Description

The invention relates to a feed distributor

  tion between two energy sources, from a combustion engine

  internally, the carburetor in which the liquid air fuel mixture is produced and the mixer in which the air gas mixture is produced being connected to the fuel mixture intake manifold by outlets

  comprising an accelerator throttle.

  As a result of the increasingly high costs of petroleum products, it has been envisaged to at least partially supply the engines of motor vehicles with

  more economical fuels such as alcohol, natural gas

  turel, propane, gasifier gas, etc. The function-

  an engine from a fuel such as

  cool, natural gas and propane for which there is a reserve (tank or bottle under pressure) usable directly by simple switching on, does not pose any

major problems.

  It is not the same for gasifier gas

  which is produced in a generator mounted on the vehicle.

  Indeed the ignition of the generator is not immediate and it takes a certain time before it produces a sufficient quantity of gas to ensure the supply of the engine under normal conditions In addition the flow

  gas can only be controlled by the functions.

  generator and therefore, if the conditions of use of the vehicle are constant, i.e.

  if the power required from the engine varies little, the production

  tion of gas can be easily adjusted on demand It

  the same is not true for rapid variations in function.

  such as start-up, crossing of elevation

  lation, where the gas flow required by the engine cannot-

  very quickly from maximum to minimum or vice versa

  sa The problem posed by an abrupt reduction in the de-

  gas request received an acceptable solution which allows

  maintain the generator at a sufficient production level

  health to avoid its extinction On the other hand the abrupt de-

  demand for greater gas flow when starting or crossing a c 8 te did not find a solution

2531142.

  satisfactory by the sole use of gasifier gas.

  The solution adopted therefore consisted in using a

  fuel that can be stored For reasons of simplicity

  cited and given that the currently existing engines run on either gasoline or diesel, we kept the supply of one or the other of these fuels to provide the additional power required during

  special operating conditions.

  The intake manifold for the fuel mixture engine comprises on one side the carburetor in which the air-petroleum product mixture is produced and on the other

  the mixer in which the air-gas mixture is made

  zogen A butterfly or a valve, placed between the two,

  allows to control the admission of each of the mixtures.

  Known devices are generally quite complex and use ball valves or multiple butterflies whose handling is ensured by a large linkage requiring for its control a

  minimum of two independent drawbars.

  The invention proposes to simplify the arrangements

  existing sitives and has for its object a food distributor

  tation from two different sources of energy

  annuity requiring only one control device to vary in any proportion the

  quantities of mixtures admitted into the engine cylinders.

  The distributor according to the invention is remarkable

  ble in that it includes papillus connecting means

  lons of accelerator to a control lever capable of being actuated by a control means, said means

  of connection being at least partly mobile along the

vier command.

  The explanations and figures given below to

  example will help understand how the invention

tion can be carried out *

  The power distributor of a

  internal combustion from two energy sources,

  lon the invention aims to allow the use of two fuels with different calorific values and in particular a liquid fuel with high

  calorific value and a gaseous fuel capable of

  lorifique plus basseo According to an example embodiment

  below describes the fuel with high calorific value is petrol or diesel and the fuel with lower power of gasifier gas obtained from a generator

mounted on the vehicle.

  Carburetor 1 and mixer 2 (Figure 1)

  are connected to the motor by a single supply pipe

  tion 35 As generally accepted, liquid fuel (petrol or diesel) is sent to the carburetor o

  the mixture feeding the cylinders and the fuel takes place

  rant gas (gasifier gas) in the mixer

  carburetor and mixer links are provided two papile

  lons 4 and 5 normally connected to the acceleration control

  tion Throttle valve 4 is called the carburetor throttle valve and throttle valve 59 is the

  mixers By separate operation of each of these butterflies

  -lons it is possible to switch from the supply from the gasifier gas to a supply with a fuel

  liquid (petrol or diesel) o The distributor, according to

  vention, comprises means for connecting the butterflies 4 and to a control lever 6 capable of being actuated by a control means 79 said connection means being at least partially movable along the control lever The butterfly 4 of the carburetor 1 and the butterfly 5

  of the mixer 2 are respectively connected in an articulated manner

  abutment, by connecting rods 8 and 9 to the lever 60 An arm 10, shown perpendicular to the center of the lever 6, makes it possible to rotate the lever around a

  central axis 11 mounted on a fixed support 12.

  According to the embodiment shown in Figure 2531142 j 1 and 2, the ends of the rods 8 and 9 cooperating

  with the lever 6 are held by a connecting rod

  pitch 13 sliding in a longitudinal groove 14 of the lever 6 The length of this link is chosen so that the connecting rods 8 and 9 are substantially parallel The connecting rods 8 and 9 are articulated to the spacing rod 15 by

ball joints 15, 16.

  The end of the connecting rods cooperating with the butterflies 4 and 5 are articulated at the end

  a lever 17, 18 fixed on the axis of the butterflies of ma-

  denies that during the simultaneous maneuver in the same

  direction of the opposite ends of the two connecting rods

  sound 8, 9, the butterflies rotate in reverse

itself, as shown by the arrows.

  The displacement of the spacer link 13,

  and therefore the ends of the connecting rods

  its 8, 9 which are connected to it by the ball joints 15, 16, is obtained by a linear movement control system 19 provided at one end 20 of the lever 6, the system being

  actuated for example by a pull tab 21 fixed on the ta-

  edge board Such a system is constituted, for example, by a sheath, maintained by the fixed parts, and

  in particular by the end of the lever 6 and the body

  xe of the zipper in which a flexible cable slides fixed by its ends on the one hand to the end of the

  spacer rod 15 and on the other hand to the pull tab

control bile.

  In the example shown, the position of the ro-

  tule 15 of the connecting rod 8, cooperating with the pa-

  fuel rod 4 was chosen coaxial with the axis

  pivot 1 l of lever 6 Under these conditions, the

  vote of lever 6 under the action of the accelerator pedal

  ration 7 will have no action on the rod 8 and therefore on the throttle valve 4 of the carburetor and the engine will be powered only by the gas from the mixer 20 Conversely, when the movable pull tab 21 is

  placed in the position shown in dotted lines, the biellet-

  your 8 and 9 will come in the 8 A and 9 A positions shown

  in dotted line The ball joint 16 to which the connecting rod is connected

  lette 9 cooperating with the butterfly 5 of the mixer is then placed on the axis of rotation of the lever 60 When the latter pivots 9 the rod 9 remains stationary while the

  rod 8 actuates the throttle valve 4 of the carburetor for ad-

  put in the engine the mixture for example air-gasoline All the intermediate positions between 89 8 A and 9, 9 A will correspond to proportional displacements of the butterflies 8.99 these proportions varying in opposite direction according to an infinity of combinations from O to 100% o

  To obtain a perfectly parallel displacement

  lèle of the rods 8 and 9 it is absolutely necessary that the lever 6 or at least the groove in which the rod

  spacer 13 or slides held by the biel-

  sliding slide 13; presents two successive curves of

  radii corresponding to the lengths of the connecting rods

  sound 8 and 9 e The distributor, 9 according to the invention 9 therefore makes it possible to start with a fuel with high calorific power liquid or gaseous stored 9 while the gasifier is gathering

  then switch to the gasifier gas and finally to intro-

  deduct a greater or lesser percentage of fuel with high calorific value to provide additional power when crossing a steep, or a course

in the city.

  It goes without saying that one or the other of the devices

  1 and 2 respectively designated as Icar-

  desktop "and mixer" can be replaced by a pump

  injection of liquid fuel or a pressure regulator

  gas bustible without departing from the scope of this invention
