Abstract
An integrated engine combustion monitoring system that includes at least one structure comprising a light communication channel (LCC) and a sensor, which are embedded in a cylinder head gasket, for monitoring combustion composition, pressure, or temperature. The sensor and the LCC may be positioned between an air cavity or a material comprising a photorefractive gel or polymer. The sensor includes a sensing component that may have various shapes or configurations. The LCC comprises one or more materials, such as a polymer, which may be formed into a strand or other structural shape and incorporated into the cylinder head gasket. The other end of the LCC may be fabricated as part of one or more engine structures or it may be connected to other structures or components such as optical detectors or associated process control electronics.
