Abstract (en)
[origin: US2002112708A1] A fluid feed duct, which may be used for feeding a stream of recirculated exhaust gas into a stream of intake air for an internal combustion engine. The feed duct includes a hollow structure (10) into which a feed connection (12) is introduced via a joint structure (34). A ceramic pipe (16) is used to prevent heat from the exhaust gas stream from being conducted to mounts in the hollow structure (10) which represents the intake duct of the engine. Consequently, the intake duct can be manufactured of a thermoplastic synthetic resin material, since the risk of thermal overstressing is avoided. The feed connection also has a deflecting segment (19) which is provided in its sides with outlet openings (20). This enables the exhaust gas to be introduced in the direction of flow of the intake air, so that optimal mixing is assured and the hot exhaust gas stream is prevented from passing directly to the wall of the thermoplastic intake duct, thereby preventing the intake duct from being melted.
