摘要： 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.

摘要： A method is disclosed for controlling compression-braking performance of an engine having a piston in a combustion cylinder. The method may include providing a valve in fluid communication with the combustion cylinder and at least one valve actuator operable to control the valve to perform compression-braking by opening the valve, which may include opening the valve to a first peak-valve-opening during a compression stroke of the piston and opening the valve to a second peak-valve-opening before a second half of an expansion stroke of the piston. The method may also include determining a target value for a stress in the at least one valve actuator. Additionally, the method may include designing the magnitude and timing of the first peak-valve-opening as a function of the target for the stress in the at least one valve actuator.
