Definitions
- the invention relates to a device and a method for correcting the injection behavior of at least one injector with a device for storing information about the at least one injector and means for controlling the at least one injector taking into account the stored information, the information being obtained by comparing of desired values with actual values can be determined individually at a plurality of test points of the at least one injector and are referenced.
- a generic device and a method for correcting the injection behavior of at least one injector, in which the information is correction quantities for a quantity correction field of the injector, are disclosed in DE 102 15 610 A1.
- the control duration is corrected in a control device individually for each injector as a function of setpoint and rail pressure compared to a nominal characteristic map 210 (see FIG. so as to come as close as possible to a desired setpoint.
- four test values from the production for example the injection quantity at four different test points, are stored in the control unit during installation per injector, for example. From these quantities, a cor- rectification quantity map 220 (see FIG.
- this map is a quantity error map.
- a corrected quantity requirement is then calculated for a desired injection quantity with the quantity error characteristic field given a rail pressure.
- a drive time is then determined with the inverted nominal characteristic map 210 of the injector.
- An example of such a quantity correction at one of the test points will be described with reference to FIG. 3, whereby in this case the assumption is made of error-free measurements.
- an amount q P, lst which differs by ⁇ q from the nominal quantity qp jSO n , is measured for the activation duration t P.
- Such devices and methods are used in particular for electrically operated injectors for injecting diesel fuel, for example in the context of so-called common rail systems.
- common rail pressure generation and injection are decoupled.
- the injection pressure is generated independently of the engine speed and the injection quantity and is ready for injection in the so-called “rail”.
- the injection time and the injection quantity are calculated in the electronic engine control unit and converted by an injector on each engine cylinder via a remote-controlled valve.
- the invention offers the advantage of making the injector-specific quantity equalization directly on the level of the activation duration.
- the precision of the injected fuel quantities is substantially increased.
- it is not necessary to assume a constant characteristic gradient in the vicinity of the test points, as is the case with the previously described method known from the prior art.
- neither a coincidence of the slope of the nominal and the real characteristic nor of a known form of the course of injection must be assumed.
- the transmission of the control duration correction determined for individual test points to the entire pressure setpoint characteristic map is easier than for a quantity error characteristic map. This considerably improves the accuracy of the individual quantity comparison and extends the applicability of the method to larger problem classes.
- the means for controlling the injectors are preferably integrated in an engine control unit.
- the injector-specific control with the associated correction is performed by the engine control unit.
- the means for storing the information at the injector are for example a data memory attached to the injector, resistors arranged on the injector, barcodes arranged on the injector or, for example, a labeling field, also an alphanumeric encryption which is detected by a camera is possible.
- a preferred embodiment provides, as a device for storing information, a semiconductor integrated circuit arranged on the injector.
- a semiconductor integrated circuit can be integrated, for example, in the head of the injector.
- the data used by the controller is preferably stored in the semiconductor integrated circuit in a nonvolatile memory.
- the engine control unit also preferably has a semiconductor integrated circuit with which the information stored in integrated semiconductor circuits of the injectors is processed so as to achieve injector-specific control.
- Figure 1 is a schematic representation of part of a be ⁇ known from the prior art common rail system.
- FIG. 2 shows the correction over the quantity error according to a method known from the prior art
- Fig. 3 shows schematically the effect of a slope deviation in the known from the prior art correction over the quantity error at a test point
- FIG. 5 schematically shows the determination of a characteristic curve section and the corrected actuation duration according to the method according to the invention.
- Fig. 1 the high pressure part of the known from the prior art Speicherein ⁇ injection system common rail is shown.
- the arrangement comprises a high pressure pump 10, which communicates via a high pressure line 12 with the high pressure accumulator ("rail") 14 in connection.
- the high pressure accumulator 14 is connected via further high pressure lines to the injectors.
- a high-pressure line 16 and an injector 18 are shown.
- the injector 18 is part of an engine of a motor vehicle.
- the shown te system is controlled by an engine control unit 20. In particular, control of the injector 18 takes place by the engine control unit 20.
- a device 22 for storing information which relates individually to the injector 18.
- the information stored in the device 22 can be taken into account by the engine control unit 20, so that individual control of each injector 18 can take place.
- the information can be correction values for the quantity profile of the injector 18, which are determined in the manner described above in connection with FIGS. 2 and 3.
- the device 22 for storing the information can be implemented as a data memory, as one or more electrical resistors, as a barcode, by alphanumeric encryption or else by a semiconductor integrated circuit arranged on or in the injector 18.
- the engine control unit 20 can also have a semiconductor integrated circuit for evaluating the information stored in the device 22.
- a section of the characteristic curves "quantity over actuation period" is measured for several test points.
- the procedure is as follows.
- For the purpose of smoothing the stroke-to-stroke scattering at a test point a certain number, for example 50, of directly consecutive injections with different actuation durations are carried out in an area to be determined suitably (sweep). Since these quantities - as mentioned - are subject to a stroke-to-hub scattering, a smoothing regression curve is laid by the data points, which now represents a section of the injector for the given rail pressure, as shown schematically in Fig. 4.
- the activation time correction can be used for the respective control point t p - t be determined corr which is required to achieve the target injection amount qp JSO n. In this way, apart from measurement errors, an exact quantity correction is possible in principle at the test point. Optionally, an extrapolation of the characteristic section can also take place in this step.
- the number and selection of the test points to be measured in this way must be determined with regard to the required precision of the actuation duration correction and other boundary conditions. The range over which the actuation duration is changed in the measurements depends on the maximum expected actuation duration correction per test point.
- the information about the actuation duration correction at various test points of the injector 18 is used in order to calculate a drive duration correction over the entire setpoint rail pressure range.
- a drive duration correction ⁇ t is determined in the above-described manner in a circuit unit 420. The sum of the two values t nOm and ⁇ t results in the activation duration tkorr-
