Title
(DE) BRENNKRAFTMASCHINE MIT EINEM KURBELGEHÄUSE FÜR MEHRERE ZYLINDER
(EN) INTERNAL COMBUSTION ENGINE HAVING A CRANKCASE FOR A PLURALITY OF CYLINDERS
(FR) MOTEUR À COMBUSTION INTERNE POURVU D'UN CARTER-MOTEUR POUR PLUSIEURS CYLINDRES
Abstract
(DE)
Die Erfindung betrifft eine Brennkraftmaschine mit einem Kurbelgehäuse (1) für mehrere Zylinder (2), welches im Bereich der Hauptlagerebenen hohle Hochversteifungen (3, 4, 4a, 4b) im Bereich der Seitenwände (1a, 1b) des Kurbelgehäuses (1) aufweist, wobei zumindest ein Teil der Hochversteifungen (3) als Ölrückrücklaufpassagen zwischen Zylinderkopf und Kurbelraum ausgebildet ist. Um besonders gute Ölabscheideraten zu ermöglichen, ist vorgesehen, dass zumindest eine Blow-By-Gas führende Hochversteifung (4a) einen Anschluss (5) für eine zu einem Ölabscheider (6) führende Blow-By-Gasleitung (7) aufweist.
(EN)
The invention relates to an internal combustion engine having a crankcase (1) for a plurality of cylinders (2), comprising in the region of the main bearing planes hollow structural reinforcements (3, 4, 4a, 4b) in the region of the side walls (1a, 1b) of the crank case (1), wherein at least part of the structural reinforcements (3) is designed as oil return passages between the cylinder head and crankcase. In order to allow for particularly good oil separation rates, at least one structural reinforcement (4a) carrying a blow-by gas has a connection (5) for a blow-by gas line (7) leading to an oil separator (6).
(FR)
L'invention concerne un moteur à combustion interne pourvu d'un carter-moteur (1) pour plusieurs cylindres (2), lequel carter-moteur présente des éléments de renforcement verticaux creux (3, 4, 4a, 4b) au niveau des plans de palier principal et au niveau des parois latérales (1a, 1b) du carter-moteur (1), au moins une partie des éléments de renforcement verticaux (3) étant réalisée sous forme de passages de retour d'huile entre la culasse et le carter de vilebrequin. L'objectif de l'invention est de permettre l'obtention de taux de séparation d'huile particulièrement bons. A cet effet, au moins un élément de renforcement vertical (4a), conduisant les gaz de carter, présente un raccord (5) destiné à une conduite de gaz de carter (7) menant au séparateur d'huile (6).
