Definitions

  • the change in the fuel metering to the individual cylinders is carried out in such a way that the total amount of fuel supplied to the machine remains unchanged.
  • a device is also known from US Pat. No. 4,179,922 in which the mean value formed across all cylinders is used as the setpoint for the period between two burns.
  • the object of the invention is to carry out the correction of the fuel quantities to be injected into the individual cylinders quickly, precisely, safely and with the aim that each cylinder delivers the same torque and that this results in smooth engine running.
  • This object is achieved on the basis of an electronic device for controlling the fuel metering of an internal combustion engine according to the preamble of claim 1 by the characterizing features of claim 1.
  • FIG. 1 shows the basic structure of a smooth running control for an internal combustion engine
  • FIG. 2 shows the timing diagram of this smooth running control
  • FIGS. 3 to 5 show possibilities for integrating the smooth running control into an existing fuel metering device.
  • FIG. 1 shows the structure of a smooth running control for an internal combustion engine.
  • This smooth running control 10 comprises z controls 11, 12 and 13, where z is the number of cylinders of the internal combustion engine. Furthermore, the smooth running control 10 includes storage devices 14, 15 and 16, two synchronization devices 17 and 18, and a device for forming an average value 19.
  • FIG. 1 also shows an idling control 20, one of the position of the accelerator pedal dependent control 21, a fuel metering device 22 and the internal combustion engine 23 are shown.
  • the z controls 11, 12 and 13 are now connected on the one hand to the respectively associated z storage devices 14, 15 and 16 and on the other hand to the output of the device for forming an average value 19.
  • This device 19 is acted upon by the output signals of all z memory devices 14 to 16.
  • the inputs of the z storage devices 14 to 16 are connected to the synchronization device 17, while the outputs of the z controls 11 to 13 are connected to the synchronization device 18.
  • These two synchronization devices 17 and 18 are now controlled by a signal dependent on the internal combustion engine 23.
  • the internal combustion engine 23 itself is connected to the fuel metering device 22, which in turn is connected to the synchronization device 18, the idle control 20 and the accelerator pedal-dependent control 21.
  • FIG. 2 this is a time diagram of an internal combustion engine with four cylinders. The period of two crankshaft revolutions is shown, i.e. 720 ° KW. During this period, combustion took place in each of the four cylinders.
  • I and J denote two actual signals that are generated using a segment wheel.
  • This segment wheel which is connected to the crankshaft, has four segments which are distributed symmetrically on its circumference.
  • Each pulse of the actual signal J now corresponds to a segment of this segment wheel.
  • the length of each pulse of this actual signal J corresponds to the time it takes for a segment of this segment wheel to to pass through the plane perpendicular to the segment wheel. Since four segments of the segment wheel pass through the imaginary plane during a crankshaft revolution, but since only two burns take place in the cylinders during this time, exactly two segments of the segment wheel pass through the imaginary plane perpendicular to the segment wheel between two burnings.
  • the time between two burns is thus divided into two time segments with the help of these two segments of the segment wheel. Due to the symmetry of the segment wheel, and since the crankshaft angular velocity is always somewhat higher immediately after combustion than immediately before combustion, these two time periods, e.g. B. J21 and J22 always different sizes. The shorter of the two periods, e.g. J21, always indicates that combustion has taken place, while the longer of the two periods, e.g. J22, announces an upcoming combustion.
  • the simulated combustion times V of the individual cylinders which are also called synchronization signals, can be precisely determined with the aid of the actual signal J.
  • These combustion times V of the individual cylinders and their relationship with the actual signal J are shown in the time diagram in FIG.
  • This determination of the combustion times V from the actual signal J is carried out in both synchronization devices 17 and 18 of FIG. 1.
  • the synchronization device 17 switches the actual values 11, 12 and Iz to the corresponding storage devices 14, 15 and 16 with the aid of the simulated combustion times V, these actual values li, 12 to Iz also being formed by the synchronization device 17 with the aid of the actual signal J.
  • the actual values 11, 12 to Iz are each the time periods between two combustion times, as shown in FIG. 2.
  • the synchronization device 18 likewise uses the actual signal J to determine the simulated combustion times V, and thus applies the control values S1, S2 and Sz formed by the control devices 11, 12 and 13 as control signal S to the fuel metering device 22.
  • the control signal S is shown in the time diagram of FIG. 2. It consists of the control values S1, S2 to Sz of the individual cylinders, these control values being formed by the associated control devices. So z. B. the control value S1 is produced by the control device 11 from the actual value 11 buffered by the storage device 14 and an average value Mz. The mean value Mz is formed by the device 19 from all temporarily stored actual values 11, 12 to Iz.
  • This control value S3 is activated shortly after the time T so that the associated control device can also set this new control value. This means that this new manipulated variable is dependent on all previous actual values.
  • the entire smooth running control 10 thus generates an actuating signal S for actuating the fuel metering device 22 from an actual signal I, which is obtained with the aid of a segment wheel. influenced by an idle control 20 and / or by an accelerator pedal-dependent control 21.
  • the fuel metering device 22 determines z. B. the amount of fuel to be injected into the internal combustion engine 23.
  • the smooth running control 10 must be integrated into the entire injection system of the internal combustion engine. This is e.g. possible that the smooth running control 10 can only influence the entire injection system dynamically. For this dynamic influence, the sum of the manipulated values S1 to Sz must be 0, i.e. it must be the average amount of fuel that is supplied to the internal combustion engine less or more due to the smooth running control over z injections 0. This requirement for the integration of the smooth running control 10 into the entire injection system can e.g. B. with the help of one of the changes shown in Figure 3 to Figure 5 of the smooth running control.
  • FIG. 3 shows the block diagram of part of the smooth running control, in this example the integration of the smooth running control in the entire injection system is realized by subtracting the mean value of the control signal S from the output signals of the integrating components of the controls assigned to the individual cylinders.
  • the control 11 consists of an integrating component 30, a proportional component 31, two subtraction points 32 and 33 and an addition point 34.
  • the input signals 11 and Mz supplied to the control 11 are first linked to one another at the subtraction point 32.
  • the output signal of this subtraction point 32 is supplied to the integrating component 30 and the proportional component 31.
  • the output signal of the proportional component 31 is connected to the addition point 34, which is further subjected to the output signal of the subtraction point 33.
  • This output signal of the subtraction point 33 is formed on the one hand from the output signal of the inte limiting portion 30 and from the mean value of the control signal S.
  • the output signal of the addition point 34 now represents the control value S1, which is fed to the synchronization device 18.
  • the output signal of this synchronization device 18 is the control signal S, which is fed to a device for forming an average 35, the output signal of which then represents the average of the control signal S.
  • This device for forming an average 35 can consist, for example, of a low-pass filter.
  • control signal S is not only fed back to the control 11, but also to the controls 12 to 13 assigned to the other cylinders. This feedback of the control signal S to all the controls 11 to 13 of the smooth running control 10 is achieved that the mean value of the control signal over z burns is 0.
  • the smooth running control is integrated into the entire injection system by subtracting the mean value of the integrating components of the controls assigned to the individual cylinders from the output signals of these integrating components of the individual controls.
  • the control 11 then consists of an integrating component 40, a proportional component 41, two subtraction points 42 and 43 and an addition point 44.
  • the input signals 11 and Mz fed to the control 11 are connected to one another at the subtraction point 42.
  • the output signal of this subtraction point 42 is supplied to the integrating component 40 and the proportional component 41.
  • the output signal of the integrating component 40 is now connected to a summation point 45, which is further subjected to the output signals of the integrating components of the controls assigned to the other cylinders.
  • the output signal of this summation point 45 is fed to a device for forming an average value 46, the output signal of which is connected to the node 47.
  • This connection point 47 is linked to all the controls assigned to the individual cylinders.
  • the connection point 47 is connected to the subtraction point 43, which is further subjected to the output signal of the integrating component 40.
  • the addition point 44 is connected on the one hand to the output signal of this subtraction point 43 and on the other hand to the output signal of the proportional component 41.
  • the output signal of the addition point 44 represents the manipulated variable S1.
  • FIG. 5 shows a further possibility of integrating the smooth running control into the entire injection system, in which the mean value of the control values of the controls assigned to the individual cylinders is subtracted from the output signal of the integrating components of these controls.
  • Regulation 11 is e.g. from an integrating part 50, a proportional part 51, two subtraction points 52 and 53 and an addition point 54.
  • the input signals 11 and Mz fed to the control 11 are linked together at the subtraction point 52.
  • the output signal of this subtraction point 52 is now fed to the integrating component 50 and the proportional component 51.
  • the output signal of the integrating part is connected to the subtraction point 52, the output signal of the proportional part to the addition point 54.
  • This addition point 54 is also subjected to the output signal of the subtraction point 53, the output signal of this addition point 54 represents the manipulated variable S1.
  • This manipulated variable S1 is led to an addition point 57, to which the manipulated values of the controls assigned to the other cylinders are also connected are.
  • the output signal of this addition point 57 is fed to a device for forming an average value 56, the output signal of which is connected to a node 55.
  • this connection point 55 all the controls associated with the individual cylinders are connected, such as e.g. is shown in the control 11 with the connection of the node 55 to the subtraction point 53.
  • the smooth running control described is only intended to prevent the vehicle from vibrating in the lower speed range, especially when idling. This is achieved by the fact that the smooth running control is only effective in a certain speed range.
  • the transition areas from this area of the active smoothness control to speeds at which the smoothness control is not effective can e.g. B. covered with a control of the smooth running control.
  • the output variable of the smooth running control is further multiplied by a fuel quantity-dependent factor which is between 0 and 1 in order to achieve a soft increase in the manipulated variable in the event of a sharp drop in speed.
  • the actual signal that is to say the time period between two combustion times, was determined with the aid of the segment wheel. It is also possible to generate a speed signal using a fast tachometer generator or by means of a gearwheel with a subsequent pulse generator and frequency voltage converter. An actual signal for the smooth running control can be generated by integrating this speed signal from injection to injection or from synchronizing pulse to synchronizing pulse. A further possibility for generating the actual signal would be a peak value evaluation of the speed signal between two injection quantities.
  • the combustion times required for the provision of the actual signal are determined in the smooth running control described by dividing the time period between two combustion times into two time segments. Since the switching of the actual signal to the storage devices and / or the switching of the control values to the fuel metering device may not take place exactly at the time of combustion, it is possible to extend the smoothness control described with the aid of a counter so that this counter is converted from a reference signal, e.g. B. is reset by a needle stroke pulse, an injection start pulse, a combustion start pulse, etc., and controls the two synchronization devices at certain, predeterminable counter readings. This makes it possible to generate the switching through of the two synchronization devices at arbitrary, but fixed times.
  • a reference signal e.g. B. is reset by a needle stroke pulse, an injection start pulse, a combustion start pulse, etc.
  • the counter can now either count up as a function of speed and then deliver the synchronization pulses to the two synchronization devices at certain counter readings, or it counts up at a fixed frequency and determines the synchronization times depending on the speed. It is also possible that the counter is reset with every synchronization pulse and with every reference pulse.
  • the four segments of the segment wheel were distributed evenly over the circumference of the wheel. With the help of these segments, the time between two combustion times was divided into a short and a long period. To reinforce the difference between these short and long periods of time, it is now possible to design the segments of the segment wheel asymmetrically. In the case of the described smooth running control in an internal combustion engine with four cylinders, this would mean that only two opposing segments have the same length. This asymmetry has no influence on the determination of the actual signal I, since the actual signal I represents the time period between two combustions and this time period comprises two segments.
  • the segment wheel divides the time between two combustion times into a short and a long period. Interference signals with a lower frequency than the injection frequency can now be superimposed on these time periods. This means that short and long periods of time are no longer evenly changed.
  • the synchronization devices now determine whether a time segment is longer than the previous and the following, they carry out a maximum time check. A synchronization counter, which is increased by 1 at the end of each time period, is always checked when the maximum time check e.g. has noticed a long period of time. If the synchronization is correct, the ends of the long periods of time always fall on z. B. odd-numbered synchronization counts.
  • the synchronization is incorrect. If an incorrect synchronization is detected, it is checked whether in the next e.g. An incorrect synchronization occurs again after 20 periods. The synchronization is only changed if this is the case.
  • control signal S was fed to the fuel metering device 22, which then e.g. influences the amount of fuel to be injected into the internal combustion engine. It is of course also possible that the control signal S indirectly or directly influences other control variables of the internal combustion engine, e.g. the exhaust gas recirculation, the injection timing, the injection duration, the fuel / air ratio, the ignition timing, etc.
  • the device shown and described in Figures 1 to 5 can e.g. can be realized with the help of an analog circuit structure. It is particularly advantageous to use the described smooth running control and, if necessary, also other control and / or regulating devices for fuel metering, e.g. using a suitably programmed microprocessor. With such a computer solution, however, it is then possible that the block diagrams shown can no longer be recognized, since they have been replaced by subroutine structures, time-division multiplexing, etc.
  • the smooth running control described can be used in internal combustion engines of various functional principles, that is to say in self-igniting internal combustion engines, in spark-ignited internal combustion engines, etc. It is particularly advantageous that depending on the function principle of the internal combustion engine, the control assigned to each cylinder of the internal combustion engine directly or indirectly influences a number of control variables of the internal combustion engine.
