Abstract

The engine has two rows of cylinders (3, 4) arranged at right angles to each other in the form of a V. The pistons (5, 6) in both rows drive the same crankshaft (10) through connecting rods (7, 8). The engine is air cooled and the cylinders have ribs on their outside surfaces for this purpose. The fuel injection pump (25) is contained in the space (22) between the branches of the V. Other auxiliary equipment can also be accommodated in this space. The space (22) between the branches of the V is closed by a cover plate (23). The underside of the plate carries sound absorbing material (24) which significantly reduces the noise emitted to the surrounding by the engine.

HubkolbenbrennkraftmaschineReciprocating internal combustion engine

Die Erfindung betrifft eine Hubkolbenbrennkraftmaschine, insbesondere luftgekühlte Hubkolbenbrennkraftmaschine, mit in V-Form angeordneten Zylinderreihen, wobei der von den Zylinderreihen gebildete V-förmige Raum nach oben mit einem Deckel verschlossen ist.The invention relates to a reciprocating internal combustion engine, in particular air-cooled reciprocating internal combustion engine, with rows of cylinders arranged in a V shape, the V-shaped one formed by the rows of cylinders The space at the top is closed with a lid.

Um die Geräuschabstrahlung von Brennkraftmaschinen zu vermindern, ist es bekannt, die Außenwände der Brennkraftmaschine mit schwingungsdämpfendem Material zu beschichten. Das Aufbringen solcher Schichten ist zeitraubend, schwierig und teuer. Ferner behindert der Belag die Wärmeabgabe des Gehäuses.To reduce the noise emitted by internal combustion engines, it is known, the outer walls of the internal combustion engine with vibration damping To coat material. The application of such layers is time consuming, difficult and expensive. Further handicapped the coating the heat dissipation of the housing.

Ferner ist es bekannt, die Oberfläche von Brennkraftmaschinen teilweise abzuschirmen, und zwar in Bereichen mit besonders starker Geräuschabstrahlung. Solche Maßnahmen sind aufwendig, haben aber häufig nur eine sehr beschränkte Wirkung.It is also known to partially cover the surface of internal combustion engines shield, in areas with particularly strong noise emissions. Such measures are complex, but often only have a very limited effect.

Der Erfindung liegt die Aufgabe zugrunde, mit möglichst wenig Mehraufwand die Geräuschabstrahlung der Brennkraftmaschine merklich zu vermindern. Diese Aufgabe wird bei einer Hubkolbenbrennkraftmaschine der eingangs beschriebenen Art dadurch gelöst, daß die Innenseite des V-Deckels mit einer schalldämpfenden Beschichtung versehen ist.The invention is based on the object with as little additional effort as possible the noise emitted by the internal combustion engine noticeably increases Reduce. This task is performed in a reciprocating internal combustion engine of the type described in the introduction in that the inside of the V-cover is provided with a sound-absorbing coating is.

Durch die erfindungsgemäße Maßnahme ergibt sich eine meßbare Geräuschabsenkung. Diese beruht darauf, daß die Beschichtung an der Innenseite des Deckels die Geräusche von der Brennkraftmaschine und von den Hilfsaggregaten im V-Raum dämpft und SchallreflektionenThe measure according to the invention results in a measurable noise reduction. This is based on the fact that the coating on the inside of the cover absorbs the noise from the internal combustion engine and from the auxiliary units in the V-room attenuates and sound reflections

durch den Deckel weitgehend vermieden werden, so daß die durch Öffnungen am V-förmigen Raum austretenden Geräusche stark reduziert sind. Dies ist besonders bei luftgekühlten Brennkraftmaschinen der Fall, bei denen größere Öffnungen am Kühlluftein- und -austritt vorhanden sind. Die erfindungsgemäße Maßnahme bedeutet zudem kaum baulichen Mehraufwand, da zumindest bei luftgekühlten Hubkolbenbrennkraftmaschinen mit stirnseitig angeordnetem Axialgebläse der oberhalb des V-förmigen Raumes angeordnete Deckel ohnehin vorhanden ist.can be largely avoided by the cover, so that the noises emerging through openings in the V-shaped space are greatly reduced are. This is particularly the case with air-cooled internal combustion engines, in which larger openings at the cooling air inlet and exit are present. The measure according to the invention also means hardly any additional structural effort, since at least with air-cooled Reciprocating internal combustion engines with a Axial fan of the cover arranged above the V-shaped space is already present.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. An exemplary embodiment of the invention is shown in the drawing.

Die Abbildung zeigt einen Querschnitt durch eine erfindungsgemäße Hubkolbenbrennkraftmaschine.The figure shows a cross section through a reciprocating internal combustion engine according to the invention.

Die dargestellte Hubkolbenbrennkraftmaschine weist zwei Zylinderreihen 1 und 2 mit luftgekühlten Zylindern 3 und 4 auf, in denen Kolben 5 und 6 axial verschiebbar angeordnet sind. An diesen sind Pleuelstangen 7 und 8 angelenkt, die auf einer im Kurbelgehäuse gelagerten Kurbelwelle 10 gelagert sind. Mit 11 ist eine am Kurbelgehäuse 9 angeflanschte Ölwanne bezeichnet, die einen Ölsumpf bildet, in den ein Saugrohr 12 einer nicht näher dargestellten Schmierölpumpe hineinragt.The reciprocating internal combustion engine shown has two rows of cylinders 1 and 2 with air-cooled cylinders 3 and 4, in which pistons 5 and 6 are arranged to be axially displaceable. At these are Connecting rods 7 and 8 articulated, which are mounted on a crankshaft 10 mounted in the crankcase. At 11 there is one on the crankcase 9 denotes flanged oil pan, which has an oil sump forms, into which a suction pipe 12 of a lubricating oil pump, not shown, protrudes.

Die Zylinder 3 und 4 sind mittels Zylinderköpfen 13 und 14 verschlossen, in denen Einspritzventile 15 und Gaswechselventile 16 vorgesehen sind. Letztere beherrschen Gaswechselkanäle 17, die sich an Saugleitungen 18 und 19 und Abgasleitungen 20 und 21 anschließen. The cylinders 3 and 4 are closed by means of cylinder heads 13 and 14, in which injection valves 15 and gas exchange valves 16 are provided. The latter dominate gas exchange channels 17, the connect to suction lines 18 and 19 and exhaust lines 20 and 21.
