Abstract
Description
Gegenstand der Anmeldung: H y b r i d - M o t o r.Subject of the application: H y b r i d - M o t o r.
Die Anmeldung befasst sich mit einem Verbrennungsmotor, insbesondere Fahrzeugmotor, bei dem die Abwärme in den Kühlmänteln der Zylinder, aus der Nachverbrennungsanlage für Schadstoffe im Abgas und der Abgase selbst zur Erzeugung von Dampf ausgenutzt wirden, der in einem mit dem Verbrennungsmotor direkt gekuppelten Dampfmotor die Leistung des Antriebes erhöht, wodurch Brennstoff gespart und die Schadstoffmenge verringertwird.The application deals with an internal combustion engine, in particular Vehicle engine in which the waste heat in the cooling jackets of the cylinders, from the afterburning system for pollutants in the exhaust gas and the exhaust gases themselves are used to generate steam in a steam engine directly coupled to the combustion engine The power of the drive increases, which saves fuel and reduces the amount of pollutants is decreased.
Bei großen station#ären Verbrennungsmo;toren und im Schiffsbetrieb ist es bekannt die Abwärme aus den Kühlmänteln und Abgasen zur DampSerzeugung, zur Heizung und die Abgase zum Antrieb yon Auflade-Turbinen -Gebläsen zu verwerten. Bei Fahrzeugmotoren ist zwar die Verwertung der Abwärme aus Kühler und Auspuff für Heizungszwecke bekannt, Jedoch nicht in der Kombination nach der Anmeldung für die Erhöhung der Motorleistung.For large stationary combustion engines and in ship operation it is known to use the waste heat from the cooling jackets and exhaust gases to generate steam To utilize the heating and the exhaust gases to drive the turbocharger fans. In the case of vehicle engines, the recovery of waste heat from the cooler and exhaust is for Heating purposes known, but not in the combination after registration for the Increase in engine power.
Zur Begrenzung der Schadstoffmengen im Abgas erscheinen zur Zeit die Nachverbrennung und die kathalytische Umwandlung am wirksamstext. Beide Verfahren erzeugen Jedoch unverwertbare Wärme, die nur den Brennstoffverbrauch erhöhen. Angesichts der verkppenden EnergiE und der æteigenden Preise hierfür, ist ihre bessere Ausnutzung dringendes Gebot.To limit the amount of pollutants in the exhaust gas, the Post-combustion and the catalytic conversion at the most effective text. Both procedures However, they generate unusable heat that only increases fuel consumption. Given the bargaining energy and the increasing prices for it, is their better utilization urgent command.
Bei einem angenommenen Wirkungsgrad eines mittleren Bahrzeugmotors von 24 % können Je nach Beanspruchung ca 66.- 70 % verwertbarer Abwärme anfallen. Um diese möglichst rationell auszunutzen, schlägt die Anmeldung vor als, Kühl-, bzwe Arbeitsflüssigkeit für den Dampfmotor eine solche mit niedriger Siedetemperatur und Verdampfungs-' wärme zu verwenden. Da letztere im Kondensator abgezogen werden muß und für die Kr8fterzeugungausfällt, soll ihr Anteil möglichst klein sein. Es käme z.B. auch Trifluortrichloräthan mit einer Siedetemperatur von + 47.5 0C und einer Verdampfungswärme von ca. 34 kcal/ /kg in Frage.Assuming the efficiency of a medium-sized vehicle engine of 24%, depending on the load, around 66 - 70% of usable waste heat can be generated. In order to use this as efficiently as possible, the registration suggests as, cooling, or the working fluid for the steam engine is one with a low boiling point and use heat of vaporization. Since the latter are drawn off in the condenser must and fails for power generation, their share should be as small as possible. It For example, there would also be trifluorotrichloroethane with a boiling point of + 47.5 0C and a heat of vaporization of approx. 34 kcal / / kg in question.
Mit solchen Medien käme der Dampfteil auf einen Wirkungsgrad von ca. 20 - 25 , so daß der Zugewinn an.teistung und somit die Brenn stoffersparnis ca. 40 % betragen würde.With such media, the steam section would have an efficiency of approx. 20 - 25, so that the gain in output and thus the fuel saving approx. 40% would be.
Gemäß der Abbildung wird die Luft für den Verbrennungsmotor über das Luftfilter 1, den Vergaser 2, die Drosselklappe 3 in den Zylinder 4 angesaugt und mit dem mitgeführten Brennstoff in bekannter Weise zur Erafterzeugung verbrannt. Die Leistung des Kolbens 5 wird über Pleuel 7, Kurbel 8 auf Kurbelwelle 9 übertragen. Das Abgas strömt über die Nachverbrennungsanlage 12 für die Schadstoffe in den Wärmeaustauscher bzw. Verdampfer 13 durch Auspuff 14 entweder ins Freie oder zur Weiterverwertung als Heizung.According to the figure, the air for the internal combustion engine is supplied via the Air filter 1, the carburetor 2, the throttle valve 3 sucked into the cylinder 4 and burned with the fuel carried in a known manner to generate energy. The power of the piston 5 is transmitted to the crankshaft 9 via the connecting rod 7 and the crank 8. The exhaust gas flows through the post-combustion system 12 for the pollutants into the heat exchanger or evaporator 13 through exhaust 14 either into the open air or for further use as a heater.
Die SUhl-, bzw. Arbeitsflüssigkeit strömt durch den Kühlmantel 6, über leitung 15 durch den Verdampfer 13 und von dort als gespannter Dampf über Leitung 16, Regelventil 26, Einlaßventil 17 in den Dampfmotorzylinder 18 mit Kolben 19, dessen Leistung über Pleuel 20, Kurbel 21 auf die gemeinsame Kurbelwelle 9 übertragen wird. Der entspannte Dampf verlässt über Auslaßventil 22 den Dampfzylinder und tritt in den Kondensator 23, wo ihm durch Abkühlung die Verdampfungswärme entzogen wird. Das Kondensat wird aus dem Kondensat-Behälter 28 von der Umwälzpumpe 24 wieder zum Kühlmantel 6 des Verbrennungsmotors gepumpt, von wo der Kreislauf nez beginnt.The fluid or working fluid flows through the cooling jacket 6, Via line 15 through the evaporator 13 and from there as pressurized steam via line 16, control valve 26, inlet valve 17 in the steam engine cylinder 18 with piston 19, Its power is transmitted to the common crankshaft 9 via connecting rod 20, crank 21 will. The expanded steam leaves the steam cylinder via outlet valve 22 and enters into the condenser 23, where the heat of evaporation is withdrawn from it by cooling. The condensate is returned to the condensate container 28 by the circulation pump 24 Pumped cooling jacket 6 of the internal combustion engine, from where the cycle nez begins.
Die Drosselklappe 3 und das Dampf-Regleventil 26 können mit dem gemeinsamen Gaspedal 31 bedient werden.The throttle valve 3 and the steam regulating valve 26 can with the common Accelerator pedal 31 can be operated.
Für den Fall einer Panne am Verbrennungsmotor, kann mittels einer Zusatzheizung 72 die Dampferzeugung so aufrecht erhalten werden, daß eine Reparaturwerkstätte erreicht werden kann. Auch könnte damit zusätzliche Motorleistung für besondere Bedarfsfälle geschaffen werden.In the event of a breakdown in the internal combustion engine, a Additional heater 72 the steam generation can be maintained so that a repair shop can be reached. It could also allow additional engine power for special Needs are created.
Der Dampfkreislauf stellt nach der Anmeldung ein geschlossenes und versiegeltes System dar. Unvermeidliche Leckverluste werden aus dem Vorrat des Kondensatbehälters 28 gedeckt. Um diese gering zu halten, ist nach der Anmeldung die Verwendung eines doppeltwirkenden Dampf zylinders möglich, wobei die lecksichere Abdichtung der Kolbenstange leichter möglich ist.The steam cycle is a closed and after registration sealed system. Unavoidable leakage losses are from the supply of the condensate container 28 covered. In order to keep this to a minimum, it is advisable to use a double-acting steam cylinder possible, whereby the leak-proof sealing of the piston rod is easier possible.
Zur besseren Angleichung der günstigsten Drehzahlbereiche zwischen Verbrennungsmotor und Dampfmotor wäre es auch möglich ein Ubersetzungsgetriebe dazwischen zu setzen.For better alignment of the most favorable speed ranges between Internal combustion engine and steam engine, it would also be possible to use a transmission gear in between to put.
Nach der Anmeldung ist es auch möglich den Kondensator als Heizangskörper für den Fahrgastraum zu verwenden Die Anordnung gilt sinngemäß auch für Rotations-, bzw. Drehkolben-Motoren.After registration, it is also possible to use the condenser as a heating element to be used for the passenger compartment The arrangement also applies accordingly to rotation, or rotary piston engines.
