Definitions
- the invention relates to an injection pump unit, consisting of an injection pump, in which a control rod is adjusted by an actuator and the position of which is detected by a position sensor, and a control unit that calculates an injection quantity, from which a target is calculated based on stored characteristic values Position signal for the quantity-determining element is determined and a control signal for the actuator is generated in a position controller by comparing the desired position signal with an actual position signal of the position sensor, with stops limiting the path of the control rod being provided.
- the stored characteristic values generally, but not necessarily, provide the assignment of the injection quantity and displacement of the control rod as a function of engine characteristics (for example the speed of the engine) as a map.
- DE-OS 30 11 595 discloses a correction device for a fuel metering system with drift compensation, in which the relationship between the injection quantity and the position of the control rod is corrected at an operating point in such a way that the signal is equal to that at this point originally owned target signal.
- the original feedback signal is set to a specific injection quantity.
- the assignment is adjusted during the speed-controlled operation at idling point until the position controller has reached the value corresponding to the respective operating point, for which purpose an additional adjustment device is needed. This method is time-consuming and requires either a complicated encoder or the connection of an additional error signal.
- the accuracy of the predetermined setpoint of the position of the quantity-determining member depends on the agreement of the characteristic diagram of the injection pump with its actual delivery behavior, which is not only dependent on the speed, but also on the back pressure, ie on the fuel lines and is dependent on the resistance in the nozzle, which also scatters.
- the influence of the resistance and the leakage quantities is very large and disruptive, especially when the injection rate is additionally controlled by temporarily reducing the injection cross sections.
- each pump is measured before installation, a stop is set and a uniform correction value is used.
- This correction value takes into account the position, but not the slope of the respective pump characteristic.
- the individual pumps are therefore still within a wide tolerance range that cannot be taken into account.
- the selected correction values are no longer correct, which leads to problems.
- stops are adjustable and that fixed distances are stored in the control unit, the counter surfaces having a certain measured injection quantity to corresponding opposite stops, at least one of the counter surfaces being arranged in such a way that that it touches the corresponding stop outside the dynamic adjustment range of the injection quantity.
- the two stops do not simply serve for the calibration of the position signal, their effect goes far beyond that.
- both stops are set so that they correspond to the position of the quantity-determining member at an injection quantity measured precisely at the associated speed - that is, already on the pump test bench - because the paths vary by the determined, constant distances therefrom distinguish), the position and slope of the individual pump characteristic is fully taken into account; This means that the stops of the control rod between the two stops differ from pump to pump due to the stops set in this way.
- the individual setting of the pump unit is carried out very quickly and precisely even before it is installed.
- the control unit can determine the correct target position of the control rod and for each signal of the position sensor at any given target injection quantity determine the actual injection quantity.
- the certain distance between the stops and the suitably designed counter surfaces ensures that the movement of the control rod during operation is not hindered by the stops.
- the control rod must, for example, be able to move below the injection quantity associated with the idle when dynamically returning from full load to idling. In addition, this ensures that the motor switches itself off when the position sensor is short-circuited.
- the one constant distance is previously determined so that the control rod is in a position for zero delivery when it touches the stop.
- the value of the fixed distances can therefore be chosen to be the same for an entire pump type. This facilitates the replacement of a pump unit because it is possible without intervention in its control.
- the assignment between the control and the injection pump takes place automatically when the stops are first routinely scanned.
- the determined measured injection quantities are the idle injection quantity and the maximum injection quantity (claim 4), in a second it is the injection quantities in two part load points that are distant from one another (claim 5).
- the latter should be given preference in the case of particularly strongly curved characteristic curves, since this minimizes the deviations in the middle part-load range.
- the characteristic diagram adapted to an individual injection pump can be replaced by a theoretically determined characteristic curve (claim 6). Since the design and use of the stops in accordance with the invention makes it possible to stretch or compress and twist the characteristic diagram, individual differences can be compensated in this way by calibration. This makes calibration and adjustment particularly easy while maintaining the greatest possible accuracy.
- the invention also relates to a method for setting an injection pump unit according to the invention, which is carried out in two ways. First to adjust during assembly with subsequent automatic calibration (also called mapping) when combining the injection pump and sensor with the control unit, for example when installing the unit, and subsequently for regular readjustment, for example each time the engine is started, to during to compensate for changes in the service life, or to carry out an automatic calibration after replacing the injection pump unit, the injection pump, the control unit or the sensor.
- subsequent automatic calibration also called mapping
- the command to automatically approach the stops is part of the control program which is stored in the memory of the control unit.
- Such a calibrated pump unit is then readjusted again and again in the vehicle due to the programmed command by moving to the stops (claim 9), in order to compensate for changes in the position sensor (aging, drift), thereby making the pump unit self-adjusting. Since such changes take place slowly adjustment is not necessary every time you start.
- Fig.2 The same pump unit as in Fig.l in plan view, designed according to the invention
- Fig. 3 A characteristic curve from the characteristic diagram of an individual pump
- Fig. 4 A characteristic curve from the characteristic map of a similar but different individual pump during calibration before installation.
- the injection pump unit shown in FIG. 1 consists of an injection pump 1 and a control unit 2.
- a pump piston 3 is moved up and down, for example from a camshaft 4, via a rocker arm 5.
- the pump piston 3 is set in rotation by means of a control rod 6, in the example shown it is a control rod which is displaceable in itself, the injection quantity being adjusted in a known manner by the shape of the control surfaces 8 arranged in the pump body 7 or on the pump piston 3 .
- an injection nozzle 9 immediately adjoins the pump body 7; the throttle points which influence the course of the injection are designated by 10.
- the injection pump shown is a pump nozzle, but the invention can also be applied in the same way to an arrangement with an injection pump that is spatially separated from the injection nozzles.
- the control rod 6 is moved by an actuator 13, which is symbolized by a solenoid coil 14.
- a position sensor 15 is provided, which supplies the control unit 2 with a signal ⁇ (of any dimension, for example voltage, capacitance or frequency) describing the actuating path.
- the control unit 2 also receives a load request signal 16, for example from the accelerator pedal of the vehicle, an engine speed signal 17 and various other signals 18 which are required to determine the injection quantity, such as air pressure and temperature.
- the injection pump 1 is only shown in plan view.
- the upper part of the pump piston 3 can be seen, which is rotated by moving the control rod 6 to adjust the injection quantity.
- two stops 21, 22 are adjustably arranged, which interact with counter surfaces 23, 24 on the control rod 6.
- the stops 21, 22 are preferably provided with threads so that they can be adjusted precisely and then secured against rotation, which is not shown in detail.
- k2 In the position 6 'of the control rod 6 shown in broken lines, which corresponds approximately to the full-load injection quantity M2, there is a distance k2 (26) between the stop 22 and the counter surface 24'. This is dealt with in the functional description.
- the control unit 2 consists of a computer 30, the injection pump from load demand signal 16, engine speed signal 17 and the other signals 18, a required injection amount M S oll berech ⁇ net, and a control section 31 for the individual Ein ⁇ .
- a control section 31 for the individual Ein ⁇ In the case of individually controllable injection pumps (pump nozzles), there are further such control parts 31 '.
- the determined in the computer 30 Ein ⁇ required injection quantity M S oll is fed via line 32 to the unit 33 communicated to the control part 31, which, using a pump characteristic curve 40 (which can be a general or only expressed by a few points), determines a desired signal ⁇ soll for the path of the control rod 6 and communicates it to the position controller 35 via the line 34.
- the actual position signal coming from the position sensor 15 via the line 36 is compared with the desired position signal and the solenoid 14 is correspondingly controlled via a line 37.
- a memory which has access to the signal coming from the position sensor 15 and which is also connected to the unit 33 via the data line 39 in order to compare the pump characteristic curve 40 to the conditions determined when both stops were approached push and twist to assign them to the control.
- the memory contained in 38 transmits the command for moving to the stops to the position controller 35 via the line 46.
- the blocks 33, 35, 38 shown are not necessarily to be understood as separate functional units; they can also be program modules of a programmable logic controller.
- the control rod path ⁇ is entered on the ordinate and the injection quantity M on the abscissa.
- the pump characteristic curve which has two characteristic points 41, 42, is designated by 40. 41 is the idle point, corresponding to the idle injection quantity Mi and the path ⁇ i of the control rod, and 42 is the full load point, corresponding to the full load injection quantity M2 and the path ⁇ 2 of the control rod.
- FIGS. 3 and 4 each show an individual characteristic of an injection pump unit of the same type.
- the differences in position and slope of the two curves 40 can be seen, they result from production-related variations. These differences are recognized in the unit according to the invention and by the method according to the invention and fully compensated for. This is now described with reference to FIGS. 4 and 5:
- the individual pump is located on the pump test bench for calibration ( Figure 4).
- the idle point 41 is approached at idle speed.
- the quantity-determining member hereinafter referred to as the control rod
- the stop 21 is set (double arrow 50) until the distance between it and the counter surface 23 has the previously determined and stored value ki in the memory at 38, which is selected such that the delivery rate when the vehicle is started directly Stop is equal to or almost zero.
- the stop 21 is locked.
- the full load point 42 is approached at a speed suitable for the full load, the stop 22 is adjusted to the distance k2 and locked.
- the injection pump itself is now set in a purely mechanical way and is ready for installation.
- the stop 21 is first approached directly up to the point of contact and the dispensed one Position signal ßo ge stored. Then the stop 22 is approached directly up to the point of contact and the position signal ⁇ 3 emitted is also stored.
- the predetermined distances ki and k2 are already or are also saved. This completes the setting of the pump unit.
- the distances ki and k2 defined in advance are easiest to set using a distance gauge.
- the control unit can determine the sensor signals ßi and ß2 assigned to the injection quantities Mi and M2 and at any time for each injection quantity M So ll the correct target position signal ßsoll the control rod, or vice versa to determine the actual injection quantity for each sensor signal.
- the setting of the characteristic curve 40 in FIG. 33 has thus been made taking into account the position signal, which may have errors, so that a separate correction of the sensor signal ⁇ is unnecessary.
- the curve 40 is thus corrected and the injected quantities Mi, M2 correspond to a corrected control valve position ⁇ 1 ', ⁇ 2'.
- the intermediate values are then obtained again in operation by linear interpolation.
- a load point 43 on the characteristic curve 40 then corresponds to an injection quantity Msoll, from which an ßsoll is formed by interpolation, which is indicated by the box 44, that can be passed directly to the position controller 35. There it is compared with the signal ⁇ coming directly from the position sensor 15 and the control rod 6 is adjusted accordingly.
- the load points 41, 42 can also be defined as (less far) distant part load points. The linear interpolation then causes fewer deviations.
- the constants k 1, k 2 are set such that the stops 21, 22 are so far from the operating points 41, 42 (idling and full load) that the curve 40 there has the value Mo , that is zero funding. All in all, a system that is easy to calibrate and self-aligning is created, in which full safety and intrinsic safety is guaranteed in all cases.
