Abstract

Die Erfindung betrifft ein Fahrzeug mit einer Brennkraftmaschine (20), die ein Kurbelgehäuse (14) und eine Aufladeeinrichtung (24) aufweist, mit einer Kurbelgehäuseentlüftungseinrichtung (10), die eine trägheitsbasierte Ölabscheideeinrichtung (11) mit mindestens einem trägheitsbasierten Ölabscheider (12), einen abgeschiedenes Öl zum Kurbelgehäuse (14) rückführenden Ölrücklauf (81) und eine Saugstrahlpumpe (16) aufweist, die mit komprimierter Luft (28) der Aufladeeinrichtung (24) angetrieben wird und die einen Unterdruck erzeugt, um Blow-By-Gas anzutreiben.The invention relates to a vehicle having an internal combustion engine (20), which has a crankcase (14) and a charging device (24), with a crankcase ventilation device (10) having an inertia - based oil separator (11) with at least one inertia - based oil separator (12) separated oil to the crankcase (14) recirculating oil return (81) and a suction jet pump (16) which is driven with compressed air (28) of the charging device (24) and which generates a negative pressure to drive blow-by gas.

Erfindungswesentlich ist, dass die Saugstrahlpumpe (16) von einer Steuereinrichtung (96) geregelt und/oder gesteuert wird.

Figure imgaf001
It is essential to the invention that the suction jet pump (16) is controlled and / or controlled by a control device (96).
