Abstract

The object of the invention is to utilise the waste heat in internal combustion engines, specifically by storing heat. An economically appropriate application of the invention is only possible if energy costs are high and it is possible to store the heat in a fashion which is favourable in terms of weight and in terms of costs. If storage of the heat involves heavy weights and high costs and energy costs are reasonable, it is not possible to apply the invention economically. However, in any event it is possible to use the invention for purposes of heating the engine and the vehicle. Whether the waste heat of the cooling water or of the exhaust fumes is stored will depend in future on which type of storage it is technically possible to implement with the smallest outlay in terms of volume, weight and costs.

Description

5'ärmespeicher für Kraftfahrzeuge5 'heat storage for motor vehicles

Es ist bekannt, daß beim Betrieb von Verbrennungsmotoren nur etwa ein Drittel der eingesetzten Energie in mechanische Arbeit umgewandelt wird. Etwa ein Drittel geht als Abwärme durch das Kühlsystem, etwa ein weiteres Drittel der eingesetzten Energie geht durch die Abwärme des Auspuff systems verloren. Nach dem heutigen Stand der Technik wird lediglich in der kalten Jahreszeit ein Teil der Kühlwasserabwarme zum Heizen des Wageninneren genutzt. Außerdem wird die in den Abgasen enthaltene Energie bei Abgastur->boladern zur Leistungssteigerung benutzt, jedoch überwiegend nur im Rennsport.It is known that in the operation of internal combustion engines only about a third of the energy used is converted into mechanical work. Approximately a third goes through the cooling system as waste heat, about another third of the The energy used is lost through the waste heat from the exhaust system. After this the current state of the art is only part of the cold season Waste heat from the cooling water used to heat the interior of the car. In addition, the Energy contained in exhaust gases used in exhaust gas turbochargers to increase performance, but mostly only in racing.

Ziel der Erfindung ist eine Nutzung der Abwärme bei Verbrennungsmotoren durch Abwärmespeicherung. Die gespeicherte Warme findet für Heizzwecke Verwendung.The aim of the invention is to use the waste heat in internal combustion engines through waste heat storage. The stored heat is used for heating purposes.

Diese Aufgabe löst die Erfindung durch die kennzeichnenden Merkmale des Anspruchs 1 Die Vorteile der Erfindung liegen auf der Hand: Die gespeicherte {.Vsrme, die sonst als Abwärme verloren gehen würde, wird genutzt. Durch das Speicbergewicht wird sich zwar Xein geringer Treibstoffrnehrverbrauch ergeben. Diesem Mehrverbrauch steht jedoch eine Einsparung entgegen, die sich aus der durch die Erfindung erreichbaren kürzeren Warmlaufphase des Motors ergibt, besonders in der kalten Jahreszeit.The invention solves this problem by means of the characterizing features of claim 1 The advantages of the invention are obvious: The stored {.Vsrme that would otherwise be lost as waste heat is used. Due to the excess weight Although there will be a low additional fuel consumption. This additional consumption however, this is opposed to a saving that can be achieved by the invention shorter engine warm-up phase, especially in the cold season.

Diese Einsparung wird im Alltagsbetrieb bei vielen Warmlaufphasen (z.B. bei Vertretern, die von Haus zu Haus fahren oder bei Taxen) erheblich sein, vor allem in winter.These savings are made in everyday operation with many warm-up phases (e.g. for representatives who drive from door to door or for taxis) be significant, especially in winter.

Aunerdem entfällt das bei Taxen hrufige Laufenlassen des Motors im Stand zum Heizen des Wageninneren.In addition, there is no need to let the engine run in taxis Stand for heating the interior of the car.

Das in der Zeichnung dargestellte Ausführungsbeispiel der Erfindung stellt die einfachste der möglichen Auführungen der Erfindung dar.The embodiment of the invention shown in the drawing represents the simplest of the possible embodiments of the invention.

Wir der kalte Motor 1 bei kaltem Speicher 9 und bei geschlossenen Wasser - Absperrventilen 6 gestartet, so wird über die geöffneten Thermostate 4a und die gMasserschläuche 8 die vom Motor kommende warme Kühlflüssigkeit in den Speicher 9 eintreten und diesen heizen. Kaltes Wasser fließt aus dem Speicher 9 zum Motor 1 und kühlt diesen. Erst wenn Speicher 9 aufgeheizt ist, öffnet das serienmsßige Thermostat 4, und der Motor wird auch über das serienmäßige Kühlsystem gekühlt. (über Kühler 2r Wird der kalte Motor 1 bei warmem Speicher 9 gestartet, so fließt über die Schlauch 8 und bei geöffneten Wasserabsperrventilen 6 warmes Wasser durch den Motor und die Wagenheizung 3. Bei Temperaturgleichheit von Motor 1 und Speiher 9 sollten die Absperrventile 6 geschlossen werden.We have the cold engine 1 when the memory 9 is cold and when it is closed If the water shut-off valves 6 are started, the thermostats 4a and the gMasserschlauch 8 the warm coolant coming from the engine in the memory 9 enter and heat it. Cold water flows from the memory 9 to the engine 1 and cools it. Only when memory 9 is heated up does the standard one open Thermostat 4, and the engine is also cooled by the standard cooling system. (via cooler 2r If the cold engine 1 is started with the storage tank 9 warm, the flow Warm water through the hose 8 and with the water shut-off valves 6 open the engine and the car heater 3. If the temperature of engine 1 and storage tank is the same 9 the shut-off valves 6 should be closed.

Hat der Motor Betriebstemperatur erreicht, so öffnen die Thermostate 4a und heizen den Speicher 9. Erst wenn dieser aufgeheizt ist, öffnet Thermostat 4 und gibt den serienrnäßigen Kühler 2 zum WasserdllrchfluS frei.When the engine has reached operating temperature, the thermostats open 4a and heat the storage tank 9. Only when it is heated does the thermostat open 4 and releases the standard cooler 2 for water flow.
