Definitions

  • the present invention relates to an emergency ignition device for internal combustion engine.
  • the engines of motor vehicles are generally of the spark-ignition type and for this purpose they have, with the exception of diesel engines, one spark plug per cylinder, these plugs being supplied at high voltage from the secondary winding d 'An ignition coil, via the rotor of a distributor. It is known that these ignition devices give rise, in the long run, to a certain number of failures which may be due to the breaker, to the capacitor, to the coil or, if they exist, to the electronic modules of the broken down vehicle. The troubleshooting of these engines is traditionally carried out by professionals but in most cases there is no other solution than to tow the vehicle to a repair shop.
  • the present invention aims to remedy these drawbacks by providing an emergency ignition device with a low cost price and making it possible to troubleshoot a motor vehicle very easily.
  • this emergency ignition device for thermal engines with controlled ignition, the ignition circuit comprising an ignition coil to the secondary winding of which the spark plugs of the various cylinders of the engine are connected, comprising an oscillator connected to a stabilized power supply, the output of which is connected to a power transistor connected in series with the primary winding of the ignition coil, characterized in that it comprises a normally open control switch which is closed by at the same time as the starter is actuated, means for modifying the operating frequency of the oscillator depending on whether the control switch is open or closed, so that the oscillator operates at a relatively low first frequency as long as the control switch is closed and at a second higher frequency than the previous one when the switch is open, and a timing circuit connected to the oscill the control switch so as to inhibit the operation of the oscillator for a predetermined period of time after the instant of the closing of the control switch and to then let the oscillator operate at the first relatively low frequency as long as the control switch is kept closed, that is to say as long as the starter is operated to turn
  • the emergency ignition device offers the advantage that it makes it possible to start an engine regardless of the faults which have appeared in the normal ignition circuit.
  • FIG 2 which shows in detail the diagram of an embodiment of the device indicated schematically in Figure 1,
  • the control switch 1 which is normally open, is connected between the positive pole of a circuit stabilized supply 7, and ground, on the one hand by a resistor 8 and on the other hand by a capacitor 9 and two resistors 11, 12 in series.
  • the junction point between the resistors 11, 12 is connected to the base of a transistor 13 whose emitter is connected to the ground and the collector is connected on the one hand to the positive pole of the power supply, by a resistor 14, and on the other hand 3 a terminal "6" of an integrated circuit 15 of the L11 556 type manufactured by National Semiconductors.
  • the integrated circuit 15 assumes the functions of timing, switching and oscillation.
  • the collector of transistor 13 is also connected to ground by a capacitor 16.
  • Terminal "5" of the integrated circuit 15 is connected, by a resistor 17, b to the base of a transistor 18 whose emitter is connected to ground and whose collector is connected on the one hand to the positive pole of the power supply, by a resistor 19, and on the other hand the terminal "10" of the integrated circuit 15.
  • control switch 1 is also connected, by a resistor 21, to the base of a transistor 22 which is connected to ground by a capacitor 23.
  • the emitter of this transistor 22 is connected to ground while its collector is connected to terminal "12" of the integrated circuit 15; by a capacitor 23, and also at terminal 13, by a resistor 24, this terminal 13 also being connected to the positive pole of the power supply by a resistor 25.
  • the collector of transistor 22 is also connected to ground by a capacitor 26
  • Terminal 11 of the integrated circuit 15 is connected to ground by a capacitor 27.
  • the output terminal 9 of the integrated circuit 15 is connected, by a resistor 28, to the base of a transistor 29 whose collector is connected to the positive pole of the battery, by a resistor 31 and whose emitter is connected to the base of the power transistor 4.
  • the user closes the control switch 1 at the same time as he actuates the starter.
  • This has the effect of applying to the integrated circuit 15, by the transistor 13, a short duration pulse, this pulse being transmitted to the terminal. "6" of the integrated circuit 15.
  • This results in a status signal at the terminal "5" which switches the transistor 18 to the conducting state and the signal from the collector thereof which is applied to the terminal "10 "of the integrated circuit 15, causes blocking of the part constituting the oscillator.
  • the control switch 1 As soon as the control switch 1 is closed, it suppresses the emission of the alternating signal to the terminal Sor- tie "9" of the integrated circuit 15.
  • the control switch 1 actuates the starter, the engine therefore runs for a certain period of time without the ignition coil 5 being traversed by an alternating current.
  • the inhibition signal applied to terminal "10" disappears and the oscillator is restarted. However, its frequency is then lowered compared to the initial frequency, owing to the fact that the transistor 22 has been made conductive as a result of the closing of the switch 1. This has the effect of shorting the capacitor 26 and lower the frequency of the oscillator. For example if the initial frequency is 200 Hz, the frequency then supplied to the output terminal "9" falls to 100 Hz. The frequency signal 100Hz is then applied, by the transistor 29, to the power transistor 4 and then, after amplification, to the ignition coil 5 and to the spark plugs 6. This low frequency signal is applied until the engine starts. At this time the driver of the vehicle releases the control switch 1 so that the oscillator then operates at the higher frequency of 200 Hz which is better suited to the normal engine speed, the low frequency of 100 Hz being suitable for the engine launch period.
  • the device according to the invention can be used either with the ignition coil 5 of the vehicle or with its own coil.
  • Switches 34 and 35 allow the electronic ignition 33, the conventional ignition 32 or the ignition device to be put into service. rescue according to the invention.
  • the switch 34 is connected between the base of the transistor 29 and on the one hand the resistor 28 and on the other hand a transistor forming part of the electronic ignition 33.
  • the switch of the conventional ignition device 32 is connected from on the one hand to the transistor of the electronic ignition 33 and on the other hand to the switch 35 which is connected between the power transistor 4 and the ignition coil 5.
