The other parts of the ignition system generate positive high voltage electrical pulses, which generate sparks and generate an explosion to provide the energy required for the engine power output.
   And the structure of the spark plug is made of an elongated metal plate through a ceramic material with an insulating function. The lower part of the insulator has a metal shell around it and is screwed to the cylinder head The bottom of the metal shell in the welding electrode and the car body to form a grounding effect. In addition, at the end of the center of the electrode, it must be separated by a slight discharge gap.
   Then, the high-voltage current from the distributor will conduct through the central electrode and then discharge at the discharge gap at the bottom, and the spark plug will function to produce a spark-burning mixture. The engine will generate energy and output power.
   It can be seen, the spark plug is to enter the engine combustion of gasoline and air mixed gas to ignite the device, working in high temperature, high pressure conditions, is one of the petrol engine consumables, it plays in the engine running quite Important role, and the fuel economy or not, the operation is smooth, have a great relationship.
