Abstract

A system and method for non-contact engine parameter sensing. A magnetized engine component establishes a magnetic field that varies in response to stress imparted within the engine. A magnetic field sensing element spaced from the magnetized engine component is configured to provide an output indicative of a state of combustion in response to the magnetic field.
