空燃比制御を行う内燃機関において、複数個の０□セン
サを、機関本体に接続される排気通路の排気流れ方向に
対して異なる位置にそれぞれ装着すると共に、これら０
２センサからの各出力に基づいて最初に活性化した０２
センサを選択するセンサ選択手段を設け、選択した０２
センサの出力を空燃比制御用信号として使用する構成と
したことを特徴とする排気中酸素濃度検出装置。In an internal combustion engine that performs air-fuel ratio control based on the oxygen concentration in the exhaust gas detected by a 0° sensor, multiple 0□ sensors are installed at different positions in the exhaust passage connected to the engine body in the exhaust flow direction. At the same time as installing these 0
02 activated first based on each output from two sensors.
A sensor selection means for selecting a sensor is provided, and the selected 02
An exhaust oxygen concentration detecting device characterized in that the output of the sensor is used as an air-fuel ratio control signal.
