Air-supply module for internal combustion engine

摘要

An air-supply module including an air cleaner case, a throttle body, a surge tank, manifold pipes and other components is integrated into one single unit. The module is mounted as a whole on an internal combustion engine by simply connecting a flange formed at an eigne side end of the manifold pipes to intake ports of the engine. Bolts sticking out of the intake ports are inserted into mounting holes formed on the flange, and nuts are screwed onto the bolts by a nut runner. The mounting holes on the flange are located between the manifold pipes so that the nut runner can reach the nuts directly from the outside of the module without disassembling any components already assembled into the module. Other components including the air cleaner case are disposed in the module to secure a tool space and not to interfere with the mounting operation.
