Beschreibung [0001] Die Erfindung betrifft einen Einlassstrang für eine Brennkraftmaschine, insbesondere für ein Motorrad, mit zumindest einem Einlassrohr, welches über einen Drosselklappenstutzen mit zumindest einem in einem Zylinderkopf der Brennkraftmaschine angeordneten Einlasskanal strömungsverbunden ist, wobei sowohl der Einlasskanal, als auch der Drosselklappenstutzen in einander zugewandten ersten und zweiten Flanschbereichen des Einlasskanals bzw. des Drosselklappenstutzens jeweils einen kreisrunden Strömungsquerschnitt aufweisen, wobei im Drossel klappenstutzen eine kreisrunde Drosselklappe um eine Drehachse drehbar gelagert ist.The invention relates to an intake manifold for an internal combustion engine, in particular for a motorcycle, having at least one inlet pipe, which is flow-connected via a throttle body with at least one arranged in a cylinder head of the internal combustion engine intake passage, wherein both the intake passage, and the throttle body in each having a first and second flange portions of the inlet channel and the throttle body respectively have a circular flow cross-section, wherein in the throttle valve stub a circular throttle valve is rotatably mounted about an axis of rotation.
[0002] Einlasskanäle von Zylinderköpfen weisen im allgemeinen eine ovale Eintrittsöffnung im Bereich der Flanschfläche auf, weshalb zum Anschluss eines Drosselklappenstutzens mit kreisrundem Querschnitt ein Zwischenstück verwendet werden muss, um die Querschnittsänderung zwischen dem ovalen und dem kreisrunden Querschnitt umsetzen zu können. Nachteilig ist, dass durch Verwendung des Zwischenstückes der Abstand zwischen der Drehachse der Drosselklappe und der Eintrittsöffnung in den Zylinder relativ groß ausgebildet ist, was zu einem vergleichsweise großen Totvolumen im Einlasskanal führt. Dies wirkt sich unmittelbar nachteilig auf den Verbrauch und auf die Verbrennungsstabilität der Brennkraftmaschine aus.Inlet ducts of cylinder heads generally have an oval inlet opening in the region of the flange, which is why an intermediate piece must be used to connect a throttle body with a circular cross section in order to implement the change in cross section between the oval and the circular cross section can. A disadvantage is that by using the intermediate piece, the distance between the axis of rotation of the throttle valve and the inlet opening in the cylinder is formed relatively large, resulting in a relatively large dead volume in the inlet channel. This has an immediate detrimental effect on the consumption and on the combustion stability of the internal combustion engine.
[0003] Weiters ist es bekannt, Klappen zur Drallbeeinflussung im Einlasskanal einzuordnen, siehe beispielsweise EP 0 234 478 A2, EP 0 173 014 A2, JP 0 150 425 A. Zur Lagerung und zur Betätigung der Klappen muss der Zylinderkopf entsprechend konzipiert sein, was mit zusätzlichem Aufwand verbunden ist.Furthermore, it is known to classify valves for swirl influence in the inlet channel, see for example EP 0 234 478 A2, EP 0173 014 A2, JP 0 150 425 A. For storage and operation of the flaps, the cylinder head must be designed accordingly associated with additional effort.
[0004] Weiters ist es aus der DE 10 2008/013934 A1 bekannt, in einem kreisrunden Saugrohr eine ovale Drehklappe anzuordnen.Furthermore, it is known from DE 10 2008/013934 A1, to arrange an oval rotary valve in a circular suction tube.
[0005] Aus der DE 10 207/914 A1 ist es bekannt, eine rechteckige Drallklappe in einem ovalen Einlassquerschnitt nahe dem Ansaugkanal im Bereich des Einlassflansches anzuordnen.From DE 10 207/914 A1 it is known to arrange a rectangular swirl flap in an oval inlet cross-section near the intake passage in the region of the inlet flange.
[0006] Die DE 10 119 280 A1 offenbart einen in einen Luftsammler eingesetzten Einsatz zur Aufnahme einer Klappe.DE 10 119 280 A1 discloses an insert used in an air collector for receiving a flap.
[0007] Die US 2005/0 247 287 A1 offenbart eine Brennkraftmaschine mit einem an einem Zylinderkopf angeschlossenen Drosselklappenstutzen, in welchem zwei Drosselklappen in Kanälen mit kreisrundem Querschnitt drehbar gelagert sind. Eine ähnliche Anordnung ist aus der US 6,196,186 B1 geoffenbart.The US 2005/0 247 287 A1 discloses an internal combustion engine having a throttle body connected to a cylinder head, in which two throttle valves are rotatably mounted in channels with a circular cross-section. A similar arrangement is disclosed in US 6,196,186 B1.
[0008] Aufgabe der Erfindung ist es, den Verbrauch und die Verbrennungsstabilität bei einer Brennkraftmaschine zu verbessern.The object of the invention is to improve consumption and combustion stability in an internal combustion engine.
[0009] Erfindungsgemäß wird dies dadurch erreicht, dass die Drosselklappe in zumindest einer Öffnungsstellung teilweise in den Einlasskanal hineinragt, wobei vorzugsweise der zweite Flanschbereich des Einlassstutzens unmittelbar an den ersten Flanschbereich des Einlasskanales grenzt und der Drosselklappenstutzen direkt mit dem Zylinderkopf verbunden ist.According to the invention, this is achieved in that the throttle flap protrudes partially into the inlet channel in at least one open position, wherein preferably the second flange region of the inlet nozzle directly adjoins the first flange region of the inlet channel and the throttle body is connected directly to the cylinder head.
[0010] Dadurch, dass der Drosselklappenstutzen ohne Zwischenstück am Zylinderkopf angeflanscht ist, kann das Totvolumen zwischen der Drosselklappe und der Einlassöffnung in den Brennraum auf ein Minimum reduziert werden, wodurch der Restgasgehalt im Teillastbereich wesentlich verringert werden kann, was in weiterer Folge zu einer deutlichen Verbesserung des Kraftstoffverbrauches und der Verbrennungsstabilität führt.Characterized in that the throttle body is flanged without adapter on the cylinder head, the dead volume between the throttle and the inlet opening into the combustion chamber can be reduced to a minimum, whereby the residual gas content in the partial load range can be substantially reduced, which subsequently leads to a significant Improvement of fuel consumption and combustion stability leads.
[0011] Durch die kreisrunde Form der Strömungsquerschnitte in den Flanschbereichen des Einlasskanales und des Drosselklappenstutzens kann die Drosselklappe in zumindest einer Öffnungsstellung in den Einlasskanal hineinragen, ohne dass ihre Bewegung durch die Wände des Einlasskanales behindert werden würde. Der Abstand zwischen der Drehachse der Drosselklappe zum Flanschbereich des Zylinderkopfes kann dabei kleiner als der Radius des Strömungsquerschnittes des Drosselklappenstutzens im zweiten Flanschbereich sein.Due to the circular shape of the flow cross sections in the flange portions of the inlet channel and the throttle body, the throttle valve may protrude into the inlet channel in at least one open position without its movement being hindered by the walls of the inlet channel. The distance between the axis of rotation of the throttle flap to the flange portion of the cylinder head may be smaller than the radius of the flow cross-section of the throttle body in the second flange.
[0012] Die Erfindung lässt sich sowohl bei Ein- als auch bei Mehrzylinder -Brennkraftmaschinen 1 /4The invention can be both in single and multi-cylinder internal combustion engines 1 /. 4
