Description

DaimlerChrysler AGDaimlerChrysler AG

BrennkraftmaschineInternal combustion engine

Die Erfindung betrifft eine Brennkraftmaschine mit einem Ladeluftverdichter und mindestens einem aufladbaren Verbrennungsraum, wobei der Verbrennungsraum zumindest teilweise durch tribologisch beanspruchte Gleitflächen begrenzt ist.The invention relates to an internal combustion engine with a charge air compressor and at least one chargeable combustion chamber, the combustion chamber being at least partially limited by tribologically stressed sliding surfaces.

Es sind" bereits aufgeladene Brennkraftmaschinen allgemein bekannt. Dabei sind bei der Verwendung von Aluminium als Grundwerkstoff für die Motorenblöcke bzw. Zylinderköpfe neben dem Einsatz von Zylinderlaufbuchsen aus Grauguss auch alternative Zylinderlaufflächen bekannt, insbesondere für Dieselmotoren.Already supercharged internal combustion engines are generally known. When using aluminum as the base material for the engine blocks or cylinder heads, in addition to the use of cylinder liners made of cast iron, alternative cylinder liners are also known, in particular for diesel engines.

Aus der DE 100 36 264 AI ist ein Verfahren zur Herstellung einer Oberflächenschicht mit intermetallischen Phasen auf Trägerelementen bekannt. Besonders geeignet als Trägerelemente sind Bauteile, die im Antriebsstrang und Fahrwerk eines Kraftfahrzeuges eingesetzt werden und hohen tribologischen Belastungen ausgesetzt sind. Hierzu zählen u. a. Zylinderkurbelgehäuse, Zylinderköpfe, Kolben, Getriebegehäuse und Synchronringe.DE 100 36 264 A1 discloses a method for producing a surface layer with intermetallic phases on carrier elements. Components that are used in the drive train and chassis of a motor vehicle and are exposed to high tribological loads are particularly suitable as carrier elements. These include u. a. Cylinder crankcase, cylinder heads, pistons, gearbox and synchronizer rings.

Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine derart auszubilden und anzuordnen, dass eine optimale Aufladung gewährleistet ist. Gelöst wird die Aufgabe erfindungsgemäß dadurch, dass zumindest die Gleitfläche des Verbrennungsraumes mit einer Metall-Keramik-Beschichtung versehen ist. Hierdurch wird erreicht, dass gerade aufgrund der durch die Aufladung steigenden Belastung der Motoren die Verschleißfestigkeit der Laufbahn des Verbrennungsraumes gewährleistet ist. Mit der Verschleißfestigkeit wird ein nachteiliges Kolbenspiel verhindert, sodass der Ladungswirkungsgrad steigt .The object of the invention is to design and arrange an internal combustion engine in such a way that optimal charging is ensured. The object is achieved according to the invention in that at least the sliding surface of the combustion chamber is provided with a metal-ceramic coating. This ensures that the wear resistance of the combustion chamber raceway is guaranteed precisely because of the increasing load on the engines due to the supercharging. The wear resistance prevents disadvantageous piston play, so that the charge efficiency increases.

Hierzu ist es vorteilhaft, dass dem Verbrennungsraum mehrere Zylinder und mindestens eine ein Kurbelwellenlager aufweisende Kurbelwelle zugeordnet sind, wobei das Kurbelwellenlager durch einen Lagerrahmen unterstützt ist. Die mit der Aufladung anwachsende Lagerhaltekraft wird durch die Verwendung eines Lagerrahmens, insbesondere in Verbindung mit einer verschleißfesten Laufbahn des Verbrennungsraumes, gewährleistet .For this purpose, it is advantageous for the combustion chamber to be assigned a plurality of cylinders and at least one crankshaft having a crankshaft bearing, the crankshaft bearing being supported by a bearing frame. The bearing holding force that increases with the charge is ensured by the use of a bearing frame, in particular in connection with a wear-resistant raceway of the combustion chamber.

Eine zusätzliche Möglichkeit ist gemäß einer Weiterbildung, dass der Zylinder eine Zylinderinnenseite und einen Kolben aufweist, wobei die Zylinderinnenseite und die Kolbenlauffläche mit der Metall-Keramik-Beschichtung versehen ist. Gerade bei Verwendung von Kolbenbrennkraftmaschinen gewährleistet der Einsatz der Metall-Keramik- Beschichtung mit Rücksicht auf ein nachteiliges, durch Verschleiß bedingtes Kolbenspiel eine optimale Aufladung.According to a further development, an additional possibility is that the cylinder has a cylinder inside and a piston, the cylinder inside and the piston running surface being provided with the metal-ceramic coating. Especially when using piston internal combustion engines, the use of the metal-ceramic coating ensures optimum charging due to a disadvantageous piston play caused by wear.

Vorteilhaft ist es hierzu auch, dass die Metall-Keramik- Beschichtung durch Auftragen einer Keramik eκ und eines Metalls Mes und gleichzeitiges und/oder nachträgliches Erhitzen gebildet ist, wobei Meκ ein in der Keramik chemisch gebundenes Metall, X ein Nichtmetall aus der Gruppe Sauerstoff, Kohlenstoff, Bor und/oder Stickstoff und Mes ein in der aufgebrachten Schicht in elementarer Form oder als Legierungsbestandteil enthaltenes Metall ist. Ge äß einer bevorzugten Ausführungsform der erfindungsgemäßen Lösung ist schließlich vorgesehen, dass Mes Aluminium ist.It is also advantageous for this that the metal-ceramic coating is formed by applying a ceramic e κ and a metal M e s and simultaneous and / or subsequent heating, where M e κ is a metal chemically bonded in the ceramic, X a non-metal from the group oxygen, carbon, boron and / or nitrogen and M it is a metal contained in the applied layer in elemental form or as an alloy component. Finally, according to a preferred embodiment of the solution according to the invention it is provided that M e s is aluminum.

Von besonderer Bedeutung ist für die vorliegende Erfindung, dass in der aufgebrachten Schicht eine oxidische Keramik MeΞX wie Titanoxid, Siliziumoxid und/oder ein Mischoxid wie Spinelle, Silikate oder Ilmenit enthalten ist .It is of particular importance for the present invention that an oxide ceramic M eΞ X such as titanium oxide, silicon oxide and / or a mixed oxide such as spinels, silicates or ilmenite is contained in the applied layer.

Im Zusammenhang mit der erfindungsgemäßen Ausbildung und Anordnung ist es von Vorteil, dass Meκ ein Übergangsmetall, ein Halbmetall wie Silizium und/oder Titan ist. In connection with the design and arrangement according to the invention, it is advantageous that M e κ is a transition metal, a semimetal such as silicon and / or titanium.
