Abstract
An exhaust manifold for an internal combustion engine wherein exhaust ducts connected to respective engine cylinders are formed of discrete pipe members. A united section has an upstream divergent portion connected to the exhaust ducts and a downstream convergent portion to exhaust pipes. An internal space is defined in the downstream convergent portion and located intermediately between adjacent internal passages in the downstream convergent portion to communicate them with each other. An opening is formed in the peripheral wall of the downstream convergent portion at a location positionally corresponding to the internal space. A flange member has a boss formed thereon and being larger in size than the opening and disposed in face-to-face contact with an outer surface of the peripheral wall of the downstream convergent portion. The boss has a through bore formed therein and aligned with the opening, through which an exhaust constituent concentration sensor is to be inserted.
