Ib) and by means of two semiconductor switches (13, 14) either via the primary winding (9a) of a first ignition coil (9 ) or the primary winding (JOaJ of a second ignition coil (10) can be discharged.

The invention relates to a capacitor ignition device for internal combustion engines with a permanent magnet generator, at least one capacitor of one in a charging winding of the generator generated and rectified alternating current can be charged and by means of a controllable semiconductor switch can be discharged at the ignition point via the primary winding of an ignition coil and at the further for Prevention of charging a controllable shunt to the capacitor is provided.

Such an ignition device is known from DT-OS 54874. In the known ignition device should the controllable shunt cause the machine to overspeed, d. H. Prevent excessive speeds. to for this purpose it is dependent on a voltage proportional to the speed after exceeding one of the threshold values corresponding to the maximum speed, the controllable shunt switched on, so that a charge of the capacitor can no longer take place and the speed of the machine because of the therefore missing ignition decreases. Either the controllable one is used as a shunt Semiconductor switch itself or an additional thyristor is used.

From the DT-CS 17 64 609 an ignition device is known, in which it should be avoided that a two-stroke internal combustion engine in the wrong direction of rotation can start. Use is also made of a shunt, but not one The aim is to prevent the capacitor from charging, but rather the capacitor in the event of a wrong direction of rotation should discharge before a discharge takes place via the ignition coil.

The subject of the application, unlike these known ignition devices, assumes that the permanent magnet generator, which generates the charging voltage for the ignition capacitor, is to be used at the same time as an alternator for the on-board power supply. In order to achieve sufficient power for this on-board power supply, it is necessary to use a multi-pole generator. Such a multi-pole generator generates an alternating voltage with a number of periods corresponding to the number of pole pairs by selecting one revolution of the cable shaft of the machine. If the ignition capacitor is charged in such a case with a circuit according to DT-OS 19 54 874, then this means that the capacitor is charged again after its discharge at the ignition time from the next positive half-wave of the charging voltage, although ^ ¹ to the next regular ignition and its next discharge at least half a (two-stroke engine) or one and a half (four-stroke engine) revolutions of the generator or the engine crankshaft pass. During this time up to the next regular ignition there is a risk that the capacitor will be erroneously discharged by any interference pulses, but in particular by interference pulses based on the ignition of other cylinders. This would lead to misfires that can seriously affect engine performance.

The object of the invention was therefore to provide an ignition device of the aforementioned type sr ausesta'ien. that when using a permanent magnet generator misfires of the type described can be avoided with at least four poles skill.

This object is achieved according to the invention by the features of the characterizing part of claim I. solved. This solution provides that the capacitor is not activated until immediately before the associated ignition point is charged, while at the same time avoiding it during a time in which a discharge is through Interference pulses must be feared is loaded. Depending on which glitches are used to trigger a Misfiring come into question, either only the last period or its positive half-wave of the Charging AC voltage is used to charge the capacitor, or if glitches are not during this time are to be expected, more than one period of the alternating current lying before the ignition time can also be expected be used for the charge. Advantageous developments of the solution according to the invention are in contained in the subclaims.

The invention and these developments are explained in more detail below with reference to the drawings.

The stator 22a has a permanent magnet 46, cores 47a and 476 which are arranged on opposite sides of the magnet 46 , induction coils 48a and 486 which are respectively wound around the coil cores 47a and 476 and connected in series with one another, a housing 49 containing these elements and a sealing resin 45 filled in the case 49.

With the generator with permanent magnetic field, which is designed as described above, the capacitor charging coils 1 and 2 generate two oscillations of the no-load alternating voltage, as shown in Fig. 4 (a), for each revolution of the generator, ie for each revolution of the engine crankshaft 34a for each revolution of the crankshaft 34a the distributor 22 generates an oscillation of the idle output voltage, as shown by the solid line in FIG. 4 (g) is shown for the time when the positive half-wave of the second oscillation of the capacitor charging coils 1 and 2 is generated.

The mode of operation of the first embodiment shown so far will now be explained. The operation of the various parts of the embodiment which takes place in the course of the rotation of the machine will be explained with reference to Figure 4 which shows the waveforms produced at various points in the execution. When the generated voltage of the capacitor charging coils 1 and 2 begins, in the positive direction at a time fi in FIG. 4 increase, the current shown by the solid line in Fig. 4 (b) flows through the circuit comprising the capacitor charging coil 1, the rectifying diode 3. the primary winding 15a of the transformer 15. the capacitor and the parallel circuit comprising the consists of the diode 7 and the primary winding 9a of the ignition coil 9. This current generates the output shown in Fig. 4 (c) in the secondary winding 156 of the transformer 15, so that the thyristor 14 is opened and therefore the capacitor charging coil 2 is short-circuited by the thyristor 14 , so that the capacitor 6 is charged by the capacitor charging coil 2 becomes ineffective. The capacitor 5 is charged until the final voltage shown in FIG. 4 (e) is reached by charging. Thereafter, the generated voltage of the capacitor charging coils 1 and 2 starts to increase in the negative direction at a time? 2, the current shown by the broken line in Fig. 4 (b). flows through the circuit that contains the capacitor charging coil 1. the earth, the primary winding 16a of the transformer 16, the diode 18 and the capacitor charging coil 1 and the circuit that contains the capacitor charging coil 2, the earth, the primary winding 17a of the transformer 17. the diode 19 causing contains and the capacitor charging coil 2, so that the current shown by the solid line in Figure 4 (d) through the secondary winding 16FR of the transformer 16, the secondary winding 176, respectively flows of the transformer 17, this current that the thyristors 13 and 14 be fueled up at a time _{t 3} , whereby the charge that is stored on the capacitor 5 is discharged over the circuit that contains the thyristor 13, the earth, the development 9a of the ignition coil9, the capacitor and the diode 28 so that in the Secondary winding 96 of the ignition coil 9 a HochspaniHBig feidaziert and on the spark plug 1? em spark ignition.

The function of the diode 7 is to keep the current through the PrinrärwiddungSa of the ignition coil 9 at the za, at the za to increase the Zünddaner of the ignition spark. In the case where the thyristor 14 is turned on, no ignition spark is generated at the spark plug 12 , since then no charge is stored on the capacitor 6.

Thereafter, at a time U, the output of the distributor 22, which is synchronized with the rotation of the generator, as shown by the solid line in Fig. 4 (g), is generated and then, when this output controls the thyristor 13 at the same time, when the generated voltage of the capacitor charging coils 1 and 2 changes from negative to positive, the generated voltage of the capacitor charging coil 1 is short-circuited by the thyristor 13. On the other hand, the generated voltage of the capacitor charging coil 2 is given to the Krens, the rectifier diode 4, the capacitor 6 and the parallel circuit consisting of the diode 8 and the primary winding 10a of the ignition coil 10 and the earth, the capacitor 6, as in Fig-4 (f) is loaded. When the generated voltage of the capacitor charging coils 1 and 2 changes from positive to negative, the current shown by the solid line in Fig. 4 (d) flows in the same manner as in the previous time. in each of the secondary windings of the transformers 16 and 17, so that the thyristors 13 and 14 are controlled to a Zeil h and therefore the charge that is stored on the capacitor 6 via the circuit that the thyristor 14, the earth, the primary winding 10a of the ignition coil 10 and the capacitor 6 is discharged, whereby an ignition spark is generated at the spark plug 12. When this occurs, the device returns to the original conditions so that the above-described sequence of operations is repeated to generate an ignition spark on the spark plugs 11 and 12 in turn. In this first embodiment, the machine stop circuit is designed so that the capacitor charging side connections of the capacitor charging coils 1 and 2 are connected directly via a switch 25 , so that when one of the capacitor charging coils charges the capacitor assigned to it, the other capacitor charging coil is short-circuited. Accordingly, by closing the switch 25, both capacitor charging coils 1 and 2 can be short-circuited and in this way the charging of the capacitors 5 and 6 can be avoided, whereby the rotational movement of the machine is stopped.

F i g. Figure 2 illustrates the second embodiment according to the present invention. This second embodiment differs from the first embodiment in that the transformer 15 is replaced by a distributor 22 ' having coils 48a' and 486 " for producing the output as provided by the The manifold 22 'has the aforementioned distributor core 35, which is shown in Fig. 58 by the solid line, and also has a stator 22a' exactly opposite that on the stator 40 zs the stator, 22a of the manifold 22, as dnrch the broken by two dotted lines is shown when one of the two seats vm circuits AAF both sides of the chain dashed line are shown ailem is used, this Aasüähnmgsform can Sir duck ziHioemncmong rar eme esizyHHunge Mascmne erent.

have a relatively low number of turns, two slow capacitor charging coils 16 and 26, each having a relatively high number of turns, and diodes 54 and 55 connected in parallel with the slow capacitor charging coils 16 and 26, while the fast capacitor charging coil Xa in Series with the slow capacitor charging coil 16 and the fast capacitor charging coil 2a is connected in series with the slow capacitor charging coil 2b, the capacitor charging coils la and 16 connected in series and the capacitor charging coils 2a and 2b being wound on capacitor charging coil cores 41 and 42, respectively, with a coil above the other is arranged in the same position on the stator 40, as shown in Fig. 6A. Furthermore, the circuit of FIG. 3 resistors 56 and 57, poorly conductive elements (ie thermistors) 58 and 59 with a negative resistance characteristic, which prevent the output of the transformers 16 and 17 from changing due to changes in temperature.

The third embodiment operates in the following way: when the machine is operating at low speed, the output generated from all capacitor charging coils la, ib. 2a and 2b is low. However, due to a relatively small delay in the generated voltage of the slow capacitor charging coils \ b and 2b due to the impedances of the capacitor charging coils la, Xb, 2a and 2b due to their inductances and the short-circuiting of the counter voltages by the diodes 54 and 55, the charges Output of the series-connected two capacitor charging coils la and Xb (or 2a and 2b) the capacitor 5 (or 6) sufficient. On the other hand, while the machine is working at high speed, there is a relatively large delay in the generated voltage of the slow capacitor charging coils Xb and 2b due to the impedances of the slow capacitor charging coils 16 and 2b by their inductance / s and the short-circuiting of the counter voltages by the diodes 54 and 55 generated so that practically the entire output of the fast capacitor charging coils la and 2a, with which the diodes 54 and 55 are not connected in parallel, to the capacitors 5 and 6 through the diodes 54 and 55, so that in this way the capacitors 5 and 6 can be loaded. Here, the impedance of the capacitor charging coils la, 16, 2a and 26 increases in proportion to the square of the number of turns in the corresponding coils and in proportion to the increase in the number of revolutions of the machine, so that the internal voltage drop during operation of the machine at high speed the respective capacitor charging coils Xa, 16, 2a and 26, with the resulting drop in the capacitor charge voltage increases with the in parallel with the slow capacitor charging coils Xb and 2b of the series-connected capacitor charging coils la, 16 and 2, 26 connected during operation at high speed Diodes 54 raid 55 the capacitor {oder6} is charged only rait the output lter fast capacitor charging coil ta (or 2a) through the diode 54 (or 55), as explained above. While the open circuit voltage that is generated in the fast capacitor charging coil la (or 2a) decreases in relation to the number of turns in comparison with iem FaH, where the two capacitor charging coils la and 16 (or Za and 26J are connected in series).

consequently, its impedance decreases in proportion to the square of the number of turns and also the voltage generated by the capacitor charging coils generally increases in proportion to the increase in the Machine revolutions. Therefore, the voltage on capacitor 5 (or 6) during the Machine operation at high speed will eventually be increased. Consequently, the tension on the Capacitors 5 and 6 during the operation of the

ίο Medium and high speed machine can be made constant.

Furthermore, since the series-connected capacitor charging coils Xa and 16 as well as 2a and 26 are wound separately on different capacitor charging coil cores 41 and 42, the counter magnetomotive forces that are generated by the slower capacitor charging coils 16 and 26, especially during operation of the machine at high speed, reduce the with diodes 54 and 55 in parallel

are connected, largely the magnetic flux that runs through the capacitor charging coil cores 41 and 42. However, since the fast capacitor charging coils Xa and 2a for charging the capacitors 5 and 6 have correspondingly separated capacitor charging coils

ne 41 and 42 are wound and there the capacitor charging cores 41 and 42 on which the fast Capacitor charging coils la and 2a for charging the capacitors 5 and 6 are wound, furthermore with slow capacitor charging coils 16 and 26 are provided which are wound on these cores so that during of the charging process of the fast capacitor charging coil la or 2a, the slow capacitor charging coil 16 or 26. which is assigned to the other cylinder is short-circuited by the thyristor 13 or 14, wherein

3 £ always an essentially constant counter magnetomotive force Force is generated regardless of the number of machine revolutions, the voltage on capacitors 5 and 6 during the operation of the machine in the middle and high Speed range can be made more uniform.

In this embodiment, the cores 41 and Side by side, as shown in FIG. 6B, instead of a layer structure.

uses those circles that are on top of the dash-dotted line in FIG. 8 are located.

F i g. 9 shows the sixth embodiment of the present invention in which the thyristors 13 'and 14 'for deactivating the capacitor charging half-waves from the capacitor charging coils 1 and 2 corresponding to the connections of the capacitors 5 and 6 are connected. This embodiment can can also be adapted for use in a single cylinder machine by adding only those Circles are used which are above the dash-dotted line in FIG. 9 are located.

In the case indicated by the dashed lines in FIG. 8 and 9 The fifth and sixth embodiments shown can furthermore be the primary winding 17a of the transformer 17 via the connections of the capacitor charging coil 2 through the diode 19 and the secondary winding 176 of the Transformer 17 can be connected to the ignition electrode of the thyristor 13, so that the thyristor 13 is controlled by the output of the transformers 16 and 17, respectively. In this way the guideline constants of the charging circuit for the capacitor 5 equal to those of the charging circuit for the capacitor 6 can be made so that any imbalance between the voltages of capacitors 5 and 6 and is switched off in the firing order.

Fig. 10 shows the seventh embodiment of the present invention. This embodiment is different differs from the first embodiment of FIG. 1 in that instead of the transformer 15 and the diode 28, a diode 50 connected in series with the primary winding 9a of the ignition coil 9 and the The firing circuit of the thyristor 14 is added to the charging circuit for the capacitor this embodiment is substantially the same as that of the first embodiment. Further In this seventh embodiment, the ignition control means for the thyristors 13 and 14 den single transformer 16, while both thyristors 13 and 14 to the output of the secondary side of the Transformer 16 can be controlled.

It can therefore be seen that in the first to seventh embodiments described so far, the ignition control means for discharging the capacitors 5 and 6 comprises one or two transformers 16 and 17 each consisting of a current converter. Therefore, as the number of revolutions of the engine increases, the output current value increases as shown by the broken line in FIG. 4 (d) shows that the time during which the thyristors 13 and 14 are conductive has increased. On the other hand, when high machine speed is reached, the amount of increase in the output current value of the transformers 16 and 17 decreases due to the magnetic saturation of the transformer cores and the inductances of windings 16a, 166.17a and 176. so that the time during which thyristors 13 and 14 are switched on becomes substantially constant. Accordingly, the relationship shown in Fig. 11 between the number N of revolutions of the engine and the firing order of the spark plugs 11 and tZ is obtained, which gives an excellent pre-ignition characteristic 17 form, are obtained, the thyristors 13 and 14 grazing controlled by the Assgang «nasty voltage converter.

Further, in addition to the ignition control means described in the above-described first to seventh Embodiment used, the outlet of the manifold 22 is used for the same purpose as used in the eighth embodiment shown in FIG. In other words is, as shown by the dash-dotted line in Fig.5B, a second distributor core 35a on the Center piece 34 is provided in a position so that the

ίο distributor core 35 is guided by about 90 °, the Distributor 22 generates output signals as shown by the solid and dashed lines in Figure 4 (g) while the manifold 22 'produces output signals as differentiated by the two

) 5 dash-dotted lines are shown in Figure 4 (g), the thyristors 13 and 14 being opened in response to these outputs in order to discharge the capacitor 5 without using the transformer 16 or the like. In this eighth embodiment, the series-connected fast capacitor charging coil la (2a) and the slow capacitor charging coil \ b (2b) are wound on the same capacitor charging coil core, while the diode 54 (55) is connected in parallel with the slow capacitor charging coil \ b (2b) .

In this way, the voltage on each of the capacitors 5 and 6 during operation of the Medium and high speed machine equalized. This embodiment can also be used for can be adapted to use with a single cylinder machine by using one of the two circuits above or below the dash-dotted line in FIG. 12 is used.

Furthermore, while in the first to eighth embodiments described above the permanent magnetic field generator was designed with four poles, it is also possible to use multi-pole generators with more than four poles, that is, six-pole and eight-pole types. For example, in the ninth embodiment shown in FIG. 13, a six-pole generator is used for the ignition device for operating a two-cylinder engine. Fig. 14 shows the waveforms generated at various points in this igniter.

not turned on At a time 7}, the distributor core 35a causes the signal coil 48c of the stator 22a of the distributor 22 to perform the steps shown in FIG. 30 (d) generated voltage, whereby the thyristor 13 is turned on and thereby the charge stored on the capacitor 5 is discharged through the circuit containing the thyristor 13, the ground and the primary winding 9a of the ignition coil 9, creating a high voltage in the secondary winding 96 of the ignition coil 9 and thereby an ignition spark at ι ο the spark plug 11 is generated. When the machine speed reaches a predetermined number of revolutions, a sufficiently large output voltage is generated from the secondary winding 166 of the transformer 16 and accordingly the thyristor 13 is turned on at the time T ₂ , as shown by the chain line in Fig. 30 (a) The result is a gradual progression of the firing sequence from toe 7} to T ₂ , which means that the machine works better. In this case, while at the time T ₂ the signals are simultaneously given to the other thyristors 14 and 14 'in addition to the thyristor 13, there is no previously stored charge in the capacitors 6 and 6' and therefore no spark on the spark plugs 12 and 14 12 '.

If at a time Ta the distributor cores 356 and 35c come into alignment with the stators 22a and 22a "of the distributors 22 and 22", the signal coils 48c and 48c "generate signal voltages, ίο that the generated voltages of the capacitor charging coils 1 and 2 'through the Thyristors 13 and 14 'are then short-circuited. The voltage generated by the capacitor charging coil 2 then causes a current to flow through the circuit consisting of the coil 2, the diode 4, the capacitor 6 and the parallel circuit comprising the diode 8 and the primary winding 10a of the ignition coil 10, whereby the capacitor 6 is charged up to a voltage shown by the broken line in Fig. 30 (b) On the other hand, when the machine is operated at low speed, the thyristor 14 is turned on at a time Tf, controlled by the output voltage from the signal coil 48c ″ of the stator 22a ′ of the distributor 22 ′, while the machine is operating at medium and high speed The thyristor 14 is turned on _{by the secondary output voltage of the transformer 17 at a time Γ 5} , whereby a high voltage is induced in the secondary winding 106 of the ignition coil 10 and an ignition spark is generated at the spark plug 12 as a result.

Similarly, the capacitor b 'starts to charge at a time Ti as shown by the broken line in Fig. 30 (c), the capacitor charging coils 1 and 2 being short-circuited by the signal voltages of the distributors 22 and 22' through the thyristors 13 and 14 . Thereafter, an ignition spark is generated at the spark plug 12 'at a time Tg (for medium and high speed) or T _{9 (for low speed).}

After that, at a time Γιο = Γι the thyristors 14 and 14 'are controlled by the signal voltages of the distribution lines 22' and 22 "and therefore the capacitor discharge coils 2 and 2 'short-circuited.

In the manner described above, the required sparks are sequentially sent to the Spark plugs 11, 12 and 12 'generated at intervals of 120 degrees.

These signal coils are grouped in pairs, each pair comprising two coils wound on the various cores and connected in series. In other words, the signal coil 48a is in series with the signal coil 486 ', the signal coil 48a' on the other hand with the signal coil 486 "and the signal coil 48a" with the signal coil 486. The signal coils 48a and 486 ', 48a' and 486 "and 48a" and 486 are correspondingly connected to thyristors 13, 14 and 14 'with their respective ignition electrodes.

Internal combustion engine the danger that a rich mixture, which was previously fed into the cylinders, is ignited by the ignition sparks, which happens near the bottom dead center, the generated flame is ejected through the exhaust pipe and causes a fire. The same is true when the rotation of the machine is reversed. Consequently, the operational safety of internal combustion engines, in particular of two-cylinder engines, can be improved with the independent ignition device according to the present invention, in which the ignition coils 9, 10, 10 'are correspondingly connected to the spark plugs 11, 12, 12' so that the ignition sparks only occur in the region of top dead center during forward running of the machine and which is further arranged so that the occurrence of any ignition sparks is avoided when the machine is rotated in the reverse direction.

Thus, the manifold 22 and 22 ', the signal voltages shown by the solid lines in Figure 4 (h) ao generate, two manifold cores 35b and 35c on the central piece 34 at a location immediately upstream of the distributor core 35a and at another Place which is exactly opposite this point, can be attached, as the corresponding dash-dotted lines in FIG. 5B show. In order that the distributors 16 and 22 'can generate the signal voltages indicated by the solid lines in FIGS. 30 (h) and 32 (g), respectively, it is only necessary to have three distributor cores 35c /. 35e and 35 / "on the bell-shaped flywheel body 31 immediately in front of the distributor cores 35b and 35cin Fig. 29A and at a distance of 120 degrees from these locations.

On the other hand, in the arrangements shown in Figs. 15.16.17, 20 and 22 are shown, in which the capacitor charging coils 1 and 2 generate voltages of opposite polarity, the distributors 22 and 22 'are designed so that their corresponding signal voltages, as shown by the solid lines in Fig. 14 (f _t ) and 14 (f ₂ ) shown immediately before the capacitor charging coils 1 and 2 produce their respective half-wave outputs for charging the capacitors 5 and 6, avoiding that the machine changes its direction of rotation. In this case, as shown by the dash-dotted lines in Fig. 18, three distributor cores 35a. 35 £> and 35c are arranged on the center piece 34 at a point immediately in front of the distributor core 35 and in front of and behind this point offset by 120 degrees therefrom, the distributors 22 and 22 'being shown by the solid lines in FIG. 14 (fi) and 14 (f ₂ ) . Furthermore , in the case of the internally rotating generator as shown in FIGS. 23A, 23B and 23C, the rotor 35 'of the manifolds 22 and 22' are similarly provided with additional pawls or lugs at suitable locations thereof, the manifolds 22 and 22 "being indicated by the solid lines in Fig. 14 (f ,) and 14Jf ₂ ).

In the arrangements shown in FIGS. 2, 3, 8, 9, 12, 25, 28, 31 and 3760, in which the center! have distributors 22 and 22 ″ for generating downward signals, the connection direction of the signal coils 48a, 486.48a and 486 ′ of the distributors 22 can be reversed 22 * or the polarity of the permanent magnet 4665 can be reversed, so that, as indicated by the dashed lines in FIG. 14 (f,) rad Wßä shown, the Verteier ffld 22 * their corresponding negative half-waves immediately before the generation of the undesired charging half-waves for the capacitors 5 and 6 and positive half-waves immediately after the generation of these undesired charging half-waves by the capacitor charging coils 1, la, 2 2a produce. in this way, it is only necessary that the manifolds 22 and 22 'produce an oscillation of its output, that is, when a located inside rotating generator as g in F i.! 8 is shown, is used that both of the two distributor cores that follow one another are mounted on the middle piece, with only one distributor core mounted between the undesired ones Half-waves of the voltages generated by the capacitor charging coils 1, la. 2, 2a can be short-circuited to charge the capacitors 5 and 6, while avoiding that the machine is rotated in the opposite direction. In the arrangement in which the distributors 22, 22 ' and 22 " generate the signal voltages as shown by the solid lines in FIGS. 14 (fi) and 14 (f ₂ ), while there is a risk that dependent from the selection of the pre-ignition characteristic and the control of the output voltages of the distributors 22, 22 ' and 22 " in the arrangement, a delay in the output voltage of the transformers 16, 17 and 17' at low machine speed, the discharge time of the capacitors 5, 6 and 6 'through them Outputs can affect in such a way that the times at which the output voltages of the distributors 22, 22 ' and 22 "are given to the thyristors 13 , 14 and 14' , overlap, with the pre-ignition characteristic being worsened at low engine speed Generation of the output voltages shown by the solid lines in FIGS. 14 (fj) and 14 (f ₂ ) by the distributors 22. 22 and 22 "has the effect that. While the output voltages of the transformers 16, 17 and 17 'are present during the forward movement of the machine, the distributors 22. 22' and 22 " do not produce half-wave output voltages that drive the thyristors 13, 14 and 14 ' on, which makes an excellent output even at low machine speeds Furthermore, when the machine is rotated in the reverse direction, the thyristors 13, 14 and 14 ' conduct at the point in time when the voltages generated by the capacitor charging coils 1.2 and 2' rise in the direction that the capacitors 5,6 and 6 do 'charges, which lowers the charge stored on capacitors 5, 6 and 6'.

In the in the Fig.2. 3, 8, 9, 12, 25, 28, 31 and 37, practically the same effect as mentioned above can be obtained by replacing the thyristors 13, 13 ', 14, 14' with bidirectional thyristors 13a, 13a ', 14a and 14a 'as shown in Fig. 39 and by causing the manifolds 22, 22' and 22 "to appear at the points of the dashed lines in Figs. 14 (fi) and 14 (fj) and Fig. 30 (g) Output voltages or, alternatively, the output voltages with reverse polarity with respect to the voltages shown by the dashed line generate a In this case the connections of the signal coils 48a, 48a, 48a ". 48h 4Sb ¹ , 486 ". 48c 48c" of the distributors 22, 22 'and 22 "can be made with these bidirectional thyristors in any way, there being no risk of error in making these connections

A similar result can be obtained without using the

Bidirectional thyristors I3a, i3a ', 14a and 14a' are obtained when the output voltages of the signal circuits 48,7,48. / ', 48 </ ". 486, 48b'. 48b". 48c, 48c ^{1 of} the distributors 22, 22 'and 22 "are given to the thyristors 13, 13', 14, 14" after they have undergone full-wave rectification by full-wave rectifiers 71, 72 and 72 ', as shown in FIG. 40 shown have been subjected.

In the embodiments shown in Figs. 12, 31 and 34, in which all required Control signals for the thyristors 13, 14, 14 'are generated by the distributors 22, 22', 22 ", with the in Referring to the case illustrated in the waveform diagram of Fig. 4, where the machine in is rotated in the correct direction, the thyristors 13 and 14 by the positive half-wave voltage, by the solid lines in F i g. 4 (h) can be turned on so that the Charges stored on the capacitors 5 and 6 correspondingly via the primary windings 9a. 10a the ignition coils 9 and 10 are discharged, whereby ignition sparks are generated on the spark plugs 11 and 12 whereas when the machine is in reverse Direction is operated, the thyristors 13 and 14 by the half-waves of opposite polarity with respect to the voltage shown by the solid line in Fig. 4 (h) (reverse polarity occurs when the machine reverses its direction of rotation) so that the discharging of the Capacitors 5 and 6 can be made ineffective by the capacitor charging coils 1 and 2. With In other words, with the single distributor core and an oscillation of the output voltages of the distributors 22 and 22 'can perform the dual functions of causing ignition and preventing Rotating the machine in the wrong direction.

In the circuit shown in Fig. 34, in which the manifolds 22 and 22 'generate a plurality of continuous signals as shown in Figs. 35 (b) and 35 (c), respectively, it is possible to use auxiliary poles 64a. 646 and 64c to be mounted on the flywheel body 31 near the permanent magnet 32 / and further to arrange auxiliary poles 65a and 65b on the pole piece 33 / as shown by the chain lines in Fig. 36A. wherein the distributors 22 and 22 'a plurality of continuous signals, as shown in Fig. 35 (d) and 35 (e) are shown, so that the charging of the capacitor 5 by the capacitor charging coils la and 16 after reversing the direction of rotation the machine can be made ineffective, thereby preventing continued operation of the machine in the reverse direction.

Fig.41 shows the 21 th embodiment of the present invention, in which the fast capacitor charging coil \ a and the slow capacitor charging coil 16 are located to each other via the diodes 3a and 36 in parallel circuit. The generated waveforms of the voltage of the distributor 22 are indicated by the solid and dashed lines in FIG. 42 {d) while the generated waveforms for the voltage of the capacitor charging coils Ia and 16.vue are shown in FIGS. 42 (a) and 42 (b) with the phase of the voltage of the fast Kondensa torladespule la generated voltage of the slow capacitor charging coil \ generated b are advanced by 60 degrees, which is less than 180 degrees, when za a time 71 in F i g. 42 the generated voltage of the fast capacitor charging coil la rises in the direction that charges the capacitor, the capacitor is charged by the circuit that contains the fast capacitor charging coil la, the diode 3a, the earth and the parallel circuit that contains the diode 7 and the primary winding 9a the ignition coil 9 has. Thereafter, at a time T _1, the voltage generated by the slow capacitor charging coil 16 charges the capacitor in a similar manner through the diode 36. Consequently, as shown by the dashed line in Fig. 42 (a), the capacitor

ίο loaded. Thereafter, at a time Ts, the voltage shown in FIG. 42 (d) is generated in the distributor 42, this voltage being applied to the ignition electrode of the thyristor 13 via the diode 23, whereby the thyristor 13 is turned on. When this occurs, the charge stored on the capacitor 5 is quickly discharged via the circuit comprising the thyristor 13, the earth and ¹ the primary winding 9a of the ignition coil 9, thereby inducing a high voltage in the secondary winding 96 of the ignition coil 9 and thereby producing an ignition spark the spark plug 11 is caused. Thereafter, at a time T _5, the voltage shown by the solid line in FIG. 42 (d) is generated in the distributor 22, so that the second oscillation of the generated voltage of the fast capacitor charging coil la is short-circuited by the thyristor 13 being turned on , whereby the charging of the capacitor 5 is prevented. In this case, the line through the thyristor 13 is not attenuated, while the voltage generated by the fast capacitor charging coil la remains in the direction that charges the capacitor. Therefore, if at a time 7 " ₅ the generated voltage of the slow capacitor charging coil 16 rises in the direction that charges the capacitor, this voltage is simultaneously short-circuited by the thyristor 13, whereby the charging of the capacitor 5 is prevented. In this way, an ignition spark is generated generated at the spark plug 11 for each rotation of the crankshaft during the forward rotation of the engine. In this embodiment, the slow condensation

Satorladespule 16 also has a large number of turns and a high inductance with the result, that the rise in the generated voltage of the slow capacitor charging coil 16 is delayed in stages will as the number of revolutions of the machine

increases. However, since the thyristor 13 remains in the conductive state during the generated voltage of the fast capacitor charging coil la remains in the direction that can charge the capacitor undesired capacitor charging half-waves of the slow capacitor charging coil 16 inevitably ineffective be made.

On the other hand, if the direction of rotation of the machine is reversed, the thyristor 13 will dorefc the output voltages (opposite polarity

If then the generated Voltage of the capacitor charging coils 1.1 a, I ft 2.2a, 26, 2 'becomes higher than the Zener voltage of the Zener diode 95, the Zener diode 95 is made conductive, whereby the Thyristor% is turned on, so that the charge stored on capacitor 97 through the The ignition electrode and the cathode of the thyristors 13, 14, 14 ', the thyristor% and the resistor 93 are discharged is made, the thyristors 13,14,14 'made conductive will. In this way, the charge stored on the capacitor 5, 6, 6 'is discharged, whereby a High voltage in the secondary winding 96, 106, 106 'of the ignition coils 9, 10, 10' is induced and thereby a Spark at the spark plug 11, 12, 12 'is generated. Even with the phase reversal loops 98, a excellent preignition characteristics can be obtained as in the case where the transformers, i.e. H. Current or Voltage converters can be used.

Further, in the embodiments in which the generated outputs of the capacitor charging coils 1 and 2 have an opposite polarity of 180Gn.d have, as is the case for an ignition device for is a two-cylinder machine that uses a six-pole generator with a permanent magnetic field is, as shown in Fig.52, a thyristor 13 'via diodes 13a' and 136 'with the connections of the Capacitor charging coils 1 and 2 are connected so that the thyristor 13 'by the output voltage of the Means for generating the suppression signal, d. H. the distributor 22, 22 'etc. is opened, with the Charging the capacitors 5 and 6 by the undesired capacitor charging half-waves of the capacitor charging coils is suppressed.

While in the embodiments of the invention described above, the diodes 7.8 and 8 'are respectively connected to the primary windings 9a, 10a and 10a' of the ignition coils 9.10 and 10 'for the purpose of achieving a longer arc duration on the spark plugs 11, 12 and 12' can, as shown in FIG. 53 shown, the diode 7 (8, 8 ') in anti-parallel connection with the connections of the thyristor 13 (14, 14') are connected, so that a closed circuit through the capacitor (6, 6 '), the diode / ( 6, 8 ') and the primary winding 9a (10a. IOa') of the ignition coil 9 (10, 10 ') is formed. As a result, when the thyristor 13 (14, 14 ') is turned on, the charge on the capacitor 5 (6, 6') is discharged through the circuit that controls the thyristor 13 (14, 14 ') and the primary winding 9a (10a, 10aV of the Ignition coil 9 (10, 10 '), the capacitor 5 (6,6') being charged in the opposite direction 9 (10, 10 ') and the diode 7 (8, 8'). In this way · the capacitor (6, 6 ') can be charged and discharged alternately, by means of the stored charge, so that a current alternately flows from both the positive and the negative direction into the primary winding 9a (10a, 10aV of the ignition coil 9 (10, 10 ') to ensure a longer arc duration on the spark plugs 11 (12, 12') ) to ensure.
