Abstract
Description
Die Erfindung betrifft einen Reformer von Verbrennungsabgasen, bei dem das vorzugsweise aus Edelstahl bestehende Reformergehäuse mit mindestens einer Versorgungsleitung mit der Abgasanlage und mit mindestens einer Versorgungsleitung mit der Ansaugvorrichtung, insbesondere einer Verbrennungskraftmaschine, verbunden ist, wobei sich im Reformergehäuse vorzugsweise ein erfindungsgemässes Diffusionselement befindet, das mittig im Reformergehäuse aussenwandig mit der Reformergehäuse-Innenwand verschweisst ist, wodurch das Reformerinnen-Gehäuse, in eine Abgaszuströmkammer und in eine Reformatgas-Sammelkammer geteilt ist, wodurch bei der in Betrieb befindlichen Verbrennungskraftmaschine unterdruckbedingt anfallende heisse Verbrennungsabgase über die Abgaszuströmkammer, durch das Diffusionselement in die Reformatgas-Sammelkammer strömen und von dort aus als kaltes wasserstoffhaltiges Reformatgas in den Verbrennungsprozess der Verbrennungskraftmaschine eingeleitet werden.The The invention relates to a reformer of combustion exhaust gases, in which preferably made of stainless steel reformer housing with at least a supply line with the exhaust system and with at least a supply line with the suction device, in particular an internal combustion engine, wherein in the reformer housing preferably an inventive Diffusion element is the outside in the middle of the reformer housing with the reformer housing inner wall is welded, whereby the reformer housing, in an exhaust gas inlet chamber and divided into a reformate gas collection chamber, whereby at the operating internal combustion engine under pressure accumulating hot combustion exhaust gases via the Abgaszuströmkammer, through the diffusion element in the reformate gas collection chamber and flow from there as a cold hydrogenated reformate gas in the combustion process the internal combustion engine are initiated.
Das erfindungsgemässe Diffusionselement besteht vorzugsweise aus einem palladiumbeschichteteten Edelstahlgehäuse, in dem sich mit einer Hochdruck-Presse verdichtete insbesondere palladiumbeschichtete Edelstahlwolle befindet, wobei der Gehäuseboden und der Gehäusedeckel des Diffusionselementes mit Gasdurchlass-Spalten versehen sind. Die Gasdurchlass-Spalten wurden dadurch geschaffen, dass der Gehäuseboden und der Gehäusedeckel in mehrere Bleche geteilt wurden. Danach wurden diese Bleche wie bei einem Puzzle zusammengesetzt und mit mehreren Schweisspunkten wieder zu einem Blech verschweisst. Die zwischen den Schweisspunkten verbleibenden Spalten sind die Gasdurchlass-Spalten.The invention Diffusion element is preferably made of a palladium coated Stainless steel housing, in which is with a high pressure press compacted especially palladium-coated stainless steel wool located the case bottom and the housing cover of the diffusion element are provided with gas passage columns. The gas passage columns were created by the housing bottom and the housing cover divided into several sheets. After that, these sheets were like composed in a puzzle and with multiple welding points welded back to a sheet metal. The between the welding points remaining columns are the gas passage columns.
Durch den in der Ansaugvorrichtung herrschenden Unterdruck werden heisse Verbrennungsabgase abgesaugt und dabei in Kontakt mit der Palladiumbeschichtung des Diffusionselementes gebracht, wobei ab einer Temperatur von 200°C heisses wasserstoffhaltiges Reformatgas entsteht, das, sobald es das Diffusionselement passiert hat, extrem abgekühlt dem Verbrennungsprozess der in Betrieb befindlichen Verbrennungskraftmaschine als ein ergänzender Treibstoff zugeführt wird.By the pressure prevailing in the suction negative pressure are hot Extracted combustion exhaust gases while in contact with the palladium coating brought of the diffusion element, wherein from a temperature of 200 ° C hot Hydrogen-containing reformate gas is formed, which, once it's the diffusion element happened, extremely cooled the combustion process of the internal combustion engine in operation as a supplementary Fuel supplied becomes.
Zur Gasstrom-Feindosierung ist jeder Versorgungsleitung mindestens ein Regelventil vor- und/oder nachgeschaltet.to Gas flow metering is at least one supply line Control valve upstream and / or downstream.
Hintergrund der Erfindungbackground the invention
Es ist bekannt, dass sich in den heissen Verbrennungsabgasen, insbesondere einer Verbrennungskraftmaschine, ungenutzte Energien befinden. Diese ungenutzten Energien gilt es technisch zu nutzen.It It is known that in the hot combustion gases, in particular an internal combustion engine, unused energies are located. These Unused energies must be used technically.

Erfindungsgemässe AufgabeTask according to the invention
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, auf eine sehr einfache Art, einen sehr kostengüstigen und leicht nachrüstbaren Reformer von Verbrennungsabgasen zu schaffen, um eine optimale Energiemenge, insbesondere aus den heissen Verbrennungsabgasen einer Verbrennungskraftmaschine, abzuzweigen und diese Energie der Ansaugvorrichtung der Verbrennungskraftmaschine, durch eine Versorgungsleitung hindurch, ergänzend als zusätzlichen Brennstoff zuzuführen.Of the in claim 1 protection invention is based on the problem in a very simple way, a very cost-effective and easy to retrofit Reformer of combustion exhaust gases to provide an optimal amount of energy, in particular from the hot combustion exhaust gases of an internal combustion engine, branch off and this energy of the intake of the internal combustion engine, through a supply line, in addition as additional To supply fuel.
Erfindungsgemässe LösungSolution according to the invention
Die erfindungsgemässe Lösung besteht darin, dass im Reformergehäuse ein Diffusionselement angeordnet ist, das einerseits an die Abgaseinlass-Kammer und andererseits an eine Reformatgassammel-Kammer grenzt, wobei eine in der Abgaseinlass-Kammer befindliche Abgaszuström-Öffnung über eine Abgasversorgungsleitung mit dem Abgasstrang verbunden ist und eine in der Reformatgassammel-Kammer befindliche Reformatgasabström-Öffnung über eine Reformatgas-Versorgungsleitung mit dem Ansaugtrakt verbunden ist, wobei die Druckdifferenz zwischen der Abgasvorrichtung und dem Ansaugtrakt das aus dem heiss genutzten Reformer anfallende Reformatgas dem Ansaugtrakt, insbesondere einer Verbrennungskraftmaschine, als ergänzenden Brennstoff zuführt.The invention solution is that arranged in the reformer housing a diffusion element is, on the one hand to the exhaust gas inlet chamber and on the other adjacent to a reformate gas collection chamber, one in the exhaust gas inlet chamber located Abgaszuström opening via a Exhaust gas supply line is connected to the exhaust line and a Reformatgasabström opening located in the Reformatgassammel chamber via a Reformatgas supply line is connected to the intake tract, wherein the pressure difference between the exhaust device and the intake tract the resulting from the hot reformer used reformate the Intake tract, in particular an internal combustion engine, as a supplementary Supplying fuel.
