Definitions

  • This invention relates to an apparatus of carburetion which allows the integral and complete carburetion of air by means of light or heavy hydrocarbons designed for feeding explosion or combustion motors.
  • Said apparatus is based upon the principle of contact and characterized by the great number of contact surfaces used, as we ll as by the progressivity of the extent of the surfaces brought in action according to the required volume of gaseous mixture and the power to be supplied.
  • the apparatus is characterized by the utilization of wicks or similar devices of pervious material contained in special wick-carriers dipping in the hydrocarbon used as fuel and provided with inlet orifices suitably arranged so as to present upon the interior wicks, the greatest possible contact surface to the air.
  • the apparatus for the execution of the present system comprises a large number of wickcarriers arranged for example in double, threefold or multiple series which may be actuated successively in order to proportionate the Volume of gaseous mixture which is produced relatively to the motive power to be supplied by means of a suitable distributor which is preferably combined with the motor inlet Valve.
  • Said apparatus may be mounted upon the carburetant receiver or upon an independent receiver or supply device, the gaseous mixture which is produced passing directly from said receiver to the motor inlet pipe. It thus takes the place ⁇ of the usual Carburettor as Well as of the feeding pump.
  • the gaseous mixture produced by the above mentioned carburetion method is homogeneous and stable at all working temperatures, it does not produce any deposit or condensation in the pipes, it is well carburetted, even on starting and thus allows an instantaneous starting without requiring the use of supplementary apparatus such as starters and enrichment devices.
  • the present system may be utilized with both light and heavy hydrocarbons.
  • FIGs. 1 to 5 illustrate a form of the device in which numerous and successive Contact surfaces are provided for enriching the gaseous mixture which has been produced.
  • Fig. l is a vertical sectional View of the device on line 5 5, Fig, 2 which is a plan View of same, the upper air and gaseous mixture tubes and the rotary distributor not being shown.
  • Fig. 3 is a sectional detail view on line 1 1, Fig. 2.
  • Fig. 4 is a plan view of the rotary distributor.
  • Fig. 5 is a diagrammatic View similar to that of Fig. 3 of a modified mode of execution.
  • the improved apparatus shown in Figs. 1 to 5 is composed of a ring shaped casing I which 5 is positioned upon an opening suitably formed in the upper wall of the fuel receiver 2.
  • Said casing is divided around its periphery in a certain number of series of ring shaped cells 3, 4, 5, three in the present case in which the wick carriers are contained.
  • the latter are constituted by an upper tubular part B-a which is provided at the bottom with a tubular extension 'l of smaller diameter which contains the wick B and dips with the latter in the liquid contained in the receiver 2.
  • the upper portions S-Ba of the wick carriers in which the wicks 8 rise have a diameter which is calculated so that the air or the gaseous mixture may circulate in the form of a thin sheet around said Wicks.
  • the casing l is closed by a covering plate 9 presenting numerous orifices Il) (sixteen in the present case) to correspond with the outlet cells for the gaseous mixture.
  • the upper tubular enlarged parts Ga of the wick carriers occupy the entire depth in said outlet cells and in the other cells the upper tubes 6 of the wick carriers end at a short distance from the plate 9.
  • Every series of cells is distributed in a certain number of groups as shown, for example eight groups n in the series of cells designated by 3, four groups in that designated by 4 and four groups in the series of cells designated by 5.
  • Each group of cells comprises an outlet cell S and an inlet cell E, the latter being provided at the bottom withv a circular air inlet opening 3a, 4a, 5a around the lower tubular wick carrier 1.
  • the cells 3, 4 and 5 in the different groups are provided at their opposite lower and upper corners with connecting slots Il; on the other hand the upper tubes 6, 6a of the wick ⁇ carriers are provided at the bottom with air passages l2 in such a manner that the air admitted in the inlet cell E in each group may thus be laden with hydrocarbon atomized by its passage around the upper portion of the wick in said cell, so that the gaseous mixture thus produced may be kprogressively enriched by its passing successively along the wicks of the intermediary cells, and lastly so that the correct gaseous mixture may now out from the outlet cell S through the oriiice lli in the stationary upper covering plate 9,
  • the successive contacts of the wicks with ⁇ the thin annular sheet of gaseous mixture produce the thorough atomization of the hydrocarbon and consequently a perfectly homogeneous gas.
  • the Wick carriers may also be inclined at their upper part in the direction of the forward movement of the gaseous mixture, as shown in Fig. 1, so as to avoid as much as possible loss of charge and sudden bends in the passage of the gaseous mixture from the inlet cell to the outlet cell in each group.
  • the Wick carriers may also be inclined as a whole and not be provided with an enlarged upper tubular element, the top of the wick thus being left free so that the carbureting air as it proceeds may come successively in contact with the top of the wicks which are impregnated with hydrocarbon thus getting progressively enriched.
  • a plan revolving distributor I3 provided with three series of openings
  • an upper covering body comprising a gaseous mixture tube
  • a throttle valve I1 is mounted at the outlet of the gaseous mixture tube i4; it is driven by a system of rods I8 connected with the accelerator.
  • a rod and lever system I9 connects the driving means of the gas throttle valve with a vertical shaft 2li to which the revolving plane distributor I3 is suitably fixed.
  • is mounted in the air inlet tube I5, the shaft 22 of said valve is pivoted off-center in order to ensure its automatic closure when there is no depression and its automatic opening to the desired degree by the action of depression produced by the working of the motor.
  • the motor being started by the opening of the throttle valve l'l, said opening causes the rotation of the distributor I3 whose openings I3b come opposite the orifice I0 of the outlet cells S in the intermediate cell series 4 which in the arrangement shown by way of example are the cells for the reduced speed.
  • the strong depression acting upon the wick carriers inside the cells of this series causes the air admitted at lZL to flow upon the wicks of the five successive cells in said group, thus ensuring a perfect enrichment of the mixture and allowing the direct starting of the motor with a gaseous mixture that has been enriched to the highest possible extent.
  • a secondary branch (not shown) formed upon the gas nozzle I4 may be preferably provided for the passage of the gases when the motor works at reduced speed, the gas throttle valve being then closed.
  • the distributing orifices I3c then uncover the orifices of the outlet cells in the inside series 5, the cells of the intermediate series 4 which have been previously uncovered and those of the outer series 3 remain also uncovered owing to the elongated shape of the distributing orifices I3b and
  • the gaseous mixture is then produced by the whole of the intermediate cells 4 workin-g with five successive enrichments, the whole of the inner cells 5 and half the groups of the outer cells working with three successive enrichments. Normal working at full speed is thus obtained.
  • the wicks may be replaced by any other porous device having capillary properties which make it liable to act in the same manner.
  • the special arrangement of the carriers for the wicks or other capillary elements may be varied at will whilst ensuring the same effect from the contacting surfaces.
  • the distributor instead of being rotary (Figs. 5 to 9) or revolving (Figs. 5 to 9) as shown could be of any other kind, it may consist for example of a set of vertically movable valves either independent or combined which may be actuated by means of a driven plate which causes said valves to operate successively so as to cause them to open and close in a predetermined order suited to the distributing conditions.
  • a carbureting apparatus for combustion motors which comprises a plurality of cells, Wicks of pervious material, Wick carriers containing said Wicks and placed in said cells which are distributed in series, each series being divided into independent groups, the first cell in each group forming an inlet cell and comprising an air inlet, the last cell forming the outlet cell, all the cells in each group communicating together; a liquid fuel receiver in which the Wick carriers dip with their Wicks, said receiver comprising an upper coinpartment formed therein for the air admitted to the Wick carrier of the outlet cell in each group, a distributor, and means driving said distributor to successively and progressively uncover the various groups of cells.
