Definitions

  • the so-called pre-heating step the electrical feeding of the glowplug is caused by the activation of the starting changeover switch of the engine, and lasts up until the starting of the engine.
  • the recent processes for electrical feeding of glowplugs also include, after the pre-heating step, a so-called post-heating step in which the feeding of the glowplug is maintained during a period which may persist for up to 180 seconds after the starting of the engine.
  • the post-heating step enables the pollutant emissions and noise emissions of the engine to be minimised.
  • a feed device of a glowplug 21 enabling a process to be implemented for feeding a glowplug 21 in accordance with the invention is represented in Figure 1 .
  • the glowplug 21 is mounted on the cylinder head of an engine and exhibits a heating finger extending into a combustion chamber of a heat engine which is not represented.
  • the chopping signal enables the mean electrical power of the electric feed current to be controlled.
  • the duty cycle of the chopping signal enables a mean electrical power of the electric feed current, the so-called mean feed power, to be defined. More particularly, when the duty cycle is equal to one, the mean feed power is equal to the maximum feed power, and when the duty cycle is zero, the mean feed power is zero.
  • the mean feed power enables the temperature of the resistive element to be raised. More particularly, in the course of the post-heating step 29 the mean feed power enables the resistive element to be set at a temperature greater than 900°C, e.g. of the order of 950°C. Afterwards, in the advantageous embodiments in which the mean power is constant in the course of the pre-heating step 28 the resistive element is maintained at the same temperature.
  • the final step 30 of controlled cooling enables the service life of a glowplug 21 to be increased considerably. Indeed, the fact of retarding the cooling of the resistive element of the glowplug 21 enables a uniform solidification of the resistive element to be ensured, so as to avoid deteriorations of the resistive element that may be due to an excessively rapid cooling of the resistive element.
  • a process for electrical feeding of a glowplug 21 in accordance with the invention therefore enables the service life of the glowplug 21 fed in accordance with such a process to be increased.
