摘要： An oxygen concentration sensor (28) is disposed in an engine exhaust passageway. The alcohol concentration in the fuel used in the internal combustion engine is detected. A target impedance is set on the basis of the detected alcohol concentration. The actual impedance of a sensor element of the oxygen concentration sensor (28) is detected. The heater output of the exhaust gas sensor is controlled so that the actual impedance becomes equal to the target impedance, whereby the temperature of the sensor element represented by the impedance becomes equal to a target temperature represented by the target impedance.

摘要： Fuel reforming catalysts 28 generate a hydrogen-containing reformed gas when they come into contact with exhaust gas that contains a reforming fuel. Upstream and downstream air-fuel ratio sensors 58, 60 are respectively installed upstream and downstream of the fuel reforming catalysts 28. The upstream air-fuel ratio sensor 58 outputs a upstream sensor signal in accordance with oxygen concentration. The downstream air-fuel ratio sensor 60 outputs a downstream sensor signal in accordance with oxygen concentration and hydrogen concentration by using zirconia's oxygen detection capability and a change of a diffusion layer's hydrogen-concentration-dependent oxygen detection capability. An ECU 50 detects the hydrogen concentration without being affected by the oxygen concentration through the use of the upstream sensor signal in which only the oxygen concentration is reflected and the downstream sensor signal in which the oxygen concentration and hydrogen concentration are reflected. This makes it possible to establish a hydrogen concentration detection system with the common air-fuel ratio sensors 58, 60.
