Capacitor discharge ignition system

摘要

Breakerless capacitor discharge ignition system for internal combustion engines in which a charge coil and ignition coil are disposed on ferromagnetic core. A changing flux is established by rotation of permanent magnets past the core. The charge coil is connected to charge a capacitor in circuit with a silicon controlled rectifier (SCR) for discharging the capacitor through the primary winding of an ignition transformer. The charge coil and transformer are wound on the core such that voltages of opposite polarity are simultaneously induced therein by the changing magnetic flux. A half way voltage of one polarity charges the capacitor and a voltage of opposite polarity induced in the secondary winding by the changing magnetic flux triggers the SCR to its conductive state discharging voltage stored on said capacitor through the primary winding of the ignition coil.
