Abstract
Description
Die Erfindung betrifft ein Entlüftungssystem für Blow-By-Gase aus einem Kurbelgehäuse einer Hubkolbenbrennkraftmaschine gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a ventilation system for blow-by gases from a crankcase a reciprocating internal combustion engine according to the preamble of the claim 1.
Bei Hubkolbenbrennkraftmaschinen gelangen aufgrund der hohen Drücke und der hin- und hergehenden Bewegung der Kolben Brenngase über die Kolbenringe in das Kurbelgehäuse. Diese Brenngase, auch „Blow-by" genannt, erhöhen den Druck im Kurbelgehäuse, schädigen das Schmieröl und erschweren die Abdichtung des Kurbelgehäuses. Das Kurbelgehäuse muss daher entlüftet werden. Dies geschieht in der Regel dadurch, dass man eine Verbindung in Form einer Entlüftungsleitung zwischen dem Kurbelgehäuse und dem Ansaugsystem der Hubkolbenbrennkraftmaschine schafft. Dadurch gelangen keine Schadstoffe in die Umwelt. Um das Schmieröl, das in fein verteilter Form in den Kurbelgehäusegasen enthalten ist, vom Ansaugsystem der Hubkolbenbrennkraftmaschine fernzuhalten, werden Ölabscheider vorzugsweise mit Filtern eingesetzt, über die die Kurbelgehäusegase geleitet werden, bevor sie in das Ansaugsystem der Hubkolbenbrennkraftmaschine gelangen. Setzt sich ein derartiger Filter zu, entsteht Überdruck im Kurbelgehäuse, der zu Ölauswurf über das Peilstabführungsrohr, zu Beschädigung von Dichtungen oder gar zu Motorschäden führen kann.at Reciprocating internal combustion engines arrive due to the high pressures and the reciprocating motion of the pistons of fuel gases through the piston rings in the crankcase. These fuel gases, also called "blow-by", increase the Pressure in the crankcase, damage the lubricating oil and complicate the sealing of the crankcase. The crankcase needs therefore vented become. This is usually done by having a connection in the form of a vent line between the crankcase and the intake system of the reciprocating internal combustion engine creates. Thereby no pollutants get into the environment. To the lubricating oil, which in finely divided form contained in the crankcase gases, from To keep intake of the reciprocating internal combustion engine, oil separator preferably used with filters over which the crankcase gases be passed before entering the intake of the reciprocating internal combustion engine reach. If such a filter sets, overpressure occurs in the crankcase, to oil spill over the Peilstabführungsrohr, to damage of seals or even cause engine damage.

Der Erfindung liegt die Aufgabe zugrunde, ein Entlüftungssystem derart zu verbessern, dass mit möglichst geringem Bauraumbedarf eine ausreichende Betriebssicherheit der Hubkolbenbrennkraftmaschine gewährleistet ist.Of the Invention has for its object to improve a ventilation system such that with as possible low space requirement sufficient reliability of the Hubkolbenbrennkraftmaschine ensured is.
Diese Aufgabe wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst.These Task is carried out according to the invention the features of claim 1 solved.
Ein wesentlicher Vorteil der Erfindung besteht darin, dass durch die Integration des Regelventils in den Filter ein kompaktes und bauraumneutrales Bauteil erschaffen wurde, welches die Betriebssicherheit des Entlüftungssystems bei Verstopfungen des Filters garantiert. Der Filter weist zwei Durchströmungswege für die Blow-by-Gase auf, die durch das Regelventil gesteuert werden. Der erste Weg führt über das Filterelement durch den Filter, so dass die Blow-by-Gase gefiltert dem Ansaugrohr zugeführt werden und der zweite Weg führt am Filterelement vorbei durch den Filter, wodurch die Blow-by-Gase ungefiltert das Ansaugsystem erreichen. Bei einem unzulässig hohen Verschmutzungsgrad des Filters und dadurch entstehendem Überdruck im Kurbelgehäuse öffnet das Regelventil und die Blow-by-Gase können am verstopften Filterelement vorbei abgesaugt werden. Die bei einem klassischen Bypass-Ventil benötigten Kanäle oder Leitungen können somit entfallen.One significant advantage of the invention is that through the Integration of the control valve in the filter a compact and space-neutral component was created, which the reliability of the ventilation system guaranteed at blockages of the filter. The filter has two By flow paths for the Blow-by gases, which are controlled by the control valve. Of the first way leads over that Filter element through the filter, so that the blow-by gases filtered be fed to the intake pipe and the second way leads passing the filter element through the filter, causing the blow-by gases unfiltered reach the intake system. For an impermissibly high degree of contamination the filter and thus resulting overpressure in the crankcase opens the Control valve and the blow-by gases may be on the clogged filter element be sucked over. The case of a classic bypass valve required channels or lines can thus omitted.
Vorteilhafterweise können auch hochabscheidende Filterelemente mit erhöhter Verschmutzungsgefahr zum Einsatz kommen, da ein eventuelles Versagen des Filters keine Folgeschäden für die Hubkolbenbrennkraftmaschine nach sich zieht.advantageously, can Also highly separating filter elements with increased risk of contamination to Use come because a possible failure of the filter no consequential damage to the reciprocating internal combustion engine pulls.
Vorteilhafterweise ist das Entlüftungssystem reparaturfreundlich ausgeführt, da das Bauteil (Filter mit integriertem Ventil) nachrüstbar ist.advantageously, the ventilation system is easy to repair executed because the component (filter with integrated valve) can be retrofitted.
Weitere Ausgestaltungen und Vorteile der Erfindung ergeben sich aus den übrigen Unteransprüchen und der Beschreibung.Further Embodiments and advantages of the invention will become apparent from the other dependent claims and the description.
