Abstract
Description
Es ist bekannt, daß durch verschiedenartige Methoden der Aufbereitung von flüssigen und gasförmigen Kraftstoffen deren Verhalten im Verbrennungsprozeß, dieser selbst, die Qualität des Abgases usw. beeinflußt werden kann.It is known that by various methods of processing of liquid and gaseous fuels their behavior in Combustion process, this itself, the quality of the exhaust gas, etc. can be influenced.
So ergeben sich z. B. bei der Verwendung von sog. Emulsionskraftstoffen,
das sind z. B. Öle, denen mit Hilfe eines Emulgators ein bestimmter Prozentsatz
von Wasser beigemischt wurde, u. a. folgende Vorteile:
Kraftstoffersparnis, Verlängerung der Lebensdauer des Motors und der
Filterstandzeiten, Verringerung der Rußanteile im Abgas, der Cancerogene
und Mutagene und der Stickstoffanteile sowie des Motorlärmes, usw.So there are z. B. when using so-called. Emulsion fuels, z. B. Oils to which a certain percentage of water has been added using an emulsifier include the following advantages:
Fuel savings, longer engine life and filter service life, less soot in the exhaust gas, carcinogens and mutagens and nitrogen and engine noise, etc.
Für Motoren in Fahrzeugen müssen die Emulsionskraftstoffe kältefest sein und dürfen auch im Sommer keine Entmischungstendenzen zeigen.For engines in vehicles, the emulsion fuels must be cold-resistant and must not show any tendency towards segregation even in summer.
Als Nachteil steht den genannten Vorteilen der relativ hohe Preis für die Emulgatoren gegenüber, der bisher eine weitere Verwendung verhindert hat.A disadvantage of the advantages mentioned is the relatively high price for the Emulsifiers opposite, which previously prevented further use Has.
Für Stationär-Motoren fällt die Forderung i. B. auf ein kältefestes Verhalten weg.The requirement for stationary motors is i. B. on a cold resistant Behavior away.
Damit lassen sich andere Arten von Kraftstoff-Wasser-Gemischen einsetzen.This allows other types of fuel-water mixtures deploy.
Die Konditionierung des Kraftstoffes über die bekannten und allgemein üblichen Methoden hinaus (Verdichten, intensives Mischen mit Luft usw.) wird unmittelbar vor dem Verbrennungsvorgang mit aus der Verbrennungskraftmaschine zur Verfügung stehenden oder leicht gewinnbaren Aggregatzuständen von preiswerten Hilfsstoffen vorgenommen. Der Prozeß wird so geführt, daß für den Verbrennungsvorgang keine Energieeinbuße, sondern - soweit möglich - ein Energiegewinn entsteht.The conditioning of the fuel over the known and general usual methods (compression, intensive mixing with air, etc.) is from the internal combustion engine immediately before the combustion process available or easily obtainable Physical states made of inexpensive auxiliary materials. The process is carried out in such a way that there is no loss of energy for the combustion process, but - as far as possible - energy is generated.
Anhand eines Diesel-Motors sei das Prinzip erläutert (Bild 1):The principle is explained using a diesel engine ( Figure 1):
Um die Vorteile des Diesel-Öl-Emulsionskraftstoffes mit z. B. 20% Wasser-Gehalt nutzen und die hohen Kosten für den Emulgator zu vermeiden, wird vor der Einspritzpumpe eine Mischkammer angeordnet, in der das Diesel-Öl mit Wasser dadurch intensiv gemischt wird, daß über einen um das Abgassammelrohr angeordneten Wärmetauscher Wasserdampf mit dem gewünschten Druck in die Mischkammer eingedüst wird. Hier kondensiert der Wasserdampf in kleinsten Tröpfchen im Dieselöl und bildet - begünstigt durch Verwirbelung - eine Emulsion, die dem Motor über die Einspritzpumpe zugeführt wird.To take advantage of the diesel oil emulsion fuel with z. B. 20% Use water content and the high cost of the emulsifier too avoid, a mixing chamber is arranged in front of the injection pump which the diesel oil is mixed with water intensely that over a water vapor arranged around the exhaust manifold with the desired pressure is injected into the mixing chamber. Here the condenses Water vapor in the smallest droplets in the diesel oil and forms - favored by swirling - an emulsion that the engine via the injection pump is fed.
Die Mischkammer kann pro Motor oder pro Zylinder vorgesehen werden und so ausgelegt sein, daß insgesamt eine geringere oder stärkere Aufheizung des Treibstoffgemisches erfolgt.The mixing chamber can be provided per engine or per cylinder and be designed so that overall less or more heating of the fuel mixture.
Anstelle der Mischkammer vor der Einspritzpumpe ist auch ein rel. enges Mischrohr zwischen Einspritzpumpe und Zylinder möglich.Instead of the mixing chamber in front of the injection pump, a rel. narrow Mixing tube between injection pump and cylinder possible.
Eine weitere Möglichkeit stellt eine Spezialmischdüse unmittelbar am Zylinder dar.Another option is a special mixing nozzle directly on the Cylinder.
1. Unmittelbar am Motor bzw. Einzelzylinder angeordnete Konditionierungseinrichtungen gestatten eine einfache, dem jeweiligen Zweck angepaßte Kraftstoff- oder Verbrennungsluft-Konditionierung ohne relativ teure Hilfsstoffe.1. Located directly on the engine or single cylinder Conditioning devices allow simple, each Purpose-adjusted fuel or combustion air conditioning without relatively expensive auxiliaries.
2. Die Konditionierung kann so erfolgen, daß der Energiegehalt pro Verbrennungsvorgang nicht verkleinert wird.2. The conditioning can be done so that the energy content per Combustion process is not reduced.
3. Die Konditionierung ist flexibel und kann z. B. Lastzuständen usw. angepaßt werden.3. The conditioning is flexible and can e.g. B. load conditions, etc. are adjusted.
