Description
Die Erfindung betrifft ein Saugrohr für eine mehrzylindrige Brennkraftmaschine, gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a suction pipe for a multi-cylinder internal combustion engine, according to the generic term of claim 1.

Unter dem Begriff Schaltsaugrohre sind Saugrohre der gattungsgemäßen Art bekannt, bei denen durch entsprechende Konfiguration der Einzelrohre in Verbindung mit einem Sammelrohr durch Schaltmittel, wie z. B. Klappen, unterschiedliche Saugrohrlängen zur Wirkung gelangen. Im unteren Drehzahlbereich der Brennkraftmaschine werden längere wirksame Einzelrohre zur Schwingrohraufladung und im oberen Drehzahlbereich kürzere Saugrohrlängen ggf. größeren Querschnittes zur möglichst ungedrosselten Verbrennungsluft-Zufuhr geschaltet. Auch drei unterschiedliche Saugrohrlängen oder stufenlos variable Saugrohrlängen wurden schon vorgeschlagen. Alle diese Maßnahmen dienen der Füllungsgraderhöhung bzw. zur Leistungssteigerung der Brennkraftmaschine.Under the term variable intake manifolds are suction pipes of the generic type known in which by appropriate configuration of the individual tubes in conjunction with a manifold by switching means such. B. Flaps, different intake tube lengths come into effect. In the lower speed range of the engine are longer effective Single tubes for vibrating tube charging and in the upper speed range shorter intake manifold lengths possibly larger cross section as possible unthrottled combustion air supply switched. Also three different ones Suction tube lengths or infinitely variable intake manifold lengths have already been suggested. All these measures are used to increase the degree of for increasing the performance of the internal combustion engine.
Aufgabe der Erfindung ist es, ein Saugrohr der gattungsgemäßen Art vorzuschlagen, mit dem zusätzlich Verbrauchsvorteile insbesondere im Teillastbereich erzielbar sind.task The invention is a suction pipe of the generic type to suggest, with the addition Consumption advantages can be achieved in particular in the partial load range.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind den weiteren Patentansprüchen entnehmbar.These Task is according to the invention with the characterizing features of claim 1. advantageous Further developments of the invention can be taken from the further claims.
Erfindungsgemäß wurde erkannt, dass hinsichtlich des Brennstoff-Verbrauchs der Brennkraftmaschine in der Teillast ein Zusammenwirken sämtlicher Steuerungsparameter der Brennkraftmaschine zu sehen ist und das z. B. bei höheren Füllungen die Ladungswechselverluste ansteigen können. Ggf. kann ferner durch die Klopfregelung der Brennkraftmaschine eine Zündzeitpunktverschiebung nach spät gesteuert werden, die sowohl Verbrauchsnachteile als auch ggf. ein unerwünschtes Ansteigen der Abgastemperaturen bewirken kann. Andererseits soll in der Volllast bei niedriger Drehzahl eine wirkungsvolle Schwingrohraufladung mit der damit verbundenen Drehmomenterhöhung vorliegen. Exakt diesen Zusammenhängen trägt die Erfindung Rechnung, in dem sie in der Teillast zusätzlich eine „ultrakurze” Saugrohrlänge zuschaltet, die den Schwingrohraufladeeffekt definiert vermindert und die bei Volllast der Brennkraftmaschine weggeschaltet wird. In der Volllast sind dann die geometrisch vorgegebenen Saugrohrlängen wie an sich bekannt wirksam.According to the invention was recognized that in terms of fuel consumption of the internal combustion engine in the partial load is an interaction of all control parameters the internal combustion engine can be seen and the z. B. at higher fillings the charge exchange losses may increase. Possibly. can also by the knock control of the internal combustion engine retarded an ignition timing shift which are both consumption disadvantages and possibly an undesirable one Increase the exhaust gas temperatures can cause. On the other hand, in the full load at low speed an effective Schwingrohraufladung present with the associated increase in torque. Exactly these connections carries the invention Invoice, in which it additionally activates an "ultrashort" intake pipe length at partial load, which reduces the swing tube charging effect defined and that at Full load of the internal combustion engine is switched off. In the full load are then the geometrically predetermined intake pipe lengths as known per se effective.
Die Verbindung zwischen den Einzelrohren können bevorzugt in einem Zwischenflansch ausgebildet sein, der ggf. auch die Einspritzdüsen für die Brennstoffversorgung der Brennkraftmaschine und/oder Ladungssteuerungsklappen aufnimmt. Daraus resultiert eine fertigungstechnisch einfache Konstruktion, wobei die Verbindungen durch eingebohrte oder eingegossenen Kanäle gebildet sein können, die durch in Querbohrungen angeordnete Drehschieber verschließbar sind.The Connection between the individual tubes may preferably be in an intermediate flange be formed, if necessary, the injectors for the fuel supply the internal combustion engine and / or charge control flaps absorbs. This results in a production engineering simple construction, wherein the compounds formed by drilled or cast channels that can be can be closed by arranged in transverse bores rotary valve.
