Abstract

For the utilization of waste heat from combustion engines in a steam power process the steam power process consists of a pump, one or more heat exchangers in which the working medium under pressure is preheated, evaporated and superheated, a steam power machine which expands the working medium to condensation level, and a condenser in which the working medium is condensed through heat dissipation. The circuit is closed. The steam power machine can be constructionally integrated in the combustion engine or designed as a separate machine.

Description

Schienen- und Straßenfahrzeuge sowie Schiffe und Flugzeuge werden häufig durch Verbrennungskraftmaschinen, z.B. Diesel- oder Ottomotoren angetrieben.Rail and road vehicles as well as ships and planes are often powered by internal combustion engines, e.g. Diesel or petrol engines driven.

Bei diesen Verbrennungskraftmaschinen fällt ein großer Teil der Brennstoffenergie als Wärme ab und wird teils über Kühler teils über die Abgase an die Umwelt abgeführt.With these internal combustion engines come in mind greater Part of the fuel energy as heat and is partly over cooler partly over the exhaust gases are discharged to the environment.

Oft sind in Fahrzeugen oder Schiffen nur geringe oder gar keine Wärmeverbraucher vorhanden, so daß eine Abwärmenutzung, wie sie bei stationären Kraft-Wärme-Kopplungsanlagen bekannt ist, nur eingeschränkt möglich ist.They are often in vehicles or ships little or no heat consumers present so that a Waste heat recovery, as in stationary combined heat and power plants is known, only to a limited extent possible is.

Auch bei stationären Motoren kann eine Abwärmenutzung in einem Dampfkraftprozess sinnvoll sein, da oft keine oder nur geringe Wärmeverbraucher vorhanden sind.Waste heat can also be used with stationary engines make sense in a steam power process, since often none or only low heat consumers available.

Claims (1)

Gegenstand des Patentanspruches ist daher die Nutzung der Abwärme von Verbrennungskraftmaschinen in einem Dampfkraftprozess. Die gewonnene mechanische Leistung entlastet die Verbrennungskraftmaschine und führt damit zu einer Wirkungsgraderhöhung des Gesamtantriebssystems. Dies führt zu einer Erhöhung der Reichweite, zu einer Verringerung der Betriebskosten sowie zu einer Verringerung der Umweltbelastung durch die Abgase. Der Dampfkraftprozess besteht aus einer Pumpe, einem oder mehreren Wärmetauschern, in denen das unter Druck stehende Arbeitsmedium vorgewärmt, verdampft und überhitzt wird, einer Dampfkraftmaschine, welche das Arbeitsmedium auf Kondensationsdruck entspannt sowie einem Kondensator, in dem das Arbeitsmedium unter Wärmeabfuhr kondensiert. Der Kreislauf ist geschlossen. Die Dampfkraftmaschine kann in die Verbrennungskraftmaschine konstruktiv integriert sein oder als eine separate Maschine ausgeführt werden. Die Verdampfung des bedruckten Fluides soll die Kühlung der Verbrennungskraftmaschine darstellen, prinzipiell sowohl mit als auch ohne Zwischenmedium. Hierdurch wird ein intensiver Wärmefluß bei nahezu konstanter Temperatur erreicht. Dies ist vorteilhaft für die Kühlanforderungen der Verbrennungskraftmaschine als auch für die thermodynamische Güte des Gesamtprozesses. Die Kühltemperatur kann durch Wahl des Arbeitsfluides sowie des Druckes geeignet bestimmt werden. Die Abgaswärme kann zur weiteren Überhitzung des Dampfes verwendet werden. Der Vorteil in der Verwendung eines Dampfmotors für diese Anwendung liegt in der einer Verbrennungskraftmaschine ähnlichen Drehzahl, so dass, im Gegensatz zur Nutzung einer Dampfturbine, eine Kopplung mit dem Antriebsstrang der Verbrennungskraftmaschine ohne Getriebe möglich ist. Beim Arbeitsmedium kann es sich um Wasser oder aber auch um andere Fluide handeln. Insbesondere umfasst dieser Patentanspruch auch die Verwendung niedrig siedender Fluide, da dies für die Nutzung der Zylinderkühlung der Verbrennungskraftmaschine zur Verdampfung des Arbeitsmediums besonders sinnvoll erscheint. Der Patentanspruch umfasst auch Anlagen, in denen die Dampfkraftmaschine nicht mit dem Antriebsstrang der Verbrennungskraftmaschine gekoppelt ist, sondern beispielsweise Nebenaggregate des Fahrzeuges bzw. Schiffes antreibt.The subject of the claim is therefore the use of waste heat of internal combustion engines in a steam power process. The won mechanical power relieves the internal combustion engine and leads with it to an increase in efficiency of the overall drive system. This leads to an increase in Range, a reduction in operating costs as well as a Reduction of the environmental impact of the exhaust gases. The steam power process consists of a pump, one or more heat exchangers, in which the below Pressurized working medium preheated, evaporated and overheated is a steam engine, which the working medium to condensation pressure relaxed as well as a condenser in which the working medium under heat dissipation condensed. The cycle is closed. The steam engine can be structurally integrated in the internal combustion engine or run as a separate machine. The evaporation of the printed fluid is intended to cool the internal combustion engine represent, in principle both with and without intermediate medium. This creates an intense heat flow at almost constant temperature reached. This is advantageous for the cooling requirements the internal combustion engine as well as for the thermodynamic quality of the overall process. The cooling temperature can be determined by the choice of the working fluid and the pressure become. The exhaust heat can cause further overheating of steam can be used. The advantage in use a steam engine for this Application is similar to that of an internal combustion engine Speed, so that, unlike using a steam turbine, a coupling with the drive train of the internal combustion engine possible without gear is. The working medium can be water or else trade other fluids. In particular, this claim includes also use low boiling fluids as this is for use the cylinder cooling the internal combustion engine for evaporation of the working medium seems particularly useful. The claim also includes Plants in which the steam engine is not connected to the drive train the internal combustion engine is coupled, but for example Auxiliary units of the vehicle or ship drives.
