Abstract:
An internal combustion engine with a camshaft drive apparatus having an integral timing target, comprising:a support structure for the camshaft and position sensor;said camshaft drive having a first end extending perpendicularly to said camshaft's axis of rotation;said first end defining an annular timing surface including a first arcuate region and a second arcuate region;said first arcuate region extending in an axial direction outwardly from said second arcuate region;a position sensor carried by said support structure and positioned adjacent to said first end; said first arcuate region being more closely spaced from said sensor than said second acuate region wherein said position sensor detects a difference in spacing from said first and second arcuate regions; andsaid camshaft drive having a second end defining a second end surface extending parallel to said timing surface on said first end, and wherein said second end has a first arcuate region formed outwardly in an axial direction with respect to said second end and said second arcuate region formed inwardly in an axial direction with respect to said first arcuate region.
