Abstract

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. DOLLAR A 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. DOLLAR A Eine Strukturierung der Innenoberfläche des Abgaskrümmers erfolgt ganz oder teilweise vorzugsweise über spanendes oder spanloses Umformen, chemisches Ätzen, pulvermetallurgisches Beschichten oder mittels einer Kombination aus den genannten Oberflächenbehandlungsverfahren. DOLLAR A Anwendung in Kraftfahrzeugen, insbesondere Personenkraftwagen.It is proposed an internal combustion engine for a motor vehicle, with a combustion chamber, which are associated with 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. DOLLAR A According to the invention in the internal combustion engine, the exhaust passage is arranged in an exhaust manifold of a thin-walled metal sheet with a roughened inner surface for the adsorption of unburned or partially combusted fuel. DOLLAR A 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 said surface treatment method. DOLLAR A application in motor vehicles, especially passenger cars.
