Definitions

  • the invention relates to a Druckmesswstab, in particular for a Druckmessglühkerze with an electric heating element and a pressure sensor to which a lying on the heating element pressure is transmitted.
  • a Druckmesswstab or Druckmessglühkerze with such a heating element is used in self-igniting internal combustion engines and in addition to the usual annealing function has a pressure measurement function, on the example of the pressure prevailing in the cylinder of the engine pressure can be determined.
  • the object underlying the invention is therefore to provide a Druckmesswstab, especially for a Druckmessglühkerze, which has a simple structure and is associated accordingly with low costs.
  • the pressure measuring device is integrated into the heating element, no special seals and guides are needed, which reduces the cost, and can be avoided by miniaturization, the natural frequency problem.
  • the invention furthermore relates to the use of the pressure-measuring heating element according to the invention in a pressure-measuring glow device and a pressure-measuring glow plug according to claims 7 to 10.
  • the single FIGURE shows a sectional view of the combustion chamber side part of a Druckmessglühkerze with the embodiment of the invention DruckmessSWstabes.
  • the Druckmessglühkerzenteil shown in the drawing essentially comprises a heating element 1, 2, 3, 4, which is arranged in a plug body 5 so that it projects axially thereof from the combustion chamber side.
  • the plug body 5 is sealed by a sealing seat 8 to the cylinder head of the internal combustion engine.
  • the heating rod 1, 2, 3, 4 consists of a heating element 1, which is preferably formed of a ceramic material, and a heating element 1 outside and in the combustion chamber side part with a certain play surrounding support tube 2.
  • a pressure sensor 3, for example, a piezoelectric Element may be and generates an electrical signal responsive to a mechanical stress, is arranged with a certain play between the heating element 1 and the support tube 2 such that a combustion chamber side lying on the heating element pressure is transmitted to the pressure sensor 3.
  • the support tube 2 may be made of a metal material, i. an electrically conductive material, so that it contacts the heating element 1, which is electrically contacted on the one hand via an inner pole 6, on the other hand via an outer pole 7 and thereby ensures the current return at the outer pole 7.
  • the support tube 2 is axially stretchable, clamped with the heating element 1 in the axial direction and forms together with the pressure sensor 3, a power circuit responsive to external pressures, such as the combustion pressures inside the cylinder of the internal combustion engine.
  • the axial extensibility of the support tube 2 can be adapted to the particular needs of the measurement task, that provided on the support tube 2 one or more bellows-like deformations are. Due to the formation of these bellows-like deformations, the elasticity in the axial direction can be adjusted as desired.
  • a press-in sleeve 4 is provided on the connection side in the support tube 2 so that it closes the power circuit.
  • the support tube 2 is crimped on the press-in sleeve 4, wherein the press-in sleeve 4 serves as a stable element, which makes it possible to compress the entire assembly of heating element 1, support tube 2, press-fit 4 and pressure sensor 3 tight in the plug body 5. This can be done by pressing the heating element 1 into the press-fit sleeve 4 or by radial force in the region of the press-in sleeve 4.
  • the contacting of the heating element 1 is effected by means of suitable lines which are integrated in the press-fit sleeve 4 or via a contact between the heating element 1 and the press-in sleeve 4.
  • the support tube 2 is arranged under an axial bias directly on the heating element 1 and is the pressure sensor 3 in the space between the heating element 1 and the support tube. 2
  • the support tube 2 has several functions, namely the construction of a bias voltage on the heating element 1, the power transmission to the pressure sensor 3 by the aforementioned support tube 2 is relieved, the support of the heating element 1, the power transmission of heating element 1 and the seal in the plug body fifth
  • the heating element 1 runs axially continuously from the combustion chamber side to the connection side to the inner pole 6 located there, it is also possible that the heating element 1 ends on the combustion chamber side of the pressure sensor 3 and this not as in the illustrated Embodiment in the form of a ring but as a solid, for example, cuboid or solid cylindrical element formed is.
  • the electrical connection is achieved instead of via the inner pole 6 in the illustrated embodiment via an external power supply.
  • the pressure sensor 3 consists for example of a temperature-stable piezoelectric quartz element or of an element of a piezoelectric functional ceramic.
  • a linear pressure / charge conversion can be set, which can be converted via a suitable electronics in a conventional voltage signal as the sensor output signal. Due to the thermally exposed mounting position, it is preferable to provide a temperature compensation of the measurement signal in the electronics.
  • the heating element according to the invention can be used in any Druckmessglü issued having a corresponding support for the heating element.
  • the heating element according to the invention in the connection-side region, in particular in the region of the press-in sleeve 4 in the holder fixedly arranged, for example, is press-fitted. It is also possible to weld the heating element in such a holder, in which case the press-in sleeve 4 does not necessarily have to be provided.
  • the pressure sensor of deformations of the holder e.g. the cylinder head of an internal combustion engine, in which the heating element is arranged, is decoupled.
  • the heater according to the invention operates in the following manner: Due to the axially strained arrangement of the support tube 2 on the heating element 1 is located on the pressure sensor 3, an axial bias. If the heating element is subjected to an external pressure, this is added to the already existing on the pressure sensor 3 bias in Form of an additional force. The resulting voltage signal is tapped and processed to a pressure applied to the heating element 1 reproducing pressure signal.
