  • the measurement of the glow plug temperature over the glow plug resistance separates as a way of identifying the Glow plug temperature due to the tolerances of the glow plugs in terms of their resistance because of the existing real Tolerances and different dynamic behavior out. Calibration of the glow plugs is over also unthinkable, since it involves large-volume components is.

  • the control of the physical model 4 with a fixed value. It is known that glow plugs during engine operation at least for diesel engines with direct injection except in marginal areas of low speed and very high load higher than the conditions with the engine stopped Have energy needs to set the target temperature of the glow plugs too hold. It is customary, the control electronics 12 so train that energy supply to the glow plugs so It is regulated that the glow plug temperature is independent of the engine operating conditions is maintained. This can be done at running engine and thus usually higher energy flow assumed the glow plugs as the engine is stationary be that the glow plugs have exactly the target temperature. The correction module 13 can be easily detected for this If the physical model 4 to one of the setpoint temperature force appropriate state.
  • an even more accurate illustration of the actual Glow plug temperature required by the physical model 4 or in engines with indirect injection or other engines where the above-mentioned simple limit of the model is not sufficient by a fixed value may be the additional positive or negative energy input initially recorded by measurement and in correlation with the Engine control unit 1 or the glow control 2 available parameters, such as B. the injected fuel amount, the Speed, the inner moment, the air, engine, water or Oil temperature can be set. Due to the then received Data becomes an algorithm or a mathematical one Model created and integrated into the correction module 13, so that this the drive signal parallel to the Glühkerzenbestromung modified so that the physical model 4 follows the actual temperature at the glow plug.
