal combustion engine additionally has a fuel supply system operable to inject fuel into the combustion chamber, a cam assembly selectively mechanically linked to the air intake valve to move the air intake valve, and an electromagnetic actuator configured to decouple the cam assembly from the air intake valve and control movement of the air intake valve.
