Device and method to measure the angular position of the camshaft or the crankshaft of an internal combustion engine

摘要

Device for measuring the angular position of a combustion engine cam- or crankshaft, whereby the shaft has a fixed signaling wheel with a code track around its circumference in the form of teeth with at least a number of missing teeth or other marking features. The inventive device has a signaling wheel with an additional code track and two probes for sensing the signals generated by the tracks. An independent claim is made for a method for measuring the angular position of an engine cam- or crankshaft.
