                                                   Purpose of Ignition System

n  The purpose of the ignition system is to ignite the compressed air-fuel mixture in the engine combustion chambers.

Ignition System

The ignition system is used to ignite the fuel-air mixture in the engine. The starter system is the ignition system, plus the battery, and starter switch, relay, solenoid & electric starter motor. The ignition switch usually requires a key be inserted that works a lock built into the switch mechanism. It is frequently combined with the starter switch which activates the starter motor. The ignition locking system may be bypassed by disconnecting the wiring to the switch and manipulating it directly; this is known as hotwiring
