Abstract

See full text

To ventilate a heat management system of an internal combustion engine, in which coolants circulate in several coolant circuits, connected inlets of a rotary valve may be opened and closed in a predetermined sequence, in order to ventilate one or more of the coolant circuits in the direction of the compensation tank, by means of at least one ventilation circuit which is in fluid connection with a coolant compensation tank. The rotary valve may be controlled by means of a control unit, wherein a non-connected inlet of the rotary valve is in fluid connection with the coolant compensation tank.
