Die Erfindung betrifft eine Einrichtung zur- Kühlung der Luftdüse von Gaserzeugungsanlagen für Kraftfahrzeuge, bei der das Kühlmittel durch Thermosyphonwirkung im Kreislauf durch den Kühlmantel der Luftdüse und einen Wärmeaustauscher geführt wird·The invention relates to a device for cooling the air nozzle of gas generation systems for motor vehicles, in which the coolant is circulated through the cooling jacket by thermosyphon effect the air nozzle and a heat exchanger
Die Erfindung besteht darin, dass der Wärmeaustauscher derart in den Kühlmittelkreislauf des Motors eingeschaltet ist, dass das Düsenkühlmittel mittelbar vom Motorkühlmittel gekühlt wird.The invention consists in that the heat exchanger is switched into the coolant circuit of the engine in such a way that the Nozzle coolant is cooled indirectly by the engine coolant.
Hierdurch soll erreicht werden, dass der Wärmeaustauscher klein gehalten werden kann.This is intended to ensure that the heat exchanger can be kept small.
Ferner kann die Erwärmung des Motorkühlmittels vom Gaserzeuger her zum Vorwärmen des Motors bei kaltem Wetter, also zur Erleichterung des Anlassens benützt werden. Uenn der^mit Hilfe eines Gebläses angefachte Gaserzeuger gibt in der JEmäzone einen Teil der Wärme an die Luftdüse, von ,wo sie mit Hi£fe des Düsenkühlmittels im Wärmeaustauscher an das iKühlmittel und von diesem an den Motor abgegeben wird.Furthermore, the heating of the engine coolant from the gas generator can be used to preheat the engine in cold weather, so for relief used for starting. Uenn the ^ with the help of a fan fanned gas generators are part of the JEmäzone Heat to the air nozzle, from where it is with the aid of the nozzle coolant in the heat exchanger to the coolant and from there to the engine is delivered.
