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.

Abstract: In a fuel tank with a filler neck of plastic material which filler neck is connected at one end to the fuel tank and has a filler opening at its other end, a vent pipe extending from the tank to the filler opening, an adsorber chamber with a chamber opening and a fuel vapor conduit providing for communication of the tank with the adsorber chamber are all integrally formed with the filler neck in a single blow molding step, the adsorber chamber, after being filled with a bag of activated carbon, being closed by a lid which carries a regeneration valve and covers the chamber opening.

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.
