Abstract
A gasket structure for supporting thermocouple junctions in a stream of gas passing through an internal combustion engine. The thermocouple leads are passed edgewise through a gasket, which is adapted to fit between the ports of an engine and the manifold associated therewith. The leads are firmly supported within the gasket, the junction formed by the ends thereof protruding into the gasket aperture. The thermocouple junction is thus disposed in the gas stream at a regular, predetermined distance from the combustion chamber of the engine. In one embodiment a plurality of thermocouples are embedded in an exhaust manifold gasket, each being associated with a separate exhaust port of an engine. A selector switch may be used to monitor the status of the gas flow through each port; or the thermocouples may be connected together so that an averaged signal is produced, and the signal utilized to monitor the fuel-air mixture ratio.
