Abstract: An air intake, especially for internal combustion engines with a V-shaped cylinder arrangement, which is composed of two units (16a, 16b). From the two units (16a, 16b) extend the intake ducts (19a, 19b), each associated with one cylinder bank (11) of the internal combustion engine. By dividing the air intake device into two units (16a, 16b), the unit (16a) can be mounted first on the internal combustion engine, a free space (20) for the mounting tool being necessary. Then the unit (16b) is placed and bolted on, the air intake ducts (19b) being able to run through the free space (20) in the hatched area (23), since the unit (16a) is already installed. The advantage of this air intake tube configuration is a substantially greater geometric freedom of design.

Abstract: A mounting arrangement for an intake manifold and a method of making same. The mounting arrangement includes an adapter plate attached to a cylinder head of an engine. The adapter plate has at least one aperture having a smooth inner surface. The intake manifold includes at least one inlet pipe and is mounted to the adapter plate by arranging the at least one inlet pipe in the at least one aperture of the adapter plate. A securing mechanism is arranged between the at least one inlet pipe and the smooth inner surface of the at least one aperture. The mounting arrangement of the present invention substantially isolates the intake manifold from vibrations caused by the operation of the engine, which in the past have been transmitted to the intake manifold by way of mounting flanges.

Abstract: A combined air intake manifold and fuel delivery rail for an internal combustion engine which decreases manufacturing and assembly costs, as well as the weight of the engine. An air channel formed in a hollow portion of the manifold registers with air intake ports in the engine head which lead to the individual cylinders of the engine. An elongated recess in the underside of a mounting flange forms a fuel supply channel which communicates with fuel inlet openings in the engine head leading to fuel injectors for the engine cylinders. Seals may be provided between the manifold and the engine head to seal the air channel and the fuel supply channel.
