Abstract

An engine assembly may include an engine structure, a camshaft, a timing wheel and a camshaft position sensor. The camshaft may be rotationally supported within the engine structure and may have a non-magnetic journal rotationally fixed thereto. The timing wheel may be rotationally fixed to the camshaft proximate the non-magnetic journal. The camshaft position sensor may be coupled to the engine structure and configured to determine the rotational position of the camshaft based on a magnetic impulse from the timing wheel.
