wherein the detected temperature of the engine by the first sensor is detected by sensing the temperature adjacent to an external wall of the engine;
a second sensor configured for detecting the temperature of an engine coolant and for generating at least one information signal corresponding to the detected temperature of the engine coolant;
an insulator positioned between the first sensor and the second sensor;
a housing containing the first sensor, the second sensor, and the insulator;
wherein the first sensor, the insulator, and the second sensor are axially aligned along an insertion direction of the housing;
a plurality of electrical delivery ports configured for receiving electricity from a power source, the electrical delivery ports being connected to the first sensor and the second sensor;
a plurality of electrical terminals connected to the first and second sensors, the terminals being adapted for communicating the first and second sensors to an engine controller through wiring; and
a threaded fitting disposed between the first sensor and the second sensor, the fitting being adapted for mounting in a thermostat housing of the engine with the first sensor extending external to the thermostat housing and the second sensor extending into the thermostat housing.

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.
