Description
Stand der TechnikState of technology
Die Erfindung betrifft ein Verfahren zum Betreiben einer Brennkraftmaschine eines Kraftfahrzeugs zur Realisierung einer Standheizfunktion. Ferner betrifft die Erfindung eine Heizanlage für ein Kraftfahrzeug, das von einer Brennkraftmaschine angetrieben wird.The The invention relates to a method for operating an internal combustion engine a motor vehicle for the realization of a parking heater. Further the invention relates to a heating system for a motor vehicle, which of an internal combustion engine is driven.
Bei verbrauchsoptimierten Kolbenbrennkraftmaschinen, z.B. mit einer direkten Kraftstoffeinspritzung, Kraftstoffeinspritzung unter Hochdruck aus einem Speicher (Common-Rail) oder hochaufgeladenen Turbomotoren steht aufgrund des verbesserten Wirkungsgrades immer weniger Heizleistung zur Verfügung. Eine größere Heizleistung bei diesen Brennkraftmaschinen ist nicht nur im Hinblick auf den Komfort wünschenswert, die Kolbenbrennkraftmaschine und gegebenenfalls ein Abgaskatalysator sollen auch nach dem Start möglichst schnell auf eine optimale Betriebstemperatur gebracht werden, damit Schadstoffemissionen reduziert werden. Insbesondere bei Hybridantrieben, also Antrieben, die sowohl auf einer Kolbenbrennkraftmaschine als auch auf Elektromotoren beruhen und bei denen Betriebszustände existieren, in denen Brennkraftmaschine nur während eins Bruchteils der Betriebszeit als Antrieb dient, kann die Heizleistung sehr oft nicht erbracht werden. Bei derartigen Fahrzeugen sind daher separate Standheiz- oder Zusatz heizungen vorgesehen, welche einen entsprechenden Bauraum benötigen und aufgrund des erhöhten Montageaufwands zusätzliche Kosten verursachen.at consumption-optimized piston internal combustion engines, e.g. with a direct fuel injection, fuel injection under high pressure from a memory (common rail) or supercharged turbo engines is due to the improved efficiency less and less heating power available. A larger heating power in these internal combustion engines is not only in terms of Comfort desirable, the reciprocating internal combustion engine and optionally an exhaust gas catalyst should also after starting as possible quickly be brought to an optimal operating temperature, so pollutant emissions be reduced. Especially for hybrid drives, ie drives, both on a reciprocating internal combustion engine and on electric motors are based and where operating conditions exist in which internal combustion engine only during one fraction of the operating time serves as a drive, the heating power can very often can not be provided. In such vehicles are therefore separate Standheiz- or additional heaters provided, which a require appropriate space and due to the increased Additional installation work Cause costs.

Vorteile der ErfindungAdvantages of the invention
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren zum Betreiben einer Brennkraftmaschine eines Kraftfahrzeugs zur Realisierung einer Standheizfunktion dadurch gelöst, dass die Brennkraftmaschine in Abhängigkeit von Betriebsparametern und/oder Umgebungsparametern des Kraftfahrzeugs und/oder der Brennkraftmaschine oder in Abhängigkeit von einem Betätigungssignal selbsttätig gestartet, in einem vorgebbaren Betriebsmodus betrieben und wieder gestoppt wird, wenn eine vorgebbare Temperatur im Inneren des Fahrzeugs erreicht ist und/oder eine Kühlmitteltemperaturschwelle überschritten ist und/oder eine vorgebbare Zeit überschritten ist, oder der Fahrbetrieb des Fahrzeugs beginnt.These The object is achieved by a Method for operating an internal combustion engine of a motor vehicle to realize a parking heater function solved in that the internal combustion engine in dependence of operating parameters and / or environmental parameters of the motor vehicle and / or the internal combustion engine or in response to an actuation signal started automatically, operated in a predetermined operating mode and stopped again when a predeterminable temperature is reached inside the vehicle and / or exceeded a coolant temperature threshold is and / or a predetermined time is exceeded, or the Driving operation of the vehicle begins.
Die Erfindung wird ferner gelöst durch eine Heizanlage für ein Kraftfahrzeug, das von einer Brennkraftmaschine angetrieben wird, mit einem in einem Abgasstrang angeordneten, mit einem Kühlkreislauf der Brennkraftmaschine verbundenen Wärmetauscher und mit einer Steuereinrichtung, welche in Abhängigkeit von Betriebsparametern und/oder Umgebungsparametern des Kraftfahrzeugs und/oder der Brennkraftmaschine oder in Abhängigkeit von Betätigungssignalen die Brennkraftmaschine startet, in einem vorgebbaren Betriebsmodus betreibt und wieder stoppt, wenn eine vorgebbare, durch einen Temperatursensor im Innern des Fahrzeugs erfasste Temperatur erreicht ist, und/oder eine Kühlmitteltemperaturschwelle überschritten ist und/oder eine vorgebbare Zeit überschritten ist, oder der Fahrbetrieb des Fahrzeugs startet.The Invention is also solved by a heating system for a motor vehicle driven by an internal combustion engine is arranged with a arranged in an exhaust line, with a cooling circuit the internal combustion engine connected heat exchanger and with a control device, which depending of operating parameters and / or environmental parameters of the motor vehicle and / or the internal combustion engine or in response to actuation signals the internal combustion engine starts, in a predefinable operating mode operates and stops again when a specifiable, through a temperature sensor reached in the interior of the vehicle detected temperature, and / or exceeded a coolant temperature threshold is and / or a predetermined time is exceeded, or the Driving operation of the vehicle starts.
Grundidee der Erfindung ist es, die Brennkraftmaschine selbst zur Realisierung einer Standheizfunktion zu verwenden, also auf zusätzliche Aggregate völlig zu verzichten.The basic idea The invention is the internal combustion engine itself for the realization to use a parking heater, so on additional Aggregates completely to renounce.
Der vorgebbare Betriebsmodus, in dem die Brennkraftmaschine betrieben wird, ist bevorzugt der Leerlaufbetrieb der Brennkraftmaschine.Of the predeterminable operating mode in which the internal combustion engine is operated is, is preferably the idling operation of the internal combustion engine.
Bei einer sehr vorteilhaften Ausführungsform ist dabei vorgesehen, die Brennkraftmaschine im Leerlaufbetrieb mit einem nach spät verstellten Zündwinkel zu betrieben. Hierdurch wird eine Wirkungsgradverschlechterung erzielt, die eine höhere Abgastemperatur zur Folge hat, die wiederum für die Standheizfunktion besonders vorteilhaft ist.at a very advantageous embodiment it provided, the internal combustion engine in idle mode with one after the other adjusted firing angle to operate. As a result, an efficiency deterioration is achieved the one higher Exhaust gas temperature has the consequence, in turn, for the parking heater especially is advantageous.
Bei einer anderen vorteilhaften Ausführungsform ist vorgesehen, die Brennkraftmaschine im Leerlaufbetrieb mit erhöhter Leerlaufdrehzahl zu betreiben. In diesem Falle kann die Heizleistung sehr vorteilhaft über die Leerlaufdrehzahl eingestellt werden.at another advantageous embodiment is provided, the internal combustion engine in idle mode with increased idle speed to operate. In this case, the heating power can be very beneficial over the Idling speed can be set.
Eine sehr vorteilhafte Ausführungsform sieht vor, dass in dem vorgebbaren Betriebsmodus ein in einem Abgasstrang angeordneter, mit einem Kühlkreislauf der Brennkraftmaschine verbundener Wärmetauscher mit Abgas der Brennkraftmaschine beaufschlagt wird. Der Wärmetauscher ist hierzu bevorzugt in einem stromabwärts eines Katalysators verlaufenden und von einer ansteuerbaren Abgasklappe zu- und abschaltbaren Abgasbypass angeordnet. Auf diese Weise kann immer dann, wenn die Standheizfunktion gewünscht wird, die Abgasklappe so angesteuert werden, dass der Wärmetauscher vom Abgas durchströmt wird, sodass ein optimaler Wärmeaustausch zwischen Abgas und Kühlkreislauf der Brennkraftmaschine erfolgt.A very advantageous embodiment provides that in the predeterminable operating mode a in an exhaust line arranged, with a cooling circuit the internal combustion engine connected heat exchanger with exhaust gas of the internal combustion engine is charged. The heat exchanger this is preferably in a downstream of a catalyst extending and by a controllable exhaust flap on and off exhaust bypass arranged. In this way, whenever the parking heater function required is, the exhaust flap be controlled so that the heat exchanger flows through the exhaust gas so that optimum heat exchange between the exhaust gas and the cooling circuit the internal combustion engine takes place.

Es ist hervorzuheben, dass der Wärmetauscher über einen weiteren (nicht dargestellten) Kreislauf mit einer Absorptionskältemaschine verbunden sein kann, sodass neben einer Standheizfunktion auch eine Standkühlfunktion, d.h. Klimatisierungsfunktion, realisiert werden kann. Es ist des Weiteren zu bemerken, dass das vorstehend beschriebene Verfahren und die Heizanlage rein prinzipiell auch ohne Wärmetauscher realisierbar sind. In diesem Falle ist der Heizwirkungsgrad jedoch wesentlich schlechter.It It should be emphasized that the heat exchanger has a another (not shown) cycle with an absorption chiller can be connected, so that in addition to a parking heater and a Stand cooling function, i.e. Air conditioning function, can be realized. It is the Further note that the method described above and the heating system in principle can be realized without a heat exchanger. In this case, however, the heating efficiency is much worse.
