Sparkplug controls the ignition system,as the name indicates it sparks the petrol air mixture.There's an electrode placed in it,the electrode is used as the conducter.When high current passed through it from a battery  current will jump from the electrode to the conducter which shaped like hook.This current jump is known as the spark.The spark can combust the compressed air fuel mixture.The spark system is also well timed as the valve mechanism(sparks in the power stroke).The spark plug has a great part in the engine efficiency,if the plug can combust the fuel completely then the spark plug is ideal.So the duel sparking is placed in the newer engines.Spark plug have to be well maintained(clean alternately).The figure shows simplest working of a spark plug.
