Abstract
Description
Die Erfindung betrifft eine Hubkolbenbrennkraftmaschine, insbesondere einen Großdieselmotor mit wenigstens einem Abgasturbolader, dessen Ladeluftausgang mittels einer Verbindungsleitung mit einem nachgeordneten Ladeluftkühler verbunden ist, und dem Mittel zur Reduktion von Schallemissionen zugeordnet sind.The The invention relates to a reciprocating internal combustion engine, in particular a large diesel engine with at least one exhaust gas turbocharger whose charge air outlet means a connecting line connected to a downstream intercooler is assigned to the means for the reduction of acoustic emissions are.
Bei aufgeladenen Hubkolbenbrennkraftmaschinen werden durch den Verdichter des Turboladers Pulsationen erzeugt und in die Ladeluftleitung übertragen. Die dadurch entstehenden Geräusche werden durch das Gehäuse des Ladeluftkühlers verstärkt, das wie ein Resonanzboden wirkt.at charged reciprocating internal combustion engines are powered by the compressor generated by the turbocharger pulsations and transferred to the charge air line. The resulting noise will be through the housing of the intercooler strengthened that acts like a soundboard.
Lange wurde versucht, die Emission des im Abgasturbolader entstehenden Schalls durch eine Schallisolation besonders gefährdeter Elemente zu reduzieren. Dabei ist davon auszugehen, dass eine Schallisolation von Leitungen bzw. Gehäusen nur dann brauchbare Ergebnisse erbringen kann, wenn diese Isolation auf der ganzen Länge der Leitungen bzw. auf der ganzen Oberfläche der Gehäuse angebracht werden kann. Dies ist jedoch vielfach bereits aus baulichen Gründen nicht möglich. Die Schallisolation besteht nämlich aus einer vergleichsweise dicken Dämmmaterialschicht, die mit einem Blech ummantelt ist. Dies erfordert viel Bauraum, der oft nicht vorhanden ist. Außerdem erfordert die Anbringung einer Schallisolation einen vergleichsweise hohen Aufwand, da die gefährdeten Leitungen etc. in der Regel schlecht zugänglich sind. Ein weiterer, ganz besonderer Nachteil ist darin zu sehen, dass sich das Dämmmaterial bei hohen Temperaturen, die im Bereich seines Abgasturboladers auftreten, leicht zersetzen kann, so dass nach einer bestimmten Zeit die Isolationswirkung abnimmt.Long was trying to reduce the emission of the exhaust gas turbocharger To reduce sound by a sound insulation of particularly endangered elements. It can be assumed that a sound insulation of lines or housings can only provide useful results if this isolation on the whole length the lines or on the entire surface of the housing can be attached. However, this is often not already for structural reasons possible. The sound insulation is namely from a comparatively thick insulating material layer, which with a sheet metal is sheathed. This requires a lot of space, often not available. Furthermore the attachment of a sound insulation requires a comparatively high effort, as the endangered Lines etc. are usually poorly accessible. Another, very particular disadvantage is the fact that the insulating material at high temperatures that occur in the region of its exhaust gas turbocharger, can easily decompose, so that after a certain time the insulation effect decreases.

Der nach dem Helmholz-Prinzip arbeitende Schalldämpfer kann trotz kompakter Bauweise viel Schallenergie absorbieren. Im Bereich jedes Lochs des Lochblechs ergibt sich nämlich praktisch ein Feder-, Masse-, Schwingungssystem, indem die sich im Loch befindliche Fluidmasse bei einer Anregung durch eine Schallwelle schwingt, wobei das in der Kammer sich befindende Fluidvolumen als Feder wirkt. Aufgrund der starken Reibung, die sich an den Lochwänden, bei denen ein Lochanteil bezüglich des Lochbleches in einem Bereich von etwa 0,5 % bis 1,5 vorgesehen ist, ergibt, resultiert eine starke Dämpfung. Da der Schalldämpfer in radialer Richtung, d.h. Lotrecht zum Lotblech, vergleichsweise wenig Bauraum benötigt, ist in vorteilhafter Weise eine Anordnung des Schalldämpfers nicht nur im Bereich peripherer Leitungen und Gehäuse etc. möglich. Vielmehr ist auch ein Einbau direkt in den Abgasturbolader möglich.Of the according to the Helmholz principle working muffler can be more compact Construction absorb a lot of sound energy. In the area of every hole of the Perforated sheet results namely Virtually a spring, mass, vibration system by itself in the hole located fluid mass at an excitation by a sound wave vibrates, wherein the fluid volume in the chamber as Spring acts. Due to the strong friction that sticks to the hole walls, at which a hole proportion with respect of the perforated plate in a range of about 0.5% to 1.5 results in a strong damping. Since the muffler in radial direction, i. Lotrecht to the solder sheet, comparatively little Space required, is advantageously not an arrangement of the muffler only possible in the area of peripheral cables and housings etc. Rather, it is also a Installation directly into the turbocharger possible.

Als Material für das Absorptionselement hat sich offenporiger Schaumstoff bewährt. Auch werden bereits für diesen Zweck Mineralstoffe, bzw. glasartige Glasfaserverbindungen mit einem Silicatanteil verwendet.When Material for the absorption element has proven itself open-cell foam. Also be already for this purpose minerals, or glassy fiberglass compounds used with a silicate content.
Dieses Material ist sehr porös und hat somit den Nachteil, dass durch die hohe Strömungsgeschwindigkeit der Ladeluft es zu Austragungen dieses porösen Materials kommen kann, die sich in den feinen Kühlrippen des Ladeluftkühlers ablagern können. Zur notwendigen Reinigung ist dann ein aufwändiger Ladeluftkühlerausbau erforderlich und eine Reinigung in Säurebädern durchzuführen, was wiederum aufwändig und sehr unbeliebt ist.This Material is very porous and thus has the disadvantage that due to the high flow velocity the charge air can lead to discharges of this porous material, which are in the fine cooling fins of the intercooler can deposit. The necessary cleaning is then a complex intercooler removal required and perform a cleaning in acid baths, what again consuming and very unpopular.
Hiervon ausgehend ist es die Aufgabe der vorliegenden Erfindung, eine Anordnung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, dass einerseits eine einfache und kompakte Bauweise der Schallbekämpfungsmaßnahmen erhalten bleibt, ohne die Lösung mit einem Resonanzschalldämpfer verwenden zu müssen und andererseits dennoch auch eine hohe Dämpfungswirkung sowie eine lange Lebensdauer zu erreichen, jedoch ohne die oben bezeichneten Nachteile, insbesondere die Austragungen eines porösen Materials in Kauf zu nehmen.Of these, Starting from the object of the present invention, an arrangement mentioned above Kind with simple and inexpensive means to improve so that on the one hand a simple and compact design the sound-control measures is preserved without the solution a resonance muffler to use and on the other hand still a high damping effect and a long To achieve life, but without the disadvantages described above, in particular to accept the discharges of a porous material.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.These The object is achieved by the characterizing features of claim 1 solved.
Dadurch dass wenigstens in einem strömungsführenden Element des Abgasturboladers der Absorptionsschalldämpfer integriert ist, derart dass eine den zugeordneten Strömungskanal begrenzende , als akustisch durchlässiger Austragsschutz ausgebildete innere Rohrwandung vorgesehen ist, die von einem Aussenrohr mit radialem Abstand etwa koaxial umfasst wird, so dass mindestens eine Ringkammer ausgebildet wird, die mit einem Absorptionswerkstoff aus Aramidfasern (hergestellt aus poly-(Paraphenylen-Terephthalamid), auch Kevlar genannt, Markenname von DuPont) ausgefüllt ist, ist eine gute Schallabsorption im oberen Frequenzbereich ≥1 kHz gewährleistet.Thereby that at least in a flow-leading Integrated element of the exhaust gas turbocharger of the absorption silencer is such that a limiting the associated flow channel, as acoustically permeable Austragsschutz trained inner tube wall is provided by an outer tube with a radial distance is approximately coaxial, so that at least one annular chamber is formed, which with a Aramid fiber absorbent material (made of poly (paraphenylene terephthalamide), also called Kevlar, brand name of DuPont), Good sound absorption is ensured in the upper frequency range ≥1 kHz.
Aramidfaser haben etwa die gleiche Festigkeit wie Glasfaser (Dichte 1,44 g/cm3, Zugfestigkeit ca. 2.800 N/mm2), sind aber wesentlich zäher, sprich: Sie lassen sich wesentlich stärker dehnen bis zum Versagen. Sie sind organische Chemiefasern auf der Basis aromatischer Polyamide.Aramid fibers have about the same strength as glass fiber (density 1.44 g / cm 3 , tensile strength about 2,800 N / mm 2 ), but are much tougher, that is: they can be stretch significantly more until failure. They are organic chemical fibers based on aromatic polyamides.
Dieser Absorptionsschalldämpferwerkstoff hat eine hohe Resistenz gegenüber mechanischer Materialaustragung (z. Bsp. durch hohe Strömungsgeschwindigkeit). Durch Abrieb entstehen zwar Feinststaubpartikel, diese können aber z. Bsp. mittels Industriestaubsauger leicht beseitigt werden. Es sind keine Spezialmaschinen oder die unbeliebte Reinigung mittels Säurebädern mehr erforderlich.This Has absorption silencer material a high resistance to mechanical material discharge (eg due to high flow velocity). Although abrasion causes fine dust particles, they can z. For example, be easily removed by means of industrial vacuum cleaner. There are no special machines or unpopular cleaning with acid baths anymore required.
Desweiteren ist die Faser weitgehend unempfindlich gegenüber Chemikalien und schwer entflammbar, besitzt also eine Temperaturbeständigkeit (Verkohlung bzw. Pyrolyse erst oberhalb ca. 300°C), damit ist ein Aufschmelzen oder Verbacken des Dämmwerkstoffs ausgeschlossen, da normalerweise kein Abgasturbolader-Rohr die Temperatur von 250°C überschreitet.Furthermore the fiber is largely insensitive to chemicals and heavy flammable, so has a temperature resistance (charring or pyrolysis only above about 300 ° C), so is a melting or caking of the insulating material excluded, since usually no exhaust gas turbocharger tube exceeds the temperature of 250 ° C.
Ausserdem ist die Aramidfaser beständig (also langlebig) und bakteriell kaum abbaubar. Dies ist von unschätzbarem Wert im Falle des Auftretens von Kondenswasser.Moreover The aramid fiber is resistant (ie long-lived) and hardly biodegradable. This is priceless Value in case of condensation.
