制御装置。In a multi-cylinder internal combustion engine, an oxygen sensor is attached to a dual manifold formed in the engine exhaust system, and feedback control is performed based on a signal from the sensor so that the air-fuel ratio is always at a predetermined value. In addition to installing it in the collective exhaust passage of one manifold,
An air-fuel ratio control device for a multi-cylinder internal combustion engine, characterized in that a communication hole is provided in a partition wall that partitions this collective exhaust passage from the collective exhaust passage of the other manifold, located near the oxygen sensor.
