Abstract

Die Erfindung betrifft ein Verfahren zur Kühlung von elektromagnetischen Betätigungsvorrichtungen für Brennkraftmaschinen-Hubventile, wobei durch jede elektromagnetische Betätigungsvorrichtung (=Aktuator) ein Teil eines in der Brennkraftmaschine umgewälzten Fluidstromes, insbesondere Schmierölstromes, hindurch geleitet wird. Die Menge des durch den/die Aktuator(en) hindurch geleiteten Fluidstromes ist veränderbar und wird mittels einer geeigneten Ventileinrichtung derart eingestellt, daß letztlich die kritische Bauteiltemperatur der Aktuatoren nicht überschritten wird. Bevorzugt wird eine der aktuellen Bauteiltemperatur entsprechende elektrische Kenngröße eines Aktuators in einer den Aktuatoren zugeordneten elektronischen Steuereinheit anhand des durch die Magnetspulen des Aktuators fließenden elektrischen Stromes ermittelt und in einer elektronischen Steuereinheit mit der kritischen Bauteiltemperatur oder einer dieser entsprechenden kritischen elektrischen Kenngröße verglichen, woraufhin die letztgenannte Steuereinheit die Ventileinrichtung im Hinblick auf den erforderlichen Kühl-Fluidstrom ansteuert.The invention relates to a method for cooling electromagnetic Actuators for internal combustion engine lift valves, being by each electromagnetic actuator (= actuator) is part of an in the internal combustion engine circulated fluid flow, in particular lubricating oil flow, is passed through. The amount of the actuator (s) fluid flow passed through it is changeable and is by means of a suitable Valve device set such that ultimately the critical component temperature the actuators are not exceeded. One is preferred an electrical characteristic corresponding to the current component temperature Actuator in an electronic control unit assigned to the actuators based on the electrical flowing through the solenoid coils of the actuator Current determined and in an electronic control unit with the critical component temperature or one of these corresponding critical electrical parameter compared, whereupon the latter control unit the valve device with regard to the required cooling fluid flow controls.
