IN-CYLINDER PRESSURE MEASUREMENT UTILIZING A MAGNETO-ELASTIC ELEMENT FOR MEASURING A FORCE EXERTED ON AN ENGINE VALVE ASSEMBLY

A force sensor can include a magnetic field generator, a magnetic flux return, and a magneto-elastic layer. The magnetic flux return can extend along a first portion of at least one pathway of magnetic flux generated by the magnetic field generator. The magneto-elastic layer can be operable to be in...

Zusammenfassung:A force sensor can include a magnetic field generator, a magnetic flux return, and a magneto-elastic layer. The magnetic flux return can extend along a first portion of at least one pathway of magnetic flux generated by the magnetic field generator. The magneto-elastic layer can be operable to be in contact with a surface subjected to force and thereby strained. The magneto-elastic layer can extend along a second portion of the at least one pathway of magnetic flux distinct from the first portion.
