In der Zeichnung sind 2 Ausführungsbeispiele der Erfindung dargestellt. Es zeigt:In the drawing, two exemplary embodiments of the invention are shown. It shows:

Fig. 1 eine schematische Darstellung eines Zylinderkopfes einer Einspritz-Brennkraftmaschine mit einer Saugleitungsanordnung und je einem gesondert angeordneten Leerlaufluft-Bypass und Warmlaufluftventil,1 shows a schematic representation of a cylinder head of an injection internal combustion engine with an intake line arrangement and a separately arranged idle air bypass and warm-up air valve,

Fig. 2 ein Warmlaufluftventil mit integriertem Leerlaufluft-Bypass und2 shows a warm-up air valve with an integrated idle air bypass and

Fig. 3 einen Schnitt des Warmlaufluftventils nach Fig. 2 entlang der Linie III - III.FIG. 3 shows a section of the warm-up air valve according to FIG. 2 along the line III - III.

Bei einer Brennkraftmaschine 1 ist am Zylinderkopf 1· eine aus einem Verteilergehäuse 2 und Ansaug-Schwingrohren 3 bestehende Saugleitungsanordnung 4 angeschlossen. Am Eintritt zum Verteilergehäuse 2 ist ein stutzenartiges Gehäuse 5 mit einer Drosselklappe 6 angeordnet, das an eine Luftansaugleitung 7 angeschlossen ist. Stromauf der Drosselklappe 6 zweigt von der Luftansaugleitung 7 eine Zuführleitung 8 ab, an die parallel zueinander ein Leerlaufluft-Bypass 9 und ein Warmlauf luftventil 10 angeschlossen sind. Der Auslaß 11 des Leerlaufluft-Bypasses 9 und der Auslaß 12 des Warmlaufluftventiles 10 sind an eine gemeinsame Austrittsleitung 13 angeschlossen, die in das Verteilergehäuse 2 mündet.In the case of an internal combustion engine 1, there is 1 on the cylinder head 1 A suction line arrangement 4 consisting of a distributor housing 2 and suction oscillating pipes 3 is connected. At the entrance to the distributor housing 2, a connector-like housing 5 with a throttle valve 6 is arranged, which is connected to an air intake line 7 is connected. Upstream of the throttle valve 6, a supply line 8 branches off from the air intake line 7, to which parallel to each other an idle air bypass 9 and a warm-up air valve 10 are connected.

Der Leerlaufluft-Bypass 9 umfaßt ein Steuergehäuse 14 mit einem Einlaß 15 und dem Auslaß 11 sowie einer Leerlaufluft-Stellschraube 16. Die Leerlaufluft-Stellschraube 16 dient zum Einstellen des Durchtrittsquerschnittes zwischen Einlaß 15 und Auslaß 11 im Steuergehäuse 14 und damit zum Einstellen der Leerlaufdrehzahl der betriebswarmen Maschine. Das Steuergehäuse 14 ist direkt an den Zylinderkopf 1' flächig angeschraubt. Dadurch wird das Steuergehäuse 14 bei betriebswarmem Zylinderkopf 1' durch unmittelbaren Wärmeübergang ständig beheizt, um eine Querschnittsverengung durch Vereisen zu vermeiden.The idle air bypass 9 comprises a control housing 14 with an inlet 15 and outlet 11 and an idle air adjusting screw 16. The idle air adjusting screw 16 is used to adjust the passage cross-section between inlet 15 and outlet 11 in the control housing 14 and thus to the Setting the idle speed of the machine at operating temperature. The control housing 14 is flat directly on the cylinder head 1 ' screwed on. As a result, when the cylinder head 1 'is at operating temperature, the control housing 14 becomes through direct heat transfer constantly heated in order to avoid a narrowing of the cross-section due to freezing.

Das Warmlaufluftventil 10 ist als Drehschieberventil aufgebaut, dessen nicht dargestelltes Betätigungselement elektrisch und durch die Wärme der Brennkraftmaschine beheizbar ist. Damit die Wärme der Brennkraftmaschine auf das Gehäuse 17 des Warmlaufluftventiles 10 übertragen werden kann, ist dieses über das Steuergehäuse 14 ebenfalls am Zylinderkopf 1' befestigt. Das Warmlaufluftventil 10 ist bei kalter Brennkraftmaschine geöffnet, so daß bei einem Kaltstart Zusatzluft zu einem im Verteilergehäuse 2 angeordneten Start-Einspritzventil 18 geleitet wird und während des Warmlaufes der Brennkraftmaschine der erhöhte Leistungsbedarf durch erhöhte Füllung befriedigt wird. Bei der vorliegenden Anordnung ergibt sich der weitere Vorteil, daß im Bereich des Start-Einspritzventiles 18 nicht nur die Warmlaufluft, sondern auch die Leerlaufluft zugeführt wird, was bei Warmund Heißstart eine bessere Verteilung des Startkraftstoffes ermöglicht. Weiterhin ist es auch möglich, den Leerlaufluft-Bypass 9 direkt in den Zylinderkopf 1· zu integrieren.The warm-up air valve 10 is constructed as a rotary slide valve, whose actuating element (not shown) can be heated electrically and by the heat of the internal combustion engine is. So that the heat from the internal combustion engine can be transferred to the housing 17 of the warm-up air valve 10 this is also attached to the cylinder head 1 'via the control housing 14. The warm-up air valve 10 is when the internal combustion engine is cold opened, so that additional air to a starting injection valve arranged in the distributor housing 2 during a cold start 18 is passed and the increased power requirement during the warm-up of the internal combustion engine increased filling is satisfied. In the present arrangement there is the further advantage that in the area of the Start injection valve 18 not only the warm-up air, but the idle air is also supplied, which is the case with warm and Hot start allows better distribution of the starting fuel. It is also possible to use the idle air bypass 9 to be integrated directly into the cylinder head 1.

Gemäß dem weiteren Ausführungsbeispiel nach den Fig. 2 und 3 sind der Leerlaufluft-Bypass 109 und das Warmlaufluftventil 110 in einem gemeinsamen Bypassluft-SteuergehäuseAccording to the further embodiment according to FIGS. 2 and 3 are the idle air bypass 109 and the warm-up air valve 110 in a common bypass air control housing

Dabei sind Verzweigungen in der Zuführleitung 108 zum Leerlaufluft-Bypass und zum Warmlaufluftventil bzw. eine Zusammenführung der Auslässe dieser beiden Bauteile zur gemeinsamen Austrittsleitung 113 in das Bypassluft-Steuergehäuse 117 integriert. Das Bypassluft-Steuergehäuse 117 ist mit einem Flansch 117' zur wärmeübertragenden Befestigung am Zylinderkopf versehen. Das Bypassluft-Steuergehäuse 117 umfaßt einen Einlaßkanal und einen Auslaßkanal 120, die sowohl über den Leerlaufluft-Bypass 109 als auch über das Warmlaufluftventil 110 miteinander in Verbindung stehen.summarized. There are branches in the supply line 108 to the idle air bypass and to the warm-up air valve or a merging of the outlets of these two components to the common outlet line 113 in the Integrated bypass air control housing 117. The bypass air control housing 117 is with a flange 117 'for heat transferring Attachment to the cylinder head. The bypass air control housing 117 includes an inlet duct and an exhaust duct 120, both via the idle air bypass 109 as well as via the warm-up air valve 110 are in communication with one another.

Das Bypassluft-Steuergehäuse 117 besteht aus einem Kopfteil 121 und einem Schaftteil 122. Der Kopfteil 121 wird im wesentlichen von einem schalenförmigen Deckel 123 gebildet. Im Kopfteil 121 ist ein Drehschieber 124 gelagert, der über ein im Schaftteil 122 angeordnetes, nicht dargestelltes Betätigungselement betätigbar ist. Der Raum 125 im Deckel 123 ist über eine Öffnung 126 mit dem Einlaßkanal 119 verbunden. Der Drehschieber 124 weist einen Durchlaß 127 auf, der je nach Stellung des Drehschiebers 124 mit einer zum Auslaßkanal 120 des Bypassluft-Steuergehäuses 117 führenden Durchlaßbohrung 128 mehr oder weniger zur Deckung gebracht wird.The bypass air control housing 117 consists of a head part 121 and a shaft part 122. The head part 121 is essentially formed by a bowl-shaped cover 123. A rotary slide valve 124 is mounted in the head part 121, which can be actuated via an actuating element (not shown) arranged in the shaft part 122. The room 125 in the cover 123 is connected to the inlet channel 119 via an opening 126. The rotary valve 124 has a Passage 127, which depending on the position of the rotary valve 124 with one to the outlet channel 120 of the bypass air control housing 117 leading through hole 128 is more or less brought to congruence.

Die Leerlaufluft-Stelischraube 116 ist in einer Gewindebohrung 129 im Schaftteil 122 angeordnet, die zwischen Einlaß- und Auslaßkanal 119 bzw. 120 des Bypass-Steuergehäuses 117 den Leerlaufluft-Bypass bildet.The idle air adjusting screw 116 is in a threaded bore 129 arranged in the shaft part 122 between the inlet and outlet channels 119 and 120 of the bypass control housing 117 forms the idle air bypass.

Durch Drehen der Leerlaufluft-Stellschraube 116 wird der Durchtrittsquerschnitt zwischen Einlaßkanal 119 und Auslaßkanal 120 verändert und dadurch die Leerlaufdrehzahl der betriebswarmen Maschine eingestellt.Turning the idle air adjustment screw 116 turns the Passage cross-section between inlet channel 119 and outlet channel 120 changed and thereby the idling speed the machine at operating temperature.
