OIL SEPARATOR FOR SEPARATING OIL FROM AEROSOL IN A COMBUSTION ENGINE

The invention relates to an oil separator (4) for separating oil from aerosol in a combustion engine (1), comprising a housing (5) having an inlet opening (11) for the aerosol, an impeller (9) which can be rotatably driven about a rotational axis, and which is adapted for generating an aerosol flow along an axial direction of the impeller (9) and arranged in the housing (5), and an impact wall (15) which is designed in such a way that a projection of the impeller (9) oriented axially and downstream in the air flow impinges on the impact wall (15), wherein at least one part of a projection of the impeller (9) oriented axially and downstream in the air flow impinges on the inlet opening (11). The invention also relates to a combustion engine (1) comprising an oil separator (4) of this type and a motor vehicle having a combustion engine (1) of this type. 本发明涉及种用于在内燃机(1)中从气溶胶分离油的油分离器(4)，所述油分离器具有：壳体(5)，具有用于气溶胶的进入开口(11)；可围绕转动轴线旋转驱动的叶轮(9)，所述叶轮为了产生气溶胶流而沿着叶轮(9)的轴向方向适配并且设置在壳体(5)中；以及碰撞壁(15)，所述碰撞壁构成为使得所述叶轮(9)的轴向且朝气流下游地指向
