Abstract

A magnetic torque oscillation controller for a camshaft (102) comprises first and second magnetic arrays (120, 112) located upon the cylinder head (104) and camshaft (106) respectively. The first and second magnetic arrays (120, 112) are positioned relative to each such that a torque oscillation of the camshaft can be either increased or decreased, selectively.
