IPC: F02P3/08
Filed: 1984-08-27
Abstract: PURPOSE:To enable to perform automatic lead angle during high speed rotation, by a method wherein, in case a negative exciter voltage is higher than a capacitor voltage for signal, a capacitor for a signal is charged, and in case it is lower than the capacitor voltage for signal, the gate signal of thyristor is provided. CONSTITUTION:A capacitor C0 is charged by means of a positive exciter voltage between (a) and (b) of an exciter coil L1, and is discharged by turning ON a thyristor SCR, and a high voltage is induced to the secondary circuit of an ignition coil L2 for ignition. Meanwhile, a capacitor C1 is charged by a negative exciter voltage between (b) and (c) of the coil L1, and is discharged through a resistor R1. When a voltage between (b) and (c) is higher than a voltage of the C1, a transistor Tr1 is turned ON, and a Tr2 is turned OFF. When lower, reversely, the Tr2 is turned ON, a gate voltage is fed to an SCR, and when higher than a trigger level, the SCR is turned ON. Thus, an exciter voltage period is low during high speed rotation, and since the C1 is not completely discharged at a generating time of a negative exciter voltage, ignition is effected in a further lead angle position compared with that during low speed rotation.
