Abstract:
An exhaust system includes a turbine housing and an air-fuel ratio sensor. The turbine housing includes a first collecting exhaust pipe including a first passage, a second collecting exhaust pipe including a second passage, and a junction exhaust pipe including a junction passage. The first passage and the second passage are arranged in parallel. When an inner wall forming the junction passage is defined into a first continuous inner wall and a second continuous inner wall, the air-fuel ratio sensor is provided in the first continuous inner wall so as to protrude toward the center of the junction passage. A guide portion that protrudes toward the center of the junction passage is provided in the first continuous inner wall on the upstream side of the air-fuel ratio sensor.

Claim (Index 2):
The exhaust system of an internal combustion engine according to  claim 1 , wherein:\n the guide part includes a protruding peak, a face of the guide part on the upstream side of the protruding peak of the guide part is an inclined surface inclined toward the center of the junction passage from the upstream side to the downstream side, and when a virtual extended surface is obtained by extending the inclined surface to the downstream side from the protruding peak, when viewed in the longitudinal section, the virtual extended surface passes through an area closer to the second continuous inner wall than a detection part of the exhaust gas sensor.
