Description

Die Erfindung bezieht sich auf eine Brennkraftmaschine mit luftgekühltem Auspuffrohr.The invention relates to an internal combustion engine with air-cooled Exhaust pipe.

Bei Brennikraftmaschinen erwärmt sich das Auspuffrohr sehr oft bis zur Rotglut, eine Erscheinung, die zu Unglücksfällen führen kann, wenn die Brennkraftmaschine an Orten in Betrieb steht, an denen die Luft -zündfähige Bestandteile, beispielsweise Kohlenstaub oder Gas enthält. Hingewiesen sei beispielsweise auf,die Explosionsgefahr, die mit der Verwendung einer solchen Brennkraftmaschine in Erdölgebieten verbunden ist, in denen sich bei einem zufälligen Gasausbruch das Gas-Luft-Gemisch an dem glühenden Auspuffrohr entzünden könnte. Besonders groß ist die Explosionsgefahr bei luftgekühlten Brennkraftmaschinen, bei denen das Gas-Luft-Gemisch vom Kühlgehäuse erfaßt, an den Kühlrippen des Motors entlang geführt und hierbei vorgewärmt wird. Diese bei den bekannten Brennkraftmaschinen mit luftgekühltem Auspuffrohr beobachteten und die Verwendungsmöglichkeit dieser Maschinen stark einschränkenden Mängel sind bei der erfindungsgemäßen Brenukraftmasc'hinedadurch behoben, daß das Auspuffrohr insbesondere in Maschinennähe mit Abstand von einem flammensperrenden, luftdurchlässigen Mantel umgeben ist. Die Wirkung dieses Mantels beruht auf der bekannten physikalischen Erscheinung, wonach es einer Flamme nicht möglich ist, einen sie beschneidenden Drahtgazekäfig zu durchdringen. Bei der erfindungsgemäßen Bren.nikraftmaschine kann sich gegebenenfalls wohl das durch den Mantel zum glühenden Auspuffrohr vordringende Gas an dem Rohr entzünden, doch bleibt die Flamme innerhalb des von Rohr und Mantel gebildeten Raumes. Es versteht sich im Sinne der Erfindung von selbst, daß der Schutz entlang .der Auspuffleitung so weit ausgedehnt werden muB, wie die Erwärmung des Auspuffrohres dies wünschenswert erscheinen läßt. In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt.In internal combustion engines, the exhaust pipe very often heats up to red heat, a phenomenon that can lead to accidents when the internal combustion engine is in operation in places where the air -flammable components, for example Contains coal dust or gas. It should be pointed out, for example, the risk of explosion, associated with the use of such an internal combustion engine in oil fields is, in which, in the event of a random gas outbreak, the gas-air mixture at the could ignite a glowing exhaust pipe. The risk of explosion is particularly great in air-cooled internal combustion engines, in which the gas-air mixture from the cooling housing detected, guided along the cooling fins of the engine and preheated in the process. This observed in the known internal combustion engines with air-cooled exhaust pipes and the ability to use these machines are severely limiting deficiencies solved in the Brenukraftmasc'hine according to the invention that the exhaust pipe especially near the machine at a distance from a flame-blocking, air-permeable Coat is surrounded. The effect of this coat is based on the well-known physical Appearance according to which it is not possible for a flame to circumcise one Penetrate wire gauze cage. In the Bren.nikraftmaschine according to the invention can possibly the one penetrating through the jacket to the glowing exhaust pipe Ignite the gas on the tube, but the flame remains within that of the tube and jacket formed space. It goes without saying in the context of the invention that the protection must be expanded along the exhaust pipe as far as the heating of the Exhaust pipe makes this appear desirable. In the drawing are two exemplary embodiments of the invention shown.

Abb. i zeigt die Anwendung der Erfindung bei einem glatten Auspuffrohr; Abb.2 zeigt die erfindungsgemäße Umkleidung eines mit Kühlrippen versehenen Auspuffrohres.; Abb. 3 zeigt einen Schnitt 111-11I des Auspuffrohres nach Abb. 2.Fig. I shows the application of the invention to a smooth exhaust pipe; Fig.2 shows the casing according to the invention of an exhaust pipe provided with cooling fins .; Fig. 3 shows a section 111-11I of the exhaust pipe according to Fig. 2.

Das in A'bb. i im Längsschnitt gezeichnete Auspuffrohr i ist an eine nicht gezeichnete Brennkraftmaschine unter Zwischenschaltung eines, einen Flammenaustritt aus -dem Rohr verhindernden Isolierringes 8 angeschlossen und mit dem Abstand a von einem ebenfalls im Längsschnitt gezeichneten" mit Durchtrittsöffnungen 2 versehenen Mantel 3 umgeben. Die Durchtrittsöffnungen 2 in dem Mantel 3 sind so bemessen, daß die Kühlung des Auspuffrohres nur wenig Ibeeinträchtigt wird, eine sich in. dem Ringraum .I evtl. bildende Flamme jedoch innerhalb dieses Raumes verbleibt.That in A'bb. i exhaust pipe i drawn in longitudinal section is connected to a Internal combustion engine (not shown) with the interposition of a flame outlet connected from the pipe preventing insulating ring 8 and with the distance a of a "provided with passage openings 2" also drawn in longitudinal section Coat 3 surrounded. The passage openings 2 in the jacket 3 are dimensioned so that the cooling of the exhaust pipe is only slightly impaired Annular space .I possibly forming flame, however, remains within this space.

Abb. 2 zeigt ein mit Längskühlrippen 5 verschenes Auspuffrohr 6 im Längsschnitt. Diese Längsrippen 5 dienen dein Schutzmantel 7 als Träger.Fig. 2 shows an exhaust pipe 6 im with longitudinal cooling fins 5 Longitudinal section. These longitudinal ribs 5 serve your protective jacket 7 as a carrier.

Abb.3 stellt einen Querschnitt 111-III des in A@bb. 2 gezeigten Auspuffrohres dar.Fig.3 shows a cross section III-III of the in A @ bb. 2 exhaust pipe shown represent.
