Definitions
- the invention relates to a method for controlling a Internal combustion engine with a common rail injection system according to the preamble of claim 1.
- a high-pressure pump delivers fuel from a fuel tank into a high-pressure accumulator.
- the high-pressure accumulator is called the high-pressure accumulator as a rail.
- the delivery flow of the high-pressure pump is controlled by a suction throttle certainly. Their position, in turn, is determined by an electronic one Control unit given as a function of input variables, z. B. the desired performance.
- the drive is the suction throttle as a PWM-modulated signal with a running constant frequency, z. B. 100 Hz.
- Conditional by this type of delivery of fuel is the rail consequently imprinted a periodic signal.
- the signal frequency corresponds the frequency of the PWM signal.
- the rail is periodically Taken from fuel, so that the periodically fluctuating High-pressure fuel is sampled. Is the fuel extraction z. B. with a frequency of 99 Hz, so arises Differential signal of 1 Hz. This means that the fuel high pressure a 1 Hz signal is superimposed.
- the invention is therefore the object of the pressure oscillations in the rail due to external excitation by the Reduce suction throttle.
- the invention provides that from the angular distance of two Injections, which defines the injection period, as well as the first frequency of the PWM signal (fundamental frequency) a critical Speed is calculated. Depending on the critical Speed is then set a speed range. At engine speed values within the speed range set the PWM signal to a second frequency. At engine speed values outside the speed range becomes the PWM signal set to the first frequency. In other words: The PWM signal is in the range of the critical speed of the first switched to the second frequency. For one increasing engine speed and for a falling engine speed each has its own speed range is provided. As well the invention provides that the frequency switching in the integer multiples of the critical speed becomes.
- the high-pressure control loop is stabilized.
- An additional optimization of high-pressure control parameters is not required.
- the P, I and D components of the high-pressure regulator remain unchanged.
- the effects on the hysteresis of the intake throttle are low, if the first and second frequencies differ only slightly, z. B. for the first frequency 100 Hz and for the second frequency 120 Hz.
- the time constants of the controlled system, d. H. the pumps with suction throttle and the rail in general are significantly larger than the reciprocal of the first and second frequency of the PWM signal, the switching takes place on the second frequency almost trouble-free.
- the effects on the high fuel pressure is therefore minimal.
- the invention offers the advantage that it is simple and little effort later in an electronic Control unit of an internal combustion engine can be applied.
- FIG. 1 shows an internal combustion engine 1.
- the fuel over a Injected common rail system.
- the operation of the internal combustion engine 1 is by a electronic control unit (EDC) 4 regulated.
- the electronic Control unit 4 contains the usual components of a Microcomputer system, for example a microprocessor, I / O blocks, buffers and memory blocks (EEPROM, RAM).
- I / O blocks I / O blocks
- buffers and memory blocks EEPROM, RAM
- EEPROM EEPROM
- RAM memory blocks
- the memory modules are for the operation of the internal combustion engine 1 relevant operating data in maps / characteristic curves applied. About this calculates the electronic Control unit 4 from the input variables, the output variables.
- the following input variables are exemplary represented: an actual rail pressure pCR (IST), which by means of a Rail pressure sensor 5 is measured, a speed signal nMOT the internal combustion engine 1, an input E and a signal FW for performance specification by the operator.
- Under the input E are, for example, the charge air pressure of a turbocharger and the temperatures of the coolants / lubricants and the Fuel subsumes.
- FIG 1 are as outputs of the electronic control unit 4 a signal ADV for controlling the suction throttle and a Output size A shown.
- the output size A is Representative of the other control signals to the controller and control of the internal combustion engine 1, for example the Injection start SB and the injection duration SD.
- the signal ADV is executed in practice as a pulse width modulated signal (PWM).
- PWM pulse width modulated signal
- FIG. 2 shows a high-pressure control circuit.
- the input quantity corresponds to the setpoint of the rail pressure pCR (SL).
- the output quantity corresponds to the raw value of the rail pressure pCR.
- From the raw value of the rail pressure pCR is filtered by means of a filter 12, the rail pressure actual value pCR (IST) is determined. This one is with compared to the set point pCR (SL) at a summation point, from which the control deviation dp results.
- From the control deviation dp is a manipulated variable by means of a high-pressure regulator 8 calculated.
- the manipulated variable corresponds to a volume flow qV.
- the physical unit of the volume flow can, for. B. Be liter / minute.
- the volume flow qV the calculated target consumption is added.
- the volume flow qV corresponds to the input quantity for a limitation 9.
- the limitation 9 can be speed-dependent, Input size nMOT.
- the output qV (SL) of the limit 9 is then converted in a function block 10 into a PWM signal. During conversion, fluctuations in the operating voltage and the fuel pressure taken into account.
- the solenoid coil of the suction throttle then becomes the PWM signal applied. This changes the path of the magnetic core, whereby the flow rate of the high-pressure pump freely influenced becomes.
- the pumps 3 with suction throttle and the rail 6 correspond the controlled system 11. From the rail 6 is via the injectors 7 a volume flow qV (VER) dissipated. This is the control loop closed.
- FIG. 3 is a timing diagram for a speed-up run an internal combustion engine with sixteen cylinders.
- the injection period is 45 degrees based on the crankshaft. It was based on this time diagram a PWM signal with a first frequency f1 of 102.4 Hz.
- On the ordinates are the values of the rail pressure pCR and the values of the engine speed nMOT are plotted. As abscissa different time values are shown.
- the angular distance between two injections, the injection period is the number of cylinders of the Internal combustion engine dependent. In a 20-cylinder internal combustion engine can the angular distance z. B. 72 degrees.
- the engine speed exceeds nMOT at point A the speed value 768 revolutions / minute.
- This speed value corresponds to an injection frequency of 102.4 Hz. This frequency is identical to the first one Frequency of the PWM signal.
- the rail pressure actual value pCR (IST) shows from the time t6 significant pressure oscillations with increasing Amplutide. The maximum amplitude (peak / peak) is about 40 bar. After time t8 decreases again the amplitude.
- FIG 4 is a speed diagram for an increasing engine speed (Arrow direction to the right) and a falling engine speed (Arrow pointing to the left).
- a rising or falling engine speed can z. B. based on the speed gradient nGRAD be identified.
- the invention now provides that from the injection period and the first Frequency f1 of the PWM signal calculates a critical speed nKR becomes.
- the critical speed nKR corresponds to z. Eg 768 Revolutions / minute, corresponding to point A of Figure 3.
- first speed range BER1 and a second speed range BER2 set can be z. B. 120 revolutions / minute be.
- the first speed range BER1 is replaced by a defined first limit value n1 and a second limit value n2.
- the second speed range BER2 is replaced by a third Limit n3 and a fourth limit n4 defined.
- first n1 and third limits n3 are for smaller engine speed values set as the critical speed nKR.
- the second n2 and fourth limit n4 are at higher engine speed values set as the critical speed nKR.
- the third limit n3 is opposite the first threshold n1 by a first hysteresis value Hyst1 shifted to smaller engine speed values.
- the value of the first hysteresis Hyst1 can be z. B. 20 revolutions / minute be. It prevents a back and forth between both frequencies in steady state operation.
- nKR critical speed
- the critical speed nKR will increase with increasing engine speed nMOT from the second frequency f2 back to the first frequency f1 is switched back when the second limit n2 is exceeded.
- a switch back to the second frequency f2 takes place at falling speed only when the below the fourth limit n4.
- the fourth limit n4 is a second compared to the third threshold n3 Hysteresis value Hyst2 shifted to smaller engine speed values.
- the two speed ranges arise BER1 and BER2 within which the second frequency f2 is valid is. Outside these speed ranges is the frequency of the PWM signal identical to the first frequency f1. Is that the first frequency f1 z. B.
- Figures 5A and 5B illustrate as state diagrams again the switching mechanism of the first frequency f1 to the second frequency f2 and vice versa.
- FIG. 5A shows that for engine speeds nMOT below the critical speed nKR from the first f1 to the second Frequency f2 is switched when the engine speed nMOT is greater than the first limit n1. On the first frequency f1 is then switched back when the engine speed nMOT becomes smaller than the third threshold n3, accordingly the difference of the first limit value n1 and the first hysteresis Hyst1.
- FIG. 5B shows that for engine speeds nMOT above the critical speed nKR from the second f2 to the first Frequency f1 is switched when the engine speed nMOT exceeds the second limit n2. On the second frequency f2 is then switched back when the engine speed nMOT becomes smaller than the fourth limit n4, accordingly the difference of the second threshold n2 minus the second Hysteresis Hyst2.
- FIG. 6 shows a program flow chart.
- the critical speed nKR from the angular distance of two injections, ie the injection period, and the first frequency f1 of the PWM signal.
- S2 it is checked if the engine speed nMOT is less than the critical speed nKR. is this smaller, then S3 becomes the program schedule of the figure 7 branches. If this is larger, then S4 becomes the program flowchart of Figure 8 branches.
- FIG 7 is a program flowchart for engine speeds nMOT below the critical speed nKR.
- the PWM signal To the starting of the internal combustion engine is at S1 on a flag One set.
- the PWM signal then becomes the first one Frequency f1 set, z. B. 102.4 Hz. Then it is checked at S3, whether the flag has the value one. If this is the case, then is checked at S4, if the engine speed nMOT the first Limit has exceeded n1. If this is the case, then set the frequency of the PWM signal to the second frequency f2, Step S5. The PWM signal is thus switched.
- the flag is set to the value zero and branched to point A. If the query at S4 is negative, then is branched directly to point A.
- step S7 it is checked in step S7 whether the engine speed nMOT the third limit value n3, corresponding to the difference the first limit n1 minus the first hysteresis Hyst1. If this is the case, then the frequency of the PWM signal again set to the value f1, step S8. in the Step S9 then the flag back to the value One set and branched back to point A.

- Durch die Umschaltung der Frequenz des PWM-Signals wird das Entstehen von Hochdruckschwingungen im Rail verhindert.
- Da sich die beiden Frequenz-Werte des PWM-Signals nur geringfügig unterscheiden, sind die Auswirkungen auf die Hysterese der Saugdrossel gering.
- Zur Stabilisierung des Hochdruck-Regelkreises in den kritischen Drehzahlbereichen ist keine weitere Optimierung von Hochdruck-Regelparametern notwendig.
- Da die Zeitkonstanten der Regelstrecke (Pumpen mit Saugdrossel und Rail) im Allgemeinen deutlich größer sind als der Kehrwert der PWM-Frequenz, erfolgt das Umschalten von der ersten Frequenz auf die zweite Frequenz und vice versa nahezu störungsfrei, d. h. ohne Auswirkung auf den Kraftstoffhochdruck.
