Definitions

  • the invention relates to a glow plug according to the preamble of claim 1.
  • Such a glow plug which is known for example from DE-OS 41 33 338, can be designed in the form of a rod glow plug and is used, for. B. as a starting aid for an air-compressing internal combustion engine.
  • Glow plugs are also used to support ignition in heaters.
  • the object underlying the invention is therefore to create a glow plug of the type mentioned which has a short heating-up time and a long service life.
  • the coating provided according to the invention acts as surface protection for the glow tube, so that its wall thickness can be reduced considerably.
  • the resultant lower mass results in the glow plug according to the invention having a short heating-up time, i.e. H. rapid heating shows, whereby a faster readiness to start can be achieved in diesel vehicles whose machine is equipped with such glow plugs.
  • the extremely fast heating-up time is achieved without affecting the life of the glow plug.
  • the design according to the invention also has the advantage that scaling of the material of the glow tube is avoided with the short heating times achieved, long afterglow and high temperatures, which makes it possible to use glow tubes made of one material, which is associated with low costs.
  • a cost saving also results from the fact that the glow tube can have smaller tube wall thicknesses.
  • the coating provided in accordance with the invention also increases the glow tube surface area due to the porosity and thus improves the heat radiation. This results in a more uniform temperature distribution and better processing of the fuel particles that hit it.
  • the single figure shows the embodiment of the invention Glow plug in an axial partial sectional view.
  • the embodiment of the glow plug according to the invention shown in the drawing comprises a housing in which a heating rod 1 is arranged, which consists of an inner pole 2 for connection to the electrical power supply and a glow tube 5, in which a heating element 3 is arranged, which has the inner pole 2 is electrically connected.
  • the glow tube 5 has at least in the area in which the heating element 3 is provided, in particular at its tip, a coating 6 made of a material selected from a group of materials, the NiCrAlY, CoCrAlY, CoNiCrAlY, NiCrAl, NiCr, NiCrFe and NiCrWCo includes.
  • This protective coating can consist, for example, of Ni 22Cr 10Al 1Y.
  • the coating 6, which is applied directly to the glow tube 5, has a thickness between 10 and 50 ⁇ m, in particular between 20 and 30 ⁇ m.
  • the glow tube 5 can consist of the alloys conventionally used hitherto, such as Inconel 600 or 601, but with a low wall thickness over its entire length or at its tip, or of another, in particular less expensive, alloy.
  • a suitable heating rod or glow tube shape is provided with a geometry in which edges, corners and sharp transitions are avoided and rounded.
  • R1 denotes a place where there is no coating.
  • the entire heating rod tip has a radius of about 1 - 5 mm between R1 and R2.
  • the radius R3 is approximately 3 to 5 mm.
