Abstract:

In an internal combustion engine, a shaft driving apparatus and timing assembly in the form of a camshaft sprocket having first and second ends extending perpendicular to the axis of rotation. The first end for defining an annular timing surface positioned adjacent an angular position sensor and including a first arcuate surface region extending outwardly in the axial direction from the sprocket's first end and a second surface arcuate region recessed in the axial direction with respect to the first arcuate surface region. As the camshaft rotates, the closeness of the position sensor to the first arcuate surface region and the relative greater distance of the sensor to the second arcuate surface region produces different effects so that the sensor can detect the camshaft's angular position.
