Abstract

Fuel supply lines (4) in compact fuel injection engines are incorporated in an extruded components (3) in which the necessary lines are arranged parallel to one another. The components also contains supply and return lines for the cooling medium. Connecting apertures (5) runs transverse to the supply channels (4) and open out into connection, faces (6) running parallel to the channels. The feeder lines (7) are coupled to these faces. The extruded component forms part of the motor casing or the cooling air guide. The use of such an extruded component with channels for conveying fuel and cooling medium minimises the space requirements for such supply lines and facilitates the construction of a compact engine assembly.

Description

Kraftstoffleitungen Die Erfindung betrifft Kraftstoffleitungen für Elnspritz-Brennkraftmaschinen. Fuel Lines The invention relates to fuel lines for Injection internal combustion engines.

Bei kompakt gebauten Einspritz-Brennkraftmaschinen führt die Verlegung der zum Einspritzsystem gehörenden Leitungen häufig zu unübersichtlichen, störungsanfälligen und schwer zu montierenden sowie zu wartenden Anordnungen von Leitungen. Die Schwierigkeiten werden zudem größer, wenn neben der Kraftstoffzuleitung eine Rückleitung des überschüssigen Kraftstoffes, außerdem eine Leitung für den Leckkraftstoff sowie weitere Leitungen für die Kihlmittelzu- und ableitung vorgesehen werden müssen. Derartige Anordnungen erfordern einen großen Bauraum, insbesondere wenn zusätzliche Maßnahmen gegen Beschädigung und Undichtigkeiten der Leitungen getroffen werden müssen.In the case of compactly built injection internal combustion engines, the relocation leads the lines belonging to the injection system are often confusing and prone to failure and difficult-to-assemble and difficult-to-maintain arrangements of lines. Difficulties are also greater if there is a return line of the excess in addition to the fuel supply line Fuel, as well as a line for the leak fuel and other lines must be provided for the coolant supply and discharge. Such arrangements require a large installation space, especially if additional measures are taken to prevent damage and leaks in the lines must be met.

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln eine übersichtliche, betriebssichere, leicht montierbare und raumsparende Anordnung der Kraftstoffleitungen zu schaffen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in einem Strangpreßprofil alle für die Kraftstoffleitung erforderlichen Kanäle parallel verlaufend angeordnet sind. Durch die vielfäkige Gestaltungsmöglichkeit des Strangpreßprofils können die Leitungen, die nicht unbedingt an runde Kanalquerschnitte gebunden sind, optimal dem zur Verfügung stehenden Bauraum und ihrer Funktion angepaßt werden. Sie können als stabiler Leitungsblock einfach befestigt werden. Auch ergeben sie ein günstigeres Schwingungsverhalten.The invention is based on the object of using simple means clear, reliable, easy to assemble and space-saving To create arrangement of the fuel lines. This object is achieved according to the invention solved in that all required for the fuel line in an extruded profile Channels are arranged running parallel. Due to the wide range of design options of the extruded profile, the lines, which are not necessarily connected to round duct cross-sections are bound, optimally adapted to the available space and their function will. They can be easily attached as a stable line block. Also surrendered they have a more favorable vibration behavior.

In vorteilhafter Weise kann das Strangpreßprofil selbst Bestandteil der Motorverkleidung bzw. der Kühlluftführung sein und somit sich in die Gesamtgestaltung der Brennkraftmaschine harmonisch einfügen. Ferner sind Abzweigungen und Anschlüsse in einfacher Weise gemäß einer Ausgestaltung der Erfindung dadurch zu verwirklichen, daß quer zu den parallel verlaufenden Kanälen Anschlußbohrungen vorgesehen sind, die in parallel zu den Kanälen verlaufenden Anschlußflächen münden. Dadurch kann das Strangpreß profil eine gewisse Verteilerfunktion übernehmen, indem es die Betriebsmittel in die unmittelbare Nähe der Verbraucherstellen leitet und dort auf die einzelnen Verbraucher verteilt.The extruded profile itself can advantageously be part of it the engine cover or the cooling air duct and thus be part of the overall design the internal combustion engine harmoniously insert. There are also branches and connections to be realized in a simple manner according to an embodiment of the invention, that connection bores are provided transversely to the parallel channels, which open into connecting surfaces running parallel to the channels. This can the extrusion profile take on a certain distribution function by the Resources in the immediate vicinity of the consumer points and there on the individual Consumer distributed.

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

Abb. 2 zeigt eine mit II in Abbildung 1 gekennzeichnete Einzelheit.Fig. 2 shows a detail marked II in Fig. 1.

Die dargestellte Hubkolben-Brennkraftmaschine mit V-förmig angeordneten Zylinderreihen weist eine Verkleidung 2 auf, deren Bestandteil ein Strangpreßprofil 3 ist. Dieses weist parallel verlaufende Kanäle 4 auf, die zur Zu- und Rückführung des Kraftstoffes und des Kühlmittels dienen. Quer zu den Kanälen 4 verlaufen Anschlußbohrungen 5, die in parallel zu den Kanälen 4 verlaufenden Anschlußflächen 6 münden. An den Anschlußflächen 6 sind weiterführende Rohrleitungen 7 angeflanscht.The illustrated reciprocating internal combustion engine with a V-shaped arrangement Rows of cylinders has a cladding 2, part of which is an extruded profile 3 is. This has parallel channels 4 which are used for supply and return serve for fuel and coolant. Connection bores run transversely to the channels 4 5, which open into connection surfaces 6 running parallel to the channels 4. To the Connection surfaces 6 are flanged to further pipelines 7.
