。 A V-type engine in which the exhaust manifold of one bank of a pair of left and right banks is connected to the exhaust manifold of the other bank that communicates with the exhaust pipe via a communication pipe.
A catalytic converter for exhaust gas purification is provided in the exhaust system, and two oxygen concentration sensors, a first and a second oxygen concentration sensor, are provided upstream and downstream of the catalytic converter, and the air-fuel ratio is feedback-controlled by these two oxygen concentration sensors. In the fuel ratio control device, a first oxygen concentration sensor on the upstream side of the catalytic converter is arranged in the communication pipe, and a second oxygen concentration sensor on the downstream side of the catalytic converter is divided into two systems downstream of the catalytic converter. An air-fuel ratio control device for a V-type engine, characterized in that the device is disposed in one exhaust pipe.
