ABSTRACT:
Systems and methods for managing camshaft dynamic loads associated with actuation of a camshaft-driven auxiliary device in a multiple-cylinder internal combustion engine apply positive and negative torque to the camshaft in a phased relationship relative to actuation of the auxiliary device and optionally relative to actuation of intake or exhaust valves operated by the camshaft.
