Zusammenfassung:In a motor vehicle valve train adjustment device comprising at least one camshaft with at least two axially displaceable cam elements wherein at least one cam element has a cam track with a valve lift and a cam track with zero valve lift for a deactivation of at least one cylinder, and at least one other cam element of the at least two axially displaceable cam elements has a cam track with a first valve lift and a cam track with a second valve lift by which a cylinder which remains fueled during a partial cylinder deactivation is adapted to the at least one cylinder deactivation by special valve lift characteristics.
