Ignition system

Patent ·
OSTI ID:5536219

An ignition system is described for an internal combustion engine which consists of: CDI magnet means comprising a generating coil for generating electricity, an ignition capacitor charged by the generating coil for storing the electricity generated by the latter, and an ignition coil including a primary winding which receives a supply of the electric charge of the ignition capacitor as the latter discharges when a signal is supplied to a gate of a thyristor; and signal generating means comprising a signal coil, a first capacitor and a second capacitor and constituting a gating circuit of the thyristor, the signal coil supplying a signal to the first capacitor to charge same, the electric charge stored in the first capacitor being passed through a constant current circuit to the second capacitor to charge same, the second capacitor discharging through leak resistors, whereby a signal is supplied through transistors to the gate of the thyristor when the voltage of the second capacitor reaches a predetermined level.
