Abstract

Ansaugsystem insbesondere für eine Brennkraftmaschine mit einem Rohluftansaugrohr, einem Filtergehäuse und einem Reinluftrohr dadurch gekennzeichnet, dass wenigstens Teile des Rohluftansaugrohres aus gesponnener und gewebter Schafwolle bestehen.Intake system in particular for an internal combustion engine with a raw air intake pipe, a filter housing and a clean air pipe, characterized in that at least parts of the raw air intake pipe consist of spun and woven sheep's wool.

Description

Die Erfindung betrifft ein Ansaugsystem für eine Brennkraftmaschine. Dieses Ansaugsystem einer Brennkraftmaschine weist ein Rohluftansaugrohr auf, dieses besteht üblicherweise aus thermoplastischem Kunststoff und besitzt verschiedene Krümmungen, um insbesondere bei beengten Einbauverhältnissen in einem Kraftfahrzeug die Rohluft zu dem Filtersystem zu leiten. Das Rohluftansaugrohr hat nicht nur die Aufgabe die Rohluft zu führen, sondern auch zur Geräuschreduktion beizutragen. Dazu wird insbesondere bei Kunststoffrohren teilweise eine schallabsorbierende Innenauskleidung verwendet.The invention relates to an intake system for an internal combustion engine. This intake system of an internal combustion engine has a Rohluftansaugrohr, this is usually made of thermoplastic material and has various curvatures, especially in cramped installation conditions in a motor vehicle to direct the raw air to the filter system. The Rohluftansaugrohr not only has the task of guiding the raw air, but also to contribute to noise reduction. For this purpose, a sound-absorbing inner lining is used in part, especially in plastic pipes.

Aus der US 2 868 322 ist ein Ansaugluftverteiler für einen Vergaser bekannt, der an den Lufteinlassöffnungen einen Luftfilter aus Kupfer und Messingwolle aufweist, der von der Luft durchströmt wird und diese in eine turbulente Strömungen versetzt.From the US 2,868,322 an intake manifold for a carburetor is known, which has at the air inlet openings an air filter made of copper and brass wool, which is traversed by the air and these placed in a turbulent flow.

Der US 3 123 102 ist ein hochtemperatur- und flammbeständiges Rohr für ein Fluid zu entnehmen, das aus mehreren Lagen aus Natur- und Kunststofffasern gebildet ist, wobei zur Ausgestaltung einer Ausführungsform Wolle und Nylon als Material angegeben sind.Of the US 3,123,102 is to take a high temperature and flame resistant tube for a fluid which is formed of several layers of natural and synthetic fibers, wherein for the embodiment of an embodiment wool and nylon are given as material.

Es ist auch bekannt, sogenannte Vestaflexrohre zu verwenden, die ebenfalls akustisch gute Eigenschaften aufweisen und eine flexible Gestaltung der Rohluftansaugung ermöglichen.It is also known to use so-called Vestaflex pipes, which also have acoustically good properties and enable a flexible design of Rohluftansaugung.

Der Erfindung liegt die Aufgabe zugrunde, ein Rohluftansaugrohr zu schaffen, welches kostengünstig hergestellt werden kann, hervorragende akustische Eigenschaften besitzt, wasserresistent ist und resourcenschonend produziert werden kann. Diese Aufgabe wird dadurch gelöst, dass zumindest Teile des Rohluftansaugrohres oder das gesamte Rohluftansaugrohr aus gesponnener und gewebter Schafwolle besteht. Schafwolle ist bekanntlichermaßen ein natürlicher nachwachsender Rohstoff. Insbesondere in Schwellenländern wird sehr viel Schafwolle erzeugt und es werden neue Anwendungsfelder gesucht. Aufgrund der hervorragenden Eigenschaften, die solche gewebte Schafwolle besitzt, kann diese für eine Rohluftansaugung verwendet werden. Zur Stabilisierung kann beispielsweise die Schafwolle mit einem Stützgitter oder eingelegten Stützdrähten versehen sein. Eine Imprägnierung der Schafwolle ist aufgrund der wasserabstoßenden Eigenschaften nicht erforderlich, ebenso ist keine Nachbehandlung wie ein Härten oder Temperieren nötig, um die gewünschte Steifheit zu erzielen. Aufgrund der hohen Temperaturfestigkeit der Wolle kann ohne weiteres in einem Spritzgießverfahren diese Schafwolle mit weiteren Rohrteilen verbunden werden.The invention has for its object to provide a Rohluftansaugrohr, which can be produced inexpensively, has excellent acoustic properties, is water resistant and can be produced to save resources. This object is achieved in that at least parts of Rohluftansaugrohres or the entire Rohluftansaugrohr consists of spun and woven sheep's wool. Sheep wool is known to be a natural renewable resource. Especially in emerging countries a lot of sheep's wool is produced and new applications are sought. Due to the excellent properties of such woven sheep's wool, this can be used for Rohluftansaugung. For stabilization, for example, the sheep wool can be provided with a support grid or inserted support wires. An impregnation of the sheep's wool is not required due to the water-repellent properties, as well as no post-treatment such as curing or tempering is necessary to achieve the desired stiffness. Due to the high temperature resistance of the wool can be easily connected in an injection molding this sheep's wool with other pipe parts.

Die Erfindung ist in der Figur dargestellt, diese Figur zeigt ein Rohluftrohr 10 mit einem trichterförmigen Einlass 11. Das Rohluftrohr besteht aus einem gewebten Schafwollschlauch 12, dieser ist an seinen Enden mit den weiteren Teilen über Befestigungsmittel 13, 14 entsprechend verbunden. Der Schafwollschlauch 12 geht über in ein Filtergehäuse 15, in dem sich ein Filterelement 16 befindet. Oberhalb des Filterelements wird die gereinigte Luft einer hier nicht dargestellten Brennkraftmaschine zugeführt. Sofern die angesaugte Rohluft Feuchtigkeit oder Wassertröpfchen enthält, wird diese Feuchtigkeit bzw. werden die Wassertröpfchen von der Wandung aufgenommen und können nach außen abgeleitet werden.The invention is shown in the figure, this figure shows a Rohluftrohr 10 with a funnel-shaped inlet 11 , The raw air tube consists of a woven sheep wool tube 12 , this is at its ends with the other parts via fasteners 13 . 14 connected accordingly. The sheep's wool hose 12 goes over into a filter housing 15 in which there is a filter element 16 located. Above the filter element, the purified air is supplied to an internal combustion engine, not shown here. If the sucked raw air contains moisture or water droplets, this moisture or water droplets are absorbed by the wall and can be discharged to the outside.
