Description
Brennkraftmaschine mit im Winkel zueinander stehenden Zylinderreihen Die Erfindung bezieht sich auf eine Brennkraftmaschine mit im Winkel zueinander stehenden Zylinderreihen, bei welcher die Saugrohre in ein zwischen den Zylinderreihen angeordnetes Mittelstück münden.Internal combustion engine with rows of cylinders at an angle to one another The invention relates to an internal combustion engine with at an angle to each other standing rows of cylinders, in which the intake manifolds in between the rows of cylinders arranged center piece open.
Bei den bekannten Ausführungen dieser Art wird das Mittelstück mit den Saugrohren für beide Zylinderreihen als ein einziges Bauteil ausgebildet. Wegen der Länge des Gußstückes kann das Innere der Saugrohre und des Ansaugmittelstückes von Gußansätzen nicht ,genügend gereinigt werden, wobei die verbleibenden Gußreste die Durchströmgeschwindigkeit des Gasgemisches vermindern und Kondensation an den Wänden begünstigen, wodurch die Motorleistung sinkt. Für die Bearbeitung der Anschlußflansche der Saugrohre sind große und komplizierte Vorrichtungen notwendig, die ein flüssiges. Arbeiten nicht zulassen. Es wurde auch bereits vorgeschlagen, die Ansaugleitungen durch Zusammenfügen eines in der Längsebene geteilten und mit enteprechenden Ausnehmungen versehenen Zylinderblockes zu bilden. Da die einzelnen Hälften nicht maßgleicJh sind, ist die Bearbeitung der Trennflächen erschwert. Es sind zwei verschiedene Gußformen notwendig, und die Trennfuge muß sorgfältig abgedichtet werden, damit keine Falschluft in -die Ansaugleitung eindringt.In the known designs of this type, the middle piece is with the intake manifolds for both rows of cylinders are designed as a single component. Because the length of the casting can be the interior of the suction pipes and the suction center piece of casting approaches cannot be cleaned sufficiently, whereby the remaining casting residues reduce the flow rate of the gas mixture and condensation on the Favor walls, which reduces engine performance. For processing the connecting flanges the suction pipes are large and complex devices necessary for a liquid. Do not allow work. It has also been suggested that the suction lines by joining a split in the longitudinal plane and with corresponding recesses provided cylinder block to form. Since the individual halves are not dimensionally processing of the interfaces is more difficult. They are two different Molds are necessary, and the parting line must be carefully sealed with it no false air enters the suction line.
Der Erfindung entsprechend werden diese Nachteile dadurch .behoben, daß das Mittelstück derart geteilt ist, daß sich mit den der jeweiligen Zylinderreihe zugeordneten Saugrohren zwei maßgleiche. Hälften ergeben. Dadurch werden die Gußformen einfacher. Die Säuberung,des Gußstückes von Gußresten ist wegen der kurzen Baulänge ebenfalls einfach und, kann, was besonders vorteilhaft ist, genau durchgeführt werden. Die zur Bearbeitung der Saugrohre erforderlichen Vorrichtungen sind handlich. Bei Schäden an den Saugrohren bzw. dem Mittelstück muß nur die betreffende Hälfte ausgetauscht werden. Der Ausschuß ist geringer, als wenn die Saugrohre mit dem Mittelstück ein Bauteil wären.According to the invention, these disadvantages are resolved. that the center piece is divided in such a way that it corresponds to that of the respective cylinder bank assigned Suction pipes two dimensionally. Halves yield. This makes the molds simpler. The cleaning of the casting from casting residues is also possible because of the short overall length easily and, which is particularly advantageous, can be carried out precisely. the Devices required for processing the suction pipes are handy. In case of damage on the suction pipes or the center piece only the relevant half has to be replaced will. The committee is less than if the suction pipes with the middle piece Component would be.
Der Vorteil einer Teilung des Mittelstückes tritt noch deutlicher hervor, wenn das Mittelstück eine an sich bekannte Vorwärmekammer bildet, wobei jede Hälfte der Vorwärmekammer mit einem zu ihrem Heizraum führenden Heizrohr versehen ist. Obwohl die Vorwärmekammer einen Vorwärmeraum und' zwei Saugkanäle aufweist, ist ihre Herstellung wegen der Teilung genau so leicht wie bei einem einfachen Mi,tbelstiick. Wegen. der Bearbeitung der Anliegeflächen der beiden Hälften des Ansaugmittelstückes. bzw. der Vorwärmekammer ist es vorteilhaft, wenn die Teilungsebene die Winkelhalbierende des von den Zylinderreihen eingeschlossenen Winkels darstellt. Zur Versteifung der zu .den einzelnen Zylindern führenden Saugrohre sind diese durch Stege miteinander verbunden. Die Befestigung der Saugrohre an. den Zylindern erfolgt durch Spannbügel, wobei die freien Enden der Saugrohre zur Auflage der Spannbügel mit Ansätzen versehen sind.The advantage of dividing the middle section becomes even clearer emerges when the middle piece forms a preheating chamber known per se, wherein each half of the preheating chamber is provided with a heating pipe leading to its boiler room is. Although the preheating chamber has a preheating space and two suction channels, it is just as easy to manufacture because of the division as it is for a simple mixture. Because. the processing of the contact surfaces of the two halves of the intake center piece. or the preheating chamber, it is advantageous if the dividing plane bisects the angle of the angle enclosed by the rows of cylinders. To stiffen the to .den the individual cylinders leading suction pipes, these are connected by webs tied together. The attachment of the suction pipes. the cylinders is carried out by means of clamps, wherein the free ends of the suction pipes are provided with lugs to support the clamps are.
