Definitions

  • the present invention relates to a method for starting a vehicle heater and a vehicle heater.
  • the heat required in other system areas is generally provided by combustion of a mixture of combustion air and fuel.
  • a conveying device for example a metering pump
  • a porous evaporator medium the fuel is distributed and is then discharged in a vaporous form into a combustion chamber, where it mixes with the combustion air.
  • an ignition device is provided, which may be formed, for example, as a glow plug.
  • the power control can not be carried out in the desired manner, in particular if the electrical resistance is too high and thus the required current can not be achieved even with the maximum available voltage. This can lead to an undefined Vorglüh the ignition, with the result that when the liquid fuel is fed towards the combustion chamber assembly, the ignition of the combustion air / fuel mixture is not ensured.
  • the energy input into the ignition device is sufficient. Since the electrical energy introduced or consumed in the ignition element is substantially completely converted into heat energy, it can be ascertained by checking this energy whether suitable framework conditions have been created for the successful ignition. Only if it is ensured based on the monitoring of the registered energy that with regard to the operation of the ignition the necessary conditions for successful completion of the ignition process are created, fuel is actually directed toward the combustion chamber assembly, thus by providing the ignitable Mixture of fuel and combustion air to start the ignition.
  • the starting procedure is terminated.
  • the method according to the invention for starting a vehicle heater is used to perform a final inspection at the end of the manufacturing process of such a device. Since external conditions can be created in this state, which would always result in a correctly functioning ignition device that enough energy has been registered before or at the latest when the first predetermined time is reached, it can be concluded in the negative case that there are problems with such an ignition device is present. In order to avoid such problems during subsequent operational use, in such a system, the possibly faulty ignition device can be replaced with a new one. Of course, the same applies to devices that have been in operation for a long time.
  • the first checking operation does not indicate reaching the starting energy reference value until the first predetermined time
  • changing external conditions such as temperature, humidity and also the aging state of an ignition or the available on-board voltage can lead to temporarily present conditions in which the achievement of the desired energy input and thus a desired temperature to the first predetermined time is not guaranteed.
  • the starting energy reference value is not reached. If, in the second checking process, it is recognized that the desired energy input is not realized even up to the second predetermined time, that is to say the starting energy reference value is not reached, then it can be decided that the starting process is aborted and, for example, an error display is generated.
  • the period of time until which such a check is carried out may usefully be predetermined by the fact that the third predetermined time coincides with the second predetermined time.
  • the third checking process be carried out as soon as the first predetermined time point has been reached.
  • This vehicle heater is thus designed so that it can perform the method according to the invention shown above with all its possibilities and variations.
  • Fig. 1 is a vehicle heater, which here only with regard to the for Explanation of the present invention essential system areas is shown in a basic manner, designated 10.
  • the vehicle heater comprises a combustion chamber assembly 12 with a pot-like combustion chamber housing 14. This defines a combustion chamber 16.
  • a porous evaporator medium 18 may be arranged, via which liquid fuel is introduced by means of a Brennstoffzumoltechnisch 20 and a fuel conveyor 22, for example metering pump can. Due to its porosity, the porous evaporator medium 18 distributes the liquid fuel introduced by capillary action in its volume range and gives it on its side facing the combustion chamber 16 in vapor form to the combustion chamber 16 down.
  • an ignition device 24 is provided. This can be configured as Glühzünd21 and protrudes with his trained to generate the high temperatures required for ignition in a volume range in which such a required for igniting mixture of air and fuel is provided.
  • a control device 26 controls the operation of the various system areas of the vehicle heater 10.
  • the fuel conveyor 23 and of course a not further illustrated combustion air blower or the like under the control of this drive device 26.
  • the ignition device 24 is under the control of the drive device 26, wherein in If this ignition device 24 causes this activation, a voltage is applied to the ignition device 24.
  • the application of a voltage to the ignition device 24 causes a current flow due to the electrical resistance represented or provided by this ignition device 24.
  • the voltage and the current are elementary quantities for the operation of the ignition device 24, and are therefore a voltage determining device 28 and a Current determination device 30 is provided. These are shown in FIG. 1 as separate modules, but can of course also be implemented as system areas of the drive device 26.
  • the current determination device 30 may be designed to measure the flowing electric current, and likewise the voltage determination device 28 may be configured to measure the voltage applied to or applied to the ignition device 24.
  • the voltage determination device 28 may be configured to measure the voltage applied to or applied to the ignition device 24.
  • both the electrical power that is to say the heating power of the ignition device 24, can be determined, and the electrical energy introduced into the ignition device 24, which is essentially completely converted into thermal energy there.
  • the power is determined by the product of current and voltage, while the energy is determined by the integral of the power over time.
  • a pre-ignition phase is initiated at a start time, represented in FIG. 2 by tS.
  • the ignition member 24 is energized by applying a voltage and the resulting current flow, so that it heats up.
  • the objective is to heat the ignition member 24 in as short or acceptable a time as possible so that its surface areas effective for ignition have the required temperature, for example, in the range of 1100 ° C to 1200 ° C.
  • a power control can be carried out, in which the power is kept constant, for example, over the preglow phase, or is varied. With the power held constant, it is necessary to increase the voltage due to the temperature rising electrical resistance to compensate for the current falling with increasing resistance.
  • Vorglühphase without further consideration or monitoring of the current flow to apply a defined voltage.
  • it is necessary to take care in this Vorglühphase that on the one hand overheating of the ignition device 24 is avoided, and that on the other hand, the current flowing through this does not exceed a certain limit.
  • this is realized by virtually permanent monitoring of the current.
  • this can be determined so that damage to the ignition device 24 due to excessive current or too high temperature can be practically eliminated.
  • the pre-glow phase is started by applying a voltage to the ignition device 24 at the start time tS.
  • the application of the voltage results in the flow of a current I, which, as shown in FIG. 2, will then decrease with the temperature T gradually increasing.
  • the current I at the beginning of the pre-glow phase will also fall more sharply than at the end of the pre-glow phase.
  • the voltage and the current are sampled or determined permanently or at certain sampling times.
  • the heating power can then be determined from the values determined in this way, and by integrating the heating power over time, it is possible to determine the electrical energy introduced into the ignition device 24 and thus also the heat energy provided there.
  • the integral value of the heating power which essentially represents the registered energy
  • a predefined starting energy reference value at a predetermined point in time tB which can represent the completion of the preheating phase.
  • the preglow phase is correct and, for example, fuel can be started immediately to provide the ignitable mixture.
  • the point in time tB representing the end of the preheating phase can at the same time therefore also signify the beginning of the fuel feed phase. If necessary, a certain phase of delay could also be introduced here.
  • the excitation of the ignition device 24 can then be stopped or gradually shut down, or the ignition 24 can be aided energizing for a while until complete combustion is ensured and, for example, the heater 10 can be operated with maximum burner power.
  • the fuel supply is started only after or at this time tB. That is, the time for the preheat phase In principle, fixed, wherein, of course, depending on the external temperature or other environmental parameters, a variation in the length of the preglow phase can be introduced. In this way, it is ensured that there is sufficient time in other system areas to create the conditions necessary for ignition of the required quality.
  • the porous evaporator medium 18 could be assigned a heating device, which is also excited from the start time tS.
  • this procedure it is also possible in principle to make a permanent comparison between the registered electrical energy and the starting energy reference value. If, before reaching the time tB, this comparison leads to the knowledge that sufficient energy has already been entered, it is nevertheless possible to proceed as described above, ie the preheating phase is ended only when the time tB has been reached and subsequently also fuel is fed in.
  • the starting procedure can be aborted and, for example, an error warning is generated.
  • This procedure is particularly advantageous when the starting procedure according to the invention in the quality inspection after the manufacturing process such a heater 10 is performed. Since basic conditions are created in such a quality check, which would have to lead, if the ignition device 24 functions correctly, to sufficient electrical energy being introduced in this pre-glow phase, such a termination or fault indication would indicate that possibly in the area of the ignition device 24 a problem is present.
  • the ignition device 24 may have an outside of the tolerances specified per se lying electrical resistance, which does not have the desired heating power and thus not the desired entry of electrical energy at maximum possible applied voltage.
  • the cancellation of the start procedure and, for example, the generation of an error indication can also be realized in heaters that are already in operation.
  • this monitoring result leads to the starting energy reference value having been reached even before reaching a further predetermined time tV, then, for example, fuel can be fed in immediately when this reaching is detected, ie the delivery device 22 is energized in order to trigger the ignition process ,
  • the delivery device 22 is energized in order to trigger the ignition process
  • it could also be thought of using a slightly changed starting energy reference value for the phase following the time tB. For example, this could be slightly increased to account for the longer preheat phase.
  • the starting energy reference value is not reached or exceeded even if the ignition device 24 continues to be energized up to the point in time tV, then the presence of a malfunction can actually be inferred, and thus the starting procedure possibly terminated, generating an error indication.
  • FIG. 3 A development of the method described above is shown in FIG. 3.
  • the extended pre-glow phase that is to say after exceeding the second point tB with the starting energy reference value not reached, not only the energy then introduced up to a respective time is compared with this value. Rather, the current is monitored for its change.
  • the excitation of the ignition element 24 is ultimately continued, either until the time tV has been reached, or until is determined during the energy check that the starting energy reference value is reached or exceeded. In the former case, the excitation is terminated and the starting procedure is terminated, while in the second-mentioned case, then continued with the introduction of fuel.
