Abstract

The dual temperature sensor for an engine includes a first sensor configured for detecting the temperature of an engine and for generating at least one information signal corresponding to the detected temperature of the engine, and a second sensor configured for detecting the temperature of the engine coolant and for generating at least one information signal corresponding to the detected temperature of the engine coolant within the engine. An insulator is positioned between the first sensor and the second sensor. The dual temperature sensor is mounted in the thermostat housing such that the first sensor of the dual temperature sensor is positioned outside the thermostat housing wall so that the first sensor is in communicating relation with the engine and the second sensor of the dual temperature sensor is positioned inside the thermostat housing in communicating relation with the engine coolant.

Claims
