Ignition System: Description and Operation

PURPOSE / OPERATION
The ignition system uses Electronic Control Unit activated electronic ignition to generate high voltage and direct it to spark plugs at each cylinder. Voltage must be high enough to jump the spark plug gap under compression and it must be supplied at the correct time under a wide range of operating conditions.

COMPONENTS
^ Ignition coil.
^ Camshaft driven distributor with integral crank angle and camshaft sensor.
^ Ignitor.
^ Distributor cap and high tension wiring for distributing high voltage to the spark plugs.
