Description

Die Erfindung bezieht sich auf einen Abgaskrümmer für einen Verbrennungsmotor der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to an exhaust manifold for an internal combustion engine of the type explained in the preamble of claim 1.

Abgaskrümmer werden häufig isoliert, insbesondere dann, wenn die Abgastemperatur für nachgeschaltete Aggregate, wie beispielsweise einen Katalysator oder einen Turbolader oder dgl., möglichst frühzeitig ein hohes Niveau erreichen soll, damit die nachgeschalteten Aggregate korrekt arbeiten können bzw. die Konstruktion aus niederwertigen Materialien aufgebaut werden können bzw. diese überhaupt funktionieren.Exhaust manifolds are often isolated, especially if the exhaust gas temperature for downstream units, such as a catalyst or a turbocharger or the like. As early as possible to achieve a high level so that the downstream units can work properly and the construction of low-grade materials are constructed can or do this work at all.

Die DE 195 36 124 A1 offenbart einen Abgaskrümmer für eine Abgasanlage eines Verbrennungsmotors mit einem die Innenseite des Krümmers bildenden Rohr mit mindestens einem Anschlussstück zur Verbindung mit mindestens einem Brennraum des Verbrennungsmotors und mit einer um das Rohr herum angeordneten Wärmedämmschicht.The DE 195 36 124 A1 discloses an exhaust manifold for an exhaust system of an internal combustion engine having a tube forming the inside of the manifold with at least one connector for connection to at least one combustion chamber of the internal combustion engine and with a thermal barrier coating disposed around the pipe.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders wirksame Art einer Isolierung für einen Abgaskrümmer bereitzustellen. Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The invention has for its object to provide a particularly effective way of insulation for an exhaust manifold. The object is solved by the features specified in claim 1.

Die Erfindung stellt einen Abgaskrümmer für einen Verbrennungsmotor, mit einem abgasführenden Innenrohr, einer äußeren Ummantelung und einer Isolierung, wobei die Isolierung als in Form gepresstes Isolierformteil ausgebildet und zwischen der Ummantelung und dem Innenrohr angeordnet ist und ein Isolierfasergewebe und ein Bindemittel enthält; wobei das Isolierfasergewebe eine Fasermatte aus mineralischen Fasern, wie eine Glas- und/oder Silikat- und/oder Keramikfaser-Gewebematte enthält; und wobei das Isolierformteil durch einen Luftspalt vom Innenrohr getrennt ist; wobei diejenige Seite des Isolierformteiles, die aus der Fasermatte besteht, am Luftspalt angeordnet ist und die gegenüberliegende Seite des Isolierformteils an der Ummantelung anliegt; wobei die Ummantelung das Innenrohr im Abstand A umgibt; wobei das Isolierformteil die gesamte Innenoberfläche der Ummantelung bedeckt, jedoch dünner als der Abstand A ist, so dass zwischen dem Isolierformteil und dem Innenrohr ein isolierender Luftspalt verbleibt, wobei das Isolierformteil dünner als der isolierende Luftspalt ist.The invention provides an exhaust manifold for an internal combustion engine having an exhaust gas carrying inner tube, an outer shell and an insulation, the insulation being formed as a molded insulating member and disposed between the shell and the inner tube and including an insulating fiber fabric and a binder; wherein the insulating fiber fabric contains a fiber mat of mineral fibers, such as a glass and / or silicate and / or ceramic fiber fabric mat; and wherein the Isolierformteil is separated by an air gap from the inner tube; wherein the side of the Isolierformteiles, which consists of the fiber mat, is disposed at the air gap and the opposite side of the Isolierformteils rests against the jacket; wherein the jacket surrounds the inner tube at a distance A; wherein the Isolierformteil covers the entire inner surface of the sheath, but is thinner than the distance A, so that an insulating air gap remains between the Isolierformteil and the inner tube, wherein the Isolierformteil is thinner than the insulating air gap.

Das zum Formpressen des Isolierformteiles verwendete Bindemittel kann Tonerde, insbesondere Bentonit sein.The binder used to mold the Isolierformteiles may be alumina, in particular bentonite.

Es ist weiterhin möglich, das Isolierformteil mit Pigmenten zu versetzen, die wärmeabsorbierend bzw. wärmereflektierend wirken.It is also possible to provide the Isolierformteil with pigments that act heat absorbing or heat reflecting.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der einzigen Figur erläutert, die einen Schnitt durch einen schematisch dargestellten, erfindungsgemäßen Abgaskrümmer zeigt.An embodiment of the invention will be explained with reference to the single figure, which shows a section through a schematically illustrated, according to the invention the exhaust manifold.

Fig. 1 zeigt in schematischer Darstellung einen Schnitt durch einen Abgaskrümmer 1 für einen Verbrennungsmotor, bevorzugt für Kraftfahrzeuge. Fig. 1 shows a schematic representation of a section through an exhaust manifold 1 for an internal combustion engine, preferably for motor vehicles.

Der Abgaskrümmer 1 enthält die üblichen abgasführenden Innenrohre 2, die im Abstand A von einer Ummantelung 3 umgeben sind. Die Abgasrohre 2 und die Ummantelung 3 können aus den üblichen Materialien, wie Guss oder Stahlblech, bestehen.The exhaust manifold 1 contains the usual exhaust-carrying inner tubes 2, which are surrounded by a sheath 3 at a distance A. The exhaust pipes 2 and the casing 3 may consist of the usual materials, such as cast or steel sheet.

Im Abstand A ist eine Innenisolierung 4 untergebracht. Die Innenisolierung 4 bedeckt bevorzugt die gesamte Innenoberfläche der Ummantelung 3, ist jedoch dünner als der Abstand A, so dass trotz Einbau der Isolierung 4 ein isolierender Luftspalt 5 zum Innenrohr 2 verbleibt.At a distance A, an inner insulation 4 is housed. The inner insulation 4 preferably covers the entire inner surface of the sheath 3, but is thinner than the distance A, so that despite installation of the insulation 4, an insulating air gap 5 to the inner tube 2 remains.

Die Isolierung 4 ist zwischen 1 mm und 3 mm, bevorzugt zwischen 1,5 mm bis 2 mm dick, so dass der Luftspalt 5 gegenüber dem Abstand A um diesen Betrag verringert wird.The insulation 4 is between 1 mm and 3 mm, preferably between 1.5 mm to 2 mm thick, so that the air gap 5 is reduced relative to the distance A by this amount.

Die Isolierung 4 ist als Isolierformteil ausgebildet. Das Isolierformteil enthält eine Trägermatte in Form eines Gewebes aus isolierenden Fasern, insbesondere Silikatfasern, aber auch Glasfasern oder dgl.. Die Isolierfasergewebe sind handelsüblich und bestehen aus quer- und längsverlaufenden Fäden, die miteinander mit den unterschiedlichsten, aus dem Textilbereich bekannten Bindungsarten verflochten sind. Ein besonders bevorzugtes Ausführungsbeispiel eines Isolierfasergewebes ist unter der Marke Hakoterm® 1200 HG 1305 im Handel. Dieses Material besteht aus gezwirnten Silikatfasern, die zu einer Gewebematte verwebt wurden.The insulation 4 is formed as Isolierformteil. The Isolierformteil contains a support mat in the form of a fabric of insulating fibers, in particular silicate fibers, but also glass fibers or the like .. The Isolierfasergewebe are commercially available and consist of transverse and longitudinal threads, which are intertwined with the most diverse, known from the textile sector binding types. A particularly preferred embodiment of an insulating fiber fabric is commercially available under the trademark Hakoterm® 1200 HG 1305. This material consists of twisted silicate fibers that have been woven into a fabric mat.

Statt Gewebematten aus Silikatfasern sind jedoch auch Glasfasergewebe oder Gewebe aus ähnlichen für eine Isolierung geeigneten Fasern, z.B. Mineralfasern, einsetzbar.Instead of fabric mats made of silicate fibers, however, it is also possible to use glass fiber fabrics or fabrics made of similar fibers suitable for insulation, for example mineral fibers.

Zum Herstellen des Isolierformteiles wird ein passender Zuschnitt des Isolierfasergewebes mit einem herkömmlichen Bindemittel, beispielsweise Tonerde in Form von Betonit, aufgeschlämmt im Wasser, versehen und anschließend durch Heißpressen in Endform gebracht.To produce the Isolierformteiles a matching blank of Isolierfasergewebes with a conventional binder, such as clay in the form of concrete, slurried in water, provided and then brought by hot pressing in final form.

Dem Bindemittel können Farbpigmente zugesetzt werden, die die Wärmeabsorption und/oder Wärmereflexion in einer Weise beeinflussen, dass einerseits die umgebenden Bauteile gegen thermische Überlastung geschützt und andererseits dafür gesorgt wird, dass beim Anfahren des Verbrennungsmotors sehr schnell eine Erhöhung der Abgasenergie erreicht wird, was zu einem schnellen Anstieg der Temperatur in der Abgasleitung während der Anlaufzeit und dadurch zu einer Reduzierung der NOx-Werte und des CO2-Ausstoßes führt.Color pigments can be added to the binder which influence the heat absorption and / or heat reflection in such a way that, on the one hand, the surrounding components are protected against thermal overloading and, on the other hand, it is ensured that an increase in the exhaust gas energy is achieved very rapidly when the internal combustion engine starts up a rapid increase in the temperature in the exhaust pipe during the start-up period and thereby leads to a reduction of the NO x values and the CO 2 emission.

Ein besonders geeignetes Farbpigment ist ein schwarzer Kupferchromitspinell, wie er beispielsweise als Black 30C965 von der Firma "The Shepherd Color Company" erhältlich ist. Dieses Farbpigment wirkt vorwiegend absorbierend. Ein bevorzugt reflektierendes Farbpigment ist ein gelbes Farbpigment (Polier-Rutil auf Chrom/Antimon/Titan-Basis), bevorzugt YELLOW 193 der gleichen Firma.A particularly suitable color pigment is a black Kupferchrromitspinell, as it is available, for example, as Black 30C965 from the company "The Shepherd Color Company". This color pigment is predominantly absorbent. A preferred reflective color pigment is a yellow color pigment (polished rutile on chromium / antimony / titanium-based), preferably YELLOW 193 of the same company.

Die Farbpigmente werden bevorzugt dem Bindemittel zugemischt, können jedoch auf irgendeine andere Weise auf oder in dem Isolierformkörper gelangen.The color pigments are preferably admixed with the binder, but can be applied to or in the Isolierformkörper in any other way.

Der Einbau des Isolierformteiles 4 erfolgt derart, dass die Gewebeseite des Isolierformteiles, d.h. diejenige Seite, die aus der Gewebematte besteht oder den größeren Anteil an der Gewebematte aufweist, am Luftspalt 5 und die gegenüberliegende Seite an der Ummantelung 3 anliegt. Dadurch wird sichergestellt, dass ein größtmöglicher Schutz gegen das Ausblasen und Lockerwerden durch Vibrationen oder dgl. von Bestandteilen der Isolierung gegeben ist, so dass die Gefahr von Betriebsstörungen durch verblasene oder sonst wie verlagerte Partikel im Abgassystem nicht gegeben ist. Das Isolierformteil 4, das auf diese Weise hergestellt wurde, ist selbsttragend, so dass keine zusätzliche Schutzschicht, wie beispielsweise eine Metallfolie oder dgl. zur Abgrenzung bzw. zur mechanischen Stabilisierung notwendig ist. Das Isolierformteil 4 kann einfach an der äußeren Ummantelung 3 befestigt und die Ummantelung 3 zusammen mit der Isolierung 4 mit dem erforderlichen Luftspalt 5 um die Innenrohre 2 herum befestigt werden.The installation of the Isolierformteiles 4 takes place such that the fabric side of the Isolierformteiles, i. the side which consists of the fabric mat or has the greater proportion of the fabric mat, the air gap 5 and the opposite side of the sheath 3 is applied. This ensures that the greatest possible protection against the blowing out and loosening by vibration or the like. Of components of the insulation is given, so that the risk of malfunction by blown or otherwise displaced particles in the exhaust system is not given. The Isolierformteil 4, which was prepared in this way, is self-supporting, so that no additional protective layer, such as a metal foil or the like. For delimitation or for mechanical stabilization is necessary. The Isolierformteil 4 can be easily attached to the outer sheath 3 and the sheath 3 are fastened together with the insulation 4 with the required air gap 5 around the inner tubes 2 around.
