Definitions
- the invention relates to a method for actuating an ignition device for a operated with a fuel / combustion air mixture heater of a vehicle, in particular a heater or auxiliary heating, with a glow plug, which comprises at least one resistance element, wherein a resistance value of the at least one resistance element is detected ,
- the invention relates to a heater, in particular a heater or auxiliary heater for a vehicle, with an ignition device for igniting a fuel / combustion-air mixture supplied to the heater, wherein the ignition device has a glow plug which at least one Wider- Holding element comprises, wherein a resistance value of the at least one resistive element can be detected by a control device.
- ignition devices for vehicle fuel heaters operated with fuel / combustion air mixtures are used in a variety of applications. They can be used, for example, both in water heaters and in air heaters, which are designed as auxiliary heaters or as auxiliary heaters. So they are increasingly used both in passenger cars and commercial vehicles.
- auxiliary heaters or auxiliary heaters such vehicle heaters are often independent of the engine, that is, when the internal combustion engine of the vehicle is switched off, they are operated with liquid fuel.
- a glow plug is used to start the heater. This consists for example of a filament arranged in ceramic material, which serves as a resistance element.
- the resistance element can also serve to monitor a flame in a combustion chamber of the heater.
- the glow plug is not only used to start the vehicle heating, but can also perform a so-called flame detector function.
- the flame detector function is based on the knowledge that the resistance value of the resistance element can change as a function of the temperature present in the combustion chamber. So it is with the coupling of a control device with It is possible for the resistance element to gain information about the temperature in the area of the glow plug, so that ultimately flame monitoring is provided both during the starting process and during continuous operation of the vehicle heating system.
- a generic ignition device for carrying out the generic method is known for example from DE 102 32 164 B3.
- a resistance measurement is also performed each time before starting the heater in order to draw conclusions about the Glühken elaborate and / or surface temperature of the glow plug can. Therefore, the resistance value is measured before each start of the heater or before each start of a metering pump associated with the heater with a constant electrical power supply to the glow plug. This is to ensure that a sufficient Glühken intricate and / or surface temperature of the glow plug is achieved, even if different cold resistances are present on the glow plug.
- This type of resistance measurement before commissioning of the heater (calibration procedure) is necessary, as it can ensure the ignition quality and flame monitoring in steady-state combustion over the service life of the heater, taking the ambient conditions into account.
- the invention is therefore the object of developing the generic method and heaters such that the start time of the operated with a fuel / combustion air mixture heaters can be reduced.
- the inventive method is based on the generic state of the art in that the resistance value is detected at a time that depends on a switch-off of the heater.
- the calibration process can be moved to a hibernation of the heater.
- the calibration process is initiated immediately after the operation of the heater, that is to say now switched off, when there is no heat requirement.
- the calibration process is preferably not carried out.
- the heater start is thus without calibration process initiated in order to prevent a start time delay by the Einmessvorgang due to the renewed heat request in this case.
- the ignition device can be adapted to different applications.
- the ignition device is operated by the car battery.
- the car battery is usually in a sufficiently charged state at this time. As a result, the probability of failure due to the Einmessvorgangs is reduced because of an undervoltage of the car battery at start.
- the method according to the invention can be developed in an advantageous manner in such a way that the resistance value is detected at a point in time which lies at a predetermined time interval after the switching-off time of the heater.
- the calibration process or the detection of the resistance value is initiated only when a short cooling phase of the heater has elapsed immediately after the operation of the heater.
- further Schuansch applied as explained above.
- the method according to the invention may advantageously be developed in such a way that it comprises the step of controlling the frequency of detection of the resistance value after the heater has been switched off based on default parameters. Since it is not absolutely necessary to carry out the calibration process whenever the heater has been switched off, the frequency of the calibration process can be specified by certain parameters. By determining the frequency can be achieved advantageously by reducing the power consumption by the Einmessvorgang.
- the method according to the invention can be designed such that it comprises the step of detecting the resistance value before the heater is put into operation when the heater is put into operation for the first time. This prevents the case of insufficient
- the appropriate and required settings of the ignition device can be made before a first start-up of the heater to ensure a successful ignition by the glow plug.
- the inventive method can be implemented such that the detection of the 'resistance value before start-up of the heater is carried out according to one or more of a predetermined number of times after the heater was put into operation for the first time. This is determined by a freely selectable predetermined number of cycles for the specific application or for specific operating conditions of the ignition device. If the calibration procedures were carried out according to the number before the heater was started up, the calibration procedure will then be carried out subsequently, ie after the number has expired, after the heater has been put into operation.
- the detection of the resistance value or the calibration process before startup the heater are preferably carried out after the predetermined number or the number of cycles, if in the previous burning operation of the heater, a fault has occurred, for example, by the flame monitoring functionality or the
- Flame sensor function of the glow plug is detected.
- a disturbance may be, for example, a flameout in the burning operation of the heater under full load.
- the heater according to the invention builds on the generic state of the art in that the control device for actuating the ignition device is adapted to detect the resistance value at a time that depends on a switch-off of the heater. This results in the explained in connection with the method according to the invention properties and advantages in the same or similar manner, which is why reference is made to avoid repetition of the corresponding statements in connection with the inventive method.
- the heating device according to the invention can be developed in an advantageous manner such that the control device is suitable for detecting the resistance value at a point in time which lies at a predetermined time interval after the switching-off time of the heating device.
- the heating device according to the invention may also be developed in such a way that the control device is suitable for controlling the frequency of detection of the resistance value after switching off the heating device based on default parameters.
- the heater according to the invention can be formed so that the control device is adapted to detect the resistance value before starting the heater when the heater is first put into operation.
- the heater according to the present invention can be realized such that the controller is capable of performing the detection of the resistance value before the startup of the heater one or more times according to a predetermined number after the heater is first put into operation.
- FIG. 1 is a highly schematic representation of the heater according to the invention according to an embodiment of the invention, which is suitable for carrying out the method according to the invention.
- Figure 1 shows a highly schematic representation of the heater 12 according to the invention according to an embodiment of the invention, which is suitable for carrying out the method according to the invention.
- the heater 12 is a conventional, operated with a fuel / combustion air mixture heater 12, which forms a stand or auxiliary heating in this case and includes an ignition device 10 for igniting the fuel / combustion air mixture.
- the ignition device 10 has an annealing pin 14 with at least one resistance element 16.
- the glow plug 14 with the resistance element 16 is provided in a manner known to those skilled in a combustion chamber 24 of the heater 12.
- the ignition device 10 is coupled to an evaluation unit 20 assigned to a control device 18 via an electrical connection 22.
- the method according to the invention for actuating the ignition device 10 is carried out by the control device 18 in conjunction with the evaluation unit 20. So will according to the procedure
- Einmessvorgang or a resistance measurement of the resistive element 16 of the ignition device 10 only executed when an operation of the heater 10 ends, that is, immediately after the heater was taken out of service. In other words, the timing depends on
- the frequency of the calibration processes is preferably predetermined by the control device 18, since a calibration process does not necessarily have to take place after each shutdown of the heater 12. Therefore, based on suitable default parameters, the control device determines the frequency of the calibration procedures and accordingly carries out the calibration procedures only at predefined times.
- the control device 20 initiates the calibration operation before the heater starts up, that is, before the start of a metering pump associated with the heater.
- parameters can also be determined in advance, by the number of initiated Einmessvortician is set in the case of the first start-up of the heater that occur before re-commissioning of the heater 12.
