Definitions
- the invention relates to a method for adjusting a temperature of a glow plug, in particular for igniting a fuel-air mixture in an internal combustion engine, wherein the temperature of the glow plug is adjusted in response to a resistance of the glow plug by means of a control, and a control device for carrying out the method ,
- Glow plugs which are used in internal combustion engines to ignite a fuel-air mixture are preheated in a cold state before their temperature is so high that it is sufficient for the ignition of the fuel-air mixture.
- the glow plug has for this purpose a heater, which acts on the cold glow plug in a short period of 1 to 2 seconds with an excessive heating voltage, so that the glow plug is overstressed at this time.
- the tip of the glow plug After completion of this so-called push phase, the tip of the glow plug has reached a temperature of about 1000 ° C, while the remaining part of the glow plug still has a temperature which is well below this temperature of 1000 ° C.
- the temperature of the glow plug in the preheating phase represents an input variable for a control with which the temperature of the glow plug is adjusted when it has reached a stationary temperature profile.
- this input variable for the control is determined during a transient process, this leads to errors in the subsequent control. Disclosure of the invention
- the invention is therefore an object of the invention to provide a method for controlling the temperature of a glow plug in which the occurring during the preheating temperature overshoot is reliably prevented, although the glow plug is subjected to an excessive heating voltage.
- the object is achieved in that the temperature in a preheating the glow plug, in which an overvoltage is applied to the glow plug, is regulated.
- the advantage of the invention is that the annealing temperature over the entire annealing of the glow plug is now modulated with high quality and the control of the annealing temperature at each time the annealing phase, advantageously also in the preheating (push phase) takes place, in which the heater of the Glow plug, the cold glow plug in a short period of 1 to 2 seconds applied to an excessive heating voltage.
- This allows better control of the preheat phase both at the key start and during long startup phases.
- the development effort is reduced since no application for a controlled preheating is necessary and the input parameters are determined only once and maintained for the life of the glow plug.
- the measured resistance of the glow plug is added to the resistance difference and fed to the sum of the control formed from the measured resistance and the resistance difference.
- the measured heat resistance is increased by a proactively determined amount, which corresponds to the temperature actually occurring during the preheating phase in the glow plug.
- the resistance difference consists of several, in particular summed, partial resistance differences, wherein each partial resistance difference is determined as a function of at least one operating parameter of the glow plug.
- a first partial resistance difference is determined as a function of an energy content of the glow plug which it has at the time of starting the annealing process.
- the initial characteristic of the glow plug at the time of starting the annealing process is taken into account in the determination of the difference in resistance.
- the energy content of the glow plug is characterized by an initial resistance, an initial amount of heat or an initial power.
- the heat balance of the cold glow plug is considered before Clearbestromung. Since, for example, in a cold glow plug, the initial resistance is very small, while in a glow plug, which was once heated, the initial resistance is greater, it is ensured that always the correct input variable is used in the determination of Wderstandsdifferenz.
- a second partial resistance difference is determined as a function of a temperature setpoint of the glow plug, which it should have at the end of the annealing process. By including the temperature setpoint, it is ensured in the modeling that the final state of the glow plug in the form of the desired temperature value, which corresponds to the temperature which is to be set at the end of the preheating phase of the glow plug, is taken into account. Furthermore, a third partial resistance difference is determined as a function of an output temperature of the glow plug which it has at the time of starting the annealing process. Since the glow plug at different temperatures at the first start has a different behavior, this is
- Output temperature of the glow plug also considered, in order to model the correct behavior of the glow plug.
- the starting temperature corresponds to an ambient temperature of the glow plug at the time of starting the annealing process.
- the ambient temperature of the glow plug is easy to determine, since motor vehicles in whose internal combustion engines the glow plugs are installed have an outside temperature display. Thus, it is possible to dispense with further hardware for determining the ambient temperature.
- a fourth partial resistance difference is determined as a function of an annealing process of the glow plug that is directly preceded by the start of the annealing process.
- the state of the glow plug is taken into account, which has the glow plug when the ignition of the engine, which pulls a heating of the glow plug by itself, has taken place, but this short time later turned off again and was activated within a few moments again.
- the immediately preceding annealing process is characterized by its annealing duration or annealing energy, wherein a factor is determined in dependence on an initial resistance of the glow plug, which is multiplied by the fourth partial resistance difference and added to the resistance difference.
- the annealing time which corresponds to the duty cycle of the glow plug, allows conclusions about how much energy is still stored in the glow plug.
- the fourth partial resistance difference which was determined in dependence on the start of the annealing preceding annealing time, added to the resistance difference.
- a Temperaturistwert determined which is subtracted from the temperature setpoint 5, wherein the thus determined Temperature difference of the control is supplied from which a drive voltage for the glow plug is determined to set the desired temperature setpoint.
- a development of the invention relates to a control device for setting a temperature of a glow plug, in particular for igniting a fuel-air mixture in an internal combustion engine, which adjusts the temperature depending on a resistance of the glow plug by means of a control.
- a control device for setting a temperature of a glow plug, in particular for igniting a fuel-air mixture in an internal combustion engine, which adjusts the temperature depending on a resistance of the glow plug by means of a control.
- means are provided which regulate the temperature in a preheating phase in which an overvoltage is applied to the glow plug.
- Figure 1 Schematic representation of the arrangement of a glow plug in an internal combustion engine
- Figure 2 schematic representation for modeling the temperature of a glow plug in a fast preheat phase
- FIG. 3 Temperature-time diagram without and with predictive temperature modeling
- a glow plug 2 protrudes into the combustion chamber 3 of the diesel engine 4.
- the glow plug 2 is on the one hand connected to the Glühzeit Kunststoff réelle 5 and on the other hand leads to a battery 6, the glow plug 2 with the rated voltage of 1 1, for example Volts drives.
- the Glühzeit tenu réelle 5 is connected to the engine control unit 7, which in turn leads to the diesel engine 4.
- the glow plug 2 is preheated by the application of an overvoltage in a, also referred to as a push phase preheating, which lasts 1 to 2 seconds.
- the electrical energy that is supplied to the glow plug 2 is thus converted into heat in a heating coil, not shown, which is why the temperature at the top of the glow plug 2 rises steeply.
- the heating power of the heating coil is adjusted via the electronic Glühzeit Kunststoff 5 to the requirement of the respective diesel engine 4.
- the fuel-air mixture is conducted past the hot tip of the glow plug 2 and heats up. Associated with an intake air heating during the compressor stroke of the diesel engine 4, the ignition temperature of the fuel-air mixture is achieved.
- the glow plug 2 has different glow phases. As already shown, in a preheating phase, which takes 1 to 2 seconds, the cold glow plug 2 is supplied with an overvoltage, which is above the nominal voltage of the glow plug 2. During this short period of time, the tip of the glow plug is heated to approximately 1000 ° C, while the remaining part of the glow plug 2 is still below this temperature, thereby forming a transient temperature profile within the glow plug 2.
- This preheating phase is followed by a heating phase of the glow plug 2, in which the transient temperature distribution compensates for a steady temperature distribution over the entire glow plug 2. Such a heating phase usually takes approximately 30 seconds.
- the resistance difference is adapted dynamically during the heating-up phase. This is followed by the annealing phase, in which a steady temperature distribution over the entire glow plug is ensured.
- FIG. 2 shows a schematic diagram for the temperature modeling of the glow plug 2 during the rapid preheat phase is integrated as software in the engine control unit 7 or the Glühzeit Kunststoff Technology 5 and is taken into account in a temperature control of the glow plug.
- a control input variable for the general temperature control of the glow plug 2 over the entire annealing process is provided by the engine control unit 7, a temperature setpoint TDES.
- a resistance R m of the glow plug is measured, which represents a value for the current temperature at the glow plug 2.
- This measured resistance R m is determined at each Bestromungsvorgang, which takes place at regular intervals.
- this measured resistance R m is added to a resistance difference AR, which is determined by means of a predictive model 8.
- This predictive model 8 models the temperature of the glow plug 2 in the rapid preheat phase.
- an initial resistance R 0 i of the glow plug 2 is determined.
- This initial resistance R 01 is fed to a characteristic curve 9, which was determined during stationary operation of the glow plug. From this characteristic curve 9, a first partial resistance difference ⁇ R1 is determined on the basis of the measured initial resistance R 0 i.
- Another input variable of the predictive model 8 is the temperature setpoint
- TQES provided which identifies the end temperature of the glow plug 2 to be reached.
- This temperature setpoint T DE swird is also given to a further characteristic curve 10 as an input variable, from which a second partial resistance difference ⁇ R 2 is determined.
- the thus determined partial resistance differences ⁇ R1 and ⁇ R2 are added in block 14.
- Glow time / annealing energy E (E U * I * t) of, the current annealing immediately preceding the annealing process of the glow plug 2 taken into account.
- a fourth partial resistance difference ⁇ R4 is determined with the aid of a fourth characteristic curve 12. Since, due to the annealing time / annealing energy E of the immediately preceding annealing, the resistance of the glow plug 2 changes when the heat that has built up during the previous annealing process within the glow plug 2 has not yet cooled, the resistance R 0 i is another characteristic 13, which as a result yields a factor F which is multiplied in block 22 by the fourth partial resistance difference ⁇ R4.
- the factor F is selected so that when the time measured initial resistance R 0 i is greater than a predetermined threshold value of the Wderstandes R 0 i, that is equal to the first The factor F tends towards the value zero, when the initial resistance R 0 i is smaller than the predetermined threshold value of the resistor R 0 i. This requires that the input variables of the annealing time / annealing energy E with the associated change in the initial resistance R 0 i are only used to determine the resistance difference ER when the glow plug 2 still has a correspondingly high resistance due to a preceding annealing process, which goes along with a changed temperature of the glow plug 2.
- the fourth partial resistance difference ⁇ R4 is added in block 16 to the above-described partial resistance difference ⁇ R1, ⁇ R2 and ⁇ R3, resulting in a resistance difference ⁇ R corresponding to a predetermined temperature occurring at the end of the preheating operation on the glow plug 2.
- the determined in the predictive model 8 resistance difference ER is added in block 17 to the measured resistance R m .
- This sum of the difference in resistance ⁇ R and the measured resistance R m is fed to a characteristic curve 18 in which the heat resistance is plotted against the temperature.
- This characteristic curve 18 is a characteristic determined individually for each glow plug 2 at a steady-state temperature distribution, since glow plugs have an independent transfer function due to production tolerances.
- a base temperature TBAS of the glow plug 2 is determined.
- This base temperature T B AS is adjusted in block 19 with a heat conduction model, which takes into account the extent to which there is a temperature difference between the interior of the heater of the glow plug 2 and the surface temperature of the glow plug 2.
- a temperature difference is supplied in block 19 to the base temperature T B AS, from the sum of which the actual temperature T A CT of the glow plug 2 results.
- This actual temperature T A CT is now used in the control cycle, where it is in the
- Block 20 is subtracted from the temperature setpoint T DE s.
- the difference between the temperature setpoint T DE s and the actual temperature T A CT is fed to a controller 21, which determines a voltage U G ov, which is the glow plug 2, in particular the heater of the glow plug 2, for rapid adjustment of the temperature setpoint T DE s supplied ,
- FIG. 3 shows two temperature-time diagrams in which the measured temperature Tm is shown once without predictive modeling (FIG. 3a) and once with predictive modeling (FIG. 3b). It can be seen from FIG. 3a that the measured temperature Tm, which is to be adapted to the temperature setpoint T Des , has a temperature overshoot shortly after the start of the annealing process, which does not approach the temperature setpoint T Des until after a time of approximately 30 seconds. For comparison, the temperature Tmo modeled mathematically according to FIG. 2 without model 8 is shown, which after the preheating phase, approximately after 5 seconds, corresponds to the level of the Tm
- Temperature setpoint T Des is reached and regulated by this.
- FIG. 3 b shows the course of the measured temperature T m when taking into account the resistance difference A R determined in advance by means of the predictive temperature model 8.
- Tm shows no temperature overshoot, but approaches immediately after the Preheating phase of the modeled temperature Tm.
- the temperature setpoint T Des is reached by means of this control and is regulated by this. Due to the predictive model 8, it is possible that a temperature control of the glow plug 2 not only during stationary operation, in which no more resistance-temperature fluctuations, but also in transient operation, preferably in the rapid preheating at the beginning of the annealing process and during to carry out the heating phase.
- Preheat phase is modeled, how large will be the resistance difference ER at the end of the preheating process, this difference in resistance ER is fed as an input to the control process.
