Description
Die Erfindung betrifft eine Luftansauganlage gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to an air intake system according to the preamble of claim 1.
Aus der gattungsgemäßen EP – 03 82 596 B1 ist eine Luftansauganlage bekannt, bei der jedem Zylinder innerhalb eines Luftsammlergehäuses zwei Ansaugrohre unterschiedlicher Länge zugeordnet sind. Diese beiden werden in je einem Y-förmigen Stutzen verzweigt, dessen Abgang als Einzelrohr entlang einer seitlichen Längswand aus dem Luftsammlergehäuse heraus dem entsprechenden Zylinder zugeführt ist.Out of the generic EP - 03 82 596 B1 is known as an air intake system, where each cylinder inside an air collector housing two intake pipes of different lengths are assigned. These both are each in a Y-shaped neck Branched, its outlet as a single tube along a lateral longitudinal wall from the air collector housing out of the corresponding cylinder is supplied.
Stromauf der Y-Verzweigung ist das jeweils kürzere Ansaugrohr mittels einer Drehklappe zur Verbesserung des Drehmomentverlaufes schaltbar ausgeführt.Upstream the Y-branch is the shorter intake pipe by means of a Rotary flap designed to improve the torque curve switchable.
Eine solche Anordnung ist nicht anwendbar bei zweireihigen V-Brennkraftmaschinen, da hierfür der Abgangsstutzen jeweils erneut aufgetrennt werden müßte und eine ungleiche Länge von dort zu den Zylindern der beiden Reihen entstehen würde.A such arrangement is not applicable to double-row V-type internal combustion engines, because of this Each outlet nozzle should be separated again and an unequal length from there to the cylinders of the two rows would arise.
Weiterhin ist dieser Stand der Technik nicht bei Reihenbrennkraftmaschine mit beispielsweise zwei Einlaßventilen pro Zylinder anwendbar, deren Einlaßventilachsen nicht in einer gemeinsamen, parallel zur Längsrichtung der Brennkraftmaschine verlaufenden Ebene angeordnet sind. Eine solche bezüglich der Zylinderlängsachse verdrehte Ventilanordnung zur Erzielung eines Einlaßdralles ist z. B. aus der DE – 17 51 401 bekannt.Farther This prior art is not in a series internal combustion engine with, for example, two intake valves applicable per cylinder whose inlet valve axes are not in one common, parallel to the longitudinal direction the internal combustion engine extending plane are arranged. A such respects the cylinder longitudinal axis twisted valve assembly to achieve an inlet twist is z. B. from DE - 17th 51 401 known.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Luftansauganlage zu schaffen, welche bei Hubkolbenbrennkraftmaschinen mit nicht in einer gemeinsamen, parallel zur Längsrichtung der Brennkraftmaschine verlaufenden Ebene angeordneten Einlaßventilachsen ein über den gesamten Drehzahlbereich der Brennkraftmaschine möglichst hohes Drehmoment liefert.Of the Invention is based on the object, a generic air intake to create which in reciprocating internal combustion engines with not in a common, parallel to the longitudinal direction of the internal combustion engine extending level arranged intake valve axes on the entire speed range of the internal combustion engine as possible high torque delivers.
Die Lösung dieser Aufgabe gelingt mit den Merkmalen des Patentanspruches 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen bezeichnet.The solution This object is achieved with the features of claim 1. Advantageous embodiments of the invention are indicated in the dependent claims.
Wenn bei einer gattungsgemäßen Luftansauganlage, die mit den Ventileinrichtungen verschließbaren Abschnitte der Ansaugrohre entlang zweier zueinander beabstandeter und im wesentlichen parallel in Längsrichtung verlaufender Reihen angeordnet sind, so können hiermit unter Bildung identischer Ansaugleitungslängen Einlaßkanäle im Zylinderkopf mit Frischluft versorgt werden, welche von Einlaßventilen beherrscht sind, die nicht in einer parallel zur Längsrichtung der Brennkraftmaschine verlaufenden Ebene angeordnet sind. Diese Anordnung ist vorteilhaft bei Reihenbrennkraftmaschinen anwendbar, die beispielsweise zwei bezüglich der Zylinderlängsachsen verdreht angeordnete Einlaßkanäle aufweisen. Ebenso vorteilhaft ist diese Anordnung bei V-Brennkraftmaschinen mit z. B. engem V-Winkel anwendbar, wobei hier die Ansaugrohre der einen Reihe unter Bildung gleicher Ansaugleitungslängen der einen Zylinderreihe und die Ansaugrohre der anderen Reihe der weiteren Zylinderreihe zugeordnet sind.If in a generic air intake system, the closable with the valve means sections of the intake pipes along two spaced-apart and substantially parallel longitudinal extending rows are arranged, so hereby to form identical Ansaugleitungslängen Inlet channels in the cylinder head be supplied with fresh air, which are dominated by intake valves, not in a direction parallel to the longitudinal direction of the internal combustion engine Level are arranged. This arrangement is advantageously applicable to in-line internal combustion engines, for example, two regarding the cylinder longitudinal axes Having twisted inlet channels. Also advantageous is this arrangement in V-type internal combustion engines with z. B. narrow V-angle applicable, in which case the intake pipes of a Row forming the same suction line lengths of a row of cylinders and the intake pipes of the other row of the further cylinder bank assigned.
In jedem Falle sind die Abgänge der Stutzen entlang einer seitlichen Längswandung des Luftsammlergehäuses angeordnet. Die durch die verdrehte Einlaßkanalanordnung oder die zweireihige Zylinderanordnung bedingte unterschiedliche Leitungslänge von den Stutzen zu den Austrittsöffnungen der Einlaßkanäle wird durch die erfindungsgemäße zueinander beabstandete Staffelung der Ansaugrohre kompensiert, so daß die für einen günstigen Drehmomentverlauf erforderlichen gleichen Ansaugleitungslängen erzielt werden.In in any case, the departures arranged the nozzle along a lateral longitudinal wall of the air collector housing. The through the twisted inlet channel assembly or the double row cylinder arrangement required different ones cable length from the nozzles to the outlet openings the inlet channels is by the invention to each other spaced graduation of the intake pipes compensated, so that for a Great Torque curve achieved the same suction line lengths required become.
In vorteilhafter Ausgestaltung sind Einlaßöffnungen der kurzen, verschließbaren Ansaugrohre innerhalb der Reihen in parallel zueinander verlaufenden Ebenen angeordnet und Einlaßöffnungen der längeren Ansaugrohre sind in zwei weiteren Ebenen angeordnet. Zur Erzielung gleicher Ansaugleitungslängen bezüglich der längeren Ansaugrohre sind auch diese in einer Querrichtung der Brennkraftmaschine seitlich zueinander gestaffelt angeordnet.In Advantageous embodiment are inlet openings of the short, closable intake pipes within the rows in parallel planes arranged and inlet openings the longer one Intake pipes are arranged in two further levels. To achieve same suction line lengths in terms of the longer one Intake pipes are also these in a transverse direction of the internal combustion engine Staggered laterally to each other.
Die Anordnung ist insgesamt kompakt und benötigt daher nur einen geringen Bauraum und läßt sich aufgrund der Querstaffelung innerhalb der Längserstreckung einer Brennkraftmaschine anordnen.The arrangement is compact overall and therefore requires only a small space and can be due to the transverse separation within the Arrange longitudinal extension of an internal combustion engine.
Weitere Vorteile der Erfindung ergeben sich aus der nachfolgenden, beispielhaften Erläuterung der Erfindung. Hierbei kann der gezeigte Zylinderkopf einer Reihenbrennkraftmaschine zugeordnet oder aber der gemeinsame Zylinderkopf einer zweireihigen V-Brennkraftmaschine sein.Further Advantages of the invention will become apparent from the following, exemplary Explanation of Invention. Here, the cylinder head shown a series internal combustion engine assigned or the common cylinder head of a double row V internal combustion engine.
