  • Sensing rotation of an engine component relative to an engine body using a starter ring
    Patent number: 7469575
    Abstract: In one embodiment, a sensing apparatus senses rotation of an engine component (e.g., a crank shaft) relative to an engine body. The sensing apparatus includes a sensor, and a bracket configured to position the sensor in a fixed location relative to the engine body. The starter ring has (i) a support portion configured to rotate in tandem with the engine component, (ii) a starter interface mounted to the support portion, the starter interface being configured to receive drive from a starter motor during operation of the starter motor, and (iii) a trigger portion mounted to the support portion. The trigger portion is configured to provide a series of indicators during rotation of the engine component. The series of indicators (e.g., a series of magnetic field perturbations during rotation of the engine component) is readable by the sensor thus enabling identification of component positioning and speed.
