Ignition Coil


Ignition coils are the ignition-system component that acts as a transformer to step up (increase) the battery voltage to many thousands of volts. The high voltage surge from the coil is transmitted to the spark plug to ignite the compressed air-fuel mixture It converts a battery's voltage into thousands of volts required to ignite fuel by creating an electric spark in the spark plugs. In some electronic ignition systems, the voltage may go up to  47,0000 volts or higher. The voltage causes sparks to jump the gap at spark plugs.

Ignition Distributor

  • The ignition distributor has a set of contact or breaker points that functions as a fast-acting switch, When the points close, current flows through the coil When the points open, current flow stops and the coil produces a high voltage surge, A condenser connects across the points. It aids in the collapse of the magnetic field and helps reduce arcing that burns away the points

Ignition Switch

  • The ignition switch connects the ignition coil to the battery when the ignition key is ON. When the key is turned to START, the starting motor cranks the engine for starting

Ignition System

The purpose of the ignition system is to ignite the compressed air-fuel mixture in the engine combustion chambers. This should occur at the proper time for combustion to begin. To start combustion, the ignition system delivers an electric spark that jumps a gap at the combustion chambers ends of the spark plug.
