Zusammenfassung:	An internal combustion engine includes a cam shifting system having a shifting unit rotatably fixed and axially moveable with respect to a camshaft. The shifting unit includes at least two cams configured to be selectively brought in contact with a cam follower and provided with a base circle and with at least one cam lobe. The shifting unit is provided with at least one groove having a shifting portion. A driving pin is operable to be selectively engaged with and disengaged from the shifting portion of the groove. Engagement between the driving pin and the shifting portion of the groove moves the shifting unit with respect to the camshaft. During the movement of the shifting unit the cam follower engages at least a portion of at least one cam lobe.
