  • FIG. 1 is an illustration of the general structure of a control arrangement according to the invention.
  • FIG. 2 is a schematic circuit diagram of the illustrated arrangement.
  • both bustion engine (not shown) having an ignition distributor switch 10 and interrupter means contained in the distributor housing (or equivalent control pulse generator means) comprises an ignition coil assembly 11 and, control circuit means described further below and including transistors 12 and 13, the whole control arrangement being arranged within a housing 15 attached to the housing of the ignition coil 11 by means of a strap 14.
  • the ignition coil assembly 11 is equipped with a primary winding 20 made of a small number of turns of rather thick wire :and a secondary winding 21 which is preferably mounted on a common iron core 22.
  • the secondary winding serves to produce a high voltage igni tion pulse every time when the flow of current through the primary winding 26 is interrupted, and is made of rather thin wire in about 200 times as many turns as the primary winding.
  • One end of each of the windings is connected via a' common terminal 23 with electrical ground and with the minus terminal of a source of continuous electric energy, e.g. a six volt battery 24.
  • the other end of the secondary winding 21 is connected via a plug 25 and a cable 26 leading to the distributor 10, or more particularly with the rotary arm 27 thereof which is adapted to be driven through the projecting shaft 28 at a speed equal to one-half of the crank shaft speed of the engine.
  • the ignition pulses are deliveredsequentially to the four spark plugs of the engines, one
  • the second end of the primary winding 29 is connected with a terminal 32 mounted in the insulating lid 31 of the coil assembly 11, and the terminal 32 is connected by a line 33 with a terminal 34 of the control circuit arrangement 15 described further below.
  • two transistors 12 and 13 have their emitter-collector circuits connected in series with each other between the above mentioned terminal 34 and a terminal 35 which latter is connected via a line 36 with the positive terminal of the battery 24.
  • the base electrode of the transistor 12 is connected in accordance with the invention via' a rectifier 40 with a terminal 39 connected via line 39 with the movable interrupter contact 38.
  • the interrupter contact 38 is actuated in conventional manner by a rotary cam member 50 driven in conventional manner by the engine via its shaft 28 so as to periodically move the contact 38 into and out of engagement with the stationary contact 51.
  • the arrangement 28, 38, 50, 51 constitutesfa control pulse generator because it is in circuit with the battery 24.
  • control pulses referred to further below may also be generated by different means than the above mentioned and illustrated interrupter, e.g. by a four-pole alternating current generator driven in synchronism with the distributor shaft 28 and furnishing four brief control pulses per revolution.
  • the above mentioned rectifier 40 is arranged in such a manner that theemitter-base current of the transistor 12 is enabled to pass through the rectifier 4t) withou encountering an appreciable resistance.
  • a second rectifier 41 is connected. in the same manner between the base electrode of the transistor 13 and the above mentioned terminal 39.
  • Patented Jan 26, 1 965 s ea /o5 In operation the above described arrangement functions as follows: As long as or whenever the cam 50 is in a position in which the movable interrupter contact 38 is in engagement with the stationary contact 51 an emitter-base current flows through each of the transistors 12 and 13 and via the rectifiers 40 and 41, the magnitude of this current being limited by the protective resistors 42 and 43, respectively. By these emitter-base currents the transistors 12 and 13 are rendered conductive. Under these conditions a strong current is permitted to flow across the emitter-collector circuits of the transistors 12 and 13 and through the primary winding 26 whereby a strong magnetic field is set up in the iron core 22.
