Claim:
Electrical ignition method for combustion engines through the use of an arrangement of several coils (U 1 , LS; U 2 , TS; U 5 , Lp, Ls) and a magnet wheel or magnet generator (P, M, S, N) which rotates synchronously 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 (U 1 ; U 2 ; U 5 ), which are used: for charging an energy storage element (U 4 ), which is discharged by actuating an ignition switch (U 9 ) via a primary coil (Lp) of a pulse transformer (U 5 ) 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 (U 8 ), which is deployed for actuating an ignition switch (U 9 ) 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 prevents a discharge of the energy storage element (U 4 ) during a stopping and coast down procedure of the combustion engine or actuates its charging, so that a charged energy storage element is available for the next start of the 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 (U 1 ) and a subsequent second limb (Kb) surrounded by at least the primary coil (Lp) of a pulse transformer (U 5 ) or an auxiliary coil (U 2 ); (b) outputting signals (LSn, c, a) of both the charging coil (U 1 ) on the first limb (Ka) and the primary coil (Lp) or the auxiliary coil (U 2 ) on the second limb (Kb) each to the control unit (U 8 ); (c) for the purpose of inducing a continuous ignition advance (ZZP) as the rotational speed increases, detecting, using the control unit (U 8 ), the chronological occurrence in each case of the first ( 2 , 10 ) of the alternating voltage half-waves ( 2 , 4 , 6 , 8 ; 10 , 12 , 14 , 16 ) by monitoring the voltage levels of the alternating voltage half-waves ( 2 , 4 , 6 , 8 ; 10 , 12 , 14 , 16 ) and activating the ignition switch (U 9 ), as the first ( 2 , 10 ) of the alternating voltage half-waves occurs; and (d) building-up ( 40 ) the control unit's supply voltage through the charging coil (U 1 ) on the first limb (Ka) whereby the control unit (U 8 ) immediately scans and checks the levels (c,a) of the primary coil voltage (PS) or the trigger coil (U 2 ) 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 ).
