Abstract

A cylinder head of an internal combustion engine includes a first exhaust port section having an upstream inlet opened and closed by a first exhaust valve, a second exhaust port section having an upstream inlet opened and closed by a second exhaust valve, and a collective exhaust port section into which the first and second exhaust port sections merge at downstream ends thereof. In a fixing structure for an exhaust gas sensor, the sensor is fixed to the collective exhaust port section with its sensing tip in the port section. An exhaust gas guide part is formed, at a position upstream of the sensor, on an internal wall of the port section, opposite the internal wall to which the sensor is fixed, so as to bulge out to guide exhaust gas toward the sensor, whereby exhaust gas is effectively intermixed and directed to the sensor with resultant increased sensing accuracy.
