Ignition system, easy to start for internal combustion engines

Electrical ignition method for combustion engines through the use of an arrangement of several coils (U1, LS;

• U2, TS;
• U5, Lp, Ls) and a magnet wheel or magnet generator (P, M, S, N) which synchronously rotates with the combustion engine, where the magnetic field of the magnet generator intermittently flows through the coils (LS, TS, Lp, Ls) and therein generates a sequence of magnetic flux changes (Ba, 1, 3, 5, 7;
• Bb, 9, 11, 13, 15), whereby a sequence of corresponding alternating voltage half-waves (2, 4, 6, 8;10, 12, 14,16) is induced in the coils (U1;
• U2;
• U5), which are used:
• for charging an energy storage element (U4), which is discharged by actuating an ignition switch (U9) via a primary coil winding (Lp) of a pulse transformer (U5) for initiating an ignition spark (FU),
• and for generating an operating voltage or voltage supply (VDD) for an electronic, analog or digital or programmable control unit (U8), which is deployed for actuating an ignition switch (U9) at an ignition point (ZZP) in dependence of the acquired alternating voltage half-waves (2, 4, 6, 8;
• 10, 12,14,16) or from the state of the combustion engine
• and through the use of a stop or switch-off system for the combustion engine, which is technically designed or arranged for programming or switching to prevent a discharge of the energy storage element (U4) during a stopping and coast down procedure of the internal combustion engine or to actuate its charging, so that a charged energy storage element is available for the next start of the internal combustion engine,
• characterized by,
• (a) detecting alternating voltage half waves from two different limbs of a magnet generator (P,M,S,N) having an iron, soft-magnetic yoke core in a U-shape with, in the sequence of the rotational direction (D), a first limb (Ka) surrounded by a charging coil (U1) and a subsequent second limb (Kb) surrounded by at least the primary coil (Lp) of a pulse transformer (U5) or an auxiliary coil (U2);
• (b) detecting the first (2, 10) of the alternating voltage half-waves (2, 4, 6, 8;10,12, 14, 16), outputting signals (LSn, c, a) of both the charging coil (U1) on the first limb (Ka) and the primary coil (Lp) or the auxiliary coil (U2) on the second limb (Kb) each to the control unit (U8);
• (c) for the purpose of inducing a continuous ignition advance (ZZP) as the rotational speed increases, the control unit (U8) monitoring the first exceedance within each respective magnet wheel or magnet generator rotation of a preset trigger voltage threshold (Ux), at least by monitoring one alternating voltage half-wave by means of the control unit (U8) and the control unit (U8) actuating the ignition switch (U9) when the preset trigger voltage threshold (Ux) is exceeded by said first exceedance;
• (d) building-up (40) the control unit's supply voltage through the charging coil (U1) on the first limb (Ka) whereby the control unit (U8) immediately scans and checks the levels (c,a) of the primary coil voltage (PS) or the trigger coil (U2) on the second limb (Kb) in order to determine whether there is the first (10) of the alternating voltage half-waves (10,12, 14, 16).
