    1480131 Ignition systems; timing ignition G HARTIG 7 June 1974 [23 July 1973] 25312/74 Heading F1B In a method of controlling the closed angle of an ignition system of an internal combustion engine a main pulse sequence is produced, the pulses of which are synchronized with the rotary movement of the rotating parts of the engine, and an advance angle α by which the ignition spark is to be advanced relatively to the top dead centre is determined by counting the pulses occurring during a time t and subtracting them, as defined in the Specification, from a number of pulses counted during traversing of a larger angle # which extends between the engine top dead centre and an arbitrary phase position advanced relatively thereto. The ignition pulse is produced when the differential angle # - α has been traversed so that the ignition pulse is advanced by the angle α relative to the top dead centre. A trigger angle # which changes in the same manner as the angle α in dependence on the speed of engine rotation extends from an ignition closing position to the top dead centre, and is represented by a number of pulses dependent on the speed of rotation, the pulses representing the angle being subtracted, as defined in the Specification, from those representing the angle # to cause the operating pulse to be produced after the differential angle # - # has been traversed so that the operating pulse occurs advanced by the closed angle # relative to the advance angle α. Referring to Fig. 3 it is assumed that a pulse has appeared at the output of the comparator 33 and has reset the flip-flop 37 corresponding to the end of a closed angle pulse. The pulse on the output 35 passes through a pulse former stage 38 and then appears on the set input 9 of the counter 8 and triggers the function generator 7. The counter 8 is reset by the arrival of the pulse from the former stage 38 whereas the triggering of the function generator 7 is affected only by the end of this pulse. During the time t as determined by the function generator 7 the gate 6 is opened so that the pulses counted in the counter 8 are those derived from the transmitter 2 during the time t. As soon as a pulse appears from the transmitter 1 the counters 18 and 23 receive set pulses at their inputs 24 and 25 respectively enabling them to take over the pulses stored in the counter 8. Reset of the counter 29 to the condition 000 is simultaneously effected through the set input 30. At the end of the pulse from the transmitter 1 the counter 18 starts counting the pulses appearing from the transmitter 2. The comparator 34 is programmed so that it delivers an output signal at the output 36 when the output of the counter 23 has the condition "0010". The output signal of this comparator sets the flip-flop 37 so that the rise of a closed angle pulse appears at the output 41. The ignition coil primary circuit is closed. The circuit is opened at the end of the pulse appearing at the output 41 causing a spark at the gap of a plug. The time t can be changed from the input 40 in dependence on engine parameters such, for example, as engine temperature, manifold vacuum, temperature of an after burner and so on. A number of alternative embodiments are described. Specification 1313114 and United States Specification 3696303 are referred to.

    CURRENT to create a magnetic field in the ignition coil.  The disk rotates in the direction indicated by the arrow.  As is generally known, the ignition coil, in particular, consists of a primary coil and a secondary coil, with the current in the primary winding turning on at point t (Fig.  1) and is interrupted at point A, so that when it is interrupted, a high voltage is generated in the secondary winding, causing a spark overlap in the spark plug.  The angle between A and z is the angle of closure.  In addition, in FIG.  Figure 1 shows an arbitrary position in phase Cho of the upper dead center OT, from which the counting processes themselves lead to the formation of a primary pulse at point A, representing the beginning of the angle of closure, and of an ignition pulse at the point Z at the end of the angle of closure.   The angle extending from o to OT is here referred to as the initial angle and the angle cL between r and OT is the trigger angle.  A system whose device for generating the main and auxiliary pulses (using the latter controls & ly by the counting operations and the synchronization of the proposed device) is indicated in FIG.  2, contains the first 1 and second 2 sensors, which generate pulses due to the passage of a disk 3 fitted with teeth and gaps and rigidly connected to the shaft of the internal combustion engine, for example, by pressing the crankshaft.  This disk has two areas of teeth or gaps, namely the outer 4 and inner 5 parts, respectively.  At the same time, as in area 4, with which the sensor 2 interacts, the teeth and the gaps are evenly distributed around the circumference (nachfimer, 128 teeth, of which FIG.  2 shows only a part in the region 5 with which the sensor 1 interacts, a considerably smaller number of teeth or gaps is provided (one gap is shown in FIG.  2 wherein the teeth or gaps in region 5 serve to form auxiliary pulses, which in particular control counting operations (t.  e.  the operation of the counters connected to the sensors directly or through intermediate links), thus determines the phase position of the pulses (main pulses) received by the teeth or the gaps of region 4.  In the simplest case, the inner region 5, na1fimer, has only one tooth or gap.  The pulses from the sensor 2 are inputted through the NOT-AND-valve made in the form of a circuit (Fig.  3), which is held in the open state by the generator of 7 functions for a predetermined time t, into the clock 8.  This counter in this case consists of four successively klk) chenn1 binary stages, for example, trigger.  Thus, it has a maximum counting range of 2 16 counting states.  This means that the counter 8 has counting states 0-15.  This counter is made in such a way (for example, with the use of appropriate special circuit diagrams) that when the counting state 15 is reached, it remains in it even if new impulses arrive at the input 6 through the valve 6.  Counter 8 remains at counting position 15 until the pulses are reset at input 9.  The counter 8 has, in accordance with the number of binary stages, four outputs 10-13, which form each input of the binary stage.  The output values of these binary stages are located at the installation inputs 14-17 of counter 18 or 19-22 of counter 23.  These counting states are adopted by both counters 18 and 23 (also consisting of four binary stages each) only when an auxiliary pulse appears in the sensor 1, which is fed to the charging input 24 of the counter 18 or respectively to the charged input 25 of the counter 23 as a command reception.  Counter 18 continuously receives pulses from sensor 2.  The output 26 of the third binary stage of the counter 18 is connected to the counter 1a 1M input 27 of the counter 23, and the output 28 of the fourth binary stage of the counter 18 is connected to the counting input of another counter 29, which has a charging input 30 and also receives from the sensor 1 auxiliary pulses, which are command reception.  Since, however, the installation inputs of the counter 29 do not have connections, this receiving command means receiving a binary LLC number, since this counter is equipped with only three binary steps (it is possible to set the counter 29 with a receive command to another given binary digital value).  The outputs of the individual binary counters 18 and 29 are denoted by a single “1” numerical value 31, which also designates the output 26 of the third binary stage of the counter 18 and the output 28 the fourth binary stage of the counter 18.  Thus, output 31 includes only seven binary stages and is the counting value of counters 18 and 29, which can be one hundred and twenty to seven counting states.  The symbol 32 denotes the outputs of the first three binary stages of the counter 23, although in the illustrated example of execution only the output of the counter 23 is covered.  The counter 29 is connected to the comparison matrix 33, and the output of the counter 23 to the matrix 34.  Outputs 31 and 3 and the output are each equal to one matrix 33 or 34, respectively, each of which can be programmed to any binary value (for example, through the corresponding lines from the outside), so that they only give a signal (for example, a pulse) to its output is 35 or 36, respectively, if the exact binary value for which the corresponding comparison matrix is programmed appears at outputs 31 and 32.  The output 36 is connected to the installation input of the trigger relay 37, the output 35 is connected to the reset output of the trigger relay 37 and simultaneously via the shuhlizer 38 to the reset input 9 of the counter 8 and to the input 39 of the function generator 7.  The counter 8 is transferred back to the binary value 0000, preferably via the reset input 9.  The function generator 7 forms the output signal of duration t always starting when the 39th pulse appears on the trigger input.  Through input 40, the duration t can be changed depending on typical engine parameters, such as engine temperature, suction vacuum, burnout chamber temperature, and so on.  At the output 41 of the flip-flop 37, an impulse appears, the length of which is equal to the length of the closing angle and the front-switching of which closes the switch in the primary circuit of the ignition coil, which causes the appearance of a magnetic field in the ignition coil, appearing at the output 41, opens the switch so that a spark appears in the spark gap.  The device (FIG.  3) works as follows.  It is assumed that at output 33 it is comparable (hectare just in time of the pulse, overturning the trigger relay 37, which corresponds to the end of the closing angle, t.  e.  The point in FIG.  one.  This pulse is output 35. , passing through the pulse shaping stage and appearing then at the input 9 of the counter 8, must rearrange the counter 8 back, and in the present case to the binary value of the GETH and start the function generator.  It is also possible to set in the counter through the shown inputs with the appearance of a pulse at input 9 and another binary value.  It is not necessary, however, to transfer counter 8 back a little before starting the generator of 7 functions.  For this purpose, a pulse shaper 38 is provided, which forms a short rectangular pulse from the pulse output at 35, during this short rectangular pulse, the counter 8 is transferred back, while the start of the function generator 7 is performed only with the help of this cut-off front, momentum.  During the next predetermined time interval t of the function generator 7, the valve 6 is open, so that in counter 8, as many pulses are counted as VIX appears in sensor 2 during time t.  This means that the higher the frequency of rotation of the disk 3, the more pulses are counted in the counter 8.  As soon as an auxiliary impulse appears in sensor 1, counters 18 and 23 are received via inputs 24 or 25, respectively, the command of the state of counter 8, corresponding to the number of pulses appearing during time t, simultaneously through input 30 of the transducer back to position 000.  From the moment the auxiliary pulse disappears, the counter 18 counts on the pulse 2 in the sensor 2 pulses.  With each transition of the state of the counter 18 with lllX (. t.  about.  1110 or 1111) for the state of LLCX (t.  e.  OOO1 or OOOfj) counter 23 receives at the input 7 a counting pulse, t.  e.  the counter acts as an 8-fold counter for the meter: a 23.  When each change of the counter 18c of the state 1111 to 0000, the counter 29 receives a monthly impulse.  With the help of the given counting pulses; (chapters 1x) counters 29 and 23 continuously switching on.  In the general counting state, the LLC 18 counters 18 and 29 (this state corresponds to receiving 32 pulses in the counter 18, received either through inputs 14-17 and / or from the sensor 2 pulses via the count input), on which the matrix is programmed 33 comparisons, a pulse appears at the output 35 of this matrix.  By linking the counter for 23 hours & -.  the cut counter 18 achieves the selective counting by the counter 23 of only each pulse generated in the sensor 2. At the output 32 of the counter 23 there appears a position corresponding to the sum of the counting pulses transferred by the counter 8 through the inputs 1922 and entered by the counter 18 through the counting input 27 impulses.  The control matrix 34 in the present case is programmed so that it gives the output signal at output 36 if the output 32 of counter 23 shows the OOU counting state, which corresponds to the counting of four pulses in counter 2 The source signal of this matrix sets the trigger 37 so that at the output 41, the rising edge of the closure angle pulse appears.  Thus (FIG.  4), reach the following.  Since sensors 1 and 2 are positioned so that at the lowest number of revolutions, at least one pulse is counted in the counter at low frequencies, and the following revolutions occur.  On the counter 1-stroke 8 binary signal is 1000.  This signal is received by counters 18 and 2 3 with an auxiliary signal appearing in sensor 1.  This auxiliary signal appears at point O (FIG.  four).  Since, at the end of the auxiliary pulse, the counting pulse 1 in the sensor 2 begins at the same time and starts at one thirty eight. tooth, t.  e.  in fig.  4 at point 31 (since each of the Arabic numbers of FIG.  4 means the number of the tooth, counted from point O), a pulse appears as the comparison matrix is programmed so that it gives a pulse, if the output 31 has a counting state corresponding to thirty-two pulses in the counter 18 (both through the setup inputs and through the account ky entry in general).  Since the counter 18 started counting with the appearance of an auxiliary pulse corresponding to one pulse, and since the output at the output 26 with every eighth pulse in the counter 1 8 at the input 27 of the counter 23 appears a counting pulse, the count of the counter 23, which when the auxiliary pulse appears also, it was brought to the state corresponding to the counting of one pulse, transferred to the state 0100.  This corresponds to the counting of two pulses, if the counter 18 received from the sensor 2 seven pulses, t.  e.  tooth seven (fig.  four).  Since with further counting, the counting of the counter 23 increases each time with a single pulse, always if eight teeth go past the sensor 2 again, the count of the counter 23 reaches the twenty-third tooth of condition 0010, on which the matrix 34 is programmed.  Therefore, it gives a pulse to the input of the trigger 37, which triggers the pulse of the closure angle, in other words, it corresponds to the Rising ({closure font) (FIG.  1 point A).  In this case, the impulse S covers the area of eight teeth (tooth 23-31 in FIG.  4) with a relatively slow peripheral speed.  At a slightly higher number of revolutions, time t corresponds to the passage of two teeth past the sensor 2.  Counters 18 and 23 accept the binary value corresponding to the account 2 of the counter (0100).  The counter 23 receives the first pulse through the outputs 26 and 27 when the sixth impulse appears in the sensor 2, so that its count goes to the LEO.  Then, eight more pulses of sensor 2 must follow until the counter reaches 23, at which the matrix 34 sends one pulse.  This takes place after a total of 6 + 1x8 sensor pulses of 2, m.  e.  at point 14 of fig.  four.  Counters 18 and 29, however, after receiving the account of counter 8, must receive another 32-2V from sensor 2. ZO pulses before the output matrix 33 pulses at the output 35.  Thus, in FIG.  4, a pulse at the point 14 appears, corresponding to the beginning of the pulse 9 (closing angle, while a pulse corresponding to the end of the closing angle and, simultaneously, the ignition time point appears at point 30.  The ratios are given in more detail in Table.  one .  91 midrange (with the device 18 for recoil of the pulse by the magnum (point in FIG.  4, where the 35th pulse appears at the output); the number of pulses that must appear in sensor 2 from the moment of reception to the impact by the matrix 34 of the pulse (the point in FIG.  4, where the 36th pulse appears at the output) the difference between the values of the column And of the column U, t.  e.  the number of pulses of sensor 2, by which the pulse at output 36 is ahead of pulse 35 (you should pay attention not to the fact that tooth 124 corresponds to the fourth tooth before O), the quotient of division IV and 1, t.  e.  the length of the closure angle relative to the length of the angle A of the ignition permutation.  In the case of higher numbers, when the reception value is five or higher, t.  e.  exceeds the start value of the matrix 34, the counter 23 must first receive so many pulses that in the subsequent countdown cycle of this counter the value of the start of the OOU of the matrix 34 is reached.  If, for example, with О, the counter 23 takes the value of five, it must continue to measure down to the tooth one hundred and fifteen (the 5th horizontal column of the table.  1), where the trigger value of the matrix 34 is reached, and as a result, it forms a primary impulse, which causes the beginning of the impulse angle 5 5 of the angle (FIG.  4 This impulse Sj, when the trigger value of the matrix 33 is reached, stops at the tooth of the twenty-seven above METHOD G1.  Since the count of counter 23 in the area of teeth 115-123 is a binary value 0010, corresponding to a value of 4, t.  e.  at 128 or O at the receiving point is equal to the binary value of 1010 (corresponding to a decimal value of 5), due to the new reception of the value of 5 at this point, the counting cycle of the counter 23 is not subjected to correction.  This is because the counting cycle of the counter 23 and the counter 18 is selected so that it corresponds to the number of main pulses per revolution.  , A special case is the acceptance of the value 4, which is simultaneously the trigger value.  When switching from low speeds, corresponding to 8 receiving value 3, to number o6q3t com, corresponding to receiving value 4, the primary pulse appears at input 36 at the moment of reception, t.  e.  with O in FIG.  four.  With a turnaround turn, however, the counter 18 is moved forward to the value 4, so that during this cycle and all continuous cycles with the same receiving value 4, the primary impulse appears already at the tooth, 124 tab.  1, 4th horizontal column).  How is it clear from the table.  1 (column V), the magnitude of the angle H of the closure relative to the start angle oL, depending mainly on the gear ratio of the counter 18 (or, respectively, the gear 23 (FIG.  9) in combination with the programmed value of the matrix 34, varies in the range of approximately 7, 1-8.  This range, in which the relative magnitude of the closing angle oscillates in the appropriate case, arises in the case of the present embodiment from the fact that the counter 18 operating for counter 23 as a gearbox takes over because of its function as a trigger counter for matrices 33 (together with counter 29) also counts counter 8 when an auxiliary pulse appears at point 73.  If a special gearbox were connected in front of counter 23 (gear 23 b in FIG.  9), which would receive only pulses directly from sensor 2 (r.  e.  not through the counter 18), it would not have been possible to oscillate the relative value of the angle of closure, as is clear from column V of the table.  2  The latter considerations, however, are valid only if the number N distributed around the circumference of the disk 3 in the 4 teeth region is equal to the derivative of the number N of possible counting states of the counter 8 multiplied by the reciprocal of the gear ratio q, the gearbox, in other words The present case, N -ixi: 9, is obvious.  If the number N deviates from this value, oscillations of the relative magnitude of the closing angle are also formed, which, depending on the magnitude of the deviation, may or may not be acceptable.  In all cases, caused by counter 18 (FIG.  3) the oscillation range is from the junction of the closing angle (column V of the table.  1) is admissible and insignificant in comparison with the fact that in this way an additional gearbox disappears (23 ti in FIG.  91).   It is also possible to choose a larger number of teeth or gaps than x1: ci, in particular according to the relation where n is a positive factor, more than 1, preferably an integer.  If, for example, clause 2, the following relationships are obtained, illustrated with fig.  5 (FIG.  5 mainly corresponds to FIG.  4, however there are 2 56 teeth on the disc).  As a diagram, an embodiment of FIG.  3  If, for example, a single tooth falls at a given time (Table  1, the first horizontal column), then the angle of closure extends from tooth 23 to 31.  Through the 128 teeth, the same is repeated, so that between the teeth 1 51 and 159 a closing angle of the same magnitude appears.  Thus, the closing angles appear distributed centrally symmetrically around the circumference of the circle of FIG.  5, if n is an even number.  If n is an odd number, then the second, (and, if appropriate, larger) angle of closure appears due to the periodicity of the counter 128 teeth later, so that the angles of the closure are not centrally symmetric.  These closure angle pulses are across (FIG.  3) at the same exit 41.  For distributed ignition, it is desirable that (as in FIG.  13) different closure angle pulses appeared at different outputs.  One of the possibilities of achieving this position is achieved in the embodiment shown in FIG.  6  This variant corresponds to the variant of FIG.  3, however, here the output 41 is connected to the input of the circuit NON-I 42 and the output of the circuit NOT-I 43.  Both other inputs of the circuits are connected via an inverter 44, the input of which is connected to the output of divider 45, as a result of which, depending on the state at the output of divider 45, one or the other is open.  The state at the output of divider 45, whose input is connected to output 35, changes each time a pulse (ignition pulse) appears on this output.  In FIG. 5, this is the first occurrence in a 31 tooth, where the exit state changes from 0 to 1.  Here the next closure angle pulse appears at the output 46 of the circuit 42 with the appearance of a pulse ((ignition pulse) of the 159 teeth at the output 35 of the output divider 45 state switches from 814 to O, so the next closure angle pulse (base between teeth ovaotsati three and thirty-one) appears at exit 47, and so on.  Synchronization input 48.  the divider 45 is connected to the output 46, so that the tooth O shsh, respectively, two hundred and fifty and six states at the output of the divider 45 has the value O; The variants depicted in FIG.  7-9 (although not as simple as the variant of FIG.  3) are also relatively preferred with respect to the prior art.  In particular, these options (in the numbering sequence of figures) can be considered as preliminary steps of the particularly preferred options of FIG.  3, so that the following clarification at the same time is an additional clarification of the embodiment of FIG.  3 principles.  In the embodiment of FIG.  7, the function generator 7 is colored in such a way that it is equipped with two outputs 39 and 39 b, with output 39 a (as in FIG.  3) an impulse is formed, the length of which is. It is equal to the specified time i, which corresponds to the advance angle, while output 39 b receives a pulse whose length T corresponds to the length of the advance angle d plus the length of the transposition angle, t.  e.  the time is equal to the sum of the time -fc 7 required for creating the magnetic field in the ignition coil, and the specified time t by which the ignition must be shifted forward relative to the upper dead center OT.  Output 39 b is connected to the input of the additionally inverted element And b, to another input of which the output of the sensor 21 is connected.  As a consequence, the counter 8 accumulates the number of pulses corresponding to the time T at a given frequency of rotation of the disk 3 (Fig.  2).  This counter can accordingly be transferred back to the counter 8 via the reset input 9 if a pulse appears through the pulse shaper 38.  If, on the other hand, an auxiliary 1 pulse appears in sensor 1, causing counter 18 to receive count 8 and counter 23 to count 8 (at point O of FIG.  4), and both matrices 33 and 34 are set on the same and the same trigger value and give each pulse when the corresponding counter reaches 18 or 23, respectively, of a given count, then c.  In this case, after a certain first number of pulses of sensor 2 at point 36, a pulse appears, since Tb is greater than t, and a little later, a pulse at point 35.  Both of these pulses correspond to points 2.  and A of FIG.  1 (a given count is chosen higher than the expected count values of counters 8 and 8; the device of FIG.  7 includes the minimization of the angle H of the closure and gives, at the output 41, a pulse corresponding in magnitude and position in phase to the optimal angle of the closure.  In this connection, it should be pointed out that for the device under consideration (in particular in FIG. 6), it does not matter in which direction the counters 18 and / or 23 count to reach the trigger value of the matrix 33 or 34, respectively, forward or back - and load them with a number of pulses before counting, in particular, those that generally correspond to those provided in matrix 33 or 34 corresponding to the trigger value, and only then negatively receive pulses from counter 8 and 8 and subtract pulses from the sensor 2 so that 33 and 34 with On chenii be given momentum It relates and other respective embodiments of, poskop ku latter method is a kinematic conversion processes with the use of embodiments of the method.  It should also be pointed out that in the corresponding case, instead of binary parallel input of the counting values of counters 8 and 8 into counters 18 and 23, serial input can also be performed through the counting inputs or by appropriately positioning the gates and controlling the Pm before counters 18 and 23, t.  e.  do without counters 8 and 8.  The same can be said about the other variants of execution.  In this connection, it should be emphasized that, in addition to serial input and / or in addition to parallel input, other (in this case not serving for synchronization) auxiliary pulses can be entered through the counting inputs, which results in the same effect as changing the program code. matrix values 33 and / or 34 and / or 49 and / or 5O.  Putting these aids. "  powerful impulses are carried out at predetermined positions in the phase of the perisonal motion.  The embodiment of FIG.  8 corresponds to the embodiment of FIG.  7, however, the counter 8 and the valve b are omitted here, and the generator 7 of functions is executed similarly to FIG.  5, t.  e.  at the output of the ZE, it gives an impulse, the length of which corresponds to the grapple d of the advance.  In addition to the counter x 8, the counter 23 is connected to the counter 8.  The counter 18 receives when the auxiliary pulse is detected in the sensor 1, the counting value of the counter 8.  This value is multiplied many times in the multiplier 23 "(Fig.  8) located between the W} 1 input of the counter 8 and the installation input of the counter 23, for example, up to 7 or 8 times, which is then received by the counter 23.  Thus, the image (% 1, the angle H of the closure acquires a multiple value of the angle oL of the permutation, and both matrices 33 and 34 can be grinded to the same trigger value.  If, for example, the reception of the counter of the counter 8 equals Q, the counter 18 receives the counting value 9, and the counter 23 receives the BS (in the sevenfold multiplication).  If the trigger value of the matrices 33 and 34 is set to & 96, then (in the case of the counting of the pulses of the sensor 2 s O of FIG.  4) a pulse appears at exit 36 at point 96-63 (Fig.  4) and another pulse is output 35 at the point (in FIG.  4), and in this case, the upper, dead point corresponds to point 96 (FIG.  four).  Of course, it is possible to place the gearbox between the counters 8 and 18 and connect the counter 23 directly to the counter 8 (t.  e.  not through 2Sa), but this method is not preferable, in particular, because the accuracy of the permutation or advance angle plays a much larger role than the magnitude of the angle of closure, the latter should not exceed the limits of a certain minimum value, otherwise may well fluctuate in a certain range.  In the embodiment of FIG.  9, both counters 18 and 23 (as in FIG.  3) they adopt the same counting value from counter 8, but in this case, before the counting input of counter 23, a reducer 23b is turned on, transmitting, for example, every eighth pulse of sensor 2 to counter 23.  At the same time, the matrix 34 is programmed so that it gives a trigger pulse at a value equal to the trigger value of matrix 83 multiplied by the gear ratio of gearbox 23b (FIG.  9).  Therefore, if matrix 33 is programmed to a trigger value of 32, and the gear ratio of the gearbox is 1/8, matrix 34 is programmed to a trigger value of 32x1 / 8 4.  Otherwise, the device of FIG.  9 can be constructed similarly to the device of FIG.  3 (including counter 29).
    It becomes clear when comparing FIG. 3 and 9, the advantage of the device of FIG. 3 compared with FIG. 9 lies in the fact that there is no special gear 23to, because the counter 18. (Fig. 3)
    simultaneously performs the function reduct-1 $, the next. pa 23 b. In this case, as is clear from the tables, it becomes necessary to take into account a certain range of fluctuations in the relative angle of closure H: cL. However, as mentioned above, this is not acceptable. FIG. 10 is a diagram of FIG. 3 with an additional set of switches containing elements 51, 52, and 53 to prevent incorrect pulses from being generated and starting the engine. This is particularly important for the reason that the reference processes in the diagram of FIG. 3 already occurs when pulses appear in sensor 2. During the first output shaft of the internal combustion engine, the counters (Fig. 7) are not synchronized with the movement of the internal combustion engine until sensor 1 has an auxiliary pulse (which can It would be called the impulse of a conditional point or synchronization) or a derivative of an auxiliary impulse of a conditional point or synchronization pulse. The entire course of the program, prefigured in the scheme of FIG. 3, is provided only if a trigger pulse is opened at input 39 at least once. A further diagram of FIG. 10 (only parts modified relative to Fig. 3 are depicted, which refers to the subsequent figures and Fig. B) include two trigger relays 51 and 52, which have the property of taking a given state when the operating voltage is turned on, in the present case O that can be achieved by certain inclusion operations. The input 54 of the trigger 51 is connected to the output 55 of the sensor 1 so that the position of this trigger on b1-course 56 when the pulse appears in the sensor, ke 1 goes to position 1. The input 57 of the trigger 52 is connected to the trigger,
    pulse input 39 of the function generator 7, so that the output 58 of this trigger, when a trigger pulse appears in 39, is tilted to the position. Outputs 56 and 58 are each connected to one input of an AND 53 element, the third input of which is connected via line 35 of matrix 33, and the output of which through output 35 b to the reset input of trigger 37 located in FIG. 3 directly at the exit of the matrix 33. Scheme 53 is to some extent connected to the output (DN 35 (FIG. 3).
    The principle of the circuit operation (Fig. 10). In order for the pulse appearing at the output 35 to have an effect in the trigger 37, the circuit 53 connected to the flip-flops 51 and 52 should show state 1. This, however, is possible only if the outputs 55 and 39 pulse wils at least once. As a consequence, a pulse appearing at the output 35 can perform the function of an ignition pulse only after synchronization of the counting processes with the flow of motion. If the accuracy of the first ignition pulse decreases, or if the counter 8 (by appropriate execution), sa t, takes the OOOO state when it is turned on, the trigger 52 may not be present, and the circuit 53 can be made as a double element I. It should be noted that locking the device before synchronization can be performed in the appropriate other place. Ignition coils can be made much smaller and cheaper if they are protected from thermal overload, i.e. if, despite the ignition on, the current of the ignition coil is limited. This can be achieved using the circuit of FIG. 11 by applying a periodically returning pulse train, preferably output pulses at the output 59 of the sensor 2, and an input .60 of a launchable back (monostable) multivibrator 61, having state I at the output 62, until the time interval between the individual pulses of the pulse series below the proper time of the multivibrator 61, which takes place from a given minimum number of revolutions. The signal appearing at output 62 is fed to one input of the NAND circuit 63, the other input of which is connected to the output 41 of the flip-flop 37, while the output of section 63 directs to the ignition coil, so that the flow of current from Bbixoaa 41 to the ignition coil stops ischeted through the circuit 63 only in the presence of a certain minimum number of revolutions. In order to prevent spontaneous current interruption to the ignition coil, which would cause an undesirable ignition pulse, between the HODSM4 62 and the input of the circuit 63 is provided; an additional device preventing this sudden interruption. This additional device may be a capacitor located between connection 62 and ground, or a generator of sawtooth oscillations with a cut-off front edge, or the circuit 63 itself can take over its function if at. change slowly closing circuit. On the basis of the development of a system in the form of a digital system, it is possible to conduct a program of detecting one’s own narratives of the system. Thus, for example, the system would stop working flawlessly and would cause a danger to the internal combustion engine if the synchronizing sensor 1 had failed. Such a danger is warned by the electric circuit of FIG. 12. Here, the counter 64 is connected via the counting input 65 from the inputs 39 of the trigger pulse, and through the reset input 66 to the output 55 of the sensor 1, the Output 67 of the counter 64 is connected to one of the inputs of the NAND circuit 68, the other input of which is connected to the OUT1 41 and the output of circuit 68 leads to an ignition coil (or ignition device). The principle of operation of the scheme is as follows. Since the impulse at the input 39 of the generator 7 functions and the impulse in the sensor 1 can occur only once and the phase of the movement (this present execution program), there is a dangerous error if at the input 39 several times an impulse appears between two pulses of this kind, a pulse from sensor 1 would be sent. Thus, with an alternative to left-handed counter 64, it can interrupt a maximum of one pulse. The counter is made such that state 67 is usually present at output 67, but when a more than one pulse is detected at output 67, state O appears, so no more pulses are sent to the output. At the same time, a safety device 69 can be connected to the output 67, for example a safety signal 9 8 va lamp toiH buzzer activated by output signal 1 at output 67 1 controlled from it. Separate pulse trains that are displaced relative to each other are required to ignite multistage engines. For example, a two-cylinder engine requires two initial pulses located at the ISO distance of the shaft angle. These pulses can be obtained using the circuit of FIG. 13 in such a way that in the scheme of FIG. 3 to the outputs 31 or 32, respectively, connect the inputs of two other decoding matrices 49 and 50 and are programmed in such a way that they form impulse on their drives 70 and 71, which follow at an angle of 180 to appearing at output 35 or 36 corresponding to the corresponding impulse. Outputs 70 and 71 of I are connected to the inputs of trigger relay 72 (similar to the connection of outputs 35, and 36 with trigger 37), so that at its output 73 there appear closure angle pulses that are displaced relative to 41 of the closure angle pulses 180 and control the ignition (including ignition of the ignition coil) of the second cylinder of the engine. So, for example, on the circumference of square 3 with one hundred and twenty-eight teeth in area 4 (Fig. 2), the switch-on or trigger value of the matrix 49 is set to a value 64 above the switch-on or trigger value of the matrix 33 or 34, and the switch-on or trigger value of the matrix 50 - to value 8 (due to reduction). As is clear from FIG. 14, the pulses appearing at the output 41 and / or 73 can directly turn on the powerful transistor 74 through its base, and the igniter transponder 75 is located in the circuit of the high voltage transponder, the secondary winding of which is connected to the spark plug P (or to several spark plugs) . In particular, the high-power transistor 74 may be a Darlington transistor, and links or elements that forge them: ignition pulses may be provided between the ignition transformer and the spark puller. Especially 1FOSTO ignition is carried out, if (Fig. 15) thyristor 76 includes direct output 36 matrips 34, in whose current circuit there is a transistor 75 Zyzh11ha1sh ", 1 thyrocyr hash thyristor by means of an auxiliary device 77, directly generated from output 35 of matrix 33 .
