Abstract

The thermally-combined combustion engine has a body for burning in a circulating heat transfer medium with high boiling point, where an additional heat exchanger is provided. The body absorbs a portion of the thermal energy which is converted into mechanical or electrical energy.

Description

Beim TkV handelt es sich um einen Verbrennungsmotor, der dadurch gekennzeichnet ist, dass ein Teil der thermischen Energie in mechanische oder elektrische Energie umgewandelt wird. Ein Teil der thermischen Energie wird durch ein im Verbrennungskörper zirkulierendes Wärmeträgermedium mit einer hohen Siedetemperatur (z. B. Quecksilber) aufgenommen. Ein zusätzlicher Wärmetauscher im Abgasweg erhöht die Temperatur des Wärmeträgermediums zusätzlich.At the TkV is an internal combustion engine, which is characterized is that part of the thermal energy in mechanical or electrical Energy is converted. Part of the thermal energy becomes by a in the combustion body circulating heat transfer medium taken with a high boiling point (eg mercury). An additional one heat exchangers increased in the exhaust path the temperature of the heat transfer medium additionally.

Das so stark erhitzte Wärmeträgermedium wird nun durch einen zweiten Wärmetauscher geleitet, auf dessen Sekundärseite sich ein schnell siedendes Medium befindet (die Siedetemperatur des zweiten Mediums muss deutlich unter der Temperatur des erhitzten Wärmeträgermediums liegen). Das zweite Medium beginnt nun zu sieden. Der so entstehende Dampf wird durch eine Dampfturbine geleitet und treibt diese an. Die Dampfturbine erzeugt Strom, der von einem Elektromotor genutzt werden kann, um den Verbrennungsmotor zu unterstützen, wodurch der Wirkungsgrad eines TkVs deutlich höher ist als der eines gewöhnlichen Verbrennungsmotors.The so much heated heat transfer medium is now through a second heat exchanger headed, on its secondary side there is a fast-boiling medium (the boiling temperature the second medium must be well below the temperature of the heated medium Heat transfer medium lie). The second medium begins to boil. The resulting Steam is passed through a steam turbine and drives it. The steam turbine generates electricity that is used by an electric motor can be to support the internal combustion engine, reducing the efficiency a TkVs much higher is that of a common one Combustion engine.
