Abstract (en)
An internal combustion engine (1) comprises an oil pump (35), an oil line (22) being fluidly connected to the oil pump (35) and engine parts to be lubricated and a hydraulic actuator (18) including an actuator housing which accommodates a movable plunger (19) and an oil chamber (20). The plunger (19) is drivably coupled to an adjusting element (17) for adjusting an engine operating mode. The engine (1) is provided with a control system (CS) including a first control mode for moving the plunger (19) in a first direction (X), a second control mode for moving the plunger (19) in a second direction (Y) which is opposite to the first direction (X) and a third control mode for maintaining the plunger (19) at a fixed position within the actuator housing. The engine (1) is provided with a first passage (27) in the oil line (22) and a second passage (28) between the oil line (22) at an upstream side of the first passage (27) and the oil chamber (20). The first passage (27) is closable by the control system (CS), wherein the control system (CS) is configured such that under operating conditions in the first control mode the first passage (27) is closed such that the oil pump (35) communicates with the oil chamber (20) only.
