Definitions

  • the invention relates to a molecular diffraction device operating in the inlet gas stream downstream of the carburetor or of the injection system of internal combustion engines, comprising a support frame for the diffraction structure, itself blocked therein. by a fixing system.
  • the air fuel mixture is made in the carburetor or in the intake manifold downstream of the injector before passing into
  • the combustion chamber The optimum value of the mixture is around 14.6 grams of air for one gram of gasoline, the ratio required for complete combustion; or stoichiometric ratio. For this stoichiometric ratio the coefficient is equal to 1.
  • the passage devices inside the structures being made up of smooth circular or rectangular conduits and, because of these configurations, cause a phenomenon of condensation on the internal wall of the conduit, condensation linked to the speed variation. gases.
  • venturis systems use venturis systems. These venturis are arranged in more or less large numbers, either side by side, or in superimposed stages, system based on accelerations and decelerations of the gas column, American patent no 2721-791; type of structure in contradiction with the Tanasawa and Nukiyama equations, this system causing pressure losses and condensation.
  • the present invention implements a new fuel spraying technique inducing the molecular diffraction mechanism.
  • the invention as characterized in the claims makes it possible to completely eliminate the phenomenon of condensation on the internal walls of the transfer channels of the structure, condensation which is the pitfall of all the systems prior to our knowledge.
  • the invention consists of a device with one or more elements or stages intended to implement the molecular diffraction mechanism.
  • the device according to the invention consists at least of a conical structure upstream of the gas column in the direction of flow of the gases.
  • the entrance to the transfer channels has walls whose slope is defined by a precise angle. These walls receive the shock of the gaseous molecules which reflect their trajectories and favor the shock of the particles between them.
  • the profiling of the inlet of the duct also acts by accelerating the gas column.
  • the abrupt increase in section of the transfer channel over a very short distance is intended to avoid, by creating a separation of the gas stream, the maximum friction of the gas molecules against the wall, This configuration avoids a sudden variation of the speed of the gas stream before meeting the diffraction slots of the base of the structure
  • the angle of attack ⁇ 39 of the diffraction slits is determined by the ratio of the width of the slit to the diameter of the radial well perpendicular to the transfer channel.
  • the slit which is a rectangular orifice is an essential element in the molecular diffraction mechanism.
  • the kinetic energy of the deviated molecules dissociate the molecular structures into smaller structures, which have an overall surface larger than the initial surface.
  • the engine requires the same amount of energy; as the heat energy of the fuels is increased, less fuel will be required for the same engine job.
  • the present invention can be adapted to all motorized vehicles (air, sea, land) in order to bring a marked reduction in consumption as well as a marked reduction in polluting substances (carbon monoxide, mono nitrogen oxide and unburnt ) as confirmed by mass spectrometry and chemiluminescence analyzes.
  • the figures represent the gas molecule diffractor according to the invention intended for internal combustion engines (not shown) or the like. It comprises an external frame 10 having a central and longitudinal channel 11.
  • the frame 10 which can be made in any suitable manner with the most suitable material. It comprises a cylindrical part 12 which has an open end 13 and a second end comprising lugs 14 and 14a, intended for fixing on the one hand to the intake manifold and on the other hand to the carburetor at the top by through the ears 15 and 15 a.
  • the ears have holes 16 - 16a, 17 - 17a, which allow the junction with the carburetor or the injection system tion on the one hand and the intake manifold or cylinder head on the other hand.
  • the internal peripheral surface of the frame 10 has at its lower part a circular part 18-18a, having a venturi structure, that is to say a part converging towards the inside of the frame, on the upper face side, and a diverging part on the face side lower.
  • This part is intended in addition to its dynamic function to block the position of the structure of the diffractor 19.
  • the structure of the diffractor 19 according to the invention represented by FIGS. 1-2-3, has at its upper part elements 20 of triangular shapes with vertices converging towards the center of the diffractor, each triangle present at its base and according to the radius of the circle of the diffractor, a groove 21, or transfer channel, which passes right through by dividing the base into two small triangles 22 - 22 a, having in turn a small groove 23 at their base.
  • the grooves could possibly be replaced by close cylindrical holes or ovoid bores or of any shape whatsoever.
  • the structure of the diffractor can be imagined integral with the frame by the base of the triangular elements and the top of the triangles of which would then no longer be integral.
  • the surface of the diffractor has a roof top.
  • the surface of the diffractor has grooves, or transfer channels, on its top 25 along the radius of the diffractor and in the axis of each transverse groove 21, an axis passing through the middle of the base of each triangle 20.
  • the lateral structure of the "diffractor according to the invention represented by FIGS. 1-3-4 presents wells 26 of suitable shapes, one or more superimposed whose axis corresponds to the radius of the diffraction structure and perpendicular or oblique with respect to to the direction of flow of the gas stream.
  • the structure of the resonance chamber 27 according to the drawback shown in FIGS. 1 and 4 is characterized by an empty space containing in its center a junction pin 28 spacer which advantageously makes it possible to create a zone of turbulence.
  • the structure of the second diffraction stage 29 according to the invention tion represented by Figures 1-2-4- presents elements of triangular shape 31 whose upper part can be striated or not had the same title as the surface of the first diffraction stage.
  • the grooves can be replaced by conduits of variable shapes whose axis is that of the axis of the entire diffraction structure but can also be different from this axis.
  • the grooves 32 are parallel to the axis of the assembly or can be oblique and along the radius of the body of the structure.
  • the lateral part of the second diffraction stage has cylindrical wells 26 whose axis corresponds to the radius of the structure
  • the structure of the third diffraction stage according to the invention represented by FIGS. 1 and 4 has a cylindrical assembly integral with the frame 10, an assembly consisting of a conver gent 34 reducing the channel and a digergent 35 restoring the diameter identical to the one before the strangulation.
  • cylindrical channels 36 In the convex part 18 of the structure I strangulation of the ven turi, are located cylindrical channels 36 whose axis is either parallel to the body of the frame, or slightly oblique, but which make the converging part communicate with the diverging part.
  • the flow of the gas mixture coming from the carburetor supply system 37 or injection system passes through the first diffraction stage, to reach the resonance chamber, passes through the second diffraction stage to be accelerated by the 'stage of the venturi before entering the intake manifold 38.
