Definitions
- the invention relates to an intake system consisting of an intake manifold and an air collector for a self-igniting internal combustion engine with a crankcase in which a crankshaft is rotatably mounted, to which a piston is fastened by means of at least one connecting rod, which piston can be moved in a cylinder, and the Cylinder is covered by a cylinder head in which an injection nozzle is attached to each cylinder, which is connected to an injection pump via an injection line, and inlet channels and outlet channels for gas exchange valves are arranged in the cylinder head, each inlet channel interacting with an intake port.
- Such an intake system is known from DE-OS 38 04 063.
- This suction system has advantages over the prior art, which in particular consist in the fact that this air suction pipe can be produced as a die-cast part, which enables material-saving mass production.
- a disadvantage of the suction system is that several casting cores have to be put together to form the casting mold. This requires manufacturing and labor.
- the invention has for its object to reduce the manufacturing and workload for producing an intake system and further reduce the overall assembly effort on the internal combustion engine.
- the intake manifold is integrated in an adapter plate, which is designed as a separate component from the air collector, and in that the adapter plate has at least one device for fixing the position of each injection line.
- the execution of the suction system in separate components simplifies the manufacture or manufacture of the parts by the simpler molds, so that the basic disadvantage of an additional component is fully compensated.
- different temperature requirements can be taken into account by choosing different materials for the two components.
- Another important advantage is based on the fact that the adapter plate has at least one device for fixing the position of one injection line each. Appropriate design of the mold of the adapter plate fixes the position without additional costs.
- the position fixation can be used both in the case of an exposed injection line and also in the case of a partially exposed injection line which is partly covered by housing parts such as the cylinder head cover, the position fixation advantageously also representing the required housing implementation in the second application.
- the device is designed as a connecting element for a split injection line. This further simplifies the assembly and disassembly work, since the injection line parts are inevitably assembled correctly and without tension, particularly during assembly.
- the connecting element is arranged on the adapter plate so that it cannot rotate.
- slots are incorporated into the adapter plate, into which the connecting elements can be inserted. This represents an inexpensive training, since the manufacturing effort is very low.
- the openings can be sealed tightly by the housing parts.
- a channel is embedded in the adapter plate, which is arranged along the cylinder head in the area of the intake manifold.
- This channel is easy to manufacture due to the material accumulation in this area and can be used for a wide variety of functions. So it is conceivable to ensure a liquid for cooling or heating the intake manifold and consequently the incoming combustion air through the channel. On the other hand, it may be necessary to conduct a liquid or generally a medium from one internal combustion engine end to the other internal combustion engines. According to the invention, it is provided to manufacture the channel with a preferably circular cross section or as a free-cast channel, the open side being closed by the cylinder head wall.
- the channel preferably has outlets opening into the intake manifold and is connected on the inlet side to the crankcase ventilation system.
- effective crankcase ventilation with simultaneous lubrication of the inlet valves is guaranteed with simple means.
- This application will be used especially in naturally aspirated engines, but it is also conceivable to use it in supercharged engines if the pressure in the duct is higher than that of the support system.
- Intake ducts 1 of a cylinder head 2 open into a longitudinal side wall of the cylinder head 2.
- An intake system for the internal combustion engine which is in particular a self-igniting internal combustion engine, is arranged on this side wall.
- the intake system consists of an adapter plate 3 and an air collector 4.
- the air collector 4 is essentially designed as a trough-shaped cover which extends along the cylinder head 2 and is supported on the adapter plate 3.
- a circumferential seal 5 is embedded, vulcanized, glued or knotted into the adapter plate 3 in the area of the impinging air collector walls. The seal assumes both the sealing function of the adapter plate 3 to the cylinder head 2 and that of the air collector 4 to the adapter plate 3.
- the adapter plate 3 is fastened to the cylinder head by means of screws 6a and 6b (FIG. 2).
- the air collector 4 is fastened to the adapter plate 3 by means of fastening screws 7a, 7b.
- a sufficient number of screws 6a, 6b as well as fastening screws 7a, 7b are distributed along a multi-cylinder head 2.
- the screw heads of the fastening screws 7a, 7b are suitably sealed, for example, by a seal with respect to the air collector 4, so that no external air can enter or escape from the air collector 4 at these screw passages.
- the adapter plate 3 furthermore has intake manifold sections 8a, 8b which connect to the inlet channels 1 and ensure that the combustion air flows into the inlet channels 1 without loss.
- a channel 9 is machined, for example cast in, into the intake manifold section 8b and is connected on the inlet side to the crankcase ventilation system of the internal combustion engine.
- the channel 9 is designed as a cast channel (FIG. 5), the free side being covered by the cylinder head side wall.
- the channel 9 in the area of the inlet channels 1 has outlets 10 which for example, are drilled. If the channels are drilled completely, they are closed on the side facing away from the inlet channels 1 by sealing plugs 11.
- the adapter plate 3 is provided with slots 13 (FIG. 4) on the cylinder head cover side 12.
- Connecting elements 14 (FIG. 1) can be plugged into the slots 13 so that they cannot rotate.
- the connecting elements 14 form a passage for an injection line 15a, 15b from the valve chamber 16 covered by the cylinder head cover 12, in which the injection nozzle is arranged, to the injection pump arranged outside the internal combustion engine.
- the injection line 15b is fastened to the connecting element 14 by means of a union nut 17.

Abstract
Description
Die Erfindung betrifft ein aus Ansaugstutzen und einem Luftsammler bestehendes Ansaugsystem für eine selbstzündende Brennkraftmaschine mit einem Kurbelgehäuse, in dem eine Kurbelwelle drehbar gelagert ist, an der mittels zumindest eines Pleuels je ein Kolben befestigt ist, der in je einem Zylinder bewegbar ist, und wobei der Zylinder von einem Zylinderkopf abgedeckt ist, in dem je Zylinder eine Einspritzdüse befestigt ist, die über eine Einspritzleitung mit einer Einspritzpumpe verbunden ist, sowie Einlaßkanäle und Auslaßkanäle zu Gaswechselventilen in dem Zylinderkopf angeordnet sind, wobei jeder Einlaßkanal mit einem Ansaugstutzen zusammenwirkt.The invention relates to an intake system consisting of an intake manifold and an air collector for a self-igniting internal combustion engine with a crankcase in which a crankshaft is rotatably mounted, to which a piston is fastened by means of at least one connecting rod, which piston can be moved in a cylinder, and the Cylinder is covered by a cylinder head in which an injection nozzle is attached to each cylinder, which is connected to an injection pump via an injection line, and inlet channels and outlet channels for gas exchange valves are arranged in the cylinder head, each inlet channel interacting with an intake port.
Ein derartiges Ansaugsystem ist aus der DE-OS 38 04 063 bekannt. Dieses Ansaugsystem weist gegenüber dem Stand der Technik Vorteile auf, die insbesondere darin bestehen, daß dieses Luftansaugrohr als Druckgußteil hergestellt werden kann, wodurch eine materialsparende Massenfertigung möglich ist. Nachteilig an dem Ansaugsystem ist, daß mehrere Gußkerne zur Gußform zusammengesetzt werden müssen. Dies erfordert Fertigungs- und Arbeitsaufwand.Such an intake system is known from DE-OS 38 04 063. This suction system has advantages over the prior art, which in particular consist in the fact that this air suction pipe can be produced as a die-cast part, which enables material-saving mass production. A disadvantage of the suction system is that several casting cores have to be put together to form the casting mold. This requires manufacturing and labor.
Der Erfindung liegt die Aufgabe zugrunde, den Fertigungs- und Arbeitsaufwand zur Herstellung eines Ansaugsystems zu verringern und weiterhin den Montageaufwand insgesamt an der Brennkraftmaschine zu verringern.The invention has for its object to reduce the manufacturing and workload for producing an intake system and further reduce the overall assembly effort on the internal combustion engine.
Diese Aufgabe wird dadurch gelöst, daß der Ansaugstutzen in eine Adapterplatte integriert ist, die als von dem Luftsammler separates Bauteil ausgeführt ist, und daß die Adapterplatte zumindest eine Vorrichtung zur Lagefixierung je einer Einspritzleitung aufweist. Durch die Ausführung des Ansaugsystem in separaten Bauteilen wird die Fertigung beziehungsweise Herstellung der Teile durch die einfacheren Gußformen so weit vereinfacht, so daß der grundsätzliche Nachteil eines zusätzlichen Bauteils voll ausgeglichen wird. Zudem können durch die Wahl von gegebenenfalls unterschiedlichen Werkstoffen für die beiden Bauteile unterschiedliche Temperaturanforderungen berücksichtigt werden. Ein weiterer wesentlicher Vorteil ist darin begründet, daß die Adapterplatte zumindest eine Vorrichtung zur Lagefixierung je einer Einspritzleitung aufweist. Durch eine entsprechende Ausgestaltung der Gußform der Adapterplatte wird ohne Mehrkosten die Lagefixierung erreicht. Die Lagefixierung ist sowohl bei einer freiliegenden Einspritzleitung anwendbar, als auch bei einer teilweise freiliegenden und teilweise durch Gehäuseteile wie Zylinderkopfhaube verdeckten Einspritzleitung erforderlich, wobei im zweiten Anwendungsfall die Lagefixierung vorteilhaft gleichzeitig die erforderliche Gehäusedurchführung darstellt.This object is achieved in that the intake manifold is integrated in an adapter plate, which is designed as a separate component from the air collector, and in that the adapter plate has at least one device for fixing the position of each injection line. The execution of the suction system in separate components simplifies the manufacture or manufacture of the parts by the simpler molds, so that the basic disadvantage of an additional component is fully compensated. In addition, different temperature requirements can be taken into account by choosing different materials for the two components. Another important advantage is based on the fact that the adapter plate has at least one device for fixing the position of one injection line each. Appropriate design of the mold of the adapter plate fixes the position without additional costs. The position fixation can be used both in the case of an exposed injection line and also in the case of a partially exposed injection line which is partly covered by housing parts such as the cylinder head cover, the position fixation advantageously also representing the required housing implementation in the second application.
In Weiterbildung der Erfindung ist die Vorrichtung als Verbindungselement für eine geteilte Einspritzleitung ausgebildet. Damit wird der Montage- bzw. Demontageaufwand weiter vereinfacht, da die Einspritzleitungsteile insbesondere bei der Montage zwangsläufig richtig und ohne Verspannungen montiert werden.In a further development of the invention, the device is designed as a connecting element for a split injection line. This further simplifies the assembly and disassembly work, since the injection line parts are inevitably assembled correctly and without tension, particularly during assembly.
In Weiterbildung der Erfindung ist das Verbindungselement verdrehsicher an der Adapterplatte angeordnet. Dadurch wird zusätzlich zu der montageerleichternden Lagefixierung das Gegenhalten von Schraubschlüsseln bei Verschraubungsvorgängen überflüssig.In a further development of the invention, the connecting element is arranged on the adapter plate so that it cannot rotate. As a result, in addition to fixing the position, which makes installation easier, there is no need to hold wrenches in place during screwing operations.
Dazu sind in vorteilhafter Weiterbildung in die Adapterplatte Schlitze eingearbeitet, in die die Verbindungselemente einsteckbar sind. Dieses stellt eine günstige Ausbildung dar, da der Herstellungsaufwand sehr gering ist. Gleichzeitig kann beispielsweise bei einer U-förmigen Ausbildung der Schlitze und entsprechend angepaßten U-förmigen Verbindungselement ein dichtes Verschließen der Durchbrüche durch die Gehäuseteile erreicht werden.For this purpose, in an advantageous further development, slots are incorporated into the adapter plate, into which the connecting elements can be inserted. This represents an inexpensive training, since the manufacturing effort is very low. At the same time, for example, with a U-shaped design of the slots and correspondingly adapted U-shaped connecting element, the openings can be sealed tightly by the housing parts.
In weiterer Ausgestaltung der Erfindung ist in die Adapterplatte ein Kanal eingelassen, der entlang des Zylinderkopfes im Bereich der Ansaugstutzen angeordnet ist. Dieser Kanal ist durch die in diesem Bereich ohnehin vorhandene Materialanhäufung problemlos zu fertigen und kann für die verschiedensten Funktionen herangezogen werden. So ist es denkbar, durch den Kanal eine Flüssigkeit zum Kühlen oder Erwärmen der Ansaugstutzen und folglich somit der einströmenden Verbrennungsluft zu gewährleisten. Zum anderen kann es erforderlich sein, von einem Brennkraftmaschinenende zu den anderen Brennkraftmaschinen eine Flüssigkeit oder allgemein ein Medium zu leiten. Erfindungsgemäß ist vorgesehen, den Kanal mit vorzugsweise kreisförmigen Querschnitt zu fertigen oder als freigegossenen Kanal, wobei die offene Seite von der Zylinderkopfwand verschlossen wird.In a further embodiment of the invention, a channel is embedded in the adapter plate, which is arranged along the cylinder head in the area of the intake manifold. This channel is easy to manufacture due to the material accumulation in this area and can be used for a wide variety of functions. So it is conceivable to ensure a liquid for cooling or heating the intake manifold and consequently the incoming combustion air through the channel. On the other hand, it may be necessary to conduct a liquid or generally a medium from one internal combustion engine end to the other internal combustion engines. According to the invention, it is provided to manufacture the channel with a preferably circular cross section or as a free-cast channel, the open side being closed by the cylinder head wall.
Vorzugsweise weist der Kanal in die Ansaugstutzen mündende Austritte auf und ist eintrittsseitig mit dem Kurbelgehäuseentlüftungssystem verbunden. In dieser Ausgestaltung wird mit einfachen Mitteln eine wirkungsvolle Kurbelgehäuseentlüftung bei gleichzeitiger Schmierung der Einlaßventile (insbesondere der Ventilschäfte und der Sitzringe) gewährleistet. Dabei wird diese Anwendung insbesondere bei Saugmotoren zur Anwendung kommen, es ist aber auch denkbar, sie bei aufgeladenen Motoren anzuwenden, wenn der in dem Kanal herrschende Druck höher als der des Auflagdsystems ist.The channel preferably has outlets opening into the intake manifold and is connected on the inlet side to the crankcase ventilation system. In this configuration effective crankcase ventilation with simultaneous lubrication of the inlet valves (in particular the valve stems and the seat rings) is guaranteed with simple means. This application will be used especially in naturally aspirated engines, but it is also conceivable to use it in supercharged engines if the pressure in the duct is higher than that of the support system.
Weitere vorteilhafte Weiterbildungen der Erfindung sind der Zeichnungsbeschreibung zu entnehmen, in der ein in den Figuren dargestelltes Ausführungsbeispiel beschrieben ist.Further advantageous developments of the invention can be found in the drawing description, in which an exemplary embodiment shown in the figures is described.

An dieser Seitenwand ist ein Ansaugsystem für die Brennkraftmaschine, die insbesondere eine selbstzündende Brennkraftmaschine ist, angeordnet. Das Ansaugsystem besteht aus einer Adapterplatte 3 sowie einem Luftsammler 4. Der Luftsammler 4 ist im wesentlichen als wannenförmiger Deckel ausgebildet, der sich entlang des Zylinderkopfes 2 erstreckt und auf der Adapterplatte 3 abstützt. In die Adapterplatte 3 ist im Bereich der auftreffenden Luftsammlerwände eine umlaufende Dichtung 5 eingelassen, einvulkanisiert, eingeklebt oder eingeknüpft. Die Dichtung übernimmt sowohl die Dichtungsfunktion der Adapterplatte 3 zum Zylinderkopf 2 als auch die des Luftsammlers 4 zu der Adapterplatte 3.Intake
