Abstract (en)
An exhaust manifold (2) includes a head flange member (20), a plurality of branch pipe parts (3a-3d) and a collector pipe part (3e). The head flange member (20) has a flange main body portion (2a) and a cylinder head (1a) mounting surface configured and arranged to be attached to a cylinder head (1a) of an engine (1). Each of the branch pipe parts (3a-3d) has an upstream end portion with respect to an exhaust gas flow fixed to one side of the head flange member (20) that is opposite from the cylinder head (1a) mounting surface. The collector pipe part (3e) is connected to a downstream end portion with respect to the exhaust gas flow of each of the branch pipe parts (3a-3d). An area of the cylinder head (1a) mounting surface is smaller than a cross sectional area of the head flange main body portion (2a) taken along a plane substantially parallel to the cylinder head (1a) mounting surface.
