The purpose of the ignition system is to generate Very high voltage from the car’s 12-volt battery, And to send this to each spark plug in turn, Igniting the fuel-air mixture in the engine ‘s combustion chambers. The coil is the component that produces this high voltage. It is an electromagnetic device that converts the low-tension (LT) Current from the battery to high-tension (HT) Current each time the distributor contact-breaker points open. The distributor unit consists of a metal bowl containing a central shaft, Which is usually driven directly by the camshaft or, Sometimes, by the crankshaft. The bowl houses the contact-breaker points, rotor arm, And a device for altering the ignition timing. It also carries the distributor cap. Distributing … Continue reading How the ignition system works
