Abstract
The present disclosure relates to an internal combustion engine system including an internal combustion engine comprising a cylinder; an air guide arranged to guide air to the cylinder; at least one inlet valve adapted to selectively provide a fluid communication between said air guide and said cylinder; and an inlet valve actuation assembly for actuating said at least one inlet valve, said inlet valve actuation assembly being adapted to actuate said at least one inlet valve in accordance with one of at least two lift modes during a combustion cycle of said internal combustion engine. The internal combustion engine system is adapted to be operated in a first operation mode in which said throttle arrangement is arranged in an at least partially closed condition and said inlet valve actuation assembly actuates said at least one inlet valve according to a second of the at least two lift modes.
