Zusammenfassung:	A camshaft-drive tensioner system is disclosed for an internal combustion engine having a camshaft-drive element. The camshaft-drive tensioner system includes a tensioner configured to be energized by a pressurized fluid in order to apply a force to the camshaft-drive element. The camshaft-drive tensioner system also includes a fluid pump configured to supply the pressurized fluid. The camshaft-drive tensioner system additionally includes a controller configured to regulate either volume or pressure of the fluid supplied to the tensioner by the fluid pump to thereby selectively vary the force applied to the camshaft-drive element. An internal combustion engine having such a camshaft-drive tensioner system and a method of selectively varying a force applied to the camshaft-drive element are also disclosed.
