    Abstract: In an intake system of a variable air-intake characteristic type for a multi-cylinder engine, an intake air-dispensing box is comprised of a dispensing box body which includes an intake air inlet, first and second intake branch pipes and one of halves of a partition wall and which has an opening provided in its outer wall opposite from the first and second intake branch pipes to extend between first and second dispensing chambers, and a lid detachably coupled to the dispensing box body to close the opening and having the other half of the partition wall. The lid is made of a light alloy by casting, and a valve bore and bearing bores for supporting a valve shaft of the on-off valve are defined in the other half of the partition wall. Thus, it is possible to carry out the maintenance of the on-off valve only by removing the lid disposed outside the intake air-dispensing box from the box, leading to an enhancement in maintenance property.

    Abstract: An intake manifold made of a synthetic resin includes a surge tank, and a plurality of intake pipes disposed in parallel to one another and each having a rising pipe portion which is connected to a lower portion of the surge tank and extends upwards. A space is defined between the surge tank and each of the rising pipe portions, as viewed sideways. In order to enable an increase in volume of the surge tank, while avoiding an increase in size of the intake manifold, the surge tank (20) includes a main tank portion (20a) extending in a direction (28) of arrangement of the intake pipes (21A to 21D) and opposed to the rising pipe portions (29A to 29D) of the intake pipes (21A to 21D), and a sideways-bulged portion (20b) which is bulged from an intermediate portion of the main tank portion (20a) as viewed in the arrangement direction (28) and is interposed between a pair of rising pipe portions (29B, 29C) disposed at the intermediate portion as viewed in the arrangement direction 28. Inner ends of a pair of the spaces (38) defined respectively between the rising pipe portions (29A to 29D) and the main tank portion (20a) on opposite sides of the sideways-bulged portion (20b) are closed by opposite sidewalls of the sideways-bulged portion (20b).

    Abstract: A invention provides an integrated splash shield and air intake tube are provided. A splash shield defining a wheel well is at least partially arranged about a wheel. The splash shield has first and second portions secured to one another defining an air passageway with the air passageway in fluid communication with the engine. A wheel well portion has a second surface opposite a first surface. An air intake portion is supported on the wheel well portion and preferably secured thereto by a weld bead. The air intake portion and the first surface of the wheel well portion together define an air passageway having an inlet for receiving ambient air and an outlet for connection to an engine throttle of the engine. Other air passages may be defined in a similar manner in the integrated splash shield and air intake tube described above. For example, a passive noise cancellation system such as a Herschel-Quincke tube arrangement may be formed by the wheel well and air intake portions. The integrated splash shield and air intake tube may be formed by any suitable plastic forming process, such as by blow or injection molding. The wheel well and air intake portions may be constructed from numerous pieces and secured to one another by a weld bead.

    Abstract: A suction system for an internal-combustion engine is provided with at least one container, which can be connected by way of feed pipes with the intake ports of a cylinder head. Openings of the intake ports for charge cycle control are monitored by valves. In the container or in the feed pipes, at least one reflection chamber is provided, which is connected with the interior volume of the container by way of a hole structure. The hole structure is formed by a plurality of openings that are formed in a wall section of the container, and are closed off by a cover fastened to the exterior side of the container wall, providing a reflection chamber which reduces noise in the suction system without adversely affecting air flow in the interior of the suction system.
