A gasket enclosed sensor system designed to facilitate measurement of combustion chamber parameters, and delivery of signals to a point external to the engine. In one embodiment, the system is adaptable to an internal combustion engine that includes an engine block having a cylinder bore forming a cylinder, a piston free to reciprocate within the cylinder, and a cylinder head mating with the engine block to define a combustion chamber for the cylinder. A gasket extends from the combustion chamber to a point external to the engine, the gasket substantially surrounding the combustion chamber, and including an access opening extending from the combustion chamber to a point external to the engine. A metallic sensor terminal is positioned within the access opening in the gasket, with an insulating material substantially surrounding the metallic sensor terminal. In other embodiments of the invention, various types of sensors and signal pathways are provided.

A sensor system for an internal combustion engine having an engine block, a cylinder bore therein forming a cylinder, and a piston free to reciprocate within the cylinder bore, and including a cylinder head that mates with the engine block to define a combustion chamber for the cylinder, the sensor system comprising: an annular support structure substantially enclosing an array of sensors such that the sensors are disposed around, and in proximity to, the combustion chamber; a gasket, interposed between the cylinder head and the engine block, and displaced laterally away from the annular support structure, generally surrounding the array of sensors, and extending from approximately adjacent the outer edge of the annular support structure to a point external to the engine to seal the combustion chamber and the support structure from points external to the engine, and providing a network of discrete plural signal pathways from the sensor array to a point external to the engine.
