An object of the present invention is to provide an ignition device for an internal combustion engine, especially an automatic engine in a motor vehicle, in which the spark duration can be set sufficiently long in a particularly low 1797 rpm range.

ρによって短絡もしくは開放されることができる。FIG. 1 shows the basic principle of a control device according to the invention for igniting a spark plug 2 of, for example, a four-cylinder internal combustion engine. Each of the spark plugs 2 is equipped with a transformer having a primary winding ap and a secondary winding 6t which are supplied with power from a control circuit VC (not shown), and the secondary winding S is connected to the t pole of the spark plug 2. 7vc coupled and bridged by a mechanical, electromechanical or electronic switch or ρ. Weird 8
Above the winding S on the secondary side of the E-equipment is an additional winding S', the current circuit of which can be short-circuited or opened by the switch or ρ.

IPの影響なしに行なわれるというところにちる。A short circuit in the additional winding, lJS', by the switch or ρ will either extinguish or reduce the secondary 1st pressure in the winding fils, or lower the F until there is no spark at the spark plug. On the other hand, when the switch or .rho. is opened, the necessary voltage reaches the electrodes of the spark plug and ignition occurs in an orderly manner. The key point of the principle of the generation and extinction of the secondary voltage high voltage according to the present invention is that this is the primary
The reason is that it is done without any influence from IP.

Therefore, the impedance returned to the plug terminal is lower than the apparent impedance of the spark plug 2, and the spark disappears or is not generated.

? This is less than in the case of a J-style ignition system. In addition to this, the duration of the spark can be made arbitrarily long and precisely determined compared to known systems, and the primary winding is controlled by a interrupter and therefore by an alternating voltage. Ru. This step 1 is performed regardless of the engine speed. The magnetic flux is the same in all transformers and has no influence on the primary windings or glands due to the ignition process. Furthermore, a certain amount of spark is shared. The energy of the spark can be varied arbitrarily as adjusted by the electronic control unit. This ultimately results in improved combustion of the air/fuel mixture, especially at low engine speeds.

Since switch 1c or ρ is closed, no voltage is generated in the secondary winding S as already mentioned. First, @EC+ is now closed, and then the necessary electrons are generated by opening switch I or ρ, so that the ignition of spark plug Z1 takes place. spark plug zl

It is not necessary to fully use mechanical or electronic circuit breakers, which are subject to high requirements, because they are always interrupted before or after. The cost of the ignition device according to the invention according to FIG. 4 is therefore significantly reduced. This is because, apart from the convenience of only one high voltage coil, a breaker is used which does not have any high voltage requirements. For example, breaker C

ことが可能である。A'ri is a symbol for a sensor or a transmitter, and by means of this word E, the switch block in FIG. 6 receives an opening/closing command. The start and end of the ignition time at B, where the action of the switch is shown, is indicated at 1a and 70. Is there a secondary volume when the switch is opened? The high voltage required for tss is generated, resulting in spark plug Zl -z4
A spark is generated. In the ignition diagram according to FIG. 7, the time during which the sector of the distributor rotor is in the range 1 to 4 at the point of contact at Zl -Z4 is indicated by a dashed line. As can be seen from FIG. 7, the ignition time is shorter than this time. It is therefore possible to increase the ignition duration as desired by enlarging the sectors of the distribution quadrotor.
