Definitions

  • the invention relates to an ignition system according to the preamble of the main claim. It is already known (according to DE-PS 23 53 556) an ignition system lying in this direction, in which an induction coil is also provided in the circuit of the primary winding, but which gives the ignition pulse voltage there a steep rising edge and thus a safe one Inflammation of the fuel-air mixture wants to reach even with sooty spark plugs. In such and in general with all ignition systems in which the ignition energy is stored in an ignition coil, there is a risk that when the circuit of the primary winding is switched on, the secondary voltage of the ignition coil rises so high that a so-called "switch-on spark” and thus a preliminary flame of the Air-fuel mixture occurs, which is undesirable. Advantages of the invention
  • FIG. 1 shows an ignition system with the measure according to the invention
  • FIG. 2 shows a somewhat modified ignition system
  • FIG. 3 shows a core for the induction coil upstream of the primary winding
  • FIG. 4 shows an induction (B) field strength (H) diagram with the course of the magnetization curve , for example for the core in FIG. 3.
  • the ignition system shown in Figure 1 is intended for the internal combustion engine, not shown, of a motor vehicle, also not shown.
  • the ignition system is fed from a power source 1, which can be the battery of the motor vehicle.
  • a power source 1 can be the battery of the motor vehicle.
  • a line 2 connected to ground and from the positive pole an operating switch 3 containing supply line 4.
  • the supply line 4 initially runs; via an induction coil 5, then via the primary winding 6 of an ignition coil 7 and finally via an interrupter 8 to the ground line 2.
  • the secondary winding 8 the ignition coil 7 also has a connection to the ground line 2 via at least one spark plug 10.
  • the induction coil 5 is provided with a core 11 made of magnetically conductive material, which according to the invention is an at least almost closed core. With such a core, it can be achieved that the secondary voltage generated when the circuit containing the primary winding 6 and the induction coil 5 is switched on - compared to such ignition systems without an induction coil 5 - is halved.
  • the invention can also be used in transistorized coil ignition systems, i.e. in ignition systems in which the interrupter 8 is a controlled transistor.
  • a laminated iron core is selected as the core 11, as shown in FIG. 3.
  • a material with a magnetization curve should be chosen for the core, which is at least approximately a steep straight line a at first and changes into an only moderately increasing saturation curve b, as is the case in the induction (B) field strength (H) - Diagram according to Figure 4 is shown. Further corrections of the magnetization curve are possible by giving the core 11 an uneven cross-sectional shape, for example by constrictions 12 (FIG. 3).

Abstract

Une installation d'allumage pour moteurs à combustion interne comprend un circuit qui part d'une source de courant (1) et qui contient l'enroulement primaire (6) d'une bobine d'allumage (7) et une bobine d'inductance (5) à noyau magnétiquement conducteur (11) connectée en série avec l'enroulement primaire (6). Ce noyau (11) est un noyau presque fermé, ce qui a l'avantage de réduire considérablement la tension transmise à l'enroulement secondaire (9) lors de la mise sous tension de l'enroulement primaire (6), en évitant l'apparition d'étincelles de fermeture et un allumage précoce du mélange d'air et de carburant.
