  • Patent number: 6158214
    Abstract: The invention concerns an exhaust silencer arrangement with a transverse exhaust silencer in a four-chamber type of construction, in particular for very small passenger-transporting motor vehicles, with a 3-cylinder rear-mounted engine and an exhaust gas turbocharger. The silencer comprises a housing which is composed of two half shells and accommodates a catalyst module in an integrated manner. The catalyst module, which does not have its own housing, forms a silencer system partition which divides the silencer into a 3-pot main chamber and an additional chamber which is in particular a resonator chamber and communicates with the main chamber via connection ducts formed in the half-shell housing.

  • Patent number: 5623825
    Abstract: In a turbocharger arrangement for an internal combustion engine including an exhaust gas turbine with an exhaust gas pressure control valve (waste gate) and an operating motor for opening or closing the waste gate, wherein a charger is coupled to the turbine and has a suction side and a discharge side in communication with the engine for supplying charge air thereto and wherein a system control valve is provided which is in communication with the suction side and with the pressure side of the charger and also with the waste gate operating motor for supplying suction air pressure or discharge air pressure to the waste gate operating motor, the system control valve includes means for placing the suction air side of the charger in communication with the charger air discharge side for returning charger discharge air to the suction side of the charger.

  • Patent number: 5435358
    Abstract: A closure for a fuel tank filler neck has a closure cap which is swivel-mounted on the upper side of the said closure and can be opened from the closed position by the effect of force on a lever arm arranged on the far side of the swivel axis. A pawl for locking and unlocking of the closure cap is swivellable and prestressed in the closing sense or direction by spring force and has an outwardly extending lever arm for mechanically lifting the pawl against the spring force. To ensure a permanent and reliable closing function of the closure cap, the filler neck bears an axially accessible adjusting ring which is arranged coaxially with respect to the cap. The ring is mounted rotatably on the outer circumference of the latter and/or on the axial end face of a shoulder thereof, and has on its upper side, at least in a subregion, a spiral toothing. A toothed segment is arranged on the lever arm of the closure cap.

  • Patent number: 5277026
    Abstract: In an exhaust system for an internal combustion engine having a main exhaust conduit with a catalytic converter arranged remote from the engine and a bypass exhaust conduit which includes a start-up catalytic converter arranged close to the engine and joins the main exhaust gas conduit ahead of said remote catalytic converter, an ejector structure is arranged in the main exhaust gas conduit within a housing defining a suction chamber in communication with the bypass exhaust conduit for drawing gas through the bypass exhaust conduit into said main exhaust gas conduit whenever exhaust gas flows from the engine through the main exhaust gas conduit and a main exhaust conduit valve is arranged between the ejector structure and the junction of the main and the bypass exhaust conduits which is closed during start-up operation of the engine to thereby force the exhaust gas to flow through the suction chamber and the bypass exhaust gas conduit via the start-up catalytic converter.
