Definitions

  • the present invention relates to a method for starting a heater, in particular vehicle heater.
  • Such heaters used for example as auxiliary heaters or auxiliary heaters in motor vehicles are particularly critical in the starting phase in terms of pollutant emissions. Therefore, there is generally a desire to keep this starting phase as short as possible.
  • delivery rate is used here to refer to the quantity of fuel fed in per unit time, which could also be referred to as the fuel flow.
  • This fuel mixes with the naturally supplied combustion air in parallel, so that an ignitable mixture is formed, which is ignited in ideal circumstances within a few seconds. Since the fuel feed is generally time-controlled in known heaters, that is, this maximum amount of fuel is fed for a predetermined time, before then transferred to normal operation, but there is a problem that in the case where the provided mixture does not ignite, a excessive fuel accumulation is generated in the area of the heater. The consequence of this may be that liquid fuel from the heater or a combustion chamber of the same runs out or liquid fuel is ejected via the exhaust system in a subsequent restart attempt.
  • this object is achieved by a method for starting a heater, in particular vehicle heater, in which method with a first ignition phase fuel is fed with a first Zünd-flow rate in the heater and then if detected before the expiration of a maximum period of the first ignition phase ignition is started, a stabilization phase in which fuel is fed with a stabilizing flow rate in the heater, and then, if no ignition is detected before the expiration of the maximum period of the first ignition phase, a second ignition phase is started, in which fuel with a second Ignition flow is fed into the heater, which second ignition flow is less than the first ignition flow and as the stabilizing flow.
  • the ignition takes place, so the fuel / air mixture has started to burn. If this is the case, ie if there is a correct, fast starting process, then in a subsequent stabilization phase the flame is given the opportunity to spread further and to switch to a stable combustion state. However, if it is detected that there is no correct ignition, ie the fuel / air mixture has not started to burn, then a second ignition phase is entered, in which an attempt is still made to start the combustion, but with reduced fuel supply. In this way, a supersaturation of the heater with fuel in the starting phase can be avoided. This not only reduces the risk of leaking liquid fuel from a heater, but also leads to more favorable conditions in the event that a start attempt unsuccessful must be canceled and a new start attempt must be started.
  • the stabilization phase is started.
  • the stabilization flow rate fed into the heater during the stabilization phase can essentially correspond to the first ignition flow rate introduced in the first ignition phase. Furthermore, it is proposed that the first ignition delivery amount corresponds to the maximum delivery quantity. This means that in the first ignition phase, a fuel is operated in the heater or a combustion chamber of the same feeding system with maximum capacity.
  • the first ignition phase is started after a combustion chamber pre-conditioning phase has elapsed.
  • the object mentioned at the outset is further achieved by a method for starting a heater, in particular a vehicle heater, in which method fuel is fed into the heater in a first firing phase in a first firing phase and then, if before expiration a maximum period of the first ignition phase no ignition is detected, a second ignition phase is started, in which fuel is fed with a second ignition delivery in the heater, which is smaller than the first ignition delivery.
  • This generally designated 10 heater has a combustion chamber housing 12 in which a combustion chamber 14 is formed. Into this combustion chamber 14, the fuel required for the combustion is fed via a fuel feed pump 16. Further, a Combustion air blower 18 is provided, which feeds the air required for mixture formation in the combustion chamber 14.
  • a porous evaporator medium 20 is provided in the combustion chamber housing 12, for example in a region near the bottom thereof.
  • This porous evaporator medium 20 receives the initially liquid fuel, distributes it in its volume range, in particular under Kapillarré Quass, and gives the fuel in a vaporous configuration at its combustion chamber 14 side facing in this.
  • the porous evaporator medium 20 may be associated with an electrically operable heater 22 which, by increasing the temperature in the region of the porous evaporator medium 20, especially in the starting phase, ensures faster and more intense fuel evaporation.
  • an ignition device 24 for example a Glühzündux provided in the region of the combustion chamber 14.
  • a flame detection element 26 is provided, which can detect whether an ignition has taken place in the combustion chamber 14, that is, the combustion has started and thus a flame has occurred.
  • This flame detection element 26 can detect optically, but can also detect the temperature present in the region of the combustion chamber 14 or the combustion chamber housing 12, which of course also allows a conclusion as to whether an ignition has taken place and thus combustion has been started or not ,
  • the heater 10 is further associated with a drive device 28. This controls the operation of the various system components of the heater 10. Thus, this controls the fuel pump 16, as well as the combustion air blower 18 to initiate the required amount of combustion air and fuel to the combustion chamber 14 at the required time. Also the electrically energizable heater 22 and the ignition member 24 are under the control of the drive device 26. At the same time receives these inputs, for example, the detection signal of the flame detection element 26th
  • the heater 10 shown in FIG. 4 is only an example of a variety of different possible variations. It is understood that in various areas of this heater 10, the structure may be different than shown. However, it is important for the present invention that there are system areas which can initiate combustion air and fuel following combustion in a combustion chamber, which can generate the thermal conditions required for ignition, and which permit a conclusion as to whether ignition has taken place or not Combustion is present or not.
  • a conditioning phase designated t v in FIG. 1 is first started.
  • the thermal conditions required for successfully starting the heater 10 are generated in the region of the heater 10, in particular the combustion chamber 14.
  • the electrically energizable heating device 22 can also be operated in order to preheat the porous evaporator medium 20 and the region of the combustion chamber 14 or the combustion chamber housing 12 surrounding it.
  • a fixed period of time may be predetermined, wherein This fixed period of time may also depend on external conditions such.
  • a first ignition phase t Z1 is then started. From the beginning of this first ignition phase, fuel is directed toward the combustion chamber 14 by corresponding activation of the fuel pump 16, ie, in the case illustrated, it is introduced into the porous evaporator medium 20 and then vaporized in the direction of the combustion chamber 14.
  • the fuel pump 16 can be operated in this first ignition phase t Z1 so that the first ignition delivery quantity fed in this phase corresponds to a maximum possible delivery quantity m max .
  • combustion air is also conveyed in the direction of the combustion chamber 14 parallel to the fuel feed. This combustion air feed can for example also be started during the conditioning phase t v .
  • the ignition should take place even before the expiration of a maximum possible period of time t Z1 'of the first ignition phase t Z1 , which should lead to a corresponding output of the flame detection element 26.
  • this ignition takes place at time 2.
  • the first ignition phase t Z1 is then completed. Since the ignition has already started, 2 is then entered into a stabilization phase t s at this time.
  • fuel is conveyed with a stabilizing flow rate in the direction of the combustion chamber 14. This stabilizing flow rate may correspond, for example, to the first ignition flow. That is, even in the stabilization phase t s , the fuel pump 16 can be controlled so that it operates at maximum flow rate m max .
  • this stabilization phase t s is then transitioned to the normal combustion mode, which means that fuel m at a flow rate concerning is directed toward burning chamber 14.
  • a corresponding adjustment of the flow rate of the combustion air blower 18 can be made in order to provide the ideal fuel / air ratio for the then running combustion can.
  • a second ignition phase t Z2 is then entered in this case.
  • fuel is passed with a second ignition delivery in the direction of the combustion chamber 14, which corresponds to a delivery rate m min in the example shown.
  • This second ignition delivery is smaller than the first ignition delivery and is also smaller than the stabilization delivery, which corresponds to the first ignition delivery in the example shown.
  • the occurrence of the ignition and thus the start of the combustion are signaled at time 3 and even before the expiration of a maximum possible time period t Z2 'of the second ignition phase t Z2 by a corresponding sensor signal of the flame detection element 26 of the control device 28. It is then the second ignition phase t finished Z2 and then second to that ignition phase t Z2 subsequent stabilization phase s t occurred. In this stabilization phase t s , fuel with the stabilizing flow rate is then fed back into the combustion chamber 14 in order to ensure the fastest possible spread and thus also to support combustion stabilization in the combustion chamber 14.
  • the stabilization phase t s corresponds to that which is present in the sequence illustrated in FIG. 1, that is to say in that case in which the entry into the second ignition phase t Z2 does not occur was required.
  • the delivery rate here m max
  • the stabilization phase s t to the effect of differentiating whether from the first ignition phase t Z1 in the stabilization phase s t been entered, or from the second ignition phase t Z2.
  • the normal combustion mode is then transferred and fuel with the delivery amount m betr is conveyed.
  • this provided for the normal combustion plant flow rate m betr is greater than the provided in the start phase for the second ignition phase t Z2 second ignition flow rate m min .
  • the flow rate to be used in the normal operating phase following the time in Fig. 2 will, of course, depend on which heating power has to be provided.
  • Fig. 3 the case is shown in which when performing the start procedure according to the invention after the completion of the first ignition phase t 1 with the time t Z1 'and the complete expiry of the second ignition phase t Z2 with their maximum time t Z2 ' the occurrence the ignition could not be detected yet.
  • the fuel supply is then completely terminated according to the invention with the end of the second ignition phase t z2 , that is to say at time 2. That is to say, the two ignition phases t Z1 and t Z2 , together with their respective maximum time periods t Z1 'and t Z2 ', together define a safety time interval starting at the beginning of the fuel feed in at time 1.
  • the stabilization phase is followed, the flame is given in each case, the possibility under suitable conditions then spread as quickly as possible and stabilize. It has also been found that with respect to the total duration of the two ignition phases in the procedure according to the invention with lowering the fuel supply in the second ignition phase, the probability of a successful ignition is higher than in the case in which over these two phases or corresponding time period maximum possible Amount is encouraged.
  • an alternative variate of the method according to the invention may, for example, when the ignition t before the expiry of the first starting phase is detected Z1, this time of detection are already comparatively close t the end of the maximum possible period of time Z1 'this first ignition phase t is Z1, for example, in the last quarter of this maximum possible period of time t Z1 ', the entry into the stabilization phase t s be dispensed with and instead be transferred directly into the normal combustion mode.
  • the reason for this may be that a comparatively large amount of fuel is introduced into the combustion chamber immediately before the ignition occurs, which can then be burned on entering the normal combustion mode with reduced fuel feed and thus contributes to flame stabilization.
