Abstract

The automobile has the energy usage reduced by recuperation of kinetic and thermal energy, the latter effected by using a steam cylinder and/or a hot air turbine for converting the waste heat of the i.c. engine into electrical energy for driving an auxiliary electric drive motor. Pref. the recovered electrical energy is used to charge a battery, connected to a pair of electric motors and switched to provide 6, 12, 24 and 48 volts, corresponding to 4 velocity stages, allowing the vehicle to be driven solely by the electric motor in town traffic.

Description

Es wird in der heutigen Zeit über die Umweltverschmutzung Ozonloch, Treibhauseffekt, Waldsterben usw. geklagt, aber niemand ist bereit daran etwas zu ändern d. h. niemand will Opfer dafür bringen, weniger km, langsamer fahren oder gar auf's Auto verzichten. Weil das nun mal so nicht zu ändern ist, will ich es versuchen diese Abgasluftverschmutzung auf technischem Wege zu verändern.It is about pollution today Ozone hole, greenhouse effect, forest dieback, etc. sued, but nobody is ready to change something d. H. nobody wants to make sacrifices less km, slow down or even do without a car. Because that can't be changed, I want to try it to change this exhaust air pollution technically.

Was ich hier vorschlage ist ein sparsameres Auto mit geringerem Verbrauch und das bei gleichbleibender Kraft. Das zu erreichen durch bessere Ausnutzung der Wärmeenergie das heißt Steigerung des thermischen Wirkungsgrades hth und durch Ausnutzung der Bewegungsenergie des Fahrzeuges indem man regenerative Bremsung anwendet, diese zum Teil potentiell speichert um beim Wiederbeschleunigen zu verbrauchen.What I am proposing here is a more economical car with lower consumption and with the same power. To achieve this by better utilizing the thermal energy, that is to say increasing the thermal efficiency h th, and by utilizing the kinetic energy of the vehicle by using regenerative braking, some of which is potentially stored in order to be used up again when accelerating again.

Um die übertriebene PS die zum Beschleunigen und Überwinden des Luftwiderstandes, (bei hohen Geschwindigkeiten) notwendig sind in Grenzen zu halten schlage ich die Unterstützung des Ottomotores durch einen 6 kW oder zwei 3 kW 24 V Reihenschluß Gleichstrommotoren, die zugleich auch für das regenerative Bremsen zu benutzen sind, vor. Der Reihenschlußmotor mit seinem großen Anzugsdrehmoment eignet sich somit sehr gut beim Anfahren den Hauptmotor zu stützen und so die Beschleunigung günstig beeinflussen ohne den Wagen mit zu großem Verbrennungsmotor bestücken zu müssen. Die Speisung der elektrischen Hilfsmotoren kann durch die rekuperative Abwärmeverwertung, die regenerative Bremsung und die Pufferbatterie der Akkus erfolgen. To the exaggerated horsepower to accelerate and overcome of air resistance (at high speeds) are necessary I keep the support of the Otto engine by a 6 kW or two 3 kW 24 V series connection DC motors that are also for the regenerative Brakes are to be used. The series motor with its large tightening torque is therefore very suitable for Starting to support the main motor and so the acceleration influence cheaply without too big the car Need to equip the internal combustion engine. Feeding the electrical Auxiliary engines can by the recuperative Waste heat recovery, regenerative braking and Backup battery of the batteries.  

Der heutige Ottomotor hat im Schnitt einen wirtschaftlichen Wirkungsgrad von hw∼26% der Rest geht noch immer als Abwärme verloren. Um nun diese Verluste möglich zu verringern habe ich das heiße Kühlwasser nicht in den Kühler sondern in einen Abhitzkessel geleitet und dort durch die Abgase und die elektrisch rückgewonnene überschüssigen Bremsenergie verdampft und so eine Dampfmenge von 1,6 kg, 8 atü und 234°C pro PS erzielt. Diese Dampfmenge in einem Zylinder entspannt ergab einen Rückgewinn von 16 mkgr/s also zusätzliche ¹/₅ PS pro PS des Hauptmotores. Außer diesem Rückgewinn, durch den Dampfzylinder, steht noch eine beträchtliche Wärmemenge im Kondensator zur Verfügung welche ich in einer Heißluftturbine ausnützte und weitere 12 mkgr/s pro PS nützen und so den wirtschaftlichen Wirkungsgrad auf hw∼35% heben.Today's gasoline engine has an average economic efficiency of h w ∼26%, the rest is still lost as waste heat. In order to reduce these losses as possible, I did not channel the hot cooling water into the cooler but into a waste heat boiler and evaporate it there through the exhaust gases and the electrically recovered excess braking energy and thus a steam quantity of 1.6 kg, 8 atm and 234 ° C per PS achieved. This amount of steam relaxed in a cylinder resulted in a recovery of 16 mkgr / s, which means additional ½ PS per horsepower of the main engine. In addition to this recovery through the steam cylinder, there is still a considerable amount of heat available in the condenser, which I used in a hot-air turbine and use another 12 mkgr / s per horsepower, thus increasing the economic efficiency to h w ∼35%.

Der Abhitzkessel war zugleich auch Katalysator weil er die CO und C₁On, durch die zugeführte Knallgase, restlos verbrannte.The waste heat boiler was also a catalyst because it completely burned the CO and C₁O n by the detonated gases.

Die elektrische und wärmetechnische Bestückung erhöht das Gewicht eines Mittelklassewagens um: 2×12 kg Gewicht der E-Motoren, 1 Turbogenerator von 15 kg, 4 Akkus je 13 kg, 1 Abhitzkessel von 16 kg, 1 Wasserdampfkondensator von 19 kg auf insgesamt 130 kg was jedoch durch den kleineren Hauptmotor und das Fehlen der Lichtmaschine, Anlasser und Schalldämpfer kompensiert wird.The electrical and thermal equipment increases the weight a mid-size car by: 2 × 12 kg weight of the electric motors, 1 turbogenerator of 15 kg, 4 batteries of 13 kg each, 1 waste heat boiler of 16 kg, 1 steam condenser from 19 kg to a total of 130 kg due to the smaller one Main engine and the absence of the alternator, starter and muffler is compensated.

Durch entsprechende Schaltungsweise in Neben- und Reihenschluß der Akkus und der 2 E-Motoren können 4 Stufen von 6-12-24-48 Volt Spannungskombinationen und damit 4 Geschwindigkeitsstufen erreicht werden und so dem Hauptmotor immer mit günstigsten Drehmomentfolgen oder im Stadtverkehr ohne Hauptmotor fahren zu können.By appropriate switching in shunt and series connection the batteries and the 2 electric motors can 4 levels from 6-12-24-48 volts Voltage combinations and thus 4 speed levels reached and so the main engine always with the most favorable torque sequences or to be able to drive in city traffic without a main engine.

Auch mit dem Turboaggregat allein ist schon eine Steigerung des hw auf über 30% zu erreichen, aber darüber später. Das wäre nun mein Vorschlag.Even with the turbo unit alone, the h w can be increased to over 30%, but more later. That would be my suggestion.

Da mein Vorschlag auf Energierückgewinnung ausgerichtet ist und dieses an und für sich nichts neues ist, sondern nur die Anwendung derselben im Kraftfahrzeugbau innovativ eingeführt werden kann, will ich auch nur dafür Patentschutz beanspruchen. Das heißt, die Ausnutzung der Abfallwärme des Verbrennungsmotors durch den Dampfzylinder und/oder die Heißluftturbine.1. Since my proposal is aimed at energy recovery and this in and of itself is nothing new, just that Innovative application of the same introduced in motor vehicle construction I just want to claim patent protection for it. That is, the utilization of the waste heat from the internal combustion engine through the steam cylinder and / or the hot air turbine. 2. Die Bremswuchtverwertung.2. The brake balancing.
