摘要

An air intake device for an internal combustion engine according to the invention comprises an elongated surge tank (34,136) and inlet pipes (26,130) interconnecting the interior of the surge tank to one inlet port (15,109) each of the engine. Each inlet pipe comprises a substantially horizontal portion (29,131) secured to the cylinder head of the engine as well as a U-shaped portion (27,30;135) extending below the surge tank which U-shaped portion is removeably connected to the surge tank and to the other pipe portion. The assembly according to the invention provides for st iffness and rigidity, facilitates cooling of the intake air and allows for easily replacing the U-shaped portions to fulfill different needs and last not least provides for a compact structure.
