ABSTRACT:
An internal combustion engine system is disclosed which includes an engine crankshaft with a plurality of crankshaft webs. A reference ring is mounted to one of the crankshaft webs to rotate therewith. The ring encircles the crankshaft and has a number of angularly spaced indicators. A sensor is located proximate to the ring and detects the indicators to provide a sensor signal corresponding to a rotational characteristic of the crankshaft. The ring may be comprised of more than one piece to facilitate installation and removal without disassembly of the crankshaft. The indicators may be provided by defining a number of peripheral teeth for detection by the sensor.
