Definitions

  • the present invention relates to a method for controlling a Glühzündorgans a heater, in particular a vehicle heater.
  • the DE 44 46 113 A1 discloses a method for driving a Glühzündw, in which a Glühzündw is driven to obtain a predetermined temperature with a certain duty cycle, ie the available voltage corresponding to the duty cycle pulsed applied to the Glühzündux.
  • the duty cycle is selected as a function of the existing supply voltage, so that with decreasing supply voltage, the duty cycle increases up to a value of 100%.
  • Elementary in the procedure according to the invention is that an attempt is first made to set the voltage to be applied to a glow-igniting element in the pre-glowing phase to an optimum setpoint value for a particular Glühzündorgan. In association with such a setpoint value, a basic preheating time and a basic pre-glowing duty factor are then used to pre-stress the Glühzündorgan in a defined manner.
  • the basic Vorglühdauer and / or the Grund Vorglühtastrise be given based on at least one operating parameter, this at least one operating parameters can reflect the ambient temperature.
  • this at least one operating parameters can reflect the ambient temperature.
  • the temperature prevailing in the area of the heater itself can be taken into account, so that, for example, when the heater is to be put back into operation after a short standstill phase and it is still at a relatively high temperature, a correspondingly shortened preglow phase with possibly correspondingly reduced preglow power is selected can be.
  • step b) when the deviation determined in step b) exceeds a predetermined limit value, the application of a preglow voltage to the Glühzündorgan is prevented.
  • the corrective measures that are to be carried out according to the invention when a certain voltage level can no longer be achieved can be achieved, for example, by determining the corrected pre-glow duration in step c) by determining a correction term based on the deviation determined in step b) and adding the correction term Basic pre-heating duration is determined and / or that in step c) the corrected basic pre-ignition duty cycle is determined by determining a correction term based on the deviation determined in step b) and adding the correction term to the basic pre-ignition duty cycle.
  • a heating system as it can be used for example as a heater or heater in a vehicle use, shown very schematically.
  • This heating system 10 includes a generally designated 12 heater.
  • combustion air is mixed with vaporized or atomized fuel and brought to combustion.
  • a Glühzündit 14 is provided in a burner area. This is, as well as other controlled system areas of the heater 12, under the control of a drive device 16.
  • the drive device 16 is fed to apply an excitation voltage to the Glühzündux 14 from an on-board voltage network 18.
  • the drive device 16 Based on the on-board voltage generated so when, for example, at time t 0 a command to start the preheating is output, the drive device 16 a VorglühHar which is applied to the Glühzündit 14.
  • a value U s is selected as the preglow voltage setpoint, which value is adapted to the specific structural design of a particular glow plug pin 14 and ensures that it can not be overloaded, at least in normal operation.
  • a basic preglow time is also predetermined, during which this preglow voltage is applied to the glow-ignition pin with the desired value U s .
  • this basic pre-heat duration is represented by the time interval between the time t 0 and t g .
  • a basic Vorglühtastrich is selected in association with the setpoint U S , so that this Vorglühmechanical U is applied to the Glühzünd21 14 with the value U S and the basic Vorglühtastêt endeavor during the basic Vorglühdauer.
  • the glow on the Glühzündux 14th voltage to be reduced to a reduced ignition value U z .
  • the on-board voltage provided by the on-board voltage network 18 Due to the fact that a large number of additional consumers of electrical energy is present in modern motor vehicles, it is possible, especially at comparatively low outside temperatures, for the on-board voltage provided by the on-board voltage network 18 to be insufficient for the voltage provided for the preglow phase with the setpoint value To provide U S. If an instruction for preheating is thus generated in such a state, then the drive device 16 tries to apply a sufficiently high voltage to the glow plug pin 14, but the actually applied preglow voltage will be somewhat lower than the setpoint value U S. For example, assume that the actual pre-glow voltage is at a value U 1 which is below the setpoint U S by a difference ⁇ U 1 .
  • FIG. 3 shows a characteristic map with a characteristic curve K, where respective voltage difference values ⁇ U are assigned time correction terms ⁇ t. If, in the case described above, the actually applied Vorglühwood U 1 by the difference .DELTA.U 1 below the setpoint voltage U S , so from the map shown in FIG. 3, a corresponding correction term .DELTA.t 1 is taken and added to the Grund-Vorglühdauer added. There is therefore, as shown in Fig. 2 seen for the termination of the preheating, a time t 1 at which the voltage on the ignition voltage U z is lowered.
  • the correction of the pre-annealing time or the pre-annealing duty cycle can also be carried out by calculating a correction term in which a correction factor, which specifies how many seconds per volt voltage deviation the pre-glow period is to be extended, is multiplied by the determined voltage deviation.
  • the correction term thus obtained can then be added to the Grund Vorglühdauer. The same applies, of course, again for the duty cycle.
  • the basic pre-heat duration and the basic pre-calcination duty cycle depending on various parameters, e.g. can be selected from the ambient temperature or the temperature in the range of the heater 12, also such a correction factor, which is shown in the illustration of FIG. 3 is substantially reproduced by the slope of the characteristic K, depending on such external circumstances, so that, for example, even when higher ambient temperatures or higher temperatures are present in the region of the heater 12, smaller corrections are made if the setpoint voltage is undershot than in a case in which comparatively low temperatures prevail.
  • the selection of the different basic quantities, correction terms and correction factors must ensure that even under the most unfavorable circumstances, i. For example, at very low ambient temperatures or very cold Glühzünd21 14, the required temperature can be achieved at the beginning of the Vorglühphase within the time then predetermined for this Glühzündphase time.
  • the present invention ensures that overload of the glow-igniting pin can be prevented.
