Abstract
Description
Die Erfindung bezieht sich auf ein Ansaugleitungsteil der im Oberbegriff des ersten Anspruchs angegebenen Art und geht aus von der gattungsbildenden DE-OS 15 76 355.The invention relates to a suction line part of the type specified in the preamble of the first claim and is based on the generic DE-OS 15 76 355.
Beschrieben ist darin eine Vorrichtung zum Entlüften des Gehäuses von Einspritz-Brennkraftmaschinen, bei der eine an das Maschinengehäuse angeschlossene Entlüftungsleitung an einer Stelle stromauf zur Drosselklappe mit dem Leitungssystem für die Ansaugluft in Verbindung steht. Um zu vermeiden, daß an der Drosselklappe bzw. an den benachbarten Wandungen bei tieferen Temperaturen Eisbildung, hervorgerufen durch Kondensate aus der Entlüftungsleitung, auftritt, weist der Klappenstutzen für die Drosselklappe bzw. ein benachbartes Leitungsteil einen Wärmetauscher für ein Heizmittel auf.Described therein is a device for venting the housing of injection internal combustion engines, in which a ventilation line connected to the machine housing is connected to the line system for the intake air at a point upstream of the throttle valve. In order to avoid the formation of ice on the throttle valve or on the adjacent walls at lower temperatures, caused by condensates from the ventilation line, the flap connection for the throttle valve or an adjacent line part has a heat exchanger for a heating medium.
Wenngleich mit Hilfe jener Vorrichtung die Vereisungsgefahr der Drosselklappe deutlich herabgesetzt werden kann, sind damit dennoch teilweise Eisbildungen im Drosselklappenbereich feststellbar. Jene Eisbildungen werden hervorgerufen durch sich nach Abstellen der Brennkraftmaschine ansammelndes Kondensat, welches schließlich - da bei stillstehender Brennkraftmaschine keine Heizwirkung erfolgt - gefriert.Although the risk of icing up of the throttle valve can be significantly reduced with the aid of that device, ice formation in the throttle valve area can still be determined in some cases. Those ice formations are caused by condensate accumulating after the internal combustion engine has been switched off, which finally freezes - since there is no heating effect when the internal combustion engine is at a standstill.
Aufgabe der Erfindung ist es daher, ein derartiges Ansaugleitungsteil so weiterzubilden, daß auch jene durch den letztgenannten Effekt bedingte Vereisungsgefahr der Drosselklappe verhindert wird.The object of the invention is therefore to develop such a suction line part in such a way that the risk of icing of the throttle valve caused by the latter effect is also prevented.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des ersten Anspruchs gelöst.This object is achieved by the characterizing features of the first claim.
Indem die Kurbelgehäuse-Entlüftungsleitung in eine geodätisch untenliegende wannenförmige Vertiefung des Ansaugleitungsteiles mündet, ist sichergestellt, daß sich das nach dem Abstellen der Brennkraftmaschine im Mündungsbereich ansammelnde Kondensat in jener wannenförmigen Vertiefung sammelt und allenfalls dort Eisbildung hervorruft. Ein Vereisen der Drosselklappe ist auf diese Weise sicher vermieden.
Erfolgt gemäß Anspruch 2 die Beheizung mittels eines erwärmten Fluids (beispielsweise dem Kühlmittel der Brennkraftmaschine), so ist es besonders vorteilhaft, die wannenförmige Vertiefung in einem Anbauelement vorzusehen, dessen Wandung von diesem Fluid durchströmt ist und welches lösbar mit dem Ansaugleitungsteil verbunden ist, da hiermit bei einer Demontage des Ansaugleitungsteiles der Fluidkreislauf nicht geöffnet werden muß, sondern einfach jenes Anbauelement vom Ansaugleitungsteil getrennt werden kann.By opening the crankcase ventilation line into a geodetically underlying trough-shaped recess of the intake line part, it is ensured that the condensate that accumulates in the mouth region after the internal combustion engine has been switched off collects in that trough-shaped recess and possibly causes ice formation there. This reliably prevents the throttle valve from icing up.
If heating is carried out according to
Im folgenden wird die vorliegende Erfindung anhand eines bevorzugten Ausführungsbeispieles näher beschrieben. Dargestellt ist ein Drosselklappenstutzen als Ansaugleitungsteil mit angeflanschtem Anbauelement im Schnitt.The present invention is described in more detail below on the basis of a preferred exemplary embodiment. A throttle body is shown as an intake line part with a flange-mounted attachment element in section.
Ein schematisch dargestellter Drosselklappenstutzen (Ansaugleitungsteil 1) ist im nicht gezeigten Ansaugtrakt einer Brennkraftmaschine angeordnet und mit einer um die Welle 2 schwenkbaren Drosselklappe 3 versehen. Stromauf jener Drosselklappe 3 mündet in einen Durch bruch 4 des Ansaugleitungsteiles 1 eine Kurbelgehäuse-Entlüftungsleitung 5, welche abzweigt von einer geeigneten Stelle des nicht dargestellten Kurbelgehäuses der Brennkraftmaschine. Die Kurbelgehäuse-Entlüftungsleitung 5 ist dabei auf einen Stutzen 6 eines Anbauelementes 7 aufgesteckt, welches eine wannenförmige Vertiefung 8 aufweist und mittels zweier Schraubverbindungen 9a, 9b am Ansaugleitungsteil 1 angeflanscht ist. In der Wandung des Anbauelementes 7 ist ein Ringkanal 10 vorgesehen, welcher über einen Zulaufstutzen 11 sowie einen Ablaufstutzen 12 mit dem Kühlmittelkreislauf der Brennkraftmaschine in Verbindung steht.A schematically illustrated throttle valve connector (intake duct part 1) is arranged in the intake tract of an internal combustion engine, not shown, and is provided with a
Kondensat, welches sich im Bereich des Durchbruchs 4 beim Zusammentreffen der durch das Ansaugleitungsteil 1 geführten Frischluft mit den durch die Kurbelgehäuse-Entlüftungsleitung 5 geführten Blow-by-Gasen bildet, sammelt sich teilweise in der wannenförmigen Vertiefung 8 an. Solange das Anbauelement 7 beheizt ist, ist ein Vereisen dieses Kondensates sicher ausgeschlossen. Bei stillstehender Brennkraftmaschine sowie sich abkühlendem Anbauelement 7 können zwar Kondensatreste innerhalb der wannenförmigen Vertiefung 8 vereisen, wirken sich dabei aber nicht störend aus. Ohne jene wannenförmige Vertiefung 8 hingegen würden sich Kondensatreste im Spaltbereich 13 zwischen der Drosselklappe 3 sowie der Innenwand des Ansaugleitungsteiles 1 ansammeln. Eine Vereisung an dieser Stelle wäre der Freigängigkeit bzw. Bewegbarkeit der Drosselklappe 3 hinderlich.
Um also ein mögliches Vereisen der Drosselklappe 3 auch bei stillstehender Brennkraftmaschine zu vermeiden, ist erfindungsgemäß am Ansaugleitungsteil 1 im Mündungsbereich der Entlüftungsleitung 5, also im Bereich des Durchbruches 4, die geodätisch unten liegende wannenförmige Vertiefung 8 vorgesehen.Condensate, which forms in the area of the
