Abstract
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.
