Ignition System

Auto Systems and Repair

The ignition system supplies the "spark" to each cylinder, which is necessary to begin the combustion process. 

Ignition systems have evolved from using a mechanical distributor and special wires to transmit the spark from the ignition coil to each spark plug, to a fully electronic system which has an ignition coil mounted directly on top of each spark plug. Routine maintenance has been reduced from a "tune-up" every 12,000 miles to simply replacing the spark plugs every 100,000 miles.


Spark Plug
The spark plug uses the energy produced by the ignition coil to generate the spark necessary to ignite the air/fuel mixture in the combustion chamber. More >>


Crankshaft Position Sensor
The crankshaft position sensor measures the rotational speed and the positional location of the crankshaft and transmits the data to the engine control computer. More >>


Key Component — Ignition Coil

The ignition coil converts low battery voltage into the higher voltage needed to produce the spark that ignites the fuel in each cylinder. More >>
