Exhaust Manifold With Thin Flanges

摘要

An exhaust manifold for an engine has at least one collecting pipe for conveying exhaust gases. Several exhaust gas inlets are in fluid communication with the collecting pipe. Several flanges each define one of the exhaust gas inlets. Each flange has an external face adapted to be pressed against a receiving surface of the engine. Several back flanges are each associated to one of the flanges and are adapted to press the corresponding flange against the receiving surface. The flanges are areas of a single plate, which has a thickness between 0.2 and 2 mm. The areas are continuously connected to one another by other areas of the plate. The collecting pipe is not integral with the plate. The manifold has leak tight connections connecting the collecting pipe to each of the flanges.
