Description

Die Erfindung betrifft eine Vorrichtung zur Verringerung der Schadstoffemission von insbesondere fossile Brennstoffe verbrennenden Energieumwandlungsmaschinen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for reducing the emission of pollutants especially fossil fuel burning energy conversion machines according to the preamble of claim 1.

Auf Grund des zunehmenden Bewußtseins für die Gefährdung der Umwelt ist die Schadstoffemission einer Energieumwandlungsmaschine, die beispielsweise eine Brennkraftmaschine oder eine Strom- bzw. Wärmegewinnungsanlage sein kann, ein wesentlicher Indikator für die Entscheidung über die Brauchbarkeit einer derartigen Maschine. In der Praxis ist deshalb bereits eine Reihe von Maßnahmen bekannt, die zu einer Verringerung der Schadstoffemission beitragen. Diese lassen sich in zwei grundsätzlich voneinander verschiedene Arten unterteilen: zum einen diejenigen Maßnahmen, die bei der Abgasbehandlung ansetzen, wie beispielsweise die Anbringung eines geregelten Katalysators im Abgasstrang einer Brennkraftmaschine, und zum anderen diejenigen Maßnahmen, die bei der Brennstoffvorbereitung ansetzen. Die zuletzt genannten Maßnahmen sollen vor allen Dingen eine bessere Aufbereitung des Brennstoff-Luft-Gemisches erreichen. Auch hierfür sind in der Praxis bereits Lösungen vorgeschlagen worden, die jedoch alle einen verhältnismäßig komplizierten Aufbau bzw. einen aufwendigen Regelmechanismus aufweisen. Due to the increasing awareness of the danger to the environment, the Pollutant emission from an energy conversion machine, for example a Internal combustion engine or a power or heat recovery system can be a essential indicator for the decision on the usability of such Machine. A number of measures are therefore already known in practice contribute to a reduction in pollutant emissions. These can be divided into two subdivide fundamentally different types: firstly those Measures that start with exhaust gas treatment, such as the Mounting a regulated catalyst in the exhaust line of an internal combustion engine, and on the other hand those measures that are involved in fuel preparation start. The last-mentioned measures should above all be a better one Reach the preparation of the fuel-air mixture. For this too are in the Practical solutions have already been proposed, but all are proportionate complicated structure or a complex control mechanism exhibit.

Aus dem deutschen Gebrauchsmuster 84 25 170 ist eine Vorrichtung zur Herabsetzung des Brennstoffverbrauchs von Brennkraftmaschinen bekannt, bei der ein stabförmiger Permanentmagnet parallel zu der Brennstoffleitung ausgerichtet an der Brennstoffleitung angebracht ist. Hierbei sind Nord- und Südpol des Permanentmagneten in Strömungsrichtung des Brennstoffs in vorstehend genannter Reihenfolge aufeinanderfolgend angeordnet. Bei dieser bekannten Vorrichtung hat es sich als nachteilig erwiesen, daß durch Erschütterungen oder sonstige äußere Einflüsse der Wirkungsgrad dieser bekannten Vorrichtung herabgesetzt wird.From the German utility model 84 25 170 is a device for Reduction in the fuel consumption of internal combustion engines known at a rod-shaped permanent magnet aligned parallel to the fuel line is attached to the fuel line. Here are the north and south poles of the Permanent magnets in the flow direction of the fuel in the aforementioned Sequence arranged sequentially. Has in this known device it has proven to be disadvantageous that vibrations or other external Influences the efficiency of this known device is reduced.

Aus der DE-A-42 29 594 geht ein Verfahren sowie eine Vorrichtung zum elektromagnetischen Behandeln eines Fluids hervor, bei dem das Fluid dem Feld zweier, mit Rechteckspannung beaufschlagter, in Achsrichtung hintereinander angeordneter Spulen ausgesetzt ist. Dabei wird an jede der Spulen eine gesonderte Rechteckspannung angelegt, die gegeneinander phasenverschoben sind. Dadurch ergeben sich erhebliche Verbesserungen bei der magnetischen Wasserbehandlung, insbesondere was den Kalkausfall und die Kalkauflösung, aber auch was die Nitratbelastung des Wassers betrifft.DE-A-42 29 594 describes a method and a device for electromagnetic Treating a fluid in which the fluid has the field of two, with Rectangular voltage applied to coils arranged one behind the other in the axial direction is exposed. A separate square-wave voltage is applied to each of the coils, that are out of phase with each other. This results in significant improvements in the magnetic water treatment, in particular what the lime precipitation and the lime solution, but also with regard to the nitrate pollution of the water.

Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, die unabhängig von den Einsatzbedingungen bei einem einfachen Aufbau einen hohen Wirkungsgrad aufweist.It is an object of the present invention, a device of the beginning to create the type mentioned, regardless of the operating conditions at a simple structure has a high efficiency.

Die vorstehende Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Die Induktivität, die beispielsweise ein Elektromagnet in Form einer stromdurchflossenen Spule sein kann, erzeugt hierbei ein magnetisches Feld, das unabhängig von äußeren Einflüssen auf den durch die Brennstoffleitung strömenden Brennstoff einwirkt. Durch diese Anordnung kann den Molekülen der Kohlenstoffketten Energie zugeführt werden. Dadurch wird im Zusammenhang mit Sauerstoff eine bessere Verbrennung erreicht. Durch Erhöhung des Wirkungsgrades bei der Verbrennung tritt eine merkliche Schadstoffminderung ein, wobei gleichzeitig eine Kraftstoffreduzierung erreicht wird. Darüber hinaus kann die Oberflächenspannung des Brennstoffs sinken und es zu einer Verbesserung der Gemischbildung mit hierdurch bewirkter optimaler Verbrennung kommen. Dabei können die eine unausgewogene Ladungsverteilung aufweisenden Moleküle des Brennstoffs entsprechend dem Magnetfeld ausgerichtet werden, so daß die Ladungsverteilung der Moleküle wieder ausgewogen ist. Hierdurch läßt sich zum einen die Schadstoffemission reduzieren, die beispielsweise bei nach dem Otto-Prinzip arbeitenden Brennkraftmaschinen zu einer CO-Verminderung und bei nach dein Diesel-Prinzip arbeitenden Brennkraftmaschinen zu einer Rußverringerung führt. Zum anderen kann gleichzeitig eine Brennstoffersparnis erzielt werden, da die Verbrennung in der Energieumwandlungsmaschine optimal erfolgt.The above object is achieved by the features of claim 1. The Inductance, for example an electromagnet in the form of a current Coil can generate a magnetic field that is independent from external influences on the fuel flowing through the fuel line acts. This arrangement allows the molecules of the carbon chains to have energy be fed. This will make a better one in connection with oxygen Combustion reached. By increasing the efficiency of combustion there is a noticeable reduction in pollutants, while at the same time reducing fuel is achieved. In addition, the surface tension of the Fuel decrease and there is an improvement in the mixture formation with this optimal combustion. This can be an unbalanced Molecules of the fuel with charge distribution corresponding to the Magnetic field are aligned so that the charge distribution of the molecules again is balanced. On the one hand, this can reduce pollutant emissions, which, for example, in internal combustion engines working according to the Otto principle a reduction in CO and in internal combustion engines working according to the diesel principle leads to a reduction in soot. On the other hand, one can Fuel savings can be achieved because of the combustion in the energy conversion machine done optimally.

Die Induktivität kann auf ganz unterschiedliche Weise an der Brennstoffleitung vorgesehen werden. So besteht beispielsweise die Möglichkeit, daß ein Hart-PVC-Rohrsystem vorgesehen ist, dem eine oder mehrere Induktivitäten zugeordnet sind. Dabei haben die Induktivitäten keine mechanische Verbindung mit dem durchfließenden Kraftstoff im Rohrsystem. Der die Induktivität bildende Elektromagnet kann ebenfalls auf beliebige Art und Weise an der Brennstoffleitung angebracht werden. So besteht beispielsweise die Möglichkeit, daß er seitlich an der Außenseite der Brennstoffleitung angeordnet wird. Eine in ihrer Wirkung besonders optimale Lösung sowie ein kompakter Aufbau ergibt sich dadurch, daß der Elektromagnet eine stromdurchflossene Spule ist, die die Brennstoffleitung konzentrisch umgibt.The inductance can be in very different ways on the fuel line be provided. For example, there is the possibility that a hard PVC pipe system is provided, to which one or more inductors are assigned. The inductors have no mechanical connection with the flowing one Fuel in the pipe system. The electromagnet that forms the inductance can also be attached to the fuel line in any way become. For example, there is the possibility that it is on the side of the Outside of the fuel line is arranged. One with a special effect optimal solution and a compact structure results from the fact that the Electromagnet is a current-carrying coil that runs through the fuel line concentrically surrounds.

Damit die Spule vor äußeren Einflüssen, wie beispielsweise korrosiven Medien, mechanischen Beschädigungen usw. geschützt wird, kann weiterhin vorgesehen sein, daß der Elektromagnet in einem Gehäuse, vorzugsweise aus Hart-PVC angeordnet wird. Hierbei können Gehäuse und Elektromagnet so ausgebildet sein, daß sie über die Brennstoffleitung als kompakte Einheit geschoben werden können. Es besteht aber auch die Möglichkeit, daß in den Elektromagneten ein Durchflußrohrstück eingeschoben wird, welches an beiden Enden jeweils mit einem in die jeweilige Stirnwand des Gehäuses eingesetzten und mit dem Durchflußrohrstück verbundenen Anschlußstutzen versehen ist. Hierdurch wird eine kompakte Einheit gebildet, die dann in eine Brennstoffleitung einer Energieumwandlungsmaschine eingesetzt werden kann. Somit können nicht nur neue Energieumwandlungsmaschinen mit der erfindungsgeinäßen Vorrichtung versehen werden, sondern es lassen sich auch bereits im Einsatz befindliche Energieumwandlungsmaschinen mit der erfindungsgemäßen Vorrichtung nachrüsten.So that the coil is protected from external influences, such as corrosive media, mechanical damage, etc. is protected, can still be provided be that the electromagnet in a housing, preferably made of hard PVC is arranged. The housing and electromagnet can be designed that they can be pushed over the fuel line as a compact unit. But there is also the possibility that a flow tube piece in the electromagnet is inserted, which at both ends with one in the each end wall of the housing used and with the flow tube piece connected connecting piece is provided. This makes a compact unit formed, which then in a fuel line of an energy conversion machine can be used. Thus, not only new energy conversion machines can be provided with the device according to the invention, but it can also be used with energy conversion machines already in use retrofit the device according to the invention.

Dem Elektromagneten können Spannungen zugeführt werden, wobei die Wahl der Spannungshöhe, des Spannungsverlaufs usw. nach den Einsatzbedingungen der Vorrichtung wählbar sein können. Um dies zu erreichen, kann der Elektromagnet vorzugsweise über ein abgeschirmtes Kabel mit einer Steuereinrichtung verbunden sein, mittels der die verschiedenen Parameter der Spannung einstellbar sind. Je nach Einsatzverwendung kann dabei die Steuereinrichtung angeordnet werden. So besteht beispielsweise die Möglichkeit, daß die Steuereinrichtung in dem Fahrerhaus eines Lastkraftwagens oder dgl. angeordnet ist.Voltages can be supplied to the electromagnet, the choice of Voltage level, the voltage curve, etc. according to the operating conditions of the Device can be selectable. To achieve this, the electromagnet preferably connected to a control device via a shielded cable by means of which the various parameters of the voltage can be set. Each the control device can be arranged after use. So there is, for example, the possibility that the control device in the Driver's cab of a truck or the like is arranged.

Besonders vorteilhaft ist es, wenn der Elektromagnet mit einer Steuereinrichtung verbunden ist, die vorzugsweise einen Oszillator aufweist, der der Induktivität bzw. dem Elektromagneten eine oszillierende Spannung zuführt, wobei dem Sägezahnimpuls ein konstanter Gleichstrom überlagerbar ist. Es ist besonders vorteilhaft, wenn die oszillierende Spannung eine Sägezahnform besitzt, die vorzugsweise einen Betrag von 12-24 Vss, insbesondere von 24 Vss aufweisen kann. Weiterhin hat es sich als vorteilhaft erwiesen, wenn der Sägezahnimpuls eine Frequenz von ca. 500 Hz besitzt. Ggf. kann ein nachgeschalteter Leistungsverstärker vorgesehen sein, mit dem diese Impuls-Stromsteuerung auf die Induktivität des vorzugsweise vorhandenen Rohrsystems gegeben wird.It is particularly advantageous if the electromagnet is connected to a control device, which preferably has an oscillator that supplies an oscillating voltage to the inductor or the electromagnet, wherein a constant direct current can be superimposed on the sawtooth pulse. It is particularly advantageous if the oscillating voltage has a sawtooth shape, which can preferably have an amount of 12-24 V ss , in particular 24 V ss .

Eine mögliche Betriebsweise der vorgeschlagenen Lösung kann also so aussehen, daß der Oszillator der Steuerelektronik einen Sägezahnimpuls mit einer Frequenz von ca. 500 Hz erzeugt. Dieser Sägezahnimpuls wird auf einen konstanten Gleichstrom gelegt. Durch den ggf. nachgeschalteten Leistungsverstärker wird diese Impuls-Stromsteuerung auf die Induktivität eines die Brennstoffleitung enthaltenden Rohrsystems gegeben.

Ebenso ist es vorteilhaft, wenn die Vorrichtung zur Herabsetzung des Brennstoffverbrauches und der CO-Minderung bei Ottomotoren eingesetzt wird, welche mit Benzin betrieben werden. Ebenso kann aber die erfindungsgemäße Vorrichtung in vorteilhafter Weise zur Herabsetzung des Heizölverbrauches in ölbefeuerten Heizanlagen wie auch zur Herabsetzung des Dieselölverbrauchs bei Anwendung in Blockheizkraftwerken eingesetzt werden. In den zuletzt genannten Fällen ist es von Vorteil, wenn die erfindungsgemäß Vorrichtung für eine Stromversorgung für 220 V/50 Hz ausgelegt ist. Bei einem Einsatzim Zusammenhang mit Verbrennungsmaschinen für Dieselbrennstoffe bzw. für Benzin, die nach dem Otto-Prinzip arbeiten, ist es von vorteil, wenn das Gerät für ein Niederspannungsbereich von 12-24 V ausgelegt ist.Basically, there is a possibility that the proposed device both for the low voltage range of 12-24 V as well as for a power supply can be designed for 220 V / 50 Hz. It is particularly advantageous if the Device for reducing soot formation or soot reduction Simultaneous fuel saving on internal combustion engines for diesel fuels is used.

Weiterhin kann vorgesehen sein, daß der der Energieumwandlungsmaschine zuzuführende Brennstoff vor der Zuführung erwärmt wird. Diese Erwärmung erfolgt durch eine Heizeinrichtung, die an oder in der Brennstoffleitung vorgesehen ist.Furthermore, it can be provided that that of the energy conversion machine fuel to be supplied is heated before the supply. This warming takes place by a heater provided on or in the fuel line.

Für das wärmeabgebende Medium können hierbei wiederum die unterschiedlichsten Lösungen vorgesehen werden. Da die Energieumwandlungsmaschine selbst während ihres Betriebes eine hohe Temperatur erreicht und deshalb ein die entstandene Wärme abführender Kühlkreislauf mit einem Kühlmedium, vorzugsweise Wasser vorgesehen sein kann, ist es vorteilhaft, wenn für das erhitzte, wärmeabgebende Medium das Kühlmedium der Energieumwandlungsmaschine Verwendung findet. Es ist deshalb besonders vorteilhaft, wenn der Wärmetauscher in den Kühlkreislauf der Energieumwandlungsmaschine eingeschaltet ist.For the heat-emitting medium, a wide variety can be used Solutions are provided. Because the energy conversion machine itself reaches a high temperature during its operation and therefore a Heat dissipating cooling circuit with a cooling medium, preferably Water can be provided, it is advantageous if for the heated, heat-emitting medium is the cooling medium of the energy conversion machine Is used. It is therefore particularly advantageous if the heat exchanger is switched on in the cooling circuit of the energy conversion machine.

Als besonders vorteilhaft hat es sich erwiesen, wenn der Brennstoff auf eine Temperatur von ca. 40° C erwärmt wird.The amount of warming can also vary depending on the circumstances of the individual case can be determined. It has proven to be particularly advantageous when the fuel is heated to a temperature of approx. 40 ° C.
