Device for operating an internal combustion (IC) engine has a casing to support a sensor element alongside a functional unit for operating engine

摘要

A sensor casing (20) has a sensor element (15) and fits between a functional unit (10) and a casing (5) for supporting the sensor casing in a device that acts as a spark plug, a heater plug, an intake valve, an exhaust valve or a fuel injection valve. The sensor element is embedded between upper (40) and lower (45) contact layers separated from the sensor casing by insulating layers (50,55).
