Exhaust sensor mounting structure for cylinder head

Exhaust gas sensor mounting structure on cylinder head of internal combustion engine. Purpose: To provide an exhaust gas sensor mounting structure such that an exhaust gas sensor is mounted on a cylinder head of an internal combustion engine in the state where the exhaust gas sensor is protected. Solution media: In a cylinder head (41) of an internal combustion engine (6) having intake and exhaust valves (56 and 57) arranged in a "V" shape, where the exhaust ports (55) are they curve from the shafts of the respective exhaust valves (57) in a direction opposite to the intake valves (56), and a mounting flange surface for an exhaust element is formed at the downstream end of the exhaust ports. exhaust (55); an exhaust gas sensor is located on the periphery of the mounting flange surface such that it protrudes from the outer side surface of the exhaust ports (55) in the state where the exhaust gas sensor is tilted with respect to the axis of a cylinder.
