    摘要： A capacitor discharge ignition (CDI) system for a light-duty spark ignition combustion engine includes an analog control circuit having a charging circuit, a trigger circuit and a shutdown circuit. In response to activation of a kill-switch, the shutdown circuit causes a switching device to discharge an ignition capacitor. Through the use of an RC circuit, the switching device continues to be biased such that it prolongs the discharge of the ignition capacitor, thereby preventing it from storing charge for the upcoming ignition pulse. This generally continues until the engine has come to a stop, at which time the engine can be immediately restarted without having to reset anything. The control circuit may also include engine speed limiting and ignition timing features.

    摘要： A method and system for operating an engine wherein ignition of the engine is activated according to a predetermined timing schedule that references engine speed, and the ignition is suppressed above a predetermined engine speed threshold to allow engine speed to fall below the predetermined engine speed threshold. Thereafter, ignition is reactivated according to timing that is retarded relative to the predetermined timing schedule for a predetermined number of engine revolutions substantially when the engine speed has fallen below the predetermined engine speed threshold, thereby mitigating undesirable spikes in combustion chamber maximum pressure.

    摘要： The ignition system for internal combustion engines comprises a rotor (10) and an armature (15) provided with an ignition coil (16,17) in which voltage signals, each having pulses (a,b,c,d) of opposite polarities are cyclically induced during each revolution of the rotor (10); a control unit for the ignition current comprises a current-control switch (Q1) which can be triggered during a positive pulse of the voltage signals, to cut off the current in the primary winding (16) and generate a high voltage on the secondary winding (17) of the ignition coil. A second control switch (Q3) has the control electrode connected both to a current-control resistor (R11) in series with the current-control switch (Q1), and to the outlet of a voltage comparator (U1) connected to a timing circuit (C2,Q2,C3) enabling the sparking within a pre-established time interval, during a positive pulse of each voltage signal, preventing the sparking when the engine is running below a minimum rotational speed, during the forward rotation and at the reverse rotation of the same engine.

    摘要： In an engine ignition system utilizing an AC generator (1) for supplying an electric power to an ignition coil (13), a phase relationship between the generator voltage and an ignition timing (T1) is determined so that an electric current flowing through a primary winding (L1) of the ignition coil (13) due to the voltage generation by the AC generator (1) at the ignition timing (T1) is greater than a predetermined current (Ad) required to produce a sufficient spark from a spark plug (14). Such an ignition system can advantageously ensure achieving ignition even when the battery is disconnected or totally discharged. Preferably, a capacitor (C1) is connected in parallel with the primary winding (L1) of the ignition coil (13). A stator core (6) for supporting a stator coil (5) in the AC generator (1) may be circumferentially displaceable to adjust the phase relationship between the ignition timing and the generator voltage.
