Die Erfindung bezieht sich auf eine Brennkraftmaschine der im Oberbegriff des Hauptanspruches angegebenen Bauart.The invention relates to an internal combustion engine of the type specified in the preamble of the main claim.

Eine derartige Brennkraftmaschine ist in der Fachzeitschrift MTZ 38 (1977) 12, S. 59 1 und in der DB-"Einführungsschrift für den Kundendienst" -V81, S.20 gezeigt. Hierbei ist der Heizungs-Rücklaufkanal in einem Maschinengehäuse aus Leichtmetall einer Reihe von Zylindern benachbart nahe der Trennfläche zum Zylinderkopf verlaufend angeordnet.Such an internal combustion engine is in the journal MTZ 38 (1977) 12, p. 59 1 and in the DB "Introductory Guide for Customer Service" -V81, p.20. Here, the heating return duct runs in a machine housing made of light metal, adjacent to a row of cylinders, close to the separating surface from the cylinder head arranged.

Diese Anordnung des Heizungs-Rücklaufkanals ergibt bei einer Brennkraftmaschine mit einem Maschinengehäuse aus Eisenwerkstoff wegen der dabei langsameren Erwärmung des Maschinengehäuses in der Warmlaufperiode eine geringere Anwärmung des aus der Heizung rückfließenden Kühlmittels.This arrangement of the heating return duct results in an internal combustion engine with a machine housing Ferrous material because of the slower heating of the Machine housing during the warm-up period, the coolant flowing back from the heater warms up less.

Aufgabe der Erfindung ist es, bei einer Brennkraftmaschine der bekannten Bauart mit einem Maschinengehäuse aus Eisenwerkstoff eine Anordnung des Heizungs-Rücklaufkanals aufzuzeigen, durch die eine rasche Erwärmung des aus der Heizung rückfließenden Kühlmittels in der Warmlaufperiode der Brennkraftmaschine erreicht wird.The object of the invention is to provide an internal combustion engine of the known type with a machine housing made of ferrous material to show an arrangement of the heating return duct, through which a rapid heating of the from the heater Returning coolant is achieved in the warm-up period of the internal combustion engine.

Die Anordnung des Heizungs-Rüeklaufkarials in einem Leichtmetall-Zylinderkopf ergibt in Verbindung mit der guten Wärmeleitung dieses Materials eine rasche Erwärmung des rückfließenden Kühlmittels in der Warmlaufperiode der Brennkraftmaschine. Die Erwärmung erfolgt besonders rasch, wenn der übrige Kühlmantel des Zylinderkopfes kleinvolumig ist. Besonders vorteilhaft ist es, das Volumen des Heizungs-tfücklaufkanals als Teil eines insgesamt kleinvolumigen Kühlmantels des Zylinderkopfes vorzusehen. Insbesondere für diese Ausgestaltung ist der Heizungs-Räcklaufkanal nahe den Brennraumwänden einer mehrzylindrigen Reihen-Brennkraftmaschine verlaufend angeordnet, über das in den Kühlmantel des Maschinengehäuses eingebrachte, stark erwärmte Kühlmittel aus dem Heizungs-Rüeklaufkanal kann das Maschinengehäuse - unabhängig vom jeweiligen Werkstoff - in der Warmlaufperiode schneller erwärmt werden.The arrangement of the heating return karial in a light metal cylinder head in connection with the good heat conduction of this material results in a rapid heating of the returning coolant in the warm-up period of the Internal combustion engine. The heating takes place particularly quickly, if the rest of the cooling jacket of the cylinder head has a small volume. It is particularly advantageous to measure the volume of the heating tfücklaufkanal to be provided as part of an overall small-volume cooling jacket of the cylinder head. In particular for this embodiment, the heating return duct is close to the combustion chamber walls of a multi-cylinder in-line internal combustion engine arranged to run over the one introduced into the cooling jacket of the machine housing, strong Heated coolant from the heating return duct can be passed through the machine housing - regardless of the material - are heated up faster during the warm-up period.

. Weiter ist eine rasche und starke Erwärmung bei einer Brennkraftmaschine mit Mehrphasenkühlung erreicht, bei der in der Warmlaufperiode das Kühlmittel im Kühlmantel des Zylinderkopfes mindestens stark gedrosselt umläuft.. Next is a rapid and strong warming in one Internal combustion engine with multi-phase cooling achieved in which the coolant in the cooling jacket of the in the warm-up period The cylinder head rotates at least strongly throttled.

Schließlich kann bei einer Brennkraftmaschine mit einer Luftansauganlage mit einer vom Kühlmittel aus dem Heizungs-Rücklaufkanal beaufschlagten Vorwärmeinrichtung eine zügigere Saugrohrvorwärmung erreicht werden. Hierbei kann der Heizungs-Rüeklaufkanal im Abschnitt zwischen den Zu- und Ablaufkanälen der Vorwärmeinrichtung über die Temperatur des ablaufenden Kühlmittels aus der Vorwärmeinrichtung geregelt gesperrt werden.Finally, in an internal combustion engine with an air intake system with one of the coolant from the heating return duct activated preheater a faster intake manifold preheating can be achieved. Here can the heating return duct in the section between the inlet and outlet ducts of the preheater via the temperature of the coolant running off from the preheater can be blocked in a controlled manner.

Die Erfindung ist anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels beschrieben. .The invention is schematic based on one in the drawing illustrated embodiment described. .
