Abstract
Description
[0001] Das Kraftstoffverdampfungssystem hat das Einsparen von Kraftstoff, bei von Verbrennungsmotoren und Turbinen betriebenen Fortbewegungsmitteln, zum Zweck. The fuel evaporation system has the purpose of saving fuel in locomotives powered by internal combustion engines and turbines.
Aufbau und FunktionsprinzipStructure and functional principle
[0002] Das Kraftstoffverdampfungssystem wird zwischen Motor und Auspuffanlage montiert. The fuel evaporation system is mounted between the engine and exhaust system.
[0003] Eingesetzt, bei einem 4-Zylinder-Motor, können 4 Systeme eingebaut werden. Used, in a 4-cylinder engine, 4 systems can be installed.
[0004] Der Kraftstoff 1, zum Beispiel Benzin, wird in das Kraftstoffverdampfungssystem gepumpt. The fuel 1, for example gasoline, is pumped into the fuel evaporation system.
[0005] Der Kraftstoff 1 fliesst in eine Verdampfungsspirale 2, die fest auf dem Abgasrohr 6 aussen aufgezogen ist. The fuel 1 flows into an evaporating coil 2, which is fixed externally on the exhaust pipe 6.
[0006] In dieser Verdampfungsspirale 2 wird der Kraftstoff 1 erhitzt 3 und in Dampfform 4 gebracht und wird dem Motor zugeführt. In this evaporating coil 2, the fuel 1 is heated 3 and brought into vapor form 4 and is supplied to the engine.
[0007] Die heissen Abgase 5 und 7 strömen durch das Kraftstoffverdampfungssystem und erhitzen/verdampfen den Kraftstoff 1, der in der Verdampfungsspirale 2 nach oben fliesst; ein Kreislauf entsteht. Der Kraftstoff 1 nimmt Wärme auf 3 und die Abgase 5 und 7 geben Wärme ab. The hot exhaust gases 5 and 7 flow through the fuel evaporation system and heat / vaporize the fuel 1 flowing in the evaporating coil 2 upwards; a cycle is created. The fuel 1 absorbs heat 3 and the exhaust gases 5 and 7 release heat.
[0008] Das Kraftstoffverdampfungssystem ist von einer Temperaturbeständigen Isolationsschicht 8 ummantelt. The fuel evaporation system is covered by a temperature-resistant insulating layer 8.
[0009] Bei den heutigen Motoren die etwas bewegen, wird der Kraftstoff bei Umgebungstemperaturen in den Verbrennungsprozess eingeleitet, um die gewünschte Bewegungsenergie zu erzielen. Bei diesen chemischen und physikalischen Prozessen wird nur die Druckenergie, die bei der Explosion durch Entzünden des Luft/Kraftstoff-Gemisches entsteht, genutzt. Doch die Wärmeenergie, die bei der chemischen Reaktion entsteht, wird einfach über Krümmer und Abgasanlage, abgeleitet. Das Kraftstoffverdampfungssystem nutzt diese Energie, um die abgeleitete Wärmeenergie umzulagern, die der zufliessende Kraftstoff aufnehmen wird. Durch diese Aufnahme vergrössert der Kraftstoff sein Volumen um ein Vielfaches, bis er in Dampfform oder Gasform übergeht. Er nimmt Startenergie auf und es entsteht ein Wärmekreislauf zwischen abgeleitenden Abgasen und zufliessendem Kraftstoff. Der dampfförmige heisse Kraftstoff oder energiegeladene Kraftstoff gelangt in das Verbrennungssystem des Motors. In today's engines that move something, the fuel is introduced at ambient temperatures in the combustion process to achieve the desired kinetic energy. These chemical and physical processes use only the pressure energy generated by the explosion of the air / fuel mixture during the explosion. But the heat energy, which arises in the chemical reaction, is simply derived via elbow and exhaust system. The fuel vaporization system uses this energy to relocate the dissipated heat energy that the incoming fuel will absorb. Through this recording, the fuel increases its volume many times, until it goes into steam or gaseous form. It absorbs starting energy and creates a heat cycle between the exhaust gases and the incoming fuel. The vaporous hot fuel or energized fuel enters the combustion system of the engine.
Chemischer Vorteil des KraftstoffverdampfungssystemsChemical advantage of the fuel evaporation system
[0010] Der Verbrennungsprozess im Zylinderraum ist eine Chemische Reaktion und die Temperatur spielt eine wichtige Rolle dabei. Dazu die unten beschriebene RGT-Regel: Die RGT-Regel (Reaktionsgeschwindigkeit-Temperatur-Regel) ist eine Faustregel in der Biochemie, Biologie, Geologie und Physiologie. Sie besagt, dass sich die Reaktionsgeschwindigkeit verdoppelt, wenn die Temperatur um 10 Kelvin, 10 Grad erhöht wird. The combustion process in the cylinder chamber is a chemical reaction and the temperature plays an important role. The RGT rule described below: The RGT Rule (Reaction Rate Temperature Rule) is a rule of thumb in biochemistry, biology, geology and physiology. It states that the reaction rate doubles when the temperature is increased by 10 Kelvin, 10 degrees.
[0011] Das heisst, wenn der Kraftstoff heiss zudosiert wird, reagiert er schneller mit der Luft (Sauerstoff) und das wiederum bedeutet, es kann mit weniger Kraftstoff dieselbe kinetische Energie erzeugt werden wie beim normalen Einspritzverfahren, das mehr Kraftstoff verbraucht. That is, when the fuel is metered hot, it reacts faster with the air (oxygen) and that in turn means it can be produced with less fuel the same kinetic energy as in the normal injection process, which consumes more fuel.
Physikalischer Vorteil des KraftstoffverdampfungssystemsPhysical advantage of the fuel evaporation system
[0012] Durch die Verdampfung des Kraftstoffes, maximale Volumen-Ausdehnung, kann das Zudosieren effizienter umgesetzt werden. Die Molekulardichte ist viel geringer als im flüssigen Zustand. By the evaporation of the fuel, maximum volume expansion, the metering can be implemented more efficiently. The molecular density is much lower than in the liquid state.
Form des KraftstoffverdampfungssystemsShape of the fuel evaporation system
[0013] Das Kraftstoffverdampfungssystem hat keine bestimmte Form, es muss auf die verschiedenen Motorentypen angepasst werden. Das Prinzip bleibt das gleiche. The fuel evaporation system has no particular shape, it must be adapted to the different engine types. The principle remains the same.
Einsatzmöglichkeitenapplications
[0014] Bei flüssig/Gas, Verbrennungsmotoren, die in Autos, LKWs, Schiffen sowie Flugzeugen, Booten, die mit Benzin, Diesel, Kerosin, Methanol und Gas betrieben werden. Turbinen-angetriebene Fahrzeuge, Fluggeräte und Öl-Heizungen können auch, damit ausgerüstet werden. For liquid / gas, internal combustion engines that are used in cars, trucks, ships and aircraft, boats that run on gasoline, diesel, kerosene, methanol and gas. Turbine-powered vehicles, aircraft and oil heaters can also be equipped with it.
