ABSTRACT:
Apparatus senses the temperature in a cylinder of an internal combustion engine. The apparatus comprises a spark plug having a central electrode located on the axis of the spark plug, a ceramic insulator encircling the centrally located electrode, a metal casing encircling the ceramic insulator, and a second electrode extending from the metal casing to a position adjacent to the central electrode. The metal casing has continuous threads formed therein and encircling the metal casing for threaded engagement with corresponding threads of an internal combustion engine. A thermocouple is located within the outer periphery of the metal casing and extends to a position adjacent to the gap between the electrodes. The thermocouple has a temperature-sensing junction adjacent to the gap and which junction is located in the cylinder when the spark plug is threaded with the corresponding threads of the engine. A meter connected with the thermocouple indicates the temperature in the cylinder when the engine is operated.
