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 1):
An exhaust system of an internal combustion engine comprising:\n an exhaust member that constitutes a part of an exhaust passage through which exhaust gas of a multi-cylinder internal combustion engine flows, the multi-cylinder internal combustion engine including a first cylinder group and a second cylinder group; and an exhaust gas sensor that is provided in the exhaust member, wherein: the exhaust member includes\n a first collecting exhaust pipe comprising a first passage through which exhaust gas from combustion chambers of the first cylinder group of the internal combustion engine flows, \n a second collecting exhaust pipe comprising a second passage through which exhaust gas from combustion chambers of the second cylinder group of the internal combustion engine flows, and \n a junction exhaust pipe comprising a junction passage merging the exhaust gas flowing through the first passage and the exhaust gas flowing through the second passage; \n the first passage and the second passage are arranged side-by-side, wherein an inner wall constituting the junction passage includes a first continuous inner wall that continues into an inner wall of the first passage and a second continuous inner wall that continues into an inner wall of said second passage, the exhaust gas sensor is provided in the first continuous inner wall in such a manner as to protrude from the first continuous inner wall toward the center of the junction passage, and the first continuous inner wall includes a guide part that protrudes toward the center of the junction passage when viewed in a longitudinal section including the first passage, the second passage, the junction passage, and the exhaust gas sensor, the guide part being provided on the upstream side of the exhaust gas sensor.
