An ignition system serves to create spark and deliver it to each cylinder for the continuous running of the combustion process. From the first mechanical distributors that required a tune-up every 12000 miles to modern distributor-less computer-controlled ignition systems with an ignition coil mounted on the top of each spark plug, it has been an integral part of any gasoline vehicle.
A modern ignition system consists of many parts and components, each of which is crucial for its smooth and efficient operation. Let’s check a couple of them:
A spark plug is where high voltage generated by the ignition coil is turned into sparks. It is used to ignite the air/fuel mixture inside a cylinder.
Crankshaft position sensor
The job of the crankshaft position sensor is to measure the rotational speed of the crankshaft as well as to determine its position, so the engine control unit can provide correct ignition timing.
An ignition coil is a low-to-high voltage converter, generating high voltage needed for igniting fuel in the combustion chamber.
