Definitions

  • the invention is based on an ignition system according to the preamble of claim 1.
  • Such an ignition system is already known from FR-A-2 241 991.
  • an induction coil is inserted into the circuit of the primary winding, which has an iron core. This measure is intended to give the ignition voltage pulse a steep rising edge there, in order to ensure a safe ignition of a fuel-air mixture even with sooty spark plugs with a low shunt resistance.
  • FIG. 1 shows an ignition system with the measure according to the invention
  • FIG. 2 shows an ignition system that has been slightly modified compared to FIG. 1
  • FIG. 3 shows a core for the induction coil preloaded in 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 powered from a current source 1, which can be the battery of the motor vehicle.
  • a negative line 2 leads from the negative pole and from the positive pole a supply line 4 containing an operating switch 3.
  • the supply line 4 initially runs via an induction coil 5, then via the primary winding 6 of an ignition coil 74 and finally via an interrupter 8 to the ground line 2.
  • the secondary winding 9 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 an ignition system without an induction coil 5 - is halved.
  • each of the primary windings 6 must have such an induction coil 5 be upstream ( Figure 2).
  • the invention can also be used in transistorized coil ignition systems, i.e. in such an ignition system in which the interrupter 8 is a controlled transistor.
  • a laminated sink core is selected as the core 11, as shown in FIG. 3.
  • a material with a magnetization curve should be selected 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.
