Definitions
- the invention relates to an apparatus 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 desired injection quantities be determined with actual injection quantities individually at several test points of the at least one injector and are based.
- the control duration in relation to a nominal characteristic map 210 (cf. Fig. 2 ) corrected so as to come as close as possible to a desired target amount.
- 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 variables, a correction quantity map 220 (see FIG Fig. 2 ) as a function of the desired amount and the fuel pressure.
- this map is a quantity error map.
- the controller is then given Rail pressure to a target injection quantity with the quantity error map calculated a corrected quantity requirement.
- 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 is based on Fig. 3 described, which is assumed to be error-free measurements.
- an amount q P is measured for the activation time t P , which deviates by ⁇ q from the nominal quantity q P, soll .
- a quantity requirement q P is to be reduced by ⁇ q to q mod , over the normal characteristic results from this a drive time t corr .
- the injection of the quantity q P is to be effected by the injector controlled with a control duration t corr . If, on the other hand, both characteristic curves do not run parallel, the resulting injection quantity q corr is not equal to the quantity requirement, although the injector was tested at the relevant point.
- a method for quantity correction due to pressure signals, with the aid of an injector drift can be corrected.
- the start of injection and the end of injection are compared with values of the injection start, preferably stored in an individual map of the injector and the end of injection of this operating point, corrected in a deviation of injection start and / or injection duration so that the deviation disappears and the correction values are stored.
- Such devices and methods are used in particular in electrically operated injectors for the injection of diesel fuel, for example in the context of so-called common rail systems for use.
- common rail accumulator injection
- 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 timing and the injection amount are calculated in the electronic engine control unit and implemented by an injector on each engine cylinder via a remote-controlled valve.
- the invention offers the advantage of making the injector-specific quantity adjustment directly on the level of the activation duration.
- the precision of the injected fuel quantities is significantly increased.
- it is not necessary to assume a constant characteristic gradient in the vicinity of the test points, as is the case with the above-described method known from the prior art.
- neither a coincidence of the slope of the nominal and the real characteristic nor a known form of the injection curve must be assumed.
- the transmission of the control duration correction determined for individual test points to the entire desired pressure quantity characteristic map is easier than for a quantity error characteristic map. This significantly improves the accuracy of the individual set balance and extends the applicability of the method to larger classes of problems.
- 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 alphanumeric encryption 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.
- Fig. 1 is the high pressure part of the known from the prior art storage injection system common rail 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 illustrated System is controlled by a motor controller 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 may be taken into account by the engine controller 20 so that individual control of each injector 18 may occur.
- the information can be correction values for the quantity map of the injector 18, which at the beginning in connection with FIGS. 2 and 3 be determined manner described.
- 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 may also comprise 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.
- a certain number, for example 50, of directly consecutive injections with different drive times are carried out in an area to be determined suitably (sweep). Since these quantities - as mentioned - are subject to a stroke-to-hub scattering, the data points a smoothing regression curve is placed, which now represents a section of the injector for the given rail pressure, as shown schematically in Fig. 4 is shown.
- 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 time is changed during the measurements depends on the maximum expected actuation duration correction per test point.
- the information about the measurement results of the control period correction must be recorded so that it is available later during installation of the injector 18 when installed in the engine, if necessary. This is done by the means 22 for storing the information.
- the information about the actuation period correction is used at various test points of the injector 18 in order to calculate a actuation duration correction over the entire setpoint rail pressure range. This happens as in the calculation of the quantity error map in the case of the prior art, for example the DE 102 15 610 A1 known and referred to as IMA method.
- IMA method the DE 102 15 610 A1 known and referred to as IMA method.
- the control unit is from setpoint and rail pressure by means of a nominal map 410 (see FIG. Fig. 5 ) determines the nominal actuation time t nom .
- 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 t corr .
