Germany Application June 12, 1931, Serial No. 543,970, and in Germany June 13, 1930 Claims. (CL 123-184) The present invention relates to a starting ignition device for multicylinder internal combustion e ines.
In order to start internal combustion engines 5 by ignition, the working ignition coil is with battery ignition, operated in known manner by a make and break device operated by hand-or more usually electrically driven, whereby the ignition coil is either changed over from its working make and break device to a starting make and break device or the starting make and break device is connected in parallel to the working make and break device. In the first case there is the possibility, it is true, of effecting ignition in all positions in which the engine is at a standstill,
but the danger of back-kickingis, of course considerable. In the second case in which the working make and break device operates the starting make and break device, danger of back-kicking is eliminated in as far as the duration ofopening of the working make and break device only lasts until no spark can pass over from the distributor electrode to the segment succeeding the correct segment. It must, however, be taken into consideration that a spark can only be produced within a range predetermined by the working .make and break device after the dead centre of the motor. It is desirable to keep this range comparatively small, more particularly with multicylinder motors in order to obtain suflicient closing time for the working ignitionand as short as possible distributor segments. The disadvantages mentioned are eliminated according to the invention in that during the starting process the running ignition coil can transmit a series of sparks to the running electrode and a special starting ignition coil can transmit a series of sparks to the knownstarting electrode of the distributor. The invention is illustrated in the drawings by several examples in which:-- 1
Figure 1 shows the connection of a starting ignition device with a mechanical make and break device for starting.
Figure 2 shows a trembler coil.
Figure 3 shows this second connection in which the trembler is controlled by the primary coil or the starting ignition coil. r
Figure 4 is a connection with atrembler according to Figure 2 for alternately making and breaking the ignition coils. I Figure 5 is a connection with -a trembler ac cording to Figure 3 with intermittent interruption second connection with a oithe ignition coils.
Figure 6 shows a special slowing dowfiposition of the motorand the distributor.
In Fig. 1 a battery 1 is earthed at one pole and the other pole is connected to one contact of a unipolar ignition switch 2. One end of each of the two ignition coils 3 and 4, one at high tension and the other at low tension, are connected to the other contact of thisswitch. The other end of the prirnarywindingb, 6 is connected to each of two fixed contacts '7, 8 of a mechanically (Fig. l) or the secondary coil 13 is connected through-the a lead 2'7 to the working electrode 14 of the dis tributor 15 whilst the other end of the secondary coil 16 is connected through the lead 28 to a starting electrode 17 of the distributor. This starting electrode follows the working electrode through an angle determined by the number of cylinders and the required starting range.
The operation of the device is as follows:- 8
After a multi-cylinder internal combustion engine has been stoppedone piston at least is always located past the upper dead centre so that its cylinder contains inflammable mixture. The piston A is at rest in this position (Fig. 1) and the working electrode 14' is thereby located in iront'of the distributor segment 18 belonging to this piston. The mixture in .the cylinder can therefore be ignited directly by a spark from the working coil and the motor thereby put into op- .eration. But it sometimes happens that the working electrode lafcomes to rest in front of a segment the respective piston of. which has been brought torest before the top dead centre. This case is shown in Fig. 6 and it is assumed that it is a five-cylinder motor. The working electrode 14 stands in front of the segment .30 which belongs to the piston B which stands before the top dead centre. There could be no starting with the working coil alone in this position, as the make ,and break device 9 must have been closed again for a long time because otherwise a spark could arise in the cylinder 13 and back-kicking of the engine thereby caused. It is however possible to .start the engine by the starting electrode 17 with the present arrangement. The starting electrode l'lis so near to the segment 18, which belongs to the piston A which as a matter of fact lies at a fair distance from the top dead centre, that ignition can take'place in the cylinder A. The spark no is produced by means of the starting coil 4 and the auxiliary make and break device (8, No
' bler coil 25 is connected on one side to the spring 20 and on the other side is earthed through the starting press button 24. The lead from theworking coil 5 to the contact *1 is also operated by the press button 24 so that the starting coil does not lie permanently parallel to the working coil when the trembler has stopped. The trembler simultaneously makes and breaks the two primary circuits of the ignition coils. Y
The construction according to Fig. 3 only differs Irom that according to Fig. 2 in that the primary winding oi the starting coil acts also as trembler coil to the starting coil.
The construction according to Fig. 4 shows an arrangement wherein a trembler is provided for alternately switching on the primary coils 5 and 6. The flxed contact 7 of the working coil is separated from the contact 23 of the trembler armature when the trembler is at rest whilst the fixed contact 8 of the starting coil contacts with the contact 22 of the trembler armature. As soon as the press button 26 closes the circuit of the trembler coil 25, the spring 20 is drawn towards the core of the trembler and the contact 7-23 is closed and the contact 22, 81s opened. The press button 24 with the double contact member can here be omitted because'the coil is cut oil from the trembler when the trembler is stopped. The construction according to Fig. 3 can of course be so made that the primary coil circuits .are alternately broken. The corresponding connection is shown in Fig. 5.
