Definitions

  • the invention relates to a Druckmessglühkerze for a diesel engine according to the preamble of claim 1.
  • a seal between the heating element and the plug body is provided in such a pressure measuring glow plug, which is formed of a metal membrane or of an elastomeric seal.
  • a metal diaphragm as a seal has the disadvantage of a stiff spring characteristic and a small spring travel, resulting in a component load.
  • An elastomeric seal on the other hand, is temperature sensitive.
  • a seal in the form of a bellows-type component is provided in the Druckmessglühkerze of the type mentioned between the heating element and the plug body.
  • a bellows-type seal has the advantage that an absolute tightness of the Druckmessglühkerze is guaranteed in the range of the heating element to the plug body relative to the applied combustion pressure.
  • the spring line can be influenced, that is to say selected in the desired manner.
  • Another advantage is that influences on the pressure sensor due to thermal stress during annealing and at different engine load conditions are minimal.
  • a pressure measuring glow plug for a diesel engine consists essentially of a plug body 3, 4, a heating rod 1 with a metallic or ceramic structure, which is arranged so as to be slidable in the plug body in the axial direction relative to the plug body 3, 4.
  • a pressure sensor 7, which may be arranged under a bias voltage by means of a sensor unit 5 between the heating element 1 and the plug body 3, 4 and is acted upon by the pressure prevailing in the combustion chamber of the cylinder pressure, wherein the heating element 1, the pressure in the combustion chamber of the cylinder to the pressure sensor 7 transmits.
  • the heating element 1 is slidably disposed in the axial direction relative to the plug body 3, 4, such that the pressure in the combustion chamber leads to an axial movement of the heating element 1 relative to the plug body 3, 4, through which the pressure sensor 7 is acted upon by a force.
  • the heating element 1 is mechanically fixedly connected via an extension tube with the pressure sensor 7 and a bellows 2, which is arranged as a sealing element between the heating element 1 and the glow plug body 3, 4 and ensures that the heating element 1 can move without friction in the plug body 3, 4 in the axial direction.
  • the bellows 2 which preferably consists of a metal material, mechanically connected to the heating element 1, for example, characterized in that on the front side of the cylindrical part of the bellows 2 to the heating element 1 towards a radially encircling Fillet weld or in the cylindrical part of the bellows 2 a radially encircling through-welding is provided.
  • the connection can be achieved in this area to the heating element by laser welding, crimping, swaging, soldering, pressing on, etc.
  • the plug body 3, 4 consists of two parts, namely a body upper part 3 and a body lower part 4, which are mechanically connected to one another.
  • the body lower part 4 is provided on the combustion chamber side with a sealing cone, via which the glow plug to the cylinder head seals the combustion pressure.
  • the bellows 2 is mechanically connected on the connection side to the body upper part 3. Also at this point, the bellows 2 may be formed with a cylindrical part which is pushed onto the outside of the shaft of the body shell 3 and is mechanically connected thereto. Other connection options are the same as in the connection of the bellows 2 to the heating element. 1
  • the front seal thus consists of a bellows-like component, which may be formed as a metal bellows.
  • the axial displaceability of the heating element 1 is ensured with extensive linearity of the force path characteristic.
  • the heating element 1 is thermally decoupled from the plug body 3, 4 and the heating element 1 is elastically supported in the plug body 3, 4 via the bellows 2.
  • About the bellows 2 can continue to be exercised a bias.
  • the heating element 1 is displaced in the axial direction to the sensor element 7, which sits at the connection end of the heating element 1 and in the form of a piezoelectric sensor, a strain gauge or a is formed similar measuring element.
  • the heating element 1 presses with a certain force on the sensor element 7, whereby a change in the sensor element lying force or voltage is effected, which is further processed via a suitable evaluation electronics to a measurement signal.
  • the advantage of the bellows 2 is that by a small spring characteristic, that is, a small spring force in a long way, the influence due to thermal stresses on the sensor element can be kept very small.
  • a small spring characteristic that is, a small spring force in a long way
  • the influence due to thermal stresses on the sensor element can be kept very small.
  • the glow operation of the Druckmessglühkerze or at different load and speed ranges continues to warm the heating element 1 between the two contact points on the sensor element and the combustion chamber, which would mean that too high a voltage is transmitted to the sensor element in a too rigid combustion chamber seal and thus a faulty measurement is the result.
  • the combustion chamber seal is designed to be too stiff, that is to say if the spring force is too high for a small distance, no measurable change would occur at the sensor element and thus no measurement signal would result.
