The capacitive-discharge ignition uses capacitor to discharge current to the ignition coil to fire the spark plugs. The history of the capacitor discharge ignition system can be traced back to the 1890s when it is believed that Nikola Tesla was the first to propose such an ignition system.

2024年5月19日 · The basic CDI system is a trigger mechanism, coils, and a box, often black, with capacitors and other circuitry inside. The trigger tells the box to fire, the box determines when to fire which coil with the capacitors, and zap goes the spark plug, ad infinitum.

A Capacitor Discharge Ignition or CDI is an electronic ignition device that stores an electrical charge and then discharges it through an ignition coil in order to produce a powerful spark from the spark plugs in a petrol engine. Here the ignition is provided by the capacitor charge.

2025年2月12日 · In this post I have explained the circuit for a simple, universal capacitive discharge ignition circuit or a CDI circuit using a standard ignition coil and a solid state SCR based circuit. The ignition process in any vehicle becomes the heart of the entire system as without this stage the vehicle just won’t start.

2025年1月31日 · The term CDI stands for Capacitor Discharge Ignition, a system that has revolutionized motorcycle ignition technology. We’ll explore the different types of CDI boxes, how to identify them, their functionalities, and why understanding them is …

Capacitor discharge ignition (CDI) systems operate on the principle of efficiently charging and discharging a capacitor. This system is designed to provide a rapid burst of energy to the ignition coil, causing the spark plug to spark and start the engine. Let's dive into each step to better understand how this happens in real-time.

The charging coil is responsible for generating electrical energy from the engine’s rotational motion, which is then used to charge the capacitor. The trigger coil plays a crucial role in the CDI system, as it provides the timing signal to determine when to release the stored energy in …

CDI: Capacitive Discharge Ignition. The spark necessary to ignite the air/petrol mixture in the combustion chamber is produced by the CDI module. This system consists of 7 stages. The HV supply differs from small motors to automobiles. The small one or two cylinder motors one or two stroke have a fly-wheel which includes a supply winding.
