Description
Die Erfindung bezieht sich auf einen Zylinderkopf mit einer Vorrichtung zur Kontaktierung eines Motorsteuergerätes mit Stromverbrauchern, insbesondere Aktuatoren einer elektromagnetischen Ventilsteuerung, von Brennkraftmaschinen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a cylinder head with a device for contacting an engine control unit with power consumers, in particular actuators of an electromagnetic valve control, of internal combustion engines according to the preamble of patent claim 1.
Aus der DE 42 25 329 A1 ist eine Vorrichtung zur Kontaktierung eines Motorsteuergerätes mit Aktuatoren einer elektromagnetischen Ventilsteuerung einer Brennkraftmaschine bekannt. Die Brennkraftmaschine weist einen Zylinderkopf auf in dem Gaswechselventile angeordnet sind, die durch die elektromagnetischen Aktuatoren betätigt werden, wobei der Zylinderkopf durch eine Zylinderkopfhaube abgedeckt ist. Die Aktuatoren umfassen Öffnungs- und Schließmagneten, deren Ansteuerung durch das Motorsteuergerät erfolgt. Dazu weist jeder Aktuator ein Kabel auf, das ausgehend vom jeweiligen Aktuator innerhalb der Zylinderkopfhaube zu einer Ausnehmung in der Zylinderkopfhaube geführt wird, durch die das Kabel zur Anbindung an das Motorsteuergerät anschließend durchgesteckt wird.From DE 42 25 329 A1 discloses a device for contacting an engine control unit with actuators of an electromagnetic valve control of an internal combustion engine is known. The internal combustion engine has a cylinder head in which gas exchange valves are actuated, which are actuated by the electromagnetic actuators, wherein the cylinder head is covered by a cylinder head cover.

For this purpose, each actuator has a cable, which is guided starting from the respective actuator within the cylinder head cover to a recess in the cylinder head cover, through which the cable is then inserted for connection to the engine control unit.
Ein Nachteil der Vorrichtung liegt darin, daß beim Aufsetzen der Zylinderkopfhaube Quetschungen der in der Zylinderkopfhaube lose geführten Kabel möglich sein können. Ein weiterer Nachteil der Vorrichtung liegt in den Dichtigkeitsproblemen, da die Zylinderkopfhaube durch die Ausnehmungen für die Kabel potentielle Leckstellen aufweist. Im übrigen muß die Zylinderkopfhaube durch die innerhalb der Zylinderkopfhaube angeordneten Kabel ausreichend dimensioniert sein, so daß alle für die Aktuatoren benötigten Kabel ungehindert ihren Platz finden.A disadvantage of the device is that when placing the cylinder head cover bruising the loose in the cylinder head cover cables can be possible. Another disadvantage of the device is the leakage problems, since the cylinder head cover has potential leaks through the recesses for the cables. Moreover, the cylinder head cover must be arranged by the cable arranged inside the cylinder head cover be sufficiently dimensioned so that all cables needed for the actuators find their place unhindered.

Der Zylinderkopf ist durch eine Zylinderkopfhaube abdeckbar. Um eine Kontaktierung der Aktuatoren mit einem Motorsteuergerät der Brennkraftmaschine zu ermöglichen, sind elektrische Bauteile in die Zylinderkopfhaube integriert. Beim Aufsetzen der Zylinderkopfhaube erfolgt die Kontaktierung von Motorsteuergerät und Aktuatoren.EP 0 798 450 A1 shows an internal combustion engine with a cylinder head, in which gas exchange valves are arranged, which are actuated by electromagnetic actuators. The cylinder head can be covered by a cylinder head cover. In order to enable a contacting of the actuators with an engine control unit of the internal combustion engine, electrical components are integrated in the cylinder head cover. When placing the cylinder head cover contacting the engine control unit and actuators is done.
Aus der DE 197 19 299 C1 ist ein Zylinderkopf mit einer Vorrichtung zur Kontaktierung eines Motorsteuergerätes mit Aktuatoren einer elektromagnetischen Ventilsteuerung einer Brennkraftmaschine bekannt. Die Aktuatoren sind auf Trägerplatten vormontiert, welche bei der Montage der Brennkraftmaschine über Befestigungsvorrichtungen an dem Zylinderkopf oder an einem angrenzenden Bauteil befestigt werden. In den Trägerplatten sind Leiterbahnen und/oder Leistungsendstufen für die Aktuatoren integriert.From DE 197 19 299 C1 a cylinder head with a device for contacting an engine control unit with actuators of an electromagnetic valve control of an internal combustion engine is known. The actuators are preassembled on support plates, which are fastened during mounting of the internal combustion engine via fastening devices on the cylinder head or on an adjacent component. In the carrier plates conductor tracks and / or power amplifiers are integrated for the actuators.
Die EP 0 869 261 A1 zeigt einen gattungsgemässen Zylinderkopf einer Brennkraftmaschine mit Gaswechselventilen, welche durch jeweils in einem Gehäuse angeordnete elektromagnetische Aktuatoren betätigbar sind. Zur Kontaktierung der Aktuatoren mit einem Motorsteuergerät der Brennkraftmaschine weist der Zylinderkopf seitlich eine Kontaktierungsvorrichtung auf, wobei ausgehend von den Elektromagneten im Aktuatorgehäuse Leiterbahnen nach aussen verlaufen, die in einer auf dem Zylinderkopf angeordneten Steckeraufnahme enden.EP 0 869 261 A1 shows a generic cylinder head of an internal combustion engine with gas exchange valves, which can be actuated by respective electromagnetic actuators arranged in a housing. For contacting the actuators with an engine control unit of the internal combustion engine, the cylinder head laterally on a contacting device, starting from the electromagnets in the actuator housing tracks extend to the outside, which terminate in a arranged on the cylinder head connector receptacle.
Zum allgemeinen technischen Hintergrund wird noch auf eine ältere Anmeldung DE 197 56 095.4 verwiesen.For the general technical background, reference is made to an earlier application DE 197 56 095.4.
Es ist die Aufgabe der Erfindung einen Zylinderkopf mit einer Vorrichtung zur Kontaktierung eines Motorsteuergerätes einer Brennkraftmaschine derart auszubilden, daß bei gleichzeitiger Bauraumoptimierung eine Montageverbessserung ermöglicht ist.It is the object of the invention to form a cylinder head with a device for contacting an engine control unit of an internal combustion engine such that an assembly improvement is made possible with simultaneous space optimization.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 gegebenen Merkmale gelöst.This object is achieved by the given in the characterizing part of claim 1 features.
Ein wesentlicher Vorteil des erfindungsgemässen Zylinderkopfes liegt in der Optimierung der Montage und des Bauraumbedarfs. Die Integration der zur Kontaktierung benötigten elektrischen Bauteile, d.h. der Leistungsendstufen, der Aufnahmen für die stromverbraucherseitigen Stecker, und der die Leitungsendstufen und die Aufnahmen verbindenden Leitungen, in das Rahmenteil des Zylinderkopfes, bedeutet eine deutliche Erleichterung bei der Montage, weil vor dem Aufsetzen der Zylinderkopfhaube auf den Zylinderkopf alle Stromverbraucher insbesondere Aktuatoren mit dem Motorsteuergerät verbunden werden können, ohne daß beispielsweise Kabel durch die Zylinderkopfhaube durchgeführt werden müssen. Bei der Montage werden lediglich die Stecker der stromverbraucherseitigen Leitungen in die rahmenseitigen Steckeraufnahmen eingesteckt, wobei das Rahmenteil selbst über nur ein Kabel mit dem Motorsteuergerät verbunden ist. Vor dem Aufsetzen der Zylinderkopfhaube ist nunmehr lediglich zu prüfen, ob ein Kabel ohne Kontakt ist oder gequetscht wurde.An essential advantage of the cylinder head according to the invention lies in the optimization of the assembly and the space requirement. The integration of the electrical components required for contacting, i. the power output stages, the recordings for the stromverbraucherseitigen plug, and connecting the line power amplifiers and the receptacles lines in the frame part of the cylinder head, means a significant ease of assembly, because before putting the cylinder head cover on the cylinder head all power consumers in particular actuators with the engine control unit can be connected without, for example, cables must be performed through the cylinder head cover. During assembly, only the plug of the power consumers-side lines are plugged into the frame-side plug receptacles, wherein the frame part itself is connected via only one cable to the engine control unit. Before putting the cylinder head cover is now only to check whether a cable is without contact or was squeezed.
Zusätzlich werden durch das Rahmenteil potentielle Leckstellen in einer Zylinderkopfhaube vermieden, die beim Durchführen von Kabeln durch Ausnehmungen der Zylinderkopfhaube möglich wären, da die Stecker der Stromverbraucher nurmehr in die Steckeraufnahmen des Rahmenteiles eingesteckt werden müssen und die Stromverbraucher über ein vom Rahmenteil ausgehendes, zentrales Kabel mit dem Motorsteuergerät verbunden sind. Im übrigen ist durch die Integration der elektrischen Bauteile in das Rahmenteil eine Optimierung des Bauraumes erreicht. Die in das Rahmenteil integrierten elektrischen Bauteile umfassen sämtliche zur Kontaktierung von Stromverbrauchern mit dem Motorsteuergerät notwendigen Elemente, wie Leistungsendstufen, Steckeraufnahmen und Leitungen zur Verbindung von Leistungsendstufen und Steckeraufnahmen, wodurch nurmehr die stromverbraucherseitigen Leitungen mit Steckern innerhalb des Ventiltriebraumes zu den Steckeraufnahmen geführt werden müssen. Durch diese Reduzierung der Bauteilezahl ist eine kompakte Anordnung der Vorrichtung möglich.In addition, potential leaks in a cylinder head cover are avoided by the frame part, which would be possible when passing through cables through recesses of the cylinder head cover, since the plug of the power consumers only have to be plugged into the plug receptacles of the frame part and the power consumers via an outgoing from the frame part, central cable are connected to the engine control unit. Moreover, an optimization of the installation space is achieved by the integration of the electrical components in the frame part. The integrated into the frame electrical components include all necessary for contacting power consumers with the engine control unit elements, such as power amplifiers, plug receptacles and lines for connecting power amplifiers and plug receptacles, which only the power consumers side lines must be performed with plugs within the valve train space to the plug receptacles. By this reduction in the number of components, a compact arrangement of the device is possible.
Durch Einbringen einer dem Zylinderkopf zugewandten und/oder eine der Zylinderkopfhaube zugewandten Dichtleiste entfällt eine separate Haubendichtung. Dadurch, daß die Kontaktierung über das Rahmenteil erfolgt und keine Leitungen mehr durch die Zylinderkopfhaube nach außen geführt werden und eine Dichtleiste zwischen Rahmenteil und Zylinderkopfhaube vorgesehen ist, wird eine schwingungs- bzw. akkustische Entkoppelung der Zylinderkopfhaube erreicht.By introducing a cylinder head facing and / or the cylinder head cover facing sealing strip eliminates a separate hood seal. Characterized in that the contacting takes place via the frame part and no more lines are passed through the cylinder head cover to the outside and a sealing strip between the frame part and the cylinder head cover is provided, a vibration or acoustic decoupling of the cylinder head cover is achieved.

- Fig. 1
- in einem ersten Ausführungsbeispiel eine Vorrichtung zur Kontaktierung eines Motorsteuergerätes mit Zündspulen und Aktuatoren einer elektromagnetischen Ventilsteuerung einer Brennkraftmaschine mittels elektrischer Bauteile, welche vollständig in ein auf einen Zylinderkopf der Brennkraftmaschine aufgesetztes Rahmenteil integriert sind und

Fig. 1 zeigt in einem ersten Ausführungsbeispiel eine Vorrichtung zur Kontaktierung eines hier nicht dargestellten Motorsteuergerätes mit Stromverbrauchern einer mehrzylindrigen Brennkraftmaschine, bei denen es sich insbesondere um unten näher beschriebene Aktuatoren 1 einer elektromagnetischen Ventilsteuerung sowie um Zündspulen 2 handelt. Die hier nicht näher dargestellte, dreizylindrige Brennkraftmaschine weist einen Zylinderkopf 3 auf, der aus drei Gehäuseteilen 3a, 3b besteht, wobei das erste Gehäuseteil 3a den eigentlichen Zylinderkopf, das zweite Gehäuseteil 3b ein an den Zylinderkopf angeflanschtes Rahmenteil und das dritte, hier nicht sichtbare Gehäuseteil eine auf das Rahmenteil 3b aufsetzbare Zylinderkopfhaube ausbildet.Fig. 1 shows in a first embodiment, a device for contacting an engine control unit, not shown here with power consumers of a multi-cylinder internal combustion engine, which is in particular described below in more detail actuators 1 of an electromagnetic valve control and ignition coils 2. The not shown here, three-cylinder internal combustion engine has a cylinder head 3, which consists of three housing parts 3a, 3b, wherein the first housing part 3a the actual cylinder head, the second housing part 3b a flanged to the cylinder head frame part and the third, not visible here housing part a cylinder head cover can be placed on the frame part 3b.
Im Zylinderkopf 3 sind pro Zylinder eine Zündspule 2 und vier Gaswechselventile 4 (s. Fig. 2) gelagert, welche entsprechende, nicht sichtbare Gaswechselkanäle steuern und über jeweils einen ebenfalls im Zylinderkopf 3 gelagerten Aktuator 1 betätigt werden, wobei die Gaswechselventile 4 im wesentlichen im Bereich des ersten Gehäuseteiles, d.h. des Zylinderkopfes 3a und die Zündspule 2 sowie die Aktuatoren 1 im wesentlichen im Bereich des angeflanschten, einen Ventiltriebraum ausbildenden Rahmenteils 3b angeordnet sind. Auf das Rahmenteil 3b kann das dritte Gehäuseteil des Zylinderkopfes, die Zylinderkopfhaube, aufgesetzt werden.In the cylinder head 3 per cylinder an ignition coil 2 and four gas exchange valves 4 (see Fig. 2) are stored, which control corresponding non-visible gas exchange channels and are actuated via a likewise mounted in the cylinder head 3 actuator 1, wherein the gas exchange valves 4 substantially in Area of the first housing part, ie the cylinder head 3a and the ignition coil 2 and the actuators 1 are arranged substantially in the region of the flanged, a valve train space forming frame part 3b. On the frame part 3b, the third housing part of the cylinder head, the cylinder head cover, can be placed.
Jeder Aktuator 1 weist einen Wegsensor 5 zur Erfassung einer Position und/oder Bewegung des Gaswechselventils 4 und zwei elektrisch angesteuerte Schaltmagneten 6, 7 auf, d.h. einen Schließmagneten 6 und einen Öffnungsmagneten 7, zwischen deren Polflächen 8, 9 ein mit dem Gaswechselventil 4 verbundener Anker 10 koaxial zu der Ventilachse 11 (s. Fig. 2) verschiebbar angeordnet ist. Ein hier nicht sichtbarer Federmechanismus, der aus zwei vorgespannten Druckfedern besteht, bildet mit dem Gaswechselventil 4 einen Feder-Masse-Schwinger, dessen Ruhelage zwischen den beiden Ventilendstellungen, d.h. zwischen Offenstellung und Schließstellung des Gaswechselventils 4 liegt.Each actuator 1 has a displacement sensor 5 for detecting a position and / or movement of the gas exchange valve 4 and two electrically controlled switching magnets 6, 7, ie a closing magnet 6 and an opening magnet 7, between the pole faces 8, 9 connected to the gas exchange valve 4 anchor 10 coaxial with the valve axis 11 (see Fig. 2) is slidably disposed. A not visible here spring mechanism, the consists of two prestressed compression springs, forms with the gas exchange valve 4, a spring-mass oscillator, the rest position between the two valve end positions, ie between the open position and closed position of the gas exchange valve 4 is located.
Aus dieser Ruhelage wird der Ventilbetrieb dadurch gestartet, daß der Anker 10 vom Schließmagneten 6 oder Öffnungsmagneten 7 gegen die elastische Rückstellkraft des Federmechanismus in Richtung der zugehörigen Endstellung angezogen wird. Anschließend wird das Gaswechselventil 4 abwechselnd dadurch geöffnet und geschlossen, daß die Bestromung des momentan haltenden Schaltmagneten 6, 7 abgeschaltet wird, wodurch das Gaswechselventil 4 vom Federmechanismus aus der bisherigen Endstellung heraus zunächst bis zum Erreichen der Ruhelage beschleunigt wird. Das sich auf diese Weise über die Ruhelage hinaus bewegende Gaswechselventil 4 wird dann vom gegenüberliegenden Schaltmagneten 6, 7 gegen die elastische Rückstellkraft des Federmechanismus gefangen, wozu der Schaltmagnet 6, 7 mit einem sogenannten Fangstrom beaufschlagt wird.From this rest position of the valve operation is started by that the armature 10 is attracted by the closing magnet 6 or opening magnet 7 against the elastic restoring force of the spring mechanism in the direction of the associated end position. Subsequently, the gas exchange valve 4 is alternately opened and closed, that the energization of the momentarily holding switching magnet 6, 7 is turned off, whereby the gas exchange valve 4 is accelerated by the spring mechanism from the previous end position initially until reaching the rest position. The gas exchange valve 4 which moves in this way beyond the rest position is then caught by the opposite switching magnet 6, 7 against the elastic restoring force of the spring mechanism, for which purpose the switching magnet 6, 7 is subjected to a so-called catch current.
Jedem Zylinder ist eine Leistungsendstufe 12 zugeordnet, welche die aus vier Aktuatoren 1 nebst vier Wegsensoren 5 und einer Zündspule 2 bestehende Verbrauchergruppe ansteuert. Die Leistungsendstufen 12 nebst zugehörigen Aufnahmen für aktuatorseitige 13, 14 und zündspulenseitige Stecker 15 sind in das Rahmenteil 3b integriert und entweder einzeln oder zentral über ein nicht dargestelltes Kabel vom Rahmenteil 3b aus mit dem Motorsteuergerät verbunden.Each cylinder is assigned a power output stage 12, which controls the four actuators 1 together with four displacement sensors 5 and an ignition coil 2 existing consumer group.

Zur Stromversorgung eines Aktuators 4 mit einem zugehörigen Wegsensor 5 werden sieben Leitungen, die in zwei Stecker 13, 14 münden, benötigt. Drei Leitungen 17 werden für den Wegsensor 5 benötigt und vier Leitungen 18 sind für die Schaltmagnete 6, 7 vorgesehen, wobei die Leitungen 17 des Wegsensors 5 in einen Stecker 13 und die Leitungen 18 der Schaltmagnete 6, 7 des Aktuators 1 ebenfalls in einen Stecker 14 münden. Zur Stromversorgung der Zündspule 2 ist eine Leitung 19 mit einem Stecker 15 vorgesehen, wobei die Aufnahme für den zündspulenseitigen Stecker 15 ebenfalls in das Rahmenteil 3b integriert ist.To power an actuator 4 with an associated displacement sensor 5 seven lines that open into two plugs 13, 14, are required. Three lines 17 are needed for the displacement sensor 5 and four lines 18 are provided for the solenoids 6, 7, wherein the lines 17 of the displacement sensor 5 in a plug 13 and the lines 18 of the solenoids 6, 7 of the actuator 1 also in a plug 14th lead. To power the ignition coil 2 is a line 19 with a plug 15 is provided, wherein the receptacle for the ignition coil side plug 15 is also integrated into the frame part 3b.
