Definitions
- the invention relates to a method for detecting a change of glow plugs in an internal combustion engine, wherein during a Fahrzyklusses at least one electrical parameter of the glow plug is determined, which is compared with a stored value of the same electrical parameter of the glow plug, which was determined in a previous drive cycle , And a device for carrying out the method.
- a method and a device for detecting the change of glow plugs in an internal combustion engine are known in which at the beginning of a Fahrzyklusses at least one electrical characteristic measured at least one glow plug, determines a current value of this parameter and at least one stored value of the same electrical characteristic of this glow plug is compared, which was determined at the beginning of at least one previous driving cycle and in which when the deviation of the current value of the stored value exceeds a predetermined threshold value is detected on a candle change.
- current, resistance and / or electrical performance curves or individual defined values are used by comparing these courses and / or values from the current and the preceding driving cycle.
- the invention is therefore based on the object to provide a method and apparatus for detecting a change of glow plugs in an internal combustion engine, which allows independent of the environmental conditions, an accurate detection of the change of the glow plug.
- the object is achieved in that in the drive cycle, the same electrical parameter is determined in all internal combustion engine glow plugs, these electrical parameters of the glow plugs behave in a certain pattern to each other and this pattern of the electrical parameter of the glow plugs is compared with a pattern, which was determined in a preceding driving cycle, wherein a deviation of the pattern of the driving cycle from a pattern of the preceding driving cycle is detected on a change of a glow plug.
- This continuity in the electrical parameters is evaluated to detect the change of the glow plugs. This has the advantage that a significant improvement in the robustness of detecting the change of the glow plugs is achieved.
- the pattern of the glow plugs is determined by the magnitudes of the electrical parameter measured at the various glow plugs. By considering the respective size ratio, which is maintained in each operating state, it is particularly easy to see which individual candle has been replaced.
- the at least one electrical parameter of all glow plugs is measured at approximately the same time. This ensures that the measurement of all glow plugs in the same operating condition of the internal combustion engine.
- the patterns of the electrical parameters of the glow plugs are stored over driving cycles and recognized from the discontinuity of the pattern with the stored pattern on a candle change.
- current deviations are comparable to a history, whereby a natural aging curve of the glow plugs can be hidden.
- the electrical parameter is a current and / or a resistance and / or a power of the glow plug.
- the Wderstand is a cold resistance, a hot resistance and / or a change in resistance.
- changing these values provides a sure indication of a candle change.
- these values are relatively easy to measure and are usually already recorded in a glow plug control.
- the invention relates to a device for detecting the change of glow plugs in an internal combustion engine with a measuring unit for measuring at least one electrical parameter of a glow plug and a memory unit for storing the at least one electrical parameter of a glow plug.
- the measuring unit measures at least one electrical parameter see all, built in the engine glow plugs and the
- the memory unit stores the measured values of the at least one electrical parameter of all the glow plugs, and a pattern detection unit connected to the measurement unit and the memory unit determines the pattern formed by the at least one electrical parameter of all the glow plugs and compares this with the stored values of the at least one a parameter of the glow plugs resulting pattern and when the pattern of the measured values deviates from the pattern of the stored values, it recognizes a change of a glow plug.
- the evaluation of the sample has the advantage that when a glow plug, compared to another glow plug, a lower power and hoetz- would take, for example at idle, even under full load, a lower power and
- Figure 1 Schematic representation of an annealing system in a motor vehicle.
- a start-up aid for ignition of the fuel-air mixture introduced in the internal combustion engine at ambient temperatures of ⁇ 40 ° C.
- glow systems which consists of glow plugs, a glow time control unit and an annealing software, which is stored in an engine control unit or the Glühzeit Kunststoff Kunststoff consists.
- annealing systems are also improving the emission of the vehicle used. Further fields of application of the glow system are the burner exhaust system, the auxiliary heating, the preheating of fuel or the preheating of the cooling water.
- FIG. 1 shows such an annealing system in which several glow plugs 2 to
- each glow plug 21 to 24 protrudes into a respective cylinder of a combustion chamber of the internal combustion engine, not shown.
- the glow plugs 21 to 24 are identically constructed and represent conventional low-voltage glow plugs. In Figure 1, the glow plugs 21 to 24 are shown for simplicity as a substitute resistance, which lead to the mass 3 of the engine.
- the glow plugs 21 to 24 are connected to a glow time control unit 4, which has a power semiconductor 51 to 54 for each glow plug 21 to 24.
- the glow time control device 4 comprises a microcontroller 4a for processing incoming and outgoing signals. Alternatively, instead of the microcontroller 4a, an ASIC can also be used.
- a vehicle electrical system voltage 6 is connected to the Glühzeit Kunststoff réelle 4, which supplies the glow plugs 21 to 24 via the power semiconductors 51 to 54 with the required effective voltage.
- the Glühzeit tenu réelle 4 leads to an engine control unit 7, which in turn is connected to the internal combustion engine, not shown.
- the engine control unit 7 and the glow time control unit 4 have an interface. This interface can consist of both a single-wire and a two-wire connection 10, 11 (FIG.
- the glow time control unit 4 outputs via the power semiconductors 51 to 54 to the glow plugs 21 to 24 a pulsbrei- modulated output signal, which adjusts the required Glühmannkerzen Kunststoffschreib at the respective glow plugs 21 to 24.
- the glow time control device 4 comprises a measuring unit 12, a memory unit 13 and a pattern recognition unit 14.
- the measured by the measuring unit 12 electrical current values of all glow plugs 21 to 24 are stored in the storage unit 13.
- another signal is also output at the beginning of the driving cycle, so that the measuring unit 12 in turn measures the current values of the glow plugs 21 to 24. This can be done at full load this time.
- the environmental conditions of the motor vehicle play no further role in this type of measurement.
- Values of the current values of all the glow plugs 21 to 24 recorded in the first driving cycle are then compared with all current values of the glow plugs 21 to 24 that were supplied by the measuring unit 12 in the second driving cycle by the pattern recognition unit 14.
- the current values show in their size ratios to each other a specific pattern, which is similar in idle as under full load. If no glow plug was replaced, the magnitudes of the individual current values of the glow plugs 21 to 24 are the same both for the stored values and for the values newly measured in the second cycle. If, however, these size ratios of the glow plugs 21 to 24 differ, it is assumed that a glow plug has been replaced.
- Patterning can further extend the limits of engine conditions and thresholds for detecting a candle change.
