    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 of operating an internal combustion engine is provided. The method includes injecting a first fuel charge into at least one cylinder of the engine. The method further includes determining a value indicative of at least one of a cylinder pressure and a rate of change in cylinder pressure. The method further includes injecting a second fuel charge into the at least one cylinder, upon the occurrence of a predetermined contingency, which may be a determined cylinder pressure or rate in change thereof exceeding a predetermined threshold. An internal combustion engine is further provided, including an electronic controller having a control algorithm. The control algorithm includes software for determining a value indicative of at least one of a cylinder pressure and a rate of change in cylinder pressure of at least one cylinder of the engine. The control algorithm further includes logic for transitioning a fuel injector of the engine between modes, based upon the occurrence of a predetermined contingency, which may be the determined value.
