Air intake duct for internal combustion engine of vehicle, has duct sections connected to each other, where connections between sections are carried by chemical positive connection at level of connection zone that form link in duct

摘要

The duct has duct sections (2-4) made of different materials and connected to each other in conditions of sealing and resisting against applied loads. Each duct section has elasticity and/or rigidity properties adapted to a function of the duct positioned in a positioning zone of the duct section in an internal combustion engine. Connections between the duct sections are carried by a chemical positive connection at the level of a connection zone that forms a link in the duct.
