Patent number: 8375903Abstract: An internal combustion engine has at least one intake valve and at least one exhaust valve. A first spring biases the at least one intake valve to a closed position. A second spring biases the at least one exhaust valve to a closed position. At least one of the first and second springs is an air spring. An air compressor is disposed inside the cylinder head and fluidly communicates with the air spring to supply air to the air spring. The air compressor being disposed between a crankshaft and a cylinder head cover in a direction parallel to a cylinder axis is also disclosed.Type: GrantFiled: January 20, 2010Date of Patent: February 19, 2013Assignee: BRP-Powertrain GmbH & Co.

Patent number: 5901677Abstract: An inlet pipe system for a multicylinder internal combustion engine, especially with two rows of cylinders in a V-configuration, has a tubular inlet distributor 2, from which first individual inlet pipes 4 through 9 proceed which extend in an arc around the inlet distributor and which lead to the individual cylinders of the two rows of cylinders. Second, shorter individual inlet pipes 12 likewise proceed from the inlet distributor and discharge into the pertinent individual inlet pipes. The inlet distributor and the first and second individual inlet pipes are formed by a one-piece part 1 which has a longitudinal hole 14 which cuts the second individual inlet pipes 12 for the cylinders of the two rows of cylinders. Into longitudinal hole 14 a drum controller 15 is inserted which for each second individual inlet pipe 12 has an opening 16 which can be brought into alignment or out of alignment with the pertinent second individual inlet pipe by turning the drum controller 15.Type: GrantFiled: December 22, 1994Date of Patent: May 11, 1999Assignee: Audi AGInventors: Gerd Ohrnberger, Helmut Dillig

Patent number: 5492088Abstract: An intake pipe system for a multicylinder internal combustion engine, in particular one with two cylinder banks arranged to form a V, has a tubular intake distributor 2 from which extends a first set of individual intake pipes 4 to 9 which extend through an arc around the intake distributor and lead to the individual cylinders of the two cylinder banks. A second set of shorter individual intake pipes also extend from the intake distributor and discharge into the associated individual intake pipes. The intake distributor and the first and second sets of individual intake pipes are made up of an integral casting 1 having a longitudinal bore 16 intersecting the second set of individual intake pipes. There is introduced into each longitudinal bore 16 a casing having openings 17 aligned with the second set of individual intake pipes, in which bore a pivoting valve 14 is mounted on a common shaft 20 which is embedded in the casing 15.Type: GrantFiled: April 13, 1995Date of Patent: February 20, 1996Assignee: Audi AGInventor: Gerd Ohrnberger
