Abstract

Inlet manifolds such as intake manifolds, collector tanks, intake pipes, oscillatory intake passages, systems with variable-tract intake manifolds etc., for internal combustion engines operating on the principle of the diesel or Otto engine, where the inlet manifold includes two or more dish-shaped parts that are permanently joined to each other, and the dish-shaped parts are formed sheet parts, castings and/or extruded sections of metal. The permanent joining of the dish-shaped parts may be effected e.g. by adhesive bonding and/or welding.
