  • the adjustment of the carburetor may be changed by increasing preferably the diameter of the venturi and by adapting the diameters of the main fuel jet and of the air mixing jet so that, taking into account the action of the other means employed, there is normally an excess of air of to and especially in the case of starting-up from cold, with no load, during deceleration, when picking-up and on full load, or again an excess of air or an excess of fuel which is as small as possible.
  • variable throttle means for the flow of carburetted gases passing out of the carburetor overlaps, butterfly, cock
  • variable throttle means for the flow of carburetted gases passing out of the carburetor overlaps, butterfly, cock
  • wiredraw the carburetted stream mainly at low rates of fiow and at low pressure drops that is to say under the conditions for which the carburetor itself provides a poor atomization and a mixture which is particularly heterogenous
  • a device responsive to the pressure drop existing in the admission pipe is caused to act in the direction of opening, either directly or preferably through the intermediary of a servo-motor (for example by pressure drop) on the butterfly-valves of the carburetor or, on the stop which fixes the minimum opening of this butterfly-valve.”
  • a servo-motor for example by pressure drop
  • 1 1 -(h) In order to obtain the most reliable and most uniform ignition which may be compatible with the proportions produced by the other elements of the invention, there may be provided according to the invention, a second cam rigidly fixed to "the same support as the cam which is actuated in two different directions by the butterfly-valve of the carburetor and 'by the pressure'drop in order to regulate the additional air and to cause this second cam to act on a second feeler so as'to adjust the advance of the ignition-or to perfect the adjustment obtained by conventional means, depending on the particular object envisaged by the invention;
  • FIG. 1 is a diagrammatic view of the arrangements of a carburetor equipped forthe application of the invention.
  • FIG. 2 is a diagram explaining the method of heating
  • FIG. 3 illustrates the method of extraction of the additional air from the crankcase.
  • FlGy4 is concerned with the mechanism the butterfly-valve of the carburetor
  • FIG. 5 is a perspective view of the Whole of the device which, in association with the carburetor, ensures the regulation of the fuel supply mixture to theengine. r a
  • FIG. 1 the carburetor is shown by its main elements:
  • the calibrated orifices of the carburetor, main orifices and slow-running orifices are determined so as to reduce the excess of fuel to a value less than 5%, or to eliminate theexcess altogether.
  • the carburetor represents by its choke-tube 1 and its butterfly-valve 2
  • the admission pipe 3 leading the carburetted mixture to the engine is mounted the annular member 4comprising holes 5 for the introduction of additional air.
  • the annular member 4 is coupled to an air-admission conduit 6 communicating by pipe '7 with the air filter of the engine.
  • the air admission pipe '7 comprises a regulating device constituted by a sliding valve 50 with an orifice 51.
  • This slide-valve is actuated by a bell-crank lever 52 pivoted at 53 and actuated by a feeler 54, the extremity of which is preferably spherical and is. applied elastically against a cam 55.
  • the cam 55 is carried by a segment 56 pivoting about a shaft 57.
  • the shaft 57 is mounted on a slide 53 arranged to move vertically.
  • the additional air thus -adm itted tothe orifices 5 in quantities determined according to the conditions of operation of the engine is preferably pre-heated so as to facilitate evaporation of the residues ofliquid petrol and also in order to compensate for the influence of external conditions, in particular the ambient temperature.
  • This pre-heating which can with advantage attain an average temperature of 150 C. is effected by the engine exhaust.
  • the admission pipe 7 for thejadditional air is coupled-by a pipe-63 to a sleeve 64,0per1 at least at one extremity, mounted around the hot portion of the exhaust pipe '65.
  • the temperatureof the air admitted at.7 is regulatedby themixture of "the air heated in the sleeve 64, drawn-in at 63, with the exterior air admitted at 66, by means of a regulating flap 67 pivoted at 68.
  • Theregulatores may becontrolled by a thermostat in accordance with the exterior temperature.
  • the additional air admitted to the orifices 5 bythe pipe 7, and the flow of which is regulated by the slide-valve 50, can be extracted wholly or in part from the crankcase 70 (FIG. 3) with the object of reducing the upward pasfor avoiding'advcrse effects. on the lubrication of the pistons of the engine.
  • This device consists of a box 72 interposed between the conduits 71 and 7, and comprising a valve 73 which puts the box 72 in'communication with atmospheric air when theadrriission pressure becomes less than a pre-determined value.
  • valve'73 is controlled by the pressure drop downstream of the carburetor.
  • the rod 74 of the valve 73. is actuated by a lever 75 pivoted at 76, and the extremity 77 of which is actuated by the sheath 78 of-ra flexible cable-79fixed onthe one hand to a fixed point 80 and on the other to' the extremity 27 of the lever 26 actuated by the'bellows 17.
  • valve 73- is automatically balanced by the force which is trans! mitted to it by the lever 75, aslong as the pressure drop does not excecd a predetermined fraction of the pressure drop existing in the admission pipe downstream of the carburetor, for example two-thirds, and the valve 73 re- 'mains closed as 'long as this fraction is not reached.
  • a clapper-valve 81 playing the part of a blow-valve, permitting the crankcase to communicate with the atmosphere or with the intake of the air filter, but preventing the return of atmospheric air into the crankcase.
