Der Erfindung liegt die Aufgabe zu Grunde, die zuvor beschriebenen Kurbelgehäuse, welche einen Triebwerksraum und mindestens eine Kammer als Ölbehälter innerhalb des Kurbelgehäuses aufweisen, hinsichtlich des unbeabsichtigten Ölauswurfs zu optimieren.Of the The invention is based on the object, the crankcase described above, which has an engine room and at least one chamber as an oil tank within the crankcase, in terms of to optimize unintended oil ejection.
Die Aufgabe wird durch die Merkmale von Anspruch eins gelöst. In den Unteransprüchen sind die Ausgestaltungen der Erfindung dargestellt.The The object is solved by the features of claim one. In the subclaims are the embodiments of the invention shown.
Hierzu ist im Kurbelgehäuse eine Kurbelgehäuseentlüftung vorgesehen, welche einen Entlüftungskanal zur Entlüftung des Ölbehälters, einen Ölrücklauf-Kanal zur Rückführung des abgeschiedenen Öls in den Triebwerksraum und einen Ölvorabscheider zur Öl-Luft-Trennung aufweist, wobei der Ölvorabscheider den Entlüftungskanal mit dem Ölrücklauf-Kanal verbindet. Der Ölvorabscheider besitzt eine Durchtrittsöffnung vom Entlüftungskanal zum Ölrücklauf-Kanal und einen Anschluss für einen Ölnebelabscheider. Über die Durchtrittsöffnung fließt das aus dem Öl-Luftgemisch abgetrennte Öl in den Ölrücklauf-Kanal und von dort in den Triebwerksraum zurück.For this is a crankcase breather in the crankcase provided, which a vent channel for venting of the oil tank, an oil return channel for recycling the separated oil in the engine room and an oil pre-separator for oil-air separation wherein the Ölvorabscheider the vent passage connects to the oil return channel. The oil pre-separator has a passage opening from the venting channel to the oil return channel and a connection for an oil mist separator. About the passage opening the oil separated from the oil-air mixture flows back into the oil return channel and from there into the engine room.
Bei einer Brennkraftmaschine in V-Anordnung ist dann sowohl auf der A-Seite als auch der B-Seite des Kurbelgehäuses eine Kurbelgehäuse-Entlüftung angeordnet. Zur Verringerung des Bauraumbedarfs der Anordnung können der Öl-Rücklaufkanal der A-Seite sowie der Ölrücklauf-Kanal der B-Seite zu einem Ölrücklauf-Kanal zusammengefasst sein. In diesem Fall verbindet der Ölvorabscheider den Entlüftungskanal der A-Seite sowie den Entlüftungskanal der B-Seite mit dem einen Ölrücklauf-Kanal.at an internal combustion engine in V arrangement is then both on the A-side and the B-side of the crankcase a crankcase ventilation arranged. To reduce the space requirement of the arrangement can the oil return channel on the A side and the oil return channel the B-side combined to form an oil return channel be. In this case, the oil pre-separator connects the Venting channel of the A-side and the venting channel the B side with the one oil return channel.
Zur Erzielung einer maximalen Schräglauffähigkeit bei minimalen Ölauswurf ist der Ölvorabscheider an der geodätisch höchsten Position des Kurbelgehäuses und/oder mittig in Längsrichtung des Kurbelgehäuses angeordnet. Mit anderen Worten: Die Position des Ölvorabscheiders ist so gewählt, dass bei maximalem Schräglauf der Ölpegel im Entlüftungskanal nicht bis zum Ölvorabscheider heranreicht.to Achieving a maximum skew ability with minimal oil ejection is the oil pre-separator at the geodetic highest position of the crankcase and / or centrally in the longitudinal direction of the crankcase arranged. In other words: the position of the oil pre-separator is chosen so that at maximum skew the oil level in the ventilation duct is not up to the oil preseparator zoom ranges.
Neben einer kompakten Bauweise kennzeichnet die Erfindung eine weitere Verringerung des unbeabsichtigten Ölauswurfs auf Grund der zweistufigen Separation mittels Ölvorabscheider und Ölnebelabscheider.Next a compact design, the invention features a further Reduction of unintended oil ejection due to the two-stage separation by means of oil pre-separator and oil mist separator.
