Definitions

  • ABSTRACT Injection of liquid fuel into a combustion-air passage through an ultrasonically vibrated nozzle formed in a body is prevented during the intervals between pulses of vibration by a ball valve element co-operating with a seat at the inlet of the nozzle: passage, this ball valve element being lifted off its seat during the vibration pulses by dynamic action resulting from the impulses it receives from the seat.
  • a solenoid may be provided which, when energized, acts on the valve element to lift it off its seat in opposition to the fuel pressure in the supply line and to the action of a return spring.
  • OSCILLATOR g E B I P 'PULSE GENERATOR ENGINE NOZZLES FOR THE INJECTION F LIQUID FUEL INTO GASEOUS MEDIA This invention relates to fuel injection devices and has for an object to provide improved nozzle arrangements for the injection of liquid fuel into a gaseous medium and may be applied to the injection of liquid fuel into the combustion air of a turbo-jet engine or other gas turbine or internal combustion engine.
  • an injection-nozzle arrangement which will hereinafter be referred-to as of the kind specified, and in which the fuel-injection nozzle is arranged to be subjected to vibrations, generally at ultrasonic or similar frequencies hereinafter called ultrasonic vibrations, the amount of fuel injected within a given period, for example within a revolution of the engine, being arranged to be controlled by varying the length of time in which the ultrasonic vibrations are applied, and thereby varying the length of time of injection, in each such period.
  • the present invention has for a more specific object to provide an arrangement of improved efficiency for effecting metered injection of liquid fuel into a flow of combustion air for a combustion engine with the help of a nozzle subjected to pulses of ultrasonic longitudinal vibrations, in which variation of the length of the pulses of vibration is utilized to vary the amount of fuel injected during each revolution of the engine.
  • the nozzle of an injection-nozzle arrangement of the kind specified is equipped at its inlet side with a valve, preferably a ball valve, which is arranged to normally close the inlet to the nozzle passage and thus to prevent the transfer of fuel to the combustion air but to be automatically operated to permit flow of fuel through the nozzle passage into the combustion air during the periods in which atomization is intended to be effective.
  • a valve preferably a ball valve
  • the valve is arranged to be normally held on its seat by fuel pressure, which may be assisted by spring action, although the valve could,
  • the fuel pressure tends to open the valve, which is normally held closed in this case by the opposite action of spring pressure.
  • Inertia forces will effect, during the times in which longitudinal vibrations are applied to the nozzle, opening of the non-return valve to permit the flow of fuel.
  • the opening of the valve may be arranged to be effected by magnetic action upon the valve element, for example with the help of a solenoid coil which is energized to permit injection, during the periods of vibration of the nozzle, and if desired such an arrangement may also be used to assist the above mentioned inertia operation.
  • the valve element is made wholly or partly of magnetic material and is so arranged as to be urged in a direction away from its seat by the magnetic action of the energized solenoid.
  • FIG. 1 is a somewhat diagrammatic axial section of one embodiment of an injection nozzle arrangement according to the present invention.
  • FIG. 2 is a fragmentary section illustrating a modification thereof.
  • 1 indicates a passage, which may be the induction line of an internalcombustion engine, or, for example, a passage leading from the air-compressor unit to the burners of a turbojet engine or other gas-turbine E.
  • a cylindrical nozzle portion 2 of an atomizer 3 is arranged to project with its end 2a through an aperture 4 in the wall of the passage 1 in such a manner as to provide substantially sealing co-operation while permitting mutual movement in the longitudinal direction of the portion 2.
  • the cylindrical portion 2 forms a socalled horn at one side of the large-diameter portion 5 of a resonant stepped vibration amplifier which is attached at the opposite surface of the portion 5 to one side of a piezoelectric transducer element 6.
  • a balancing body 7 is similarly attached to the opposite side of the transducer element 6, the arrangement being such that when an ac. voltage of a given ultrasonic frequency is applied to the piezoelectric element 6 by means of wires 9 and 10, resonant ultrasonic vibrations in the longitudinal direction of the cylindrical horn portion 2 are applied to the large-diameter portion 5 of the vibration amplifier.
  • horn portion 2 which is so dimensioned that maximum amplitude of oscillations is generated near the outer end 2a of the horn, which projects into the duct 1.
  • a fuel passage 11 Arranged coaxially in cylindrical horn portion 2 is a fuel passage 11, and in order to provide a spray nozzle, this passage 11 is formed, near the end 2a of the horn portion 2, with a restricted throat portion 12 which terminates in an outwardly flared cone portion 13, and the fuel passage 11 is formed at the opposite end of the throat portion. with a conical valve-seat surface 14.
  • the latter co-operates with a ball-valve element 15, which is normally held in contact with the seat 14 by a light spring 16. Liquid fuel under suitable pressure is admitted to the passage 11 by a transverse bore 17 formed in the portion 5 of the vibration-amplifier body, in which it is located near the nodal zone of oscillation.
  • the ball valve 15 will return on to its seat 14 under the combined action of the fuel pressure in line 17, 11 and of its return spring 16, and will thus prevent the escape of fuel into the air stream in the duct 1 during the intervals between the pulses of ultrasonic vibration of the nozzle.
  • the means for producing the required pulses of energization for the transducer element 6 may be substantially as described in the above-mentioned British Patent Specification No. 1,138,536. They are schematically indicated in FIG. 1 as a pulse generator P mechanically coupled to the engine E and having in addition a control input C. An oscillatory voltage of the frequency of the desired ultrasonic vibrations is produced by an oscillator O energized with current from a battery B, a pulse generator P geing operative to apply this oscillatory voltage to the wires 9 and in the form of the requisite pulses.
  • the illustrated embodiment also shows other means by which the ball valve 15 can be lifted off its seat 14 during the periods in which injection is desired, and which do not rely on the dynamic action of ultrasonic vibration of the cylindrical horn member 2.
  • these means can be used independently, they are used in the illustrated embodiment to increase the rate of flow permitted by the ball valve above the rate achieved when inertia action during the vibration is exclusively relied-upon.
  • They comprise a solenoid winding 18 arranged round the cylindrical horn portion 2 at a suitable axial position.
  • This cylindrical horn portion 2 is made of non-magnetic material, while the ball valve element 15 consists of magnetizable steel or other ferromagnetic material.
  • the winding 18 is so positioned that the valve element 15 will be lifted off its seat 14 by magnetic action when the solenoid winding 18 is energized.
  • the energizing current is preferably direct current; otherwise the cylindrical portion 2 should be made of a material having sufficiently low electric conductivity to avoid undue screening action by induced currents.
  • Suitable means are provided for timing the energizing current pulses for the winding 18 so as to coincide with pulses of ultrasonic-frequency current applied to the piezoelectric element 6. In the illustrated embodiment this is achieved by connecting the winding, via a rectifier arrangement 19, 20 across the wires 9, 10, as shown by chain-dotted connecting lines 9a,
  • FIG. 2 illustrates a further development of the invention which in experiments has been found to improve considerably the effectiveness of atomization at such high rates of fuel supply while retaining the advantages of ultrasonic atomization at lower rates.
  • the same references as in FIG. 1 are used as in FIG. 1, and in which the parts not shown may be as shown in FIG.
  • the stem 2 is formed with a stepped bore having two parts 11a, 11b, the latter being in the form of a counterbore, in which a valveseat member 14a forming the valve seat 14 and the nozzle passage 12, and a plug 21, which at its circumference is provided with helical grooves 22, are secured in axially spaced positions so as to leave between the plug 21 and the valve seat 14 a swirl chamber 23, in which the ball valve 15 is movable.
  • This valve is normally held on its seat 14 by the pressure of the liquid fuel in the chamber 23, no spring having been found necessary in the tests carried out.
  • An arrangement for injecting liquid fuel into combustion air for an internal combustion engine comprising: a nozzle body having an end face, a nozzle inlet in said body, a fuel passage for feeding liquid fuel to said nozzle inlet, a nozzle outlet in said end face, vibrator means which when energized apply ultrasonic vibrations to said nozzle body, energization control means for said vibrator means responsive to engine operating data to energize said vibrator means during engine operation to produce periods of vibration varying in duration according to the momentary fuel requirement of the engine, and a normally closed valve in said fuel passage which valve is open only when said ultrasonic vibrations are applied to said nozzle body thereby to atomize fuel from said end face.
  • valve is a solenoid valve.
  • valve is movable in the nozzle body in the longitudinal direction of the nozzle so that the valve is opened by its inertia when the nozzle is longitudinally vibrated.
  • valve seat is provided at the inlet to the nozzle passage and the valve is arranged to co-operate with said seat so as to be urged on to the seat by the pressure of the fuel fed to the nozzle.
