Definitions

  • SHEET 2 OF 2 CARBURETOR BACKGROUND OF THE INVENTION The general idea of this invention is to supply a combustible mixture to internal combustion engines, particularly automobile engines, which should, from now on, comply with the strict standards of the anti-pollution laws.
  • Fuel supply to internal combusition engines is normally carried out by one or more carburetors or by a direct or indirect injection device whose purpose is to mix fuel with the intake air in proper proportion for operations of the engine.
  • An ideal mixture for all engines can be realized only by employing complex mechanisms which, as a consequence, are costly, require delicate adjustment and are prone to go out of adjustment with normal usage.
  • the fuel mixture is rarely optimum for the operation of the engine, thus the exhaust gasses contain pollutants, which are not insignificant and therefore important, such as oxides of carbon, various oxides of nitrogen, unburned hydrocarbon, also tetraethyl of lead and other additives which are incorporated in the fuel but do not burn.
  • pollutants which are not insignificant and therefore important, such as oxides of carbon, various oxides of nitrogen, unburned hydrocarbon, also tetraethyl of lead and other additives which are incorporated in the fuel but do not burn.
  • pollutants which are not insignificant and therefore important, such as oxides of carbon, various oxides of nitrogen, unburned hydrocarbon, also tetraethyl of lead and other additives which are incorporated in the fuel but do not burn.
  • the object of this invention is a method and application for supplying (fuel) to an internal combustion engine which is not only easily and inexpensively accomplished, but in addition meets the various existing or future regulations as numerous official tests have proven.
  • This invention provides the following fundamental functions: Furnish the engine, while cruising or accelerating, with a dry, automatically, proportioned combustible mixture by centrifugal action as a result of its speed, with recovery and eventual recycling of excess fuel and elimination of entrapped impurities.
  • With the engine throttled down furnish the engine with only a separately prepared combustible gas mixture brought about by mixing the fuel in fixed proportions in a small flow of primary air, then heating of the mixture, for example, by the exhaust gasses, and finally admission of a prescribed flow of secondary air.
  • the intake is connected to the exhaust.
  • this invention includes fundamentally and in combination: A principal device, to supply the engine while cruising and accelerating which is located downstream of the conventional means (carburetor) of atomizing fuel in the intake air stream and which will have static elements to dry the mixture by centrifugal action resulting from its rapid outflow, and also succeeding means of collecting and eventually recycling excess fuel and eliminating entrapped impurities.
  • An auxiliary device whose purpose is to supply the engine, when throttled back, which has, besides the conventional means for mixing fuel in prescribed proportions with a small flow of primary air, means for heating the mixture, for example by exhaust gasses, and means for adding to the mixture, thus heated a metered flow of fresh secondary air.
  • a control device consisting first of an accelerating butterfly (valve) capable of tightly shutting off flow between the principal device and the intake to the engine, and, secondly, an automatic three-way valve by which a discharge path downstream of the aforementioned butterfly is selectively connected to the auxiliary device, or if the butterfly is closed because the engine speed is greater than a selected limit, with the engine exhaust.
  • a accelerating butterfly valve
  • an automatic three-way valve by which a discharge path downstream of the aforementioned butterfly is selectively connected to the auxiliary device, or if the butterfly is closed because the engine speed is greater than a selected limit, with the engine exhaust.
  • the principal device consists essentially of a tubular container provided with an inlet connection located over an outlet connection, arranged coaxially and essentially of the same diameter, in which the following elements are located in the mainstream of the mixture flow:
  • a system of elastically flexible blade which imparts a helical flow to the aforementioned mixture where the pitch of said helical flow varies as a function of the velocity of the mixture.
  • the invention will supply the engine, under all operating conditions, a combustible mixture wherein the proportion of fuel will be optimum, because whether cruising or accelerating, the mixture is automatically proportioned by the same factor, its velocity, which reflects exactly the requirements of the engine, while when idling the engine receives a perfectly dry mixture proportioned once and for all (the inference here is that the proportioning is in fixed ratio). Otherwise, during periods of deceleration, which generally result in the consumption of unburned fuel, when, in turn, increases the emission of pollutants, the supply to the engine is completely cut off without affecting the necessary braking action which is assured by the partial recycling of the exhaust gasses.
  • the invention not only reduces considerably the emission of the pollutants under all operating requirements of the engine, but again appreciably reduces fuel consumption.
  • FIG. 1 is a schematic top view of an internal combustion engine equipped with anti-pollution device such as this invention
  • FIGS. 2, 3 and 4 show respectively, a cross section parallel to the main axis, a cross section'perpendicular to the axis, and an exterior right hand side view of FIG. 1, and
  • FIG. 5 shows an electrical schematic drawing of the control circuit.
  • FIG. 1 is a top view of a schematic representation of an internal combustion engine, 1, where the intake manifold and the exhaust manifold are respectively shown as 2, and 3.
  • This invention is shown, in essence, as item 10, mounted directly on the intake flange of the .intake manifold 2, provided with an acceleration control 5, and connected in one place to the exhaust manifold 3 by a reclaiming tube 6, and in another place by a speed sensitive contact.
  • (electrical) 7 mounted on the end of the generator or alternator shaft 8 by wire 9, with other electric connections with ground (electrical) and positive polarity indicated by appropriate symbols.
  • Item 10 is shown in detail by the cross sections and side views of FIGS. 2, 3 and 4.
  • This item has the overall shape of a short flanged chamber placed between the conventional simplified carburetor 11 and the intake-flange 12 of the intake manifold.
  • This chamber is made up of a cylindrical wall 21 closed atone end by the bottom 22 and attached to flange 12 with a gasket in between and closed at the other end by a removable cover 23, with gasket, fastened to the flange 24 which forms the end of wall 21.
  • the body 13 of carburetor 11 is fastened to cover 23 by dowels 14.
  • the carburetor venturi 15, furnished with the usual atomizing nozzle 16 discharges into an inlet port 25 located coaxially and passing through cover 23.
  • the bottom 22 of the chamber 20 forms into an inner annular wall 26 making an outlet port 27, located coaxially with the inlet port 25 and of essentially same diameter.
  • a butterfly (valve) shaft 28, to which is attached a butterfly valve 29, is located diametrically across the outlet port 27, and is rotated by an accelerator control 5 and is capable of completely closing off the aforementioned port 27.
  • Essential parts of the principal element ofthis supply device are located inside the chamber 20 and serve to correct the proportioning and clean the combustible mixture coming from the carburetor when the engine is cruising or accelerating.
  • This device is made up essentially of static elements 30, made up in one part, ofa system of elastically flexible blades 31 mounted in the inlet passage 25 integral with a conical skirt 32, and in another part, of an annular trough 33 mounted on a rabbet 26 at the inner end of the outlet passage located under the free end of skirt 32, these various elements being made adantageously of plastic materials.
  • the blade system 31 is made up of four radial blades with their leading surfaces fixed in the axial direction and intergral with the upper end of skirt 32 and a central hub, and with their trailing surfaces curved to a particular shape.
  • the individual blades 31 of the system are curved identically and in a manner so as to impart a helical flow to the combustible mixture passing through the inlet 25.
  • the free curved ends of the blade system 31 are elastically flexible and tend to diminish their effectiveness (by changing shape) as the velocity of the combustible mixture increases. It follows that the mixture is subjected to a centrifugal action wherein the force (centrifugal) decreases with speed in accordance with the influence of the blades determined by their shape and flexibility, which, at the highest speed, are practicallystraightened out. For example, used like a flag in a high wind" and to have practically no effect on the flow of the mixture.
  • the denser particles in the combustible mixture such as dust, and other suspended impurities, and globules of unvaporized fuel are thrown against the skirt 32 and drip down the wall of the skirt eventually falling into the gutter 33 which serves as a collector.
  • the rim of the gutter is gradually sloped and the heavy particles which have been collected fall into the annular depression 34 formed by the end 22 of the chamber 21 which serves as a temporary storage area. in effect, the annular space surrounding the skirt 32 forms a low pressure, slow-down chamber, which prevents the induction into the engine of the heavy particles in the combustible mixture which have been collected in the reservoir 34.
  • the reservoir 34 can be directly connected to an orifice 17 located in the throat of the venturi 15 by means of a siphon tube 36, which brings about an almost instantaneous recycling of the collected fuel. In this way the same torque can be obtained with less pressure on the accelerator, which results in fuel economy without sacrifice in performance. Recycling of the collected fuel can just as well be deferred, in which case the reservoir 34 is connected by a siphon tube 37 which terminates at the bottom of a closed receptacle 38 in which the upper space is connected to the orifice of 37 by an intake tube 39 which is capped with a filter or strainer.
  • the fuel collected in the receptacle 38 can be reused directly by the carburetor 11 as soon as its level reaches the inlet of the intake tube 39. Preferably, this fuel is always returned to the reservoir after being filtered which prevents faulting of the carburetor.
  • the accelerator pedal completely released, closes the discharge port 27 by means of the butterfly valve 29 so that the principal supply device is inoperative. In this condition, and in conjunction with another essential part of the invention, the combustible mixture supplied to the engine is processed by an auxiliary supply device 40 described in the following.
  • This auxiliary device consists of a chamber 41 in a horizontal protuberance 42 emerging from the wall of chamber 20, normally connected by a passage 43 leading from an orifice 44 located in the discharge port 27 downstream of the closed butterfly 29.
  • chamber 41 is connected on the one hand to atmosphere through secondary air nozzel 45 and on the other hand by a port 46 located in the horizontal protuberance 42 with the port partially closed off by a regulating screw 47.
  • the outlet end of port 46 is connected by tubing 48 to an inlet connection 18 which leads to the regular low speed nozzle in carburetor 11.
  • the length of this tubing 48 is heated, either by coiling it several times around tube 6, which is connected to the exhaust manifold, or by an electric heating element represented symbolically by resistance 49'.
  • the auxiliary supply device functions as follows.
  • the low speed nozzle in carburetor 11, is designed to handle a very rich mixture. Thismixture is first heated by coil 49 or resistance 49' to a temperature high enough to completely vaporize the fuel.
  • the regulating screw 47 allows adjustment of the small flow of hot gaseous mixture, thus obtained, to which a supply of relatively important fresh secondary air is added by means of the nozzle 45 to provide a low speed intake mixture which is supplied to the engine through chamber 41, passage 43, and orifice 44 located under the closed butterfly 29.
  • the engine receives a combustible mixture free from all liquid particles and will turn over smoothly and without emitting pollutants. Risk of condensed fuel in the intake is practically eliminated.
  • auxiliary device 40 When the engine is running at cruising speed or accelerating, the idling mixture furnished by auxiliary device 40 is not cut off but merely reduced because of the relative decrease in vacuum in the intake manifold 2. This is never a problem because the auxiliary supply device furnishes a limited supply of 5 combustible mixture which is purely gaseous.
  • the supply of idling mixture is completely cut off during periods of abrupt deceleration, that is, when the butterfly 29 is closed and the engine is turning up at considerably faster than idle speed. This cut off of the combustible mixture to the engine during deceleration, very helpful in reducing the emission of pollutant, is brought about by an electromagnetic control device 50 which is described in the following.
  • This device 50 consists essentially of an electromagnet 51 mounted at one end of protuberance 42 on the wall of chamber and where the armature 52 held in one position by a return spring 53 is connected by a shaft 54 to a sliding valve 55 in a bore or cylinder 56 which is built in between chamber 41 and the tip of the exhaust gas return tube 6.
  • This bore 56 forms a valve chamber with a central port which is the end of passage 43 which terminates at the other end in orifice 44 and where the opposite ends of the valve chamberconnect to chamber 41 and tube 6 by means of cut-off seats 57 and 58, the latter formed by milling the end of tube 6.
  • the electromagnet 51 can be energized by a control circuit 60 consisting of two open contacts 61 and 62 respectively actuatcd by the speed sensitive switch 7 and the accelerator control arm 5. These contacts are in the series with relay coil 63 and form a circuit from the positive battery terminal to ground. Contact 64 is closed by energization of coil 63 and applies battery voltage to the electromagnet 51 from positive battery through 51 to ground.
  • Accelerator control arm 5 closes contact 62 when the butterfly 29 of the principal supply device 20 is closed.
  • device 50 is a 3 way electric valve by which the intake manifold 2 is selectively cut off from the auxiliary supply device 40 and connected to the exhaust gas sampling tube 6 when the engine is turning over fast enough and when the butterfly of the principal feed device is closed.
  • three way valve could be controlled with electronic logic using other centrifugal sensors for speed signals possibly pneumatic or hydraulic.
  • the combustimble mixtures could be handled by means other than a carburetor.
  • the gathering up of exhaust gases could be done at the collector.
  • Apparatus for supplying a combustion mixture to an internal combustion engine, particularly an automobile engine, subject to anti-pollution regulations comprising:
  • a. a principal device designed to supply the engine, while cruising and accelerating, which has located downstream of the conventional means of atomizing fuel in the intake air to the motor, static elements to dry the intake mixture by centrifugal action due to the velocity of flow, and subsequent means to collect and eventually recycle excess fuel and eliminate collected impurities,
  • a control device consisting, in one part of an accelerating butterfly capable of closing off the principal device from the intake to the engine and in another part of an automatic three way valve by which a passage discharging downstream of the aforementioned butterfly is selectively connected to the auxiliary device when the butterfly is not closed, and when the butterfly is closed, and the speed of the engine is above a predetermined limit, to the exhaust of said engine.
  • annular gutter which forms a collector and is located under the lower free end of the aforementioned skirt and in which the inner rims forms part of the exit port.
  • exit port is integral with the bottom of the chamber and forms a long interior wall which supports the gutter, so that the inlet is made up of a removable cover supporting' the blade system, and the skirt, around which is formed a tranquilization chamber.
  • Apparatus as recited in claim 4 wherein the end of the chamber forms an annular reservoir in which the heavy particles in the mixture, collected in the gutter are received prior to being taken away.
  • valve consists essentially of a cylindrical chamber in the horizontal wall in which is an orifice connected to a previously mentioned passage and wherein the extremities (of the valve chamber) form two cut-off seats, the first leading to the chamber receiving the gaseous mixture conditioned in the auxiliary device, and the second leading to a tube connected to the engine exhaust, one of the aforementioned seats being selectively blocked off by a piston which moves axially in the valve chamber.
  • Apparatus as recited in claim 8 wherein the previously cited piston is normally held against the second cut-off seat by a return spring, and is moved against the first cut-off seat only when the butterfly is closed and when the motor speed is above a preselected limit.
