摘要：
The invention concerns an intake manifold (1) comprising a plenum (8) and air ducts (13) one of which at least, for each combustion chamber of the engine, has a sudden enlargement (19) of its passage cross-section, immediately followed in downstream direction by a duct portion (20) having a gradually decreasing cross-section and ending (21) upstream of a flange fixing (16) the manifold (1) to the engine and its cylinder head. The plenum (8) and each of the air ducts (13) at least are made of synthetic material, preferably capable of being moulded. The invention is useful for equipping internal combustion engine with pistons driven in reciprocating movement in the cylinders.
