Definitions

  • the invention relates to a glow plug according to the generic term of claim 1.
  • Such a glow plug is known from DE-U-9 315 442.
  • a glow plug with a heating rod made of an inner pole and a glow tube in which a heating element is arranged, which with the inner pole is electrically connected, is also from DE-OS-4 133 338 known.
  • Such glow plugs can be in the form of rod glow plugs be trained and serve as a start-up aid for a air-compressing internal combustion engine.
  • Glow plugs are also used to support ignition used in heaters.
  • the object underlying the invention is therefore in creating a glow plug of the type mentioned at the beginning, which has a short heating-up time and a long service life.
  • the coating provided according to the invention acts as Surface protection of the glow tube, so that its wall thickness is considerable can be reduced.
  • the lower one thereby achieved Mass has the consequence that the glow plug according to the invention a short heating-up time, d. H. rapid heating shows what a faster readiness to start with diesel vehicles can be achieved, the machine with such glow plugs is equipped.
  • the extremely fast heating-up time is without Impaired lifetime of the glow plug achieved.
  • the training according to the invention also has the advantage that scaling of the glow tube material is achieved at the short heating-up times, a long afterglow and high temperatures is avoided, which means the use of glow tubes a material that is associated with low costs is. Cost savings also result from that the glow tube can have smaller tube wall thicknesses.
  • the coating provided according to the invention also becomes the glow tube surface due to its porosity enlarged and thus the heat radiation improved. It results a more even temperature distribution and a better one Preparation of the impacting fuel particles.
  • the single figure shows the embodiment of the invention Glow plug in an axial partial sectional view.
  • the embodiment shown in the drawing Glow plug according to the invention comprises a housing in which a Heating rod 1 is arranged, which has an inner pole 2 for connection to the electrical power supply and a glow tube 5 consists in which a heating element 3 is arranged, which with the Inner pole 2 is electrically connected.
  • the heating element 3 that made a heating and a control coil can exist, of which the Control coil connected to the inner pole 2 is in an MgO filling 4 embedded in the glow tube 5.
  • the glow tube 5 has at least in the area in which the Heating element 3 is provided, especially at its tip Coating 6 made of a material from a material group is selected, the NiCrAlY, CoCrAlY, CoNiCrAlY, NiCrAl, NiCr, NiCrFe and NiCrWCo.
  • This protective coating can consist of Ni22Cr10Al1Y, for example.
  • the coating 6 applied directly to the glow tube 5 has a thickness between 10 and 50 microns, in particular between 20 and 30 ⁇ m.
  • the glow tube 5 can the alloys commonly used to date, such as Inconel 600 or 601, but with a low one Wall thickness along its entire length or at its tip or from another, in particular less expensive alloy consist.
  • the glow tube 5 With a thinner wall of the glow tube 5 a faster heat transfer from the heating element 3 to the glow tube surface reached, the glow tube 5 is protected against scaling.
  • Heating rod or glow tube shape provided with a geometry, at the edges, corners and sharp transitions avoided and are rounded.
  • R1 denotes a place on which there is no coating. With a coating the entire heating rod tip is between R1 and R2 Radius of about 1 - 5 mm provided. In contrast, the radius R3 is about 3 to 5 mm.
