Definitions
- the invention relates to an injection pump unit, consisting of from an injection pump with a control rod adjusted by an actuator and its position by one Position sensor is detected, and from a control unit, which calculates an injection quantity, from this on the basis of stored Characteristic values a target position signal for the quantity-determining link determined and in a position controller by comparing the target position signal with a Actual position signal of the position sensor is a control signal generated for the actuator, with the control path limiting Stops are provided which interact with counter surfaces, at least one of which is arranged such that the corresponding stop outside of the dynamic Adjustment range of the injection quantity touched.
- the saved Characteristic values give the allocation of injection quantity and path of the control rod depending on engine parameters (for example, the speed of the engine) usually, but not necessarily as a map.
- From DE-PS 38 30 534 is a method for readjustment a series of actuated by a common operating rod Pump nozzles known to correct the measurement error the position sensor known two fixed stops Distance and the measured values corresponding to these used to correct the following measurements.
- the position controller to form the Control variable for the control rod determined from the map Target paths always with corrected, i.e. correct, Actual values of the path of the control rod are compared.
- the map itself based on which from the target injection quantity The target control rod path is calculated, remains entirely untouched.
- the accuracy of the given setpoint of the position of the quantity-determining link depends on the agreement the map of the injection pump with its actual Delivery behavior, not only from the speed, but also from the back pressure, i.e. from the fuel lines and the resistance in the nozzle, which too scatters, is dependent. Especially with injection pumps for very high injection pressures the influence of the resistance is and the leakage amounts very large and annoying, above all with additional control of the injection rate by temporarily Reduction of injection cross sections.
- stops are adjustable, and that fixed in the control unit Distances are stored, the counter surfaces at one determined measured injection quantity to corresponding opposite Have attacks.
- the two stops are not simply used for calibration of the position signal, its effect goes far beyond that.
- both stops so that they each have the position of the quantity-determining link at one with the associated speed exactly - so already on the pump test bench - correspond to the measured injection quantity (correspond, because the paths around the certain, constant Distances from these), is location and Slope of the individual pump characteristic fully taken into account; that is, through the stops so set the path of the control rod between the two stops of the pump different from pump. That is the individual attitude the pump unit very quickly before installing it and carried out exactly.
- the control unit can move the control rod at any time the right one for each specified target injection quantity Target position of the control rod and for each signal from the position sensor determine the actual injection quantity.
- the determined distance between the stops and the appropriate trained counter surfaces ensures that the Movement of the control rod during operation through the stops is not hindered.
- the control rod must, for example when returning from full load to idle for dynamic reasons below that assigned to idle Can move the injection quantity. It also ensures that the motor is about when the position sensor is short-circuited turns itself off.
- the one constant distance is previously determined so that the control rod is in a Position for zero funding is when the stops touched.
- the value of the fixed distances can thus can be selected for an entire pump type. That makes it easier replacing a pump unit because it does is possible without intervention in their control.
- the certain distance in the setting is easiest by a caliber (one between the stop and the counter surface imported gauge body with the thickness k) fixed; but it could also be by means of a suitable electronic and / or optical device are observed.
- the determined measured injection quantities are in a first form the idle injection quantity and the maximum Injection quantity (claim 4), in a second it is Injection volumes at two separate part load points (Claim 5).
- the latter is particularly curved To give preference to the characteristic curves, because in this way the Deviations in the middle part-load range can be minimized.
- an according to the invention is particularly advantageous designed injection unit in the context of a pump nozzle, each with its own control rod. (Claim 7). Since the pump nozzle already during calibration is composed, the scatter of the Throttle losses are taken into account precisely. So that goes on ensures that each individual cylinder has optimal emissions operated will also deliver its maximum output can. The same applies in the case of plug-in pumps.
- the invention is also about a method of adjustment an injection pump unit according to the invention, which in is exercised in two ways. First of all for setting at 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, about every time the engine is started to during the lifetime to compensate for changes that occur, or to after replacing the injection pump unit, the injection pump, the control unit or the sensor carry out automatic calibration.
- First of all for setting at 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, about every time the engine is started to during the lifetime to compensate for changes that occur, or to after replacing the injection pump unit, the injection pump, the control unit or the sensor carry out automatic calibration.
- one receives one fully calibrated complete injection pump unit the thanks to the automatic assignment without further settings can be installed in the engine, be it in a new building it as a spare part. This is also the case with a pump nozzle Fine adjustment to the throttling losses of the individual nozzle performed. The workload required for this is limited adjusting the injection quantity on Test bench and the adjustment of the two stops. Of the Command to automatically move to the stops is part of the control program, which is stored in the memory of the control unit is.
- the injection pump unit shown in Figure 1 exists from an injection pump 1 and a control unit 2.
- the injection pump 1 becomes a pump piston 3, for example up from a camshaft 4 via a rocker arm 5 moved.
- the pump piston 3 is by means of a control rod 6, in the example shown it is a in sliding control rod, rotated, whereby by the shape of the in the pump body 7 or on the pump piston 3 arranged control surfaces 8 in a known manner, the injection quantity is adjusted.
- Injection pump is a pump nozzle that Invention is in the same way but also on an arrangement with injection pump spatially separated from the injection nozzles applicable.
- the control rod 6 is moved by an actuator 13 which is symbolized by a solenoid coil 14. Furthermore a position sensor 15 is provided, which the control unit 2 a signal ⁇ (arbitrary Dimension, e.g. Voltage, capacitance or frequency).
- the control unit 2 also receives a load request signal 16, such as from the accelerator pedal of the vehicle, an engine speed signal 17 and various other signals 18 used for the determination of the injection quantity, such as air pressure and temperature.
- the injection pump 1 is only in plan view pictured.
- the upper part of the pump piston can be seen 3, the displacement of the control rod 6 for adjustment the injection quantity is rotated.
- the pump housing 20 are two stops 21.22 arranged adjustable with Interact with counter surfaces 23, 24 on control rod 6.
- the Stops 21, 22 are preferably provided with threads, so that it is precisely adjusted and then secured against twisting can be what is not shown in detail.
- Ml idle flow rate
- the control rod 6 which is approximately the full-load injection quantity M2 is between the stop 22 and the counter surface 24 'a distance k2 (26). This is stated in the functional description come back.
- the control unit 2 consists of a computer 30, a required injection quantity from load demand signal 16, engine speed signal 17 and the other signals 18 to M calculated, and a control section 31 for the individual injection pump. In the case of individually controllable injection pumps (pump nozzles), there are further such control parts 31 '.
- 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 controlled accordingly via a line 37.
- 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 M 1 and the path ⁇ 1 of the control rod
- 42 is the full load point, corresponding to the full load injection quantity M 2 and the path ⁇ 2 of the control rod.
- Figures 3 and 4 each show an individual Characteristic curve of an injection pump unit of the same type. The differences in position and slope of the two curves 40 are recognizable, they result from production-related Scattering.
- 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 element hereinafter referred to as control rod
- the stop 21 is set while the control rod is held (double arrow 50) until the distance between it and the counter surface 23 has the previously generally determined and stored in the memory at 38 size k 1 , which is selected such that the delivery rate when the stop is approached directly 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 k 2 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 emitted position signal ⁇ 0 is stored . Then the stop 22 is approached directly up to the point of contact and the emitted position signal ⁇ 3 is also stored.
- the predetermined distances k 1 and k 2 are already or are also stored. This completes the pump unit setting. The predetermined distances k 1 and k 2 are most easily set using a distance gauge.
- the curve 40 is thus corrected and the injected quantities M 1 , M 2 again correspond to a corrected control rod position ⁇ 1 ', ⁇ 2 '.
- the intermediate values are then obtained again during operation by linear interpolation.
- An injection quantity M will then corresponds to a load point 43 on the curve 40, from this is derived by interpolation, as indicated by box 44, a ⁇ to be formed, which can be directly transferred to the position controller 35th 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 (less far) Partial load points separated from each other can be defined. 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 Value M o , which is zero funding, has reached. 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.
