Definitions

  • the invention relates to a device for reforming hydrocarbons of a fuel, said device being provided with a fuel supply, a reaction chamber connected to said supply and being provided with one or more catalysts or not, an outlet from said reaction chamber to an internal combustion engine and heat exchanger means between the reaction chamber and a source of heat .
  • a device for reforming hydrocarbons of a fuel, said device being provided with a fuel supply, a reaction chamber connected to said supply and being provided with one or more catalysts or not, an outlet from said reaction chamber to an internal combustion engine and heat exchanger means between the reaction chamber and a source of heat .
  • a fuel e.g. gasoline
  • additives such as cyclic hydrocarbons and lead compounds
  • the object of the invention is to provide a device that does not have said disadvantages, that has a relatively simple structure and that can be used with the most common types of fuel, available at gas stations, for automobiles, thus fuels with additives.
  • a further object of the invention is to gasify at least a part of the fuel during reformation of the fuel, in order to achieve a further improvement of the combustion.
  • the reaction chamber comprises at least one cham- ber, means for generating a flow pattern in the fuel being provided on at least one location.
  • said means are designed such, that a vortex can be generated in the fuel.
  • the fuel or the mixture of fuel and oxygen-carrying gas follows a relatively long path in relation to the length of the chamber, in which the vortex creates a radial distribution of the various hydrocarbon molecules and particularly the larger, heavier hydrocarbon molecules to be reformed are forced against the reaction chamber wall by the centripetal force.
  • This has the advantage, that the transfer of heat from the chamber wall to the hydrocarbon molecules also substantially occurs in the direction of exactly the larger hydrocarbon molecules.
  • a further advantage is the fact that by conveying the larger hydrocarbon molecules in a vortex along the reaction chamber wall, they can not only be reformed by a thermal process and, if provided, by the catalytic action of the reaction chamber wall, but also by mechanical action. Not only the friction of said larger hydrocarbon molecules along the wall contributes to the reformation of said molecules, but also the heat generated with it as a consequence of the vortex. Of great importance is the cleaning action by friction which the fuel or fuel/air mixture brought in a vortex can exert on the reaction chamber wall(s) . This provides for continuous removal of the deposit caused by the additives in the fuel, as a result of which the catalytic action of the reaction chamber wall or catalyst separately mounted on it, will not or only partly reduced.
  • the reaction chamber is incorporated in the fuel supply to the internal combustion engine preceding a mixing member at which the fuel can be mixed with an oxygen-carrying gas.
  • This has the essential advantage that reformation of the fuel can be safely performed at a higher temperature than would be possible with a mixture of a fuel and an oxygen- carrying gas . This allows for a better division in shorter hydrocarbon chains and at least a part of the fuel can be brought into the gaseous phase, depending completely or partly on the temperature .
  • the reaction chamber comprises at least two coaxial tube parts with at least one helical duct being provided between said tube parts.
  • a helical duct is realized by making a helical groove of rib in one of the tubes.
  • the reaction chamber consists of a tube being received in a housing and being at least partly helical, in which the helical tube is part of a wall of an orifice for a heating medium, mounted in the housing.
  • the helical duct or tube can additionally contain guiding members also having a helical shape, as a result of which a second helical flow pattern is superimposed on the first flow pattern.
  • a simple embodiment consists of coaxial tubes in which the connections for supply and dis- charge of the fuel to and from the reaction chamber have been provided and in which the liquid medium used for heating is led through the inner tube.
  • the liquid medium used for heating can flow along both sides of the reaction chamber.
  • the connections for the fuel to be reformed must be led through the outer tube liquid-tight.
  • the tube partly forms an orifice for a heating medium, made in the housing. Then the housing provides for transfer of heat to the part of the housing which is not in direct contact with the medium.
  • a liquid medium for heating instead of using a liquid medium for heating, one can of course also work with a gaseous medium, such as the exhaust gases of the internal combustion engine.
  • reaction cham- ber can also be at least partly received in, or be part of, an engine block or exhaust system.
  • the reaction chamber could be completely or partly integrated in an engine block or manifold during their manufacture.
  • reaction chamber in the fuel supply to the internal combustion engine, behind a mixing member where the fuel can be mixed with an oxygen-carrying gas.
  • the embodiments described above can be applied, but also ones with tube portions to be mounted on or in an exhaust pipe or exhaust manifold.
  • a reaction chamber composed of such tube portions, it can consist of one or a number of subsequent tube portions, or of two or more tube portions mounted in parallel, in which latter case means for openingen or closing at least one of said tube portions are provided.
  • the tube portions will then contain one or more guiding members, the guiding member being substantially a helicoidal guiding member or consisting of a number of helicoidal guiding members mounted coaxially.
  • the invention also provides for an embodiment of the reaction chamber in which the reformation of a fuel is established by a more mechanical action.
  • the reaction chamber comprises at least one elongated duct having one or more square transitions.
  • a duct comprises a number of subsequent parts extending in opposite direction, with the ends of the parts of the duct, contrary to the ends of the duct, end into recesses provided in end plates.
  • the inlet and outlet for the fuel are provided at the same end plate or on opposite end plates.
  • the underlying thought is that by passing the fuel through the duct(s) at high velocity, the impulse force and changes in velocity occuring when the fuel hits the end plates will cause the hydrocarbon chains to be at least partly divided into smaller chains. Heating is necessary and the use of catalytically acting materials and application of a helicoidal guiding member in the air inlet can provide a further improvement of the process.
  • Heating can take place by heating the parts of the duct enclosed between the end plates . According to a further elaboration, this can be achieved by mounting a tube around the reaction chamber, in which the end plates will close the tube at both sides and in which the tube or end plates are provided with an inlet and outlet for a liquid medium which is to provide heating. It goes for this reaction chamber too, that heating can take place with coolant or oil from the lubrication system of an internal combustion engine, and that the reaction chamber can be completely or partly integrated in the engine block.
  • heating systems in which the heat generated by an internal combustion engine is employed, it is also possible to use other energy sources for at least part of the heating. This may play a part in starting an internal combustion engine, in which one can't yet use heat generated by the engine.
  • Possible energy sources are e.g. a heating spiral connected to the electric circuit, or a high frequency source of radiation such as a magnetron.
  • a heating system fed with the help of photovoltaic cells, or a system in which a liquid heating medium is directly brought to temperature by the sun.
  • the invention provides for injection systems for petrol and diesel engines, respectively, which will be further explained in the following, an important feature being that the fuel is reformed and is at least partly brought into the gaseous phase, contrary to the atomizing systems applied up to now, in which the fuel remains largely in liquid state, preceding the mixing of the fuel with an oxygen-carrying gas.

Said inlet 65 also connects tangentially to the tube portion 33 and in the direction of the vortex generated there, as a consequence of which a better blending with the mixture can be achieved.
  • the inlet can further be provided with an underpressure-dependent valve.
  • the effect of the air supplied in this way is particularly well noticeable with the higher speeds at which the engine can operate, e.g. with driving on the highway, in which the underpressure of the engine is the highest. In this way, more power and a more economic consumption is realized at the same initial amount of fuel/air mixture.
  • the inlet 65 is also suitable for e.g. supplying a certain amount of water or water vapour or hydrogen to the mixture .
  • the tube part 31 will be mounted on the outlet manifold, but preferably, the tube parts 31, 32 and also portions of the tube parts 30 and 33, are thermally coupled to the outlet manifold by a highly heat -conductive enclosure. Then, the actual reaction chamber will extend across a major part of the total length of the tube parts. With the most common construction materials, the tube parts will already have some catalytic effect on reformation of the larger hydrocarbon molecules. However, it is just as well possible to apply a specifically catalytic material in the inner surface of the tube walls.
  • Four guiding members 27, 28 to be brought into a tube part are shown in Figs. 5 A,B,C,D.
  • the guiding member 27 is helically wound and has, in relation to the tube part in which it should be mounted, a diameter such that the outer circumference will contact the inner side of the tube porti- on 30, in order to have a proper thermal contact with it.
  • the guiding surface 31 of the guiding member extends radially from the outer circumference 39 up to some distance from the centre line 42, so that a free continuous space remains around the centre line 42.
  • the guiding surface is curved in radial direction and in such a way that at the upstream side, arrow 43 indicates the direction of flow, the guiding surface is convex. Owing to this, the lighter hydrocarbon molecules arising during reformation, can get quicker into the central onderpressure part of the guide 37, 38 and into the tube 40 and from there continue directly to inlet manifold and combustion engine.
  • Fig. 5C shows a similar guiding body 38, its guiding surface, seen radially in cross-section, being straight with a slope towards the centre line 45 which always goes with the stream.
  • Fig. 5D shows a similar guiding body 67, its diameter tapering with those of the subsequent tube parts 65, 66.
  • the tube parts and the guiding body are intended for providing a volume enhancement for an expanding fuel or a fuel/air mixture as a consequence of its warming-up.
  • Fig. 6 shows a tube part 46 with a number of coaxial guiding members 47, 48, 49, 50, 51, together in turn providing a free central passage 52.
  • Such an embodiment has the advantage of a much larger surface and due to that a better heat transfer and catalytic action.
  • Fig. 7 shows an embodiment of the device having a tube part 25' coming from a carburettor or similar member, a reaction chamber comprising tube parts 53, 54 with respective guiding bodies 55, 56, and a further tube part 27' con- necting to tube portions 53, 54, through which the fuel/air mixture can be supplied to the combustion engine through said inlet manifold.
  • Tube parts 53, 54 are mounted in parallel, in which one of the tube parts can be closed-off with the help of valves 47, 48 mounted at one end or both ends.
  • the valves are designed or switched in such a way that in case of a greater demand and thereby a greater underpressure, the valves will open and the required fuel/air mixture can be led through both tube parts 53, 54. With a smaller demand, the pressure drop across both tube parts 53, 54 will not be sufficiently large to be able to generate the desired vortex, so that then one tube part can suffice.
  • valves are pressure-dependent mechanichal valve, which doesn't require any external operation.
  • a valve 58 has e.g. a valve seat 66 onto which flexible valve portions 67, 68, 69 have been fastened with fasteners 70, 71, 72.

  • the guiding body consists of two twisted threads 78, 79, which are inserted into the tube part 74 before the tube portion is bent into the desired shape.
  • Fig. 9 differs in relation to the previous embodiment in that an expansion chamber 80 has been provided, in order to be able to accomodate volume changes caused by heating of the fuel. Such a provision will not always be necessary, this depends on the temperatures achieved with the source of heat employed, among other things.
