How CDI Ignition Works: A Simple Breakthrough in Engine Performance
Published Time:
2026-03-09
The working principle of CDI is efficient and reliable. During engine operation, the charging circuit stores high‑voltage electricity in the capacitor. When the ignition timing is reached, the control circuit triggers a rapid discharge. The energy is sent to the ignition coil, which boosts the voltage to thousands of volts, creating a strong spark at the spark plug. CDI systems respond extremely quickly at high RPM, ensuring reliable ignition even under heavy load and high‑speed conditions.
