Exhaust manifold assembly |
摘要 |
An exhaust manifold may include a manifold body and a flange. The manifold body may include a first tube that forms an exhaust gas inlet. The flange may be coupled to the manifold body and may fix the manifold body to an engine. The flange may include a first aperture having first and second portions located along an axial extent of the first aperture. The first portion may extend to a first end surface of the flange and the second portion may extend to a second end surface of the flange. The first portion may have a first radial width that is less than a second radial width of the second portion. The second portion may receive an end of the first tube therein. The first tube may be fixed to the flange at a location within the first aperture between the first portion and the second end surface.
