Abstract:
An air-supply module for an internal combustion engine having intake ports aligned to define an engine cylinder alignment direction and having an air intake direction perpendicular to said engine cylinder alignment direction, the air supply module comprising:an air-intake passage defining an air flow path extending in a direction generally perpendicular to said engine cylinder alignment direction;a surge tank connected to the air-intake passage for alleviating pulsation of air sucked thereinto;a plurality of manifold pipes connecting the surge tank and the intake ports of the engine, the manifold pipes being oriented generally in planes that are generally perpendicular to said engine cylinder alignment direction; anda flange to which the manifold pipes are connect at their intake port side, the flange including means for mounting the air-supply module on the engine, wherein:the air-intake passage, the surge tank, the plurality of manifold pipes and the flange are all integrated into a single unit to form the air-supply module which can be mounted on the engine as said single unit by the mounting means; anda tool space is provided which permits a tool for mounting the air-supply module on the engine to reach the mounting means directly from an outside of the air-supply module, whereby the air-supply module is adapted to bc mounted on the engine as said single unit.
