Solid State Ignition 670527

The author presents a brief description of a present day automotive ignition system with an explanation of its various components. The moving parts of the ignition system such as the distributor shaft which is driven from the cam shaft, centrifugal weights which move the cam, vacuum advance mechanism, and rubbing block with breaker points and rotor can and will be eliminated with the aid of solid state electronics.
An analysis of the ignition coil and factors influencing its design as well as its vital part in the present-day system is reviewed. Also mentioned briefly are the transistor system and capacitor discharge ignition system and their current state of application. It is believed that solid state devices and integrated circuits will develop greater reliability and greater cost advantages for the consumer.
