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 4):
The exhaust system of an internal combustion engine according to  claim 1 , wherein:\n the exhaust system further comprises an exhaust manifold including\n a first upstream, collecting exhaust pipeline that guides exhaust gas from the combustion chambers of the first cylinder group to a first exhaust gas inlet of the first collecting exhaust pipe, and \n a second upstream collecting exhaust pipeline that guides exhaust gas from the combustion chambers of the second cylinder group to a second exhaust gas inlet of the second collecting exhaust pipe; \n the first exhaust gas inlet and the second exhaust gas inlet are disposed along a predetermined overlapping direction; and the first upstream collecting exhaust pipeline curves larger in the overlapping direction than the second upstream collecting exhaust pipeline.
