摘要： An oxygen sensor is disposed upstream of a three-way catalyst in an exhaust system of an internal combustion engine and includes a sensing element of metal oxide whose electromotive force or resistance value varies in response to the concentration of oxygen in the engine exhaust gases. A catalytic body including a catalytic metal material exhibiting the same catalytic performance as that of the three-way catalyst is disposed around the sensing element or upstream of the oxygen sensor or is formed by impregnating a portion of the sensing element with the catalytic metal material, so that the air-fuel ratio at the intake side or exhaust side of the engine can be controlled depending on the output of the oxygen sensor.
