Definitions

  • the invention relates to a method and a device for generating a finely divided fuel mist, in particular for providing a good combustible fuel-air mixture for a heater of a motor vehicle.
  • Sputtering systems are known from the prior art, for example, which produce a fuel-air mixture with a high-pressure spray nozzle, which is described for example in DE 102 07 311 A1.
  • One of the disadvantages of these devices is that the atomizer nozzle can become clogged with, for example, dirt particles, whereby the production of a finely divided fuel-air mixture is no longer guaranteed.
  • such atomizers have the disadvantage that the fuel must be forced through the nozzle at a high pressure in order to achieve a satisfactory fuel-air nebulization, which is also referred to as fuel-air aerosol.
  • a fuel-air aerosol is achieved by means of a Ultraschallzerstäuberdüse.
  • This nozzle has an atomizer housing, in whose one end face a plurality of injection openings are provided which lead from a pressure chamber in the interior of the atomizer housing to the outside.
  • the under pressure in the pressure chamber of the Ultraschallzerstäuberdüse located fuel exits through the spray openings as a fine fuel jet and is excited by a patch on the Ultraschallzerstäuberdüse ultrasonic vibrator to a decay in fuel droplets, creating a fuel-air mixture.
  • the injection ports may clog so that the required throughput of a fuel-air mixture can not be achieved.
  • DE 39 42 747 A1 describes an ultrasonic atomizer in a vehicle heater.
  • the ultrasonic atomizer has an ultrasonic transducer, a projecting from this rod and at the end of the rod to a Zerstäuberteller.
  • the fuel is supplied to the atomizer plate through a fuel line through an inner passageway extending through the protruding bar.
  • a Ultraschall ⁇ atomizer is described with an ultrasonic transducer having a substantially axial ⁇ symmetrical metal body.
  • the ultrasonic vibrator is designed with an elongated area, which is provided at its free end with a Zerstäuberteller.
  • the elongated region is formed with an axial passage through which liquid fuel from a fuel supply is applied to the outer surface of the Zerstäubungstellers.
  • the atomization of the fuel is carried out by means of ultrasound, whereby a fuel-air-aerosol is formed by the formation of capillary waves on the surface of the deposited on the atomizer plate fuel.
  • the ultrasonic atomizer - in particular the ultrasonic vibrator - is provided with channels for supplying fuel, which increases the manufacturing cost of such a component.
  • Another disadvantage is that the pulsating through the pumping interval fuel supply must be attenuated with complex means.
  • the invention has for its object to provide an apparatus and a method for producing a finely divided fuel spray, wherein the above-mentioned disadvantages are avoided, in particular a fuel spray is generated, with which an improved combustion process can be achieved.

  • the ultrasonic vibrator is operated at a frequency such that detach at the fuel surface smallest fuel particles and a floating fuel mist (spray) is formed in the chamber.
  • the ultrasonic vibrator is preferably provided with electrical connections, so that electrical excitation energy can be supplied. In this case, the ultrasonic vibrator is put into mechanical vibration during operation.
  • the ultrasonic vibrator is excited at a frequency which is in the megahertz range.
  • the ultrasonic vibrator generates ultrasonic vibrations, which can be caused by the liquid fuel, which can be, for example, gasoline, diesel oil or kerosene, to the fuel surface - ie Interface fuel-air - be routed.

It is particularly advantageous that a large volume flow of the finely divided fuel mist can be generated by the inventive method, at the same time very small fuel droplets can be achieved, which is very advantageous for the combustion process.
  • a fuel spray with a very large concentration of fuel particles is created.
  • the resulting fuel-air mixture outside the chamber for a combustion process for example in a heater of a motor vehicle, is suitable.
  • the fuel column h In order to produce a satisfactory fuel spray in the chamber, it is important that there be a sufficiently high fuel column above the ultrasonic vibrator. It has been found that with a height of the fuel column h in a range of 15 mm>h> 50 mm, preferably in the range of 20 mm>h> 40 mm, a very finely divided and homogeneous fuel mist can be achieved. To ensure this, fuel is simultaneously replenished into the chamber during operation via a fuel supply.
