Kurbelwellenwinkelsensoranordnung und damit ausgerüsteter Motor

摘要

An internal combustion engine system 10 includes an engine crankshaft 60 with a plurality of crankshaft webs 70a-70f, 72a-72f. A reference ring 80 is mounted to one 72a of the crankshaft webs to rotate therewith. The ring 80 encircles the crankshaft 60 and has a number of angularly spaced indicators. A sensor 46 is located proximate to the ring 80 and detects the indicators to provide a sensor signal corresponding to a rotational characteristic of the crankshaft 60. The ring 80 may be comprised of more than one piece to facilitate installation and removal without disassembly of the crankshaft 60. The indicators may be provided by defining a number of peripheral teeth for detection by the sensor.
