Abstract

The energy recovery arrangement which utilises energy normally lost in internal combustion engines, has an exhaust gas driven turbine which actuates a heat pump for drawing heat from a refrigerating agent and from the exhaust gases. The thermal energy produced is sufficiently high for making conversion into mechanical energy profitable because of high temperature. The power generated can be used for generating electrical energy required in the internal combustion engine. This arrangement eliminates the use of other generator drives. The engine is also relieved from usual means for cooling because the heat pump acts as a cooling arrangement.

Description

Vorrichtung zur Nutzunff c er bei Ve rtrenn'inkraf tmas chinen verlorengehenden Energie.Device for the use of lost machines Energy.

Wegen der ständig steigenden Treibstoffkosten sollte es wünschens= wert sein, den Wirkungsgrad von Verbrennungskraftmaschinen durch Nutzung der üblicherweise durch Auspuffgase und Kühlung verloren= gehenden Energie (beim Ottomotor 65 % bis 70%,beim Dieselmotor ca 50%) zu erhöhen. Because of the ever increasing fuel costs, it should be desirable = be worth the efficiency of internal combustion engines by using the usually lost through exhaust gases and cooling = energy lost (for gasoline engines 65% to 70%, with diesel engines approx. 50%).

Diesen Zweck erfüllt folgende Vorrichtung:Eine von Auspuffgasen angetriebene Turbine betreibt eine Wärmepumpe,welche dem Kühlmedium und/oder den Abgasen Wärme entzieht und dafür Wärmeenergie liefert, die,im Gegensatz zu der im Kühlmedium und den Abgasen enthaltenen Wärmeenergie,eine Umwandlung in mechanische Energie lohneneswert macht,da die Temperatur hoch genug ist>um eine solche Umwandlung mit günstigen Wirkungsgrad durchzuführen.Diese mechanische Energie wird zweckmäßigerweise zur Stromerzeugung eingesetzt,wodurch der Verbrenn= ungsmotor vom Antrieb der Lichtmaschine,und damit der übrigen Zusatzaggregate des entsprechenden yahrzeuges,befreit wird.Gleich= falls befreit wird der Verbrennungsmotor vom Antrieb der üblichen Einrichtungen zur Motorkühlung (Kühlventilator, Wasserpumpe) ,da die Wärmepumpe die Kühlerfunktion übernimmt. The following device fulfills this purpose: One driven by exhaust gases Turbine operates a heat pump, which heats the cooling medium and / or the exhaust gases withdraws and supplies heat energy that, in contrast to that in the cooling medium and The thermal energy contained in the exhaust gases, a conversion into mechanical energy is worthwhile makes because the temperature is high enough> to make such a conversion with favorable This mechanical energy is expediently used for Electricity generation is used, which removes the internal combustion engine from driving the alternator, and so that the other additional units of the corresponding vehicle are released if released, the internal combustion engine is disconnected from the usual equipment for engine cooling (cooling fan, water pump), since the heat pump performs the cooling function takes over.

Besonders für Lastkraftwagen sollte die oben beschriebene Einricht= ung Vorteile bringen,da: a)Die meisten dieser Fahrzeuge eine große Pahrtstrecke im Jahr zu= rücklegen und ein möglichst wirtschaftlicher Betrieb deshalb wichtiger ist als ein niedriger Anschaffungspreis. For trucks in particular, the setup described above should = and bring advantages because: a) Most of these vehicles cover a long route put back a year and operating as economically as possible is therefore more important is than a lower purchase price.

b)Das Gewicht und Volumen einer solchen Einrichtung bei schweren Fahrzeugen nur eine relativ geringe Verschlechterung des Leistungs= gewichtes und des Nutzvolumens mit sich brächte. b) The weight and volume of such a device in the case of severe Vehicles only a relatively small deterioration in power = weight and of the usable volume would bring with it.

c)Gerade Lastkraftwagen durch zahlreiche energiebenötigende Zusatz= einrichtungen (Servoeinrichtungen,Kühlräume,etc) einen hohen Strom= bedarf haben, der nun nicht mehr auf Kosten der Motorkraft gedeckt werden müßte. c) Especially trucks due to numerous energy-consuming additions = facilities (servos, cold rooms, etc.) have a high electricity demand, which would no longer have to be covered at the expense of the engine power.
