24. Oktober 1974 Luftansaugan*lag*e für BrennkraftmaschinenOctober 24, 1974 Air intake for internal combustion engines

Die Erfindung "betrifft eine Luftansauganlage für Brennkraftmaschinen mit einem Verteilergehäuse und Saugrohren zu den einzelnen Verbrennungsräumen, wobei das Verteilergehäuse aus zwei Teilen besteht und zumindest ein Teil im Druckgußverfahren herstellbar ist sowie beide Teile ebene Anschlußflächen zur festen Verbindung miteinander aufweisen.The invention "relates to an air intake system for internal combustion engines with a distributor housing and suction pipes to the individual combustion chambers, whereby the Distributor housing consists of two parts and at least one part can be produced by die casting and both parts flat connection surfaces for a firm connection have with each other.

Bei einer in der Patentanmeldung P 23 40 O35.J vorgeschlagenen Luftansauganlage dieser Bauart ist vorgesehen, daß außen an dem Verteilergehäuse Saugrohre befestigt sind, die das Verteilergehäuse mit den Einlaßkanälen des Zylinderkopfes verbinden. Die Länge der Saugrohre und damit deren Raumbedarf kann gemäß der Anordnung der DT-OS 1 933 271 so festgelegt werden, daß bei geringerem Raumbedarf der Luftansauganlage eine optimale Schwingungsabstimmung der Saugströme erzielt wird.In one proposed in the patent application P 23 40 O35.J Air intake system of this type is provided that suction pipes attached to the outside of the distributor housing that connect the distributor housing to the inlet ports of the cylinder head. The length of the suction pipes and thus their space requirements can be determined according to the arrangement of DT-OS 1 933 271 so that with less Space requirement of the air intake system an optimal vibration adjustment of the suction flows is achieved.

Die Aufgabe der Erfindung besteht darin, unter Beibehaltung der Möglichkeit zur Schwingungsabstimmung der Saugrohre den Raumbedarf der gesamten Luftansauganlage weiter zu verringern.The object of the invention is while maintaining the possibility of tuning the vibrations of the intake manifolds the space requirements of the entire air intake system further decrease.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß innerhalb des Verteilergehäuses gekrümmte Teilabschnitte der Saugrohre angeordnet sind, die an weitere, außerhalb des Verteilergehäuses angeordnete Teilabschnitte der Saugrohre anschließen.This object is achieved according to the invention in that curved sections within the distributor housing of the suction pipes are arranged, which are attached to further, arranged outside of the distributor housing subsections of the suction pipes.

Da jeweils ein gekrümmter Teilabschnitt der einzelnen Saugrohre innerhalb des Verteilergehäuses liegt, wird der Raumbedarf für die Saugrohranlage bei gleicher länge der Saugrohre erheblich kleiner. Die Luftansauganlage kann somit insgesamt kompakter ausgeführt werden.Since each is a curved section of each If the intake manifold is located within the distributor housing, the space required for the intake manifold will be the same length the suction pipes are considerably smaller. The air intake system can thus be made more compact overall.

In verteilhafter Ausgestaltung der Erfindung sind die gekrümmten Teilabschnitte der Saugrohre als gesonderte Teile, vorzugsweise als unter sich gleiche Kunststoffteile, ausgebildet und an dem mit den weiteren Teilabschnitten versehenen Teil des Verteilergehäuses befestigt. Diese Ausführungsform bietet die Möglichkeit, für in Größe und Leistung unterschiedliche Typen von Brennkraftmaschinen die gleiche Luftansauganlage zu verwenden, wobei zur differenzierten Schwingungsabstimmung lediglich gekrümmte Teilabschnitte unterschiedlicher gestreckter Länge eingesetzt sind. Diese Bauweise erbringt eine Senkung der Herstellkosten da hierbei alle Teile der Luftansauganlage im Druckgußverfahren herstellbar sind. Wenn die gekrümmten Teilabschnitte der Saugrohre aus Kunststoff gefertigt sind, ergeben sich Vorteile hinsichtlich Schwingungs- und Geräuschdämpfung der Saugströmung.In a distributable embodiment of the invention, the curved sections of the suction pipes are separate parts, preferably designed as identical plastic parts and provided on the one with the further subsections Part of the distributor housing attached. This embodiment offers the possibility for in size and performance different types of internal combustion engines use the same air intake system, with differentiated Vibration tuning only curved sections different extended lengths are used. This design results in a reduction in manufacturing costs because all parts of the air intake system can be manufactured using the die-casting process. When the curved sections the suction pipes are made of plastic, there are advantages in terms of vibration and noise damping the suction flow.

In einer anderen Ausführungsform des Erfindungsgeg.enstandes sind die gekrümmten Teilabschnitte der Saugrohre einstückig mit einem weiteren gegossenen Teil des Verteilergehäuses ausgebildet. Dieses Teil kann im ebenfalls rationellen Kokillengußverfahren hergestellt werden. 'In another embodiment of the subject matter of the invention the curved sections of the suction pipes are integral with another cast part of the distributor housing educated. This part can also be manufactured using the equally efficient permanent mold casting process. '

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Sie zeigt einen Querschnitt einer Luftansauganlage für Brennkraftmaschinen mit einem zweiteiligen Verteilergehäuse, in dem gesondert hergestellte, gekrümmte Teilabschnitte der Saugrohre angeordnet sind.An exemplary embodiment of the invention is shown in the drawing. It shows a cross section of an air intake system for internal combustion engines with a two-part distributor housing, in the separately manufactured, curved Subsections of the suction pipes are arranged.
