Aus der DE-OS 25 27 774 ist bereits bekannt, ein Verteilergehäuse aus mehreren 'failstücken zusammenzusetzen, wodurch die Herstellung einiger Teile im Druckguiiverfuhren oder Kokillengußverfahren möglich wird, die fcei-re bogenförmigen Ansaugkanalabschnitte aufweisen.It is already known from DE-OS 25 27 774 to assemble a distributor housing from several pieces, which makes it possible to manufacture some parts using the pressure casting process or the chill casting process, which have four curved intake duct sections.

Hiervon ausgehend liegt der Neuerung die Aufgabe zugrunde, ein gattungsbildendes Luftansaugkanalsystem derart zu gestalten, daß alle Teile im Druckgußverfahren herstellbar sind.Based on this, the innovation is based on the task of designing a generic air intake duct system in such a way that all parts can be manufactured using the die-casting process.

Diese Aufgabe ist durch die im Kennzeichen des Schutzanspruchs 1 genannten Merkmale gelöst worden. Vorteilhafte Weiterbildungen sind mit den Merkmalen der Unteransprüche angegeben.This problem has been solved by the features mentioned in the characterizing part of claim 1. Advantageous further developments are specified with the features of the subclaims.

Mit der Neuerung ist ein kostengünstiges Luftansaugkanalsystem erreicht worden, das gegenüber be kannten Ausführungen funktionelle Vorteile hat, wie in der nachfolgenden Beschreibung eines in der Zeichnung dargestellten Aueführungsbeispiels noch näher erläutert wird.The innovation has resulted in a cost-effective air intake duct system that has functional advantages over known designs, as will be explained in more detail in the following description of an example shown in the drawing.

Views of the fitting piece from Fig. 1.
Fig. 1 shows a cross section of an air intake duct system 1 of an internal combustion engine, from which a cylinder head 2 of the internal combustion engine and a dividing plane 3 of sealing surfaces of two sections 4, 5 can be seen, which, when screwed together, form the air intake duct system 1. This system has a centrally arranged collective inlet duct 6, into which an air intake duct 7 opens, which is controlled by a throttle device 8. Spiral-shaped individual intake ducts 9 lead to the cylinders of the internal combustion engine, whereby each of these ducts 9 can be connected directly to the collective inlet duct 6 via a short-circuit duct 10 if an air flap 11 arranged in the short-circuit ducts 10 is brought into the open position. These air flaps 11 can be used to control the individual intake duct lengths (short or long) depending on the operating mode of the internal combustion engine.

Eine Kombination von metallischem Werkstoff für die Teilstücke und Kunststoff für die Paßstücke ist besonders vorteilhaft, da Fertigkeitsprobleme bei ausreichender Dimensionierung bei den äußeren Teilstücken nicht auftreten werden und durch Kunststoff eine Gewichtseinsparung erreicht wird. Die metallischen Teilstücke bewirken darüber hinaus eine Ansauggeräuschisolierung .A combination of metallic material for the sections and plastic for the fitting pieces is particularly advantageous, as problems with handling will not arise if the outer sections are sufficiently dimensioned and weight savings are achieved by using plastic. The metallic sections also provide intake noise insulation.
