Spark Plug

タイトルまたは説明

The spark plug plate by repeated continuous power ignition, ignites the mixture in the cylinder, at this time, the other part of the ignition system is a high voltage pulse is generated when the formation of spark and explosion engine power output required energy.
The structure of spark plug is a thin metal plate with a through with insulation function made of ceramic material, a metal shell around the lower part of the insulator, screwed on the cylinder cover with screw tooth in this way, the metal shell at the bottom of the welding electrode and a car body to form a connection the role of. In addition, the end of the center of the electrode must be separated by a small discharge gap.
Then, from the high voltage current distributor to the central electrode, and then discharge at the bottom of the discharge gap, then the spark plug function spark combustion gas mixture, the engine will get energy and output power.
Thus, the spark plug gasoline will enter the engine combustion and air mixed gas to ignite the device, bad working conditions in high temperature and high pressure, is one of the parts of the gasoline engine, it plays a very important role in the operation of the engine, and the car fuel economy or not, whether smooth operation, have great relationship.
