Description

Anordnung zur Abführung der Verlustwärme eines VerbrennungsmotorsArrangement for dissipating the waste heat of an internal combustion engine

Die Erfindung betrifft eine Anordnung zur Abführung der Veriustwärme eines Verbrennungsmotors eines Kraftfahrzeuges, bei der ein flüssiges Kühlmittel einer Kühlvorrichtung und zumindest teilweise einer Hetzvorrichtung des Fahrgastraumes des Kraftfahrzeuges zuführbar ist, sowie mit einer Abgasbehandlungsanlage zur Abführung der Verbrennungsgase.The invention relates to an arrangement for dissipating the waste heat of an internal combustion engine of a motor vehicle, in which a liquid coolant can be fed to a cooling device and at least partially to a heating device of the passenger compartment of the motor vehicle, as well as with an exhaust gas treatment system for dissipating the combustion gases.

Wird ein Kraftfahrzeug nach längerer Betriebspause gestartet, so sind der Verbrennungsmotor und das Kühlmitte! kalt. Erst allmählich nimmt der Verbrennungsmotor seine Betriebstemperatur an. Dadurch kommt auch die Heizeinrichtung im Fahrgastraum verzögert zur Wirkung. Für den Verbrennungsmotor wäre eine möglichst rasche Erwärmung auf die Betriebstemperatur erwünscht, weil Verschleiß, Wirkungsgrad und Zusammensetzung der Abgase günstig beeinflußt werden. Hierzu ist es bereits bekannt, ein zu der Kühlvorrichtung gehörendes Gebläse erst dann in Gang zu setzen, wenn der Motorblock eine gewisse Temperatur erreicht hat.If a motor vehicle is started after a long break, the combustion engine and the coolant are cold. The combustion engine only gradually reaches its operating temperature. This also delays the heating system in the passenger compartment from taking effect. It would be desirable for the combustion engine to warm up to operating temperature as quickly as possible, because this has a positive effect on wear, efficiency and the composition of the exhaust gases. It is already known to only start a fan belonging to the cooling device when the engine block has reached a certain temperature.

Der Erfindung liegt die Aufgabe zugrunde, die Aufheizung des Motorblockes des Verbrennungsmotors nach dem Starten gegenüber dem bisherigen Verhalten erheblich zu beschleunigen.The invention is based on the object of significantly accelerating the heating of the engine block of the internal combustion engine after starting compared to the previous behavior.

Diese Aufgabe wird gemäß der Erfindung durch einen Wärmetauscher zur Erwärmung des Kühlmittels durch die Verbrennungsase und eine Steuereinrichtung zur wahiweisen Umleitung der Verbrennungsgase über den Wärmetauscher erreicht. Die durch die Abgase abgeführte Verlustwärme des Verbrennungsmotors istThis object is achieved according to the invention by a heat exchanger for heating the coolant through the combustion gases and a control device for selectively diverting the combustion gases via the heat exchanger. The heat loss from the combustion engine dissipated through the exhaust gases is

auasreichend, über das Kühlmittel nicht nur den Motorblock zu erwärmen, sondern auch die Heizvorrichtung im Fahrgastraum zu apei sen.sufficient to not only heat the engine block via the coolant, but also to power the heating device in the passenger compartment.

Die Erfindung kann vorteilhaft in der Weise verwirklicht werden, daß die Steuereinrichtung ein Umlenkorgan zur teilweisen oder vollständigen Umleitung der Abgase aus einer Abgasleitung in den Wärmetauscher aufweist und daß der Wärmetauscher ein Mantelrohr und ein in dem Mantelrohr angeordnetes Rohrsystem umfaßt.The invention can be advantageously implemented in such a way that the control device has a deflection element for partially or completely diverting the exhaust gases from an exhaust line into the heat exchanger and that the heat exchanger comprises a jacket pipe and a pipe system arranged in the jacket pipe.

Es empfiehlt sich, für eine selbsttätige Arbeitsweise des Umlenkorgans zu sorgen. Dies kann nach einer Weiterbildung der Erfindung durch einen thermostatisch gesteuerten Drehschieber geschehen, der unmittelbar am Auspuffkrümmer des Verbrennungsmotors angeordnet ist. Auf diese Weise wird die mit den Verbrennungsgasen abgeführte Wärmemenge so wirksam wie möglich zur raschen Erhöhung der Betriebstemperatur des Verbrennungsmotors wie auch zur Heizung des Fahrgastraumes e ingesetzt.It is advisable to ensure that the deflection device operates automatically. According to a further development of the invention, this can be done by means of a thermostatically controlled rotary valve that is located directly on the exhaust manifold of the internal combustion engine. In this way, the amount of heat dissipated with the combustion gases is used as effectively as possible to quickly increase the operating temperature of the internal combustion engine and to heat the passenger compartment.

Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Es zeigtThe invention is explained in more detail below with reference to the drawing. It shows

Der in der Figur 1 angedeutete Verbrennungsmotor 1 eines Kraftfahrzeuges steht mit einem Kühlsystem in Verbindung, das mit einem flüssigen Kühlmittel gefüllt ist. Eine Kühlmittelpumpe 2 fördert das Kühlmittel durch einen Kühler 3 bekannter Bauart. Ein Teil des KühImitte I stromes wird bei Bedarf durch eine im Fahrgastraum des Kraftfahrzeuges angeordnete Heizvorrichtung 4 geleitet. Ein weiterer Teil des KühI mitte Ikreislaufes erstreckt sich von dem Zylinderkopf 5 des Verbrennungsmotors 1 zu einem Wärmetauscher 6, der unmittelbar neben dem Motorblock 7 des Verbrennungsmotors 1 angeordnet ist.The internal combustion engine 1 of a motor vehicle indicated in Figure 1 is connected to a cooling system that is filled with a liquid coolant. A coolant pump 2 conveys the coolant through a cooler 3 of known design. If required, part of the coolant flow is passed through a heating device 4 arranged in the passenger compartment of the motor vehicle. Another part of the coolant circuit extends from the cylinder head 5 of the internal combustion engine 1 to a heat exchanger 6, which is arranged directly next to the engine block 7 of the internal combustion engine 1.

Wie näher die Figur 2 zeigt, ist der Wärmetauscher 6 parallel zu einem Abschnitt 8 der Abgasleitung 9 des Verbrennungsmotors 1 {Figur 1) angeordnet. Ein System paralleler Steuerklappen 10 ist so angeordnet, daß die Verbrennungsgase wahleise durch den Abschnitt 8 oder den Wärmetauscher 6 geleitet werden können. Der Wärmetauscher 6 enthält eine auf Kernrohren 11 sitzende Rohrschlange 12. Eine zu dem unteren Anschluß der Rohrschlange 12 führende Rohrleitung 13 durchsetzt einen Thermostat regier 14, der direkt auf die Steuerklappen 10 wirkt. Hierdurch ist eine Abhängigkeit in der Weise geschaffen, daß die Steuerklappen 10 bei kaltem Verbrennungsmotor 1 die Verbrennungsgase vollständig durch den Wärmetauscher 6 leiten, von wo sie wieder in den normalen Weg münden. Die Rohrschlange 12 ist in einem Mantelrohr 18 aufgenommen.As shown in more detail in Figure 2, the heat exchanger 6 is arranged parallel to a section 8 of the exhaust line 9 of the internal combustion engine 1 (Figure 1). A system of parallel control flaps 10 is arranged so that the combustion gases can be guided either through the section 8 or the heat exchanger 6. The heat exchanger 6 contains a pipe coil 12 sitting on core pipes 11. A pipe 13 leading to the lower connection of the pipe coil 12 passes through a thermostat regulator 14, which acts directly on the control flaps 10. This creates a dependency in such a way that when the internal combustion engine 1 is cold, the control flaps 10 guide the combustion gases completely through the heat exchanger 6, from where they flow back into the normal path. The pipe coil 12 is accommodated in a jacket pipe 18.

Vom oberen Anschluß der Rohrschlange 12 gelangt das erwärmte Kühlwasser zu dem Verbrennungsmotor 1 und zu der Heizvorrichtung 4 im Fahrgastraum. Unmittelbar nach dem Start des Verbrennungsmotors 1 wird auf diese Weise dem Kühlsystem zusätzliche Wärme zugeführt und die Temperatur des KühlmittelsFrom the upper connection of the pipe coil 12, the heated cooling water reaches the combustion engine 1 and the heating device 4 in the passenger compartment. Immediately after the combustion engine 1 is started, additional heat is supplied to the cooling system in this way and the temperature of the coolant

rasch erhöht. Der Thermostat reg I er 14 verstellt die Steuerklappen 10 selbsttätig in der Richtung eines in der Figur 2 gezeigten Pfeiles 15, sobald die Temperatur des Kühlmittels normale Betriebswerte erreicht. Der Wärmetauscher 6 ist dann unwi rksam.rapidly increased. The thermostat regulator 14 automatically adjusts the control flaps 10 in the direction of an arrow 15 shown in Figure 2 as soon as the temperature of the coolant reaches normal operating values. The heat exchanger 6 is then ineffective.

Während in dem vorstehend beschriebenen Ausführungsbeispiel als Steuereinrichtung ein Thermostat regier 14 in Verbindung mit Steuerklappen 10 vorgesehen ist, kann vorteilhaft stattdessen ein Drehschieber 16 benutzt werden. Dieser ist in der Figur 3 in einer Stellung für normalen Betrieb, d.h. ohne Wärmetauscher, und in der Figur 4 in einer Stellung für den Betrieb mit Wärmetauscher gezeigt. Der Drehschieber sitzt auf einer Welle 17, die mehrere günstige Möglichkeiten für eine Betätigung durch einen Thermostat regier bietet. Insbesondere können zur Verbindung Hebe I gestänge, Zahnradgetriebe oder ein Riementrieb benutzt werden.While in the embodiment described above, a thermostat regulator 14 in conjunction with control flaps 10 is provided as the control device, a rotary slide valve 16 can advantageously be used instead. This is shown in Figure 3 in a position for normal operation, i.e. without a heat exchanger, and in Figure 4 in a position for operation with a heat exchanger. The rotary slide valve sits on a shaft 17, which offers several convenient options for actuation by a thermostat regulator. In particular, lifting rods, gear transmissions or a belt drive can be used for the connection.

Als Thermostat reg I er können für die Zwecke der Erfindung die bekannten, einen Bimetall enthaltenden mechanischen Regler eingesetzt werden, deren Genauigkeit völlig ausreichend ist. Während Regler dieser Art eine schleichende Arbeitsweise zeigen, kann es erwünscht sein, daß die Steuereinrichtung die Steuerklappen oder den Drehschieber schnell bzw. sprungartig betätigt. Dies ist durch einen Betättgungsmagneten zu erreichen, der durch das elektronische Motormanagement zu steuern i st.For the purposes of the invention, the known mechanical regulators containing a bimetal can be used as thermostat regulators, the accuracy of which is completely sufficient. While regulators of this type have a creeping mode of operation, it may be desirable for the control device to actuate the control flaps or the rotary valve quickly or abruptly. This can be achieved by means of an actuating magnet that can be controlled by the electronic engine management system.
