Abstract

  • 2.1. Es wird eine Brennkraftmaschine für ein Kraftfahrzeug vorgeschlagen, mit einem Brennraum, dem ein Einlasskanal zur Zufuhr von Brenngas, ein Auslasskanal zur Abfuhr von Verbrennungsprodukten sowie
    eine Kraftstoffversorgungseinheit zur Zufuhr von flüssigem Kraftstoff zugeordnet sind.    2.1. It is proposed an internal combustion engine for a motor vehicle, with a combustion chamber, an inlet channel for supplying fuel gas, an outlet channel for the removal of combustion products and
    a fuel supply unit for supplying liquid fuel are assigned.
  • 2.2. Erfindungsgemäß ist bei der Brennkraftmaschine der Auslasskanal in einem Abgaskrümmer aus einem dünnwandigen Metallblech mit einer aufgerauhten Innenoberfläche zur Adsorption von unverbranntem oder teilverbranntem Kraftstoff angeordnet.
    Eine Strukturierung der Innenoberfläche des Abgaskrümmers erfolgt ganz oder teilweise vorzugweise über spanendes oder spanloses Umformen, chemisches Ätzen, pulvermetallurgisches Beschichten oder mittels einer Kombination aus den genannten Oberflächenbehandlungsverfahren.    2.2. According to the invention, in the internal combustion engine, the exhaust passage is arranged in an exhaust manifold made of a thin-walled metal sheet with a roughened inner surface for the adsorption of unburned or partially combusted fuel.
    A structuring of the inner surface of the exhaust manifold takes place wholly or partly, preferably by means of cutting or non-cutting forming, chemical etching, powder metallurgy coating or by means of a combination of the mentioned surface treatment methods.
  • 2.3. Anwendung in Kraftfahrzeugen, insbesondere Personenkraftwagen.2.3. Application in motor vehicles, in particular passenger cars.
