多気筒内燃機関の空燃比制御装置。A multi-cylinder internal combustion engine in which an oxygen sensor is attached to a dual manifold or an octopus-like independent manifold formed in the engine exhaust system, and feedback control is performed to keep the air-fuel ratio always at a predetermined value based on the signal from the sensor. In the method, a bypass passage having a predetermined length is formed in each of the plurality of exhaust passages or a collective exhaust passage, and these bypass passages are gathered at an intermediate portion, while
This gathering part is an air-fuel ratio control device for a multi-cylinder internal combustion engine, which is equipped with an oxygen sensor.
