Saugrohranordnung für BrennkraftmaschinenIntake manifold for internal combustion engines

Die Erfindung betrifft eine Saugrohranordnung für Brennkraftmaschinen mit mindestens einer Zylinderreihe, wobei für mehrere Zylinder ein Sammelsaugrohr und zwischen diesem und den Zylindern je ein gekrümmtes, ein gesondertes Bauteil bildendes Einzelsaugrohr vorgesehen sind.The invention relates to an intake manifold for internal combustion engines with at least one row of cylinders, with a manifold suction pipe for several cylinders and between this and the cylinders each a curved individual suction tube forming a separate component are provided.

Derartige Saugrohranordnungen haben den Zweck, eine Schwingungsabstimmung der Ansaugluftströmung in den einzelnen Saugkanälen zu ermöglichen. Sie finden vor allem bei Viertakt-Einspritz-3rennkraftmaschinen nach dem Otto- und Dieselverfahren Anwendung. Schwierigkeiten bei dieser Saugrohranordnung treten wegen des hohen Raumbedarfs durch vielfach erforderliche große Saugrohrlängen und die Anordnung des Sammelsaugrohres am Ende der Einzelsaugrohre mit großem Abstand von den Zylindern auf. Außerdem ergeben die Verbindungsstellen der Einzelsaugrohre mit den Zylindern und dem Sammelsaugrohr einen hohen Bauaufwand sowie große Anforderungen an die i\aßgenauigkeit.Such intake pipe arrangements have the purpose of tuning the vibrations of the intake air flow in the individual intake ducts to enable. You will find them especially in four-stroke injection 3 racing engines according to the gasoline and diesel process. Difficulties with this intake manifold occur because of the high space requirement due to the large suction pipe lengths that are often required and the arrangement of the collecting suction pipe at the end the individual intake manifolds at a large distance from the cylinders. In addition, the connection points of the individual suction pipes also result the cylinders and the manifold suction pipe a high construction cost as well as great demands on the measurement accuracy.

Aufgrund dieser Schwierigkeiten sind Saugrohranordnungen bekannt, bei denen die Einzelsaugrohre und das Sammelsaugrohr einteilig miteinander verbunden sind. Dadurch ergibt sich ein schwierig herstellbares und teures Bauteil mit hohem Gewicht und starken Befestigungsteilen, weil dabei das Sammelsaugrohr durch die Einzelsaugrohre getragen wird.Because of these difficulties, suction pipe arrangements are known in which the individual suction pipes and the collecting suction pipe are made in one piece are connected to each other. This results in a difficult to manufacture and expensive component with high weight and strong Fastening parts because doing the manifold through the Single suction pipes is carried.

durch Veränderung der Längen ihrer parallelen Enden auf einfache weise auf das Schwingungsverhalten verschiedener Mamaschinen abstimmbar sind und der elastische Kunststoff zugleich geräuschmindernd wirkt.by changing the lengths of their parallel ends in a simple manner wise to the vibration behavior of different machines and the elastic plastic at the same time has a noise-reducing effect.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.

Sine Viertakt-Brennkraftmaschine 1 mit vier Zylindern 2 trägt an einer Längsseite je Zylinder einen Ansaugstutzen 3· Jeder Ansaugstutzen 3 trägt eine Einspritzdüse 4 und ist mit einem Steckanschluß 5 für ein Einzelsaugrohr 6 versehen. Über den Ansaugstutzen 3 ist ein Samme1saugrohr 7 auf der gleichen Längsseite der Maschine 1 befestigt. Dieses Sammelsaugrohr 7 v/eist gleichfalls Steckanschlüsse 8 für die Einzelsaugrohre auf, wobei die Steckanschlüsse 5 und 8 parallel zueinander angeordnet sind. Die Einzelsaugrohre 6 bestehen aus hart-elastischem Kunststoff, weiten eine G-esamtkrümmung von 1 öO auf und sind auf die Steckanschlüsse 5 an den Ansaugstutzen 3 und die Steckanschlüsse 8 am Sammelsaugrohr 7 aufgeschoben, wobei deren Elastizität gegebenenfalls auftretende Abstandstoleranzen ausgleicht. Die Steckanschlüsse 5 und 8 enthalten Dichtringe und sind mittels Schlauchbinder 9 gegen unbeabsichtigtes Lösen gesichert. Aufgrund ihres geringen Gewichts bedürfen die Einzelsaugrohre lediglich einer einfachen Befestigung an ihren Anschlüssen 5 und 8. Die auf das Schwingungsverhalten im Saugsystem der Maschine abgestimmte Länge der Sinzelsaugrohre 6 kai-n auf einfache V/eise durch Verändern ihrer parallel liegenden Enden 6' variiert v/erden. Das SainiLel saugrohr 7 ist eng an der Haschine 1 aniie. end angeordnet und damit ohne größeren Bauaufwand mitxels Befestigungselementen 7' schwingungssteif und raumsparend mit der Maschine 1 verbunden. Die Einzelsaugrohre 6 streben von den Anschlüssen 5 an der Maschine 1 ausgehend paarweise Z1Om Sammelsaugrohr 7 hin auseinander. Dadurch wird zwischen den Anschlüssen 8 am Sammelsaugrohr Raum für eine Eintrittsleitung 10 in das Sammelsaugrohr 7 geschaffen.A four-stroke internal combustion engine 1 with four cylinders 2 has an intake port 3 on one longitudinal side of each cylinder. A collecting suction pipe 7 is fastened on the same longitudinal side of the machine 1 via the suction connection 3. This collecting suction pipe 7 also has plug connections 8 for the individual suction pipes, the plug connections 5 and 8 being arranged parallel to one another. The individual suction pipes 6 are made of hard-elastic plastic, expand a total curvature of 1 öO and are pushed onto the plug connections 5 on the intake port 3 and the plug connections 8 on the collecting suction pipe 7, their elasticity compensating for any spacing tolerances that may occur. The plug connections 5 and 8 contain sealing rings and are secured against unintentional loosening by means of hose clips 9. Due to their low weight, the individual suction pipes only need a simple attachment to their connections 5 and 8. The length of the individual suction pipes 6, which is tailored to the vibration behavior in the suction system of the machine, varies in a simple way by changing their parallel ends 6 '. earth. The SainiLel suction pipe 7 is close to the machine 1 aniie. arranged at the end and thus connected to the machine 1 in a vibration-resistant and space-saving manner with xels fastening elements 7 'without major construction costs. Starting from the connections 5 on the machine 1, the individual suction pipes 6 strive apart in pairs Z 1 Om collecting suction pipe 7. As a result, space is created between the connections 8 on the collecting suction pipe for an inlet line 10 into the collecting suction pipe 7.

Die Einzelsciugrohre 6 sind quer zu ihrer 160 -Krümmung zusatzlich verwunden, wodurch der Raum für den Durchtritt aer Eintrittsleitung 10 zwischen den Einzelsaugrohren 8 weiter vergrößert wird. Die beiden äußeren Einzelsaugrohre 6 sind gegenüber den beiden inneren Einzelsaugrohren 6 mit entgegengesetzter Verwindung angeordnet, wodurch beiderseits der Einzelsaugrohre 6 zusätzlich Raum gewonnen wird. Alle Einzelsaugrohre sind jedoch gleich ausgebildet und lediglich mit unterschiedlich gerichteter Anordnung ihrer Verwindung an
den Anschlüssen 5 und 8 befestigtThe individual suction pipes 6 are additionally twisted transversely to their 160 curvature, as a result of which the space for the passage of the inlet line 10 between the individual suction pipes 8 is further enlarged. The two outer individual suction pipes 6 are arranged opposite the two inner individual suction pipes 6 with opposite twist, whereby additional space is gained on both sides of the individual suction pipes 6. However, all individual suction pipes are designed in the same way and only have their twisting arranged in different directions
the connections 5 and 8 attached
