Abstract

PURPOSE:To secure detection for the CO concentration in the exhaust gas by forming the catalyst layer to one side of the substrate with the thermocouples provided on both sides to secure the heat generation through the contact to the exhaust gas and then detecting the differential thermal electromotive force caused by the temperature difference between the both thermocouples. CONSTITUTION:The heating element is buried at the middle part of substrate 1 of the gas sensor which detects the CO concentration in the exhaust gas of the diesel engine. At the same time, thermocouples 2a and 2b are provided on surface 1'a and back 1'b of substrate 1 each to be given the conduction on the side surface of substrate 1. The ceramic coating layer is formed on the surface of substrate 1, and catalyst 4 is held at coating layer 7b on thermocouple 2a to secure the reaction with CO. When the exhaust gas touches the sensor, the catalyst reaction is caused on surface 1'a of substrate 1 to give the heat generation. Accordingly, the temperature difference is caused between thermocouples 2a and 2b, and thus the differential thermal electromotive force is caused between output terminals 3a and 3b. Then the output is detected to secure detection for the CO concentration in the exhaust gas.
