Abstract

The engine is cooled by trifluortrichlorethane which has a suitable boiling point. An auxiliary cooling fluid container is connected to the engine cooling system above the liquid level so that only vapour can flow into the container. The exhaust from the engine is taken in a heating coil through the the container and then through the engine cooling system so that the heat of the exhaust is used to evaporate the cooling fluid. The vapour is used to drive a steam turbine after which it is condensed and returned by a pump. The turbine is connected to the engine output shaft by a variable speed belt drive so that it can run at constant speed regardless of the changes in engine speed.

Description

Zusatzausrüstung für einen Verbrennungsmotor zur besseren Ausnützung des Kraftstoffs. Additional equipment for an internal combustion engine for better utilization of fuel.

Verwendlmg An allen Arten von Verbrennungsmotoren. Use on all types of internal combustion engines.

Vorteil Bessere Umwandlung der im Kraftstoff enthaltenen Energie in Bewegungsenergie. Advantage Better conversion of the energy contained in the fuel in kinetic energy.

Beschreibunp; Als Kühlmittel für einem Verbrennungsmotor benützt man eine Flüßigkeit,die in etwa folgende Werte hat: a)Siedepunkt bei 760 forr etwa 40-50' C b)Siedepunkt bei 4-8 at etwa IooCO c)Erstarrungspunkt bei etwa -3o 0 d)darf nicht brennbar sein e)darf mit Eisen nicht reagieren Diese in etwa Eigenschaften erfüllt 1,2,2-Trifluortrichloräthan ( F2 ).An den Verbrennungsmotor ist noch ein Behälter angeschiossen,der mit dem Kühlsystem des Motorblocks so verbunden ist,daß nur Dampf in den Behälter überströmen kann,d.h. die Verbindunejmuß über dem Kühlflüßigkeitsspiegel sein.Die Abgasleitung des Verbrennungsmotors führt in Schlangenform durch den Behälter, dann durch dasKühlsystem des Motorblocks ins Freie.So entsteht im Behälter Heißdampf,und im Kühlsystem des Motorblocks geben die Abgase an die Kühlflüßigkeit noch Wärme ab.Eine Dampfturbine,die an den Verbrennungsmotor gekuppelt ist,übernimmt die Entspannung des Dampfes.Ein genügend großer Kühler sorgt für die Kondensation des Dampfes.0ber eine Pumpe gelangt das Kondensat wieder zurück ins Kühlsystem des Motorblocks.Da eine Turbine ihre beste Leistung nur bei einer ftir sie optimalen Drehzahl abgibt,ist es notwendig, sie so an den Motor zu kuppeln,daß sie stets mit ihrer optimalen DrehT zahl läuft.Dies gelingt bei Motoren mit ungleicher Betriebsdrehzahl indem man die Turbine mittels eines Keilriemen-bzw. eines Kettenvariators an den Motor kuppelt.Die automatische Verstellung des Variatons übernimmt ein Fliehkraftregler oder irgend eine andere Regelautomatik. Description Used as a coolant for an internal combustion engine one has a liquid that has roughly the following values: a) Boiling point at 760 forr about 40-50 'C b) boiling point at 4-8 at around IooCO c) freezing point at around -3o 0 d) may be non-flammable e) must not react with iron These properties are approximately meets 1,2,2-trifluorotrichloroethane (F2). To the combustion engine is still a Tank connected, which is connected to the cooling system of the engine block in such a way that only steam can overflow into the container, i.e. the connection must be above the cooling liquid level The exhaust pipe of the internal combustion engine runs in a serpentine shape through the container, then through the cooling system of the engine block to the outside. This creates superheated steam in the container, and In the engine block's cooling system, the exhaust gases give off heat to the cooling liquid A steam turbine, which is coupled to the combustion engine, takes over the relaxation A sufficiently large cooler ensures the condensation of the steam above a pump returns the condensate to the engine block's cooling system a turbine only delivers its best performance at a speed that is optimal for it it is necessary to couple it to the engine so that it always rotates at its optimum This can be done with engines with unequal operating speeds by adjusting the Turbine by means of a V-belt or. a chain variator to the engine automatic adjustment of the Variatons takes over a centrifugal governor or some another automatic control.

Arbeitsweise Der im Kühlsystem des Motorblocks entstehende Dampf strömt in den Behälter, erhitzt sich an den Abgasleitungen zu Heißdsmpf,entspannt sich über die Dampfturbine,wo die Wärmeenergie in Bewegungsenergie umgewandelt wird,gelangt dann in den Kühler zur Kondensation,von wo dann eine Pumpe das Kondensat ins Kühlsystem des Motorblocks pumpt. Mode of operation The steam generated in the cooling system of the engine block flows into the container, heats up on the exhaust pipes to hot steam, relaxed via the steam turbine, where the thermal energy is converted into kinetic energy then into the cooler for condensation, from where a pump then transfers the condensate into the cooling system of the engine block pumps.
