Definitions
- the present invention relates to a method for determining a control parameter for a fuel injector of an internal combustion engine, in which at least one of the Kraftstoffinj ektor applied fuel pressure value is detected, and in which a drive parameter for the fuel injector is determined taking into account the detected fuel pressure value.
- the invention also relates to a device for determining a control parameter for a fuel injector of an internal combustion engine, comprising a measuring device with which at least one fuel pressure value applied to the fuel injector can be detected, and an evaluation device with which a control parameter takes into account the detected fuel pressure value can be determined for the fuel injector.
- the term fuel injector is intended in the present context to include all types of control elements that are used to allocate the requested fuel mass into the cylinders (injectors, injection valves, etc.). Usually these are electrically controlled actuators. In addition to single injections, multiple injections are used in all combustion processes, in particular in engines operated with direct fuel injection, ie more than once is injected per working cycle.
- the conversion of the fuel mass to be allocated into a particular electrical drive signal of the fuel injectors is dependent on the pressure applied to the fuel injector fuel pressure.
- This fuel pressure is therefore measured, possibly filtered, and thus used to operate a model which, depending on the detected fuel pressure, calculates a drive parameter corresponding to the desired injection quantity, for example the injection time. For the duration of this injection time fuel is then injected by the fuel injector.
- IO-SW real-time software
- application software For example, the injection time and the start or end point of the injections are continuously calculated by the application software and transferred to the IO-SW.
- the real-time software gets the data in the fixed time and / or event grid from the application software and executes it by implementing the specifications autonomously.
- a corresponding problem occurs when, after a successful injection, the injection quantity or injection time of the first injection is controlled in order to correct, if necessary with a second injection, an incorrect quantity injection in the first injection. If the applied fuel pressure has changed between the first injection and the time of the control calculation of the associated injection quantity or time, the control calculation may come to the conclusion that a wrong quantity was injected during the first injection although this is not actually the case Case was. A subsequent corrective injection thus does not lead to an improvement, but a deterioration of the injection result.
- the invention is therefore based on the object to provide a method and an apparatus of the type mentioned, with which a drive parameter for a fuel injector of a fuel machine in a more accurate manner even with changes in the applied fuel pressure is possible.
- the evaluation device can be closed, taking into account the time of the fuel pressure value detection and / or the crankshaft angle position of the internal combustion engine in the fuel pressure value detection on the fuel pressure applied to the injection at the fuel injector, and that with Evaluation of the control parameters based on the fuel pressure can be determined, was closed on.
- the device according to the invention can have a device for taking into account the time of fuel pressure value detection and / or the crankshaft angle position of the internal combustion engine in the fuel pressure value detection and a device for closing the fuel pressure applied to the fuel injector during the injection.
- the invention thus provides for the calculation of the respective control parameter taking into account when or at which angle of the crankshaft of the internal combustion engine the fuel pressure value detection has taken place. Based on this information, the fuel pressure applied to the fuel injector during injection is closed. So there is a fuel pressure allocation to the injection event instead.
- the control parameter is in particular a parameter influencing the amount of fuel allocated in the combustion chamber of the internal combustion engine.
- the determination of the drive parameter is thus optimized by means of a position or time reference of the pressure detection value.
- the information about the fuel pressure which is likely to be present at the time of injection can then be used in pressure models, which on this basis determine the fuel injector driving parameters corresponding to a desired quantity of fuel to be dispensed.
- a reference can be established between the time or the position, ie the crankshaft angle, in the pressure measurement and the time or position in the calculation of the control parameter and / or the injection. For example, if it is known that a certain temporal pressure gradient exists, it can be determined by the time interval of the fuel pressure detection to be performed Injection estimated at the time of injection fuel pressure can be estimated.
- the driving parameter for the fuel injector may be performed on the basis of the presumably applied fuel pressure at the time of injection.
- the result is a more accurate determination of the control parameter, in particular also with changes in the applied fuel pressure.
- Errors in the offset fuel quantity are therefore minimized by the more accurate pilot control according to the invention. This ensures lower lambda deviations, especially during dynamic processes such as transient processes of the system.
- the more accurate feedforward leads to smaller deviations from the nominal operating point, relieves the regulator and ensures that application tolerances, eg. As a temperature-induced ridge during high load, can be reduced.
- a more precise catalyst management is made possible so that the same exhaust emission requirements can be met with much cheaper catalysts than before.
- a plurality of fuel pressure values can be detected, which can then be taken into account in the manner according to the invention.
- a plurality of drive parameters for the fuel injector can also be determined.
- the detected fuel pressure is the pressure applied to the fuel injector. It may, for example, also be the pressure applied in a fuel rail of a common-rail injection system, which pressure is detected by means of a suitable pressure measurement. Other ways of detecting the fuel pressure are of course possible.
- the internal combustion engine may be any type of internal combustion engine which requires an injection of fuel, in particular gasoline engines or diesel engines of motor vehicles.
- fuel injector encompasses all types of actuating elements which are used for allocating a fuel mass into the cylinders of an internal combustion engine (injectors, injection valves, etc.), in particular electrically controlled actuating elements. Such adjusting elements are known per se to those skilled in the art.
- crankshaft angle reference values or points in time of the pressure detection and the times or crankshaft angle positions of the injection phase ie the calculated injection time, as well as the time or crankshaft angle position of the injection time computation, are therefore related and thus to the one acting during the injection Fuel pressure closed.
- the control parameter it can then be evaluated with the aid of the angular position or the time at which the fuel pressure of the injector of the relevant cylinder will be at the next injection.
- the drive parameter may be the injection time.
- it may also be other driving parameters.
- control parameters are known per se to the person skilled in the art, depending on the particular injector used.
- corresponding injection valves eg piezo valves
- corresponding injection valves may be the opening stroke of the fuel injector and / or the opening cross section of the fuel injector.
- electrically controlled injectors eg solenoid valves
- it may alternatively or additionally also be an electrical variable serving to control the fuel injector, for example the electric current level.
- the injection time with which the injector is controlled is of central importance for the injected fuel quantity of a fuel injector.
- Opening stroke in this context means, for example in an injection valve, the height of the valve needle from the needle seat when opening the injection hole of the valve.
- the opening cross-section of the injector correspondingly means the size of the injection hole (s) for injecting the fuel into the combustion chamber.
- the start and end time of the injection to be carried out is of essential importance for the injection result and can also be taken into account accordingly.
- Other control parameters are of course conceivable, for example, the speed when lifting a valve needle of an injection valve from the needle seat, etc.
- the drive parameter can be determined in particular for an injection taking place after the fuel pressure detection.
- the evaluation device of the device of the An Kunststoff- erparameter for a taking place after the fuel pressure detection injection be determinable.
- the time of the fuel pressure value detection and / or the crankshaft angle position of the internal combustion engine present in the fuel pressure value detection can be estimated.
- the device according to the invention can have an estimating device with which the time of the fuel pressure value detection and / or the crankshaft angle position of the internal combustion engine present in the fuel pressure value detection can be estimated.
- Such an embodiment is particularly advantageous when the fuel pressure acquisition takes place in a fixed time grid (eg fixed 10 ms grid / segment synchronous). It is therefore estimated in the determination of the drive parameter, when the fuel pressure was last detected (sampled), ie in particular at which crankshaft angle position or at what time.
- An advantage of this embodiment is that no additional pressure detection is necessary. Likewise, no additional time or crankshaft angle information has to be stored for a specific detected fuel pressure value. This saves memory and computational effort, so that the drive parameter can be calculated quickly and in a favorable manner.
- the time of the fuel pressure value detection and / or the crankshaft angle position of the internal combustion engine present during the fuel pressure value detection can be detected and stored.
- the device can for this purpose have a detection and storage device.
- the fuel pressure value during the detection is thus a time and / or angular position given, which is taken into account in the further course for the determination of the drive parameter.
- the time of fuel pressure value detection or the crankshaft angle position in the fuel pressure value detection can be taken into account in a particularly accurate manner.
- At least two fuel pressure values can be detected, taking into account the times of the at least two fuel pressure value detections and / or the crankshaft angle positions of the internal combustion engine in the case of the at least two fuel pressure value readings on the fuel pressure applied during the injection. Accordingly, it can be provided that at least two fuel pressure values can be detected with the measuring device of the device, wherein the evaluating device, taking into account the times of the at least two fuel pressure value and / or the crankshaft angle positions of the internal combustion engine at the at least two Kraftstoffbuchwerter desken on the applied during the injection fuel pressure can be closed.
- fuel pressures applied to the fuel injector are measured at at least two different times.
- the pressure measurement can take place, for example, in a fixed grid, in particular several times per one revolution of the crankshaft.
- B. four pressure measurements per crankshaft revolution are performed.
- the measured fuel pressure values can be related to each other, so that it is possible to conclude the fuel pressure present at the time of injection in a particularly accurate manner. It is possible in this way, for example, in a timely manner
- a particularly simple and accurate evaluation option when detecting at least two fuel pressure values is that the fuel pressure applied to the injection is closed by means of interpolation and / or extrapolation of the detected fuel pressure values.
- the evaluation device of the device can be provided to close by means of an interpolation and / or extrapolation of the detected fuel pressure values to the applied during injection fuel pressure. For example, upon detection of two fuel pressure values, a linear course of the fuel pressure gradient may be assumed, and based on this, the fuel pressure presumably applied at the time of injection may be determined. If more than two fuel pressure values are detected, the accuracy of the interpolation or extrapolation increases accordingly. Also, it is then possible to examine a variety of other courses of the pressure gradient in addition to a linear course and to close on this basis on the pressure applied to the injection fuel pressure.
- the evaluation device can be used to conclude the fuel pressure applied during the injection by assuming the detected fuel pressure value as the fuel pressure applied during the injection. It is in particular possible to request a fuel pressure detection at a specific crankshaft angle. The result of this pressure measurement can then be used directly to operate the corresponding models which calculate the activation parameter. This refinement is particularly advantageous when the detection of the fuel pressure value applied to the fuel injector takes place shortly before the determination of the actuation parameter.
- the fuel pressure value applied to the fuel injector may be detectable with the measuring device of the device shortly before the determination of the drive parameter.
- the injection to be determined also occurs at a short time interval from the detection of the fuel pressure, it can then be assumed that the applied fuel pressure has changed only insignificantly compared to the detected fuel pressure. In this case, it is thus possible to assume the detected fuel pressure as the fuel pressure also present during the injection.
- the approach to request a fuel pressure detection targeted just before an injection is particularly advantageous if a very accurate injection is required, such. B. HCCI or CAI combustion process.
- the activation parameter for an injection performed before the fuel pressure detection) and / or the quantity of fuel injected at an injection performed before the fuel pressure detection can be determined.
- the activation parameter for an injection performed before the fuel pressure detection and / or the quantity of fuel injected at a fuel injection prior to the fuel pressure detection can be determined. According to the invention, therefore, both future injection events and injection events that have already taken place can be calculated in a precise manner. Accordingly, even with a specific request for fuel pressure detection, this can be carried out shortly after an injection has already taken place.
- an error detected in the determination is corrected by a second injection.
- the device according to the invention can be designed accordingly.
- an error detected in the correction calculation is reported to other components of the internal combustion engine. This is particularly advantageous if the error in the injection can not be corrected, for example, too much fuel was injected.
- the injection error can be passed to a lambda controller, so that this the
- the device may in particular be adapted to carry out the method steps of the patent claims.
- the time (time) is plotted on the x-axis.
- three different cases of the determination of a drive parameter are schematically shown one above the other (Case 1, Case 2, Case 3). In the example shown, these are in each case calculations of the injection time, with which a fuel injector is controlled. Of course, additionally or alternatively, other control parameters can also be calculated.
- the three cases Case 1, Case 2 and Case 3 are delimited by horizontal dividing lines Cl, C2 and C3 for clarity, with Case 1 above dividing line Cl, Case 2 between the dividing lines Cl and C2, and Case 3 between the dividing lines C2 and C3 is shown.
- a fuel pressure FUP rising linearly with time is applied to the fuel injector. This is shown in the diagram below the dividing line C3.
- the fuel pressure values FUP_1, FUP_2, FUP_3, FUP_4, etc. applied to the fuel injector are detected by means of a measuring device not shown in detail in a fixed time grid, in the example shown at intervals of 10 ms. At regular intervals, taking into account the detected fuel pressure values FUP_1, FUP_2, FUP_3, FUP_4, a calculation of the injection time for the fuel injector takes place by means of an evaluation device, not shown, of the device. The calculations are shown in FIG.
- TI_Calculation A designate and take place at the times TI_A, TI_B, TI_C, TI_D, TI_E, TI_F, TI_G, TI_H.
- the injection time calculation takes place in a segment-synchronous manner, that is to say in the case of a six-cylinder engine, in each case after 120 ° rotation angle of the crankshaft.
- the segment time in the example shown is 5 ms.
- the injection time calculation and the pressure acquisition are autarkic.
- the combustion process in the illustrated example uses double injection, i. H. per cycle two injections Il and 12 are discontinued at different times. In each case, the injection times for both injections are calculated for each calculation of the injection time. False amounts of the first pulse can be corrected with the second injection pulse. It can be corrected by appropriate adjustment of the second injection both a shortfall and too much offset fuel quantity.
- there is an ignition of the injected fuel as illustrated in the figure by the arrow IG.
- the injection times of the two injections II, 12 are calculated as part of the injection time calculation TI_Calculation B on the basis of the previously detected fuel pressure FUP_1 applied to the fuel injector.
- the injection II is then carried out.
- TI Calculation C the injection times for both injections are recalculated in TI Calculation C.
- TI Calculation C is again based on the previously recorded fuel pressure value FUP 1. Consequently is changed in the calculation TI Calculation C at the injection time for the injection 12 nothing. In fact, however, the pressure FUP has meanwhile increased considerably compared with the first detected pressure FUP_1. It is thus injected at 12 significantly too much fuel. This is not detected in the injection time calculation TI_Calculation C. If the ignition IG takes place at a later time, the performance of the internal combustion engine is undesirably impaired.
- Case 2 shows an example that differs from Case 1 in that only one injection per cycle is performed. This injection is designated in Case 2 with II '.
- the injection time for the injection II ' is calculated at the time TI_E on the basis of the last-detected fuel pressure value FUP 2 at TI_Calculation E. Since the injection II ', however, takes place considerably later than the detection of the fuel pressure FUP_2, the fuel pressure FUP at the time of the injection II' is significantly higher than the previously detected fuel pressure FUP 2. Consequently, in this example, an excessively large fuel quantity is caused by the fuel Fuel injector discontinued. In the case of the ignition of the fuel, which is illustrated by the arrow IG ', there are again undesirable effects on the operation of the internal combustion engine.
- a second embodiment of the invention is shown, which is particularly at very high requirements on the injection accuracy, such as. can be used in HCCI or CAI combustion process.
- the injection time for a subsequent injection H "and an associated crankshaft angle are calculated in the context of the calculation TI_Calculation E.
- the last detected fuel pressure FUP_2 is taken into account.
