Die Erfindung betrifft ein Einlasssystem für eine Brennkraftmaschine mit zumindest zwei in V-Form angeordneten Zylinderbänken, mit einem im V-Raum zwischen den Zylinderbänken anordbaren Plenum, mit einer Einlassrohranordnung mit zumindest einem mit dem Plenum einerseits und zumindest einem Einlasskanal andererseits strömungsverbindbaren Einlassrohr 5 pro Zylinder, wobei die Einlassrohranordnung zum Anschluss an einen Zylinderkopf einer Zylinderbank einen für mehrere Zylinder gemeinsamen Flansch aufweist, wobei pro Zylinderbank eine für mehrere Zylinder einstückig ausgeführte Einlassrohranordnung vorgesehen ist, wobei vorzugsweise die Einlassrohranordnungen verschiedener Zylinderbänke als Gleichteile ausgeführt sind. 10The invention relates to an intake system for an internal combustion engine having at least two arranged in V-shape cylinder banks, with a V-space between the cylinder banks plenum, with an inlet pipe arrangement with at least one plenum on the one hand and at least one inlet channel on the other hand flow-connected inlet pipe 5 per cylinder wherein the inlet tube assembly for connection to a cylinder head of a cylinder bank has a flange common to a plurality of cylinders, wherein per cylinder bank is provided for a plurality of cylinder integrally running inlet tube assembly, wherein preferably the inlet tube assemblies of different cylinder banks are designed as equal parts. 10
Die US 5,003,932 A beschreibt ein mehrteiliges Einlasssystem mit einem im V-Raum einer Brennkraftmaschine mit V-förmig angeordneten Zylinderbänken positionierten Einlasssammler, welcher über einzelne Verbindungsrohre mit einer Einlassrohranordnung verbunden ist, welche direkt an den Zylinderköpfen der Zylinderbänke anflanschbar ist. Derartige aus starren Teilen 15 bestehende Einlasssysteme haben den Nachteil, dass sie exakt für einen bestimmten Einlassflanschwinkel konzipiert sind und dass eine Vormontage von Bauelementen, wie Einspritzsammler oder Einspritzventil kaum möglich ist. Ein weiterer Nachteil ist, dass ein für beide Zylinderbänke einteilig ausgeführte Einlassrohranordnung einen erheblichen Gussaufwand erfordert. 20No. 5,003,932 A describes a multi-part intake system with an intake manifold positioned in the V-space of an internal combustion engine with V-shaped cylinder banks, which is connected via individual connecting pipes to an intake pipe arrangement which can be flanged directly onto the cylinder heads of the cylinder banks. Such inlet systems consisting of rigid parts 15 have the disadvantage that they are designed exactly for a specific inlet flange angle and that pre-assembly of components such as injection manifold or injection valve is hardly possible. A further disadvantage is that an inlet pipe arrangement designed in one piece for both cylinder banks requires considerable casting effort. 20
Die US 5,544.629 A offenbart ein Einlasssystem für eine Brennkraftmaschine mit V-förmig angeordneten Zylindern. Pro Zylinderbank ist eine für mehrere Zylinder einstückig ausgeführte Einlassrohranordnung vorgesehen. 25 Auch die EP 0 370 515 B1 zeigt ein ähnliches Einlasssystem für eine Brennkraftmaschine mit V-förmig angeordneten Zylinderbänken.US 5,544,629 A discloses an intake system for an internal combustion engine with V-shaped cylinders. Per cylinder bank is provided for a plurality of cylinder integrally running inlet pipe arrangement. Also EP 0 370 515 B1 shows a similar intake system for an internal combustion engine with V-shaped cylinder banks.
Aufgabe der Erfindung ist es, ein Einlasssystem zu entwickeln, mit welchem sich eine einfache Fertigung und Montage erzielen lässt. 30The object of the invention is to develop an inlet system with which a simple production and assembly can be achieved. 30
Erfindungsgemäß wird dies dadurch erreicht, dass die Einlassrohranordnung stromaufwärts des Flansches Versteifungswände zwischen den Einlassrohren aufweist.According to the invention, this is achieved in that the inlet tube arrangement has stiffening walls between the inlet tubes upstream of the flange.
Besonders vorteilhaft ist es, wenn zwischen Plenum und jedem Einlassrohr der Einlassrohran-35 Ordnung ein elastisches Verbindungsglied, vorzugsweise eine Elastomermuffe, angeordnet ist. Die Verbindung der Einlassrohranordnung mit dem Plenum über Elastomermuffen erlaubt eine komplette Vormontage von Injektoren und Einspritzsammelleiste auf der Einlassrohranordnung zu einer Vormontagebaugruppe, da die bei V-Brennkraftmaschinen anfallenden Toleranzen bei der Montage der Einlassrohranordnung zwischen den beiden Zylinderbänken durch die Elasto-40 mermuffen ausgeglichen werden können. Dadurch kann auch unabhängig vom Einlassflanschwinkel auf einen Zwischenflansch verzichtet werden und trotzdem eine exakte Positionierung auf jeder Zylinderbank sichergestellt werden. Die Einlassrohranordnung ist dank der elastischen Verbindungsglieder für eine Vielzahl von V-Brennkraftmaschinen und Einlassflanschwinkel anwendbar. 45It is particularly advantageous if an elastic connecting element, preferably an elastomeric sleeve, is arranged between the plenum and each inlet tube of the inlet tube. The connection of the inlet tube assembly to the plenum via elastomeric sleeves allows for complete pre-assembly of injectors and injection manifold on the inlet tube assembly to a preassembled assembly since the tolerances associated with V-engines may be compensated for assembly of the inlet tube assembly between the two cylinder banks through the elastomeric couplings , As a result, it is also possible to dispense with an intermediate flange irrespective of the inlet flange angle and nevertheless to ensure exact positioning on each cylinder bank. The inlet tube assembly is applicable for a variety of V-engines and intake flange angles thanks to the elastic links. 45
Ein weiterer Vorteil durch das elastische Verbindungsglied ist, dass eine Schwingungsentkoppelung zwischen Plenum und Einlassrohranordnung ermöglicht wird.Another advantage of the elastic link is that vibration isolation between plenum and inlet tube assembly is enabled.
Zur einfacheren Montage der Einlassrohranordnung kann vorgesehen sein, dass die Einlass-50 rohranordnung in zumindest einer Versteifungswand eine Montageöffnung angeordnet ist.For easier assembly of the inlet pipe arrangement, it can be provided that the inlet pipe arrangement is arranged in at least one stiffening wall, a mounting opening.
Eine besonders platzsparende Anordnung im V-Raum wird ermöglicht, wenn pro Einlassrohranordnung Stutzen und Flansch bezüglich einer Mittelhochebene an verschiedenen Seiten angeordnet sind, wobei vorzugsweise die Stutzen verschiedener Einlassrohranordnungen in 55 Längsrichtung versetzt zueinander angeordnet sind und die Einlassrohranordnungen zweierA particularly space-saving arrangement in the V-space is made possible if each inlet pipe arrangement nozzle and flange with respect to a central plateau are arranged on different sides, preferably the nozzles of different inlet pipe assemblies are arranged offset in the longitudinal direction and the inlet pipe arrangements of two
