  • Patent number: 6557512
    Abstract: An adjustable intake pipe, especially for supplying combustion air to an internal combustion engine, which includes a collector chamber arranged in an essentially cylindrical control element. The collector chamber has a larger volume than required for the air supply, so the chamber is not used efficiently. In the invention, the collector chamber volume is used by arranging additional components of the intake tract defined by the intake pipe, i.e. of an internal combustion engine, within the collector chamber (11), for example, by arranging a resonance chamber (20) therein with the resonance chamber connected to the air supply system by through holes (19). This arrangement better utilizes the chamber volume and is particularly advantageous in motor vehicle engine compartments where limited space is available. The intake system also is more compact and has a lower overall weight.

  • Publication number: 20030024513
    Abstract: An intake system (13) for an internal combustion engine (12) which includes a housing (15a) with a filter insert (16) and a membrane (22) for separating nitrogen and enriching the combustion air with oxygen. The membrane is integrated into the filter housing so as to save construction space and provide a lower cost system. The membrane (22) can alternatively be arranged on the clean air side of the air filter insert (16) to prevent the membrane from being soiled and to improve the functional reliability of the oxygen enrichment. Alternatively, instead of arranging the membrane (22) on the clean side of the filter insert (16), the membrane can be protected from being soiled by using a cover (23).

  • Publication number: 20020082264
    Abstract: Chromanone derivatives are highly active antiviral agents. Combinations of chromanones and/or chromanols with HBV polymerase inhibitors, HBV DNA inhibitors or HBV core protein inhibitors and/or isoxazoles and, where appropriate, interferon inhibit the replication of HBV viruses better than agents disclosed previously.

  • Publication number: 20020020382
    Abstract: An adjustable intake pipe, especially for supplying combustion air to an internal combustion engine, which includes a collector chamber arranged in a control element which has an essentially cylindrical configuration. Due to its construction, the collector chamber has a larger volume than required for the air supply, so that the chamber is not used efficiently. In accordance with the invention, the collection chamber is used in such a way that additional components of the intake tract defined by the intake pipe, i.e. the intake tract of an internal combustion engine, can be arranged in the collection chamber volume. This can be achieved, for example, by arranging a resonance chamber (20) within the collector chamber (11) with the resonance chamber being connected to the air supply system by through holes (19).

  • Patent number: 6334436
    Abstract: A secondary air system 10 is proposed for an internal combustion engine, which has a turbine 11 driven by a pressure gradient in the intake air and a compressor 14 driven by the turbine 11. The turbine is connected by a turbine inlet line 12 and a turbine outlet line 13 to an air intake duct 20. The compressor 14 has a compressor inlet line 15 and a compressor outlet line 16. The cold produced by the turbine 11 is used by a turbine heat exchanger 17 and transport lines 27 for the cooling of, e.g., oil. The heat produced by the compressor 14 is used by a compressor heat exchanger 18 and the transport lines 27 connected thereto, e.g., for heating air.

  • Patent number: 6224531
    Abstract: A rotor (1) designed to be installed in the housing (16) of a free jet centrifuge, the rotor being provided with at least one inlet (3) and at least one outlet (4), which outlet is configured as a nozzle which is oriented at least substantially tangentially to the axis of rotation (13) of the rotor. The rotor is provided with receptacles for bearings for rotatably mounting the rotor, and the rotor having at least one guide element (7) which extends from an inner wall (38) to an outer wall (39) of a rotor interior space (8). At least the rotor shell (11) is made of synthetic resin material. Owing to its form, the synthetic resin centrifuge rotor can be made up of a reduced number of parts. The rotor may be composed of two elements, a base (10) and a shell (11), connected together either by a snap connection or by welding, such as vibration welding. An oil centrifuge fitted with such a rotor is particularly suitable for cleaning lubricating oil used in an internal combustion engine.
