Ignition system

Purpose ?

An ignition system generates a spark or heats an electrode to a high temperature to ignite a fuel-air mixture in spark ignition internal combustion engines, oil-fired and gas-fired boilers, rocket engines, etc. The widest application for spark ignition internal combustion engines is in petrol (gasoline) road vehicles such as cars and motorcycles.

Compression ignition Diesel engines ignite the fuel-air mixture by the heat of compression and do not need a spark. They usually have glowplugs that preheat the combustion chamber to allow starting in cold weather. Other engines may use a flame, or a heated tube, for ignition. While this was common for very early engines it is now rare.

Main classification falls into two category (These are old systems)

     Magneto  systems 

    Battery and coil-operated ignition

   

some other terms related  (relatively modern ) are 

          Switchable systems

Mechanically timed ignition

Electronic ignition

        capacitor discharge ignition

Digital electronic ignitions
