Description

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. 591 und in der DB-"Einfüh- rungsschrift für den Kundendienst" 9/81, 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 shown in the specialist journal MTZ 38 (1977) 12, p. 591 and in the DB "Introductory Document for Customer Service" 9/81, p.20. Here, the heating return duct is arranged in a machine housing made of light metal running adjacent to the separating surface to the cylinder head in a row of cylinders.

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 channel results in a lower heating of the coolant flowing back from the heating in an internal combustion engine with a machine housing made of ferrous material because of the slower heating of the machine housing in the warm-up period.

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 show an arrangement of the heating return channel in an internal combustion engine of the known type with a machine housing made of ferrous material, through which rapid heating of the coolant flowing back from the heating is achieved in the warm-up period of the internal combustion engine.

Diese Aufgabe ist mit dem kennzeichnenden Merkmal des Hauptanspruches gelöst.This object is achieved with the characterizing feature of the main claim.

Die Anordnung des Heizungs-Rücklaufkanals 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-Hücklaufkanals als Teil eines insgesamt kleinvolumigen Kühlmantels des Zylinderkopfes vorzusehen. Insbesondere für diese Ausgestaltung ist der Heizungs-RJcklaufkanal nahe den Brennraumwänden einer mehrzylindrigen Reihen-Brennkraftmaschine verlaufend angeordnet. über das in den Kühlmantel des Maschinengehäuses eingebrachte, stark erwärmte Kühlmittel aus dem Heizungs-Rücklaufkanal kann das Maschinengehäuse - unabhängig vom jeweiligen Werkstoff - in der Warmlaufperiode schneller erwärmt werden.The arrangement of the heating return duct in a light metal cylinder head, in conjunction 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 remaining cooling jacket of the cylinder head has a small volume. It is particularly advantageous to provide the volume of the heating return duct as part of an overall small-volume cooling jacket of the cylinder head. For this embodiment in particular, the heating return duct is arranged running near the combustion chamber walls of a multi-cylinder in-line internal combustion engine. The machine housing can be warmed up faster in the warm-up period - regardless of the material - via the strongly heated coolant from the heating return duct, which is introduced into the cooling jacket of the machine housing.

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.Furthermore, rapid and strong heating is achieved in an internal combustion engine with multi-phase cooling, in which the coolant circulates at least in a strongly throttled manner in the cooling jacket of the cylinder head during the warm-up period.

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-Rücklaufkanal im Abschnitt zwischen den Zu-und Ablaufkanälen der Vorwärmeinrichtung über die Temperatur des ablaufenden Kühlmittels aus der Vorwärmeinrichtung geregelt gesperrt werden.Finally, a faster intake manifold preheating can be achieved in an internal combustion engine with an air intake system with a preheating device acted upon by the coolant from the heating return duct. Here, the heating return duct in the section between the inlet and outlet ducts of the preheating device can be blocked in a controlled manner based on the temperature of the coolant flowing out of the preheating device.

Die Erfindung ist anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels beschrieben.The invention is described with reference to an embodiment shown schematically in the drawing.

Die Zeichnung zeigt in

  • Fig. 1 eine Brennkraftmaschine mit integriertem Heizungs-Rücklaufkanal für den Wärmetauscher einer Heizung für den Fahrgastraum,

Der Heizungs-Rücklaufkanal 5 ist überwiegend als ein zur Zylinderkopf-Dichtung 8 offener Kanal ausgebildet. Mit seinem Volumen kann der Heizungs-Rücklaufkanal 5 Teil eines insgesamt kleinvolumigen Kühlmantels des Zylinderkopfes 7 sein. Der Heizungs-Rücklaufkanal 5 erstreckt sich im wesentlichen über die Länge der Brennkraftmaschine 1 und ist nahe den die Brennräume 9 im Zylinderkopf 7 begrenzenden Wänden 10 verlaufend angeordnet. Über eine Verbindungsleitung 11 mündet der Heizungs-Rücklaufkanal 5 in eine Mischkammer 12 einer nicht gezeigten Temperatur-Regelvorrichtung. Die Mischkammer 12 steht über eine Leitung 13 mit einer Kühlmittel-Pumpe 14 in Verbindung.The internal combustion engine 1 comprises a machine housing 6 made of iron material and a cylinder head 7 made of light metal. The heating return duct 5 is arranged in the cylinder head 7. The heating return duct 5 is predominantly designed as a duct open to the cylinder head gasket 8. With its volume, the heating return duct 5 can be part of an overall small-volume cooling jacket of the cylinder head 7. The heating return duct 5 extends essentially over the length of the internal combustion engine 1 and is arranged running near the walls 10 delimiting the combustion chambers 9 in the cylinder head 7. Via a connecting line 11, the heating return duct 5 opens into a mixing chamber 12 of a temperature control device, not shown. The mixing chamber 12 is connected to a coolant pump 14 via a line 13.

Die Brennkraftmaschine 1 umfaßt weiter eine Luftansauganlage 15 mit einer vom Kühlmittel beaufschlagten Vorwärmeinrichtung 16. Im Zylinderkopf 7 sind mit dem Heizungs-Rücklaufkanal 5 verbundene Stichkanäle 17, 18 angeordnet, die im Bereich eines Anschlußflansches 19 der Luftansauganlage 15 mit in diese integrierte Zu- und Ablaufkanäle 20, 21 der Vorwärmeinrichtung 16 verbunden sind. Im Abschnitt zwischen den Stichkanälen 17, 18 ist der Heizungs-Rücklaufkanal 5 bei 22 gesperrt. Dieser kann über die Temperatur des ablaufenden Kühlmittels im Ablaufkanal 21 auch geregelt gesperrt werden.The internal combustion engine 1 further comprises an air intake system 15 with a preheating device 16 acted upon by the coolant. In the cylinder head 7, branch channels 17, 18 connected to the heating return channel 5 are arranged, which in the area of a connecting flange 19 of the air intake System 15 are connected to the inlet and outlet channels 20, 21 of the preheating device 16 integrated in this. In the section between the branch channels 17, 18, the heating return channel 5 is blocked at 22. This can also be blocked in a controlled manner via the temperature of the coolant flowing off in the drain channel 21.
