Glow Plugs Work Principle.

- Feb 01, 2018-

The spark plug's electric plate ignites the mixture in the cylinder through repeated on-power ignition. At this time, other parts of the ignition system generate high-voltage electric pulses at the right moment to form a spark and generate energy for explosion to provide engine power output.

The spark plug structure is based on a slender metal plate through a ceramic material with insulation function made of the lower insulator around a metal shell, screwed to the way in the cylinder head, in the The bottom of this metal shell in the welding of a welding electrode and the car body to form a grounding effect. In addition, the end of the center of the electrode must be separated by a small discharge gap.

Then, the high-voltage current from the distributor will be conducted through the central electrode and then discharged at the discharge gap at the bottom. At this time, the spark plug functions to generate a spark-burning mixture, and the engine will generate energy and output power.

It can be seen that the spark plug is a device that ignites the mixed gas of gasoline and air that enters the engine to burn. Under the harsh conditions of high temperature and high pressure, the spark plug is one of the wearing parts of the gasoline engine and plays a role in the operation of the engine Important role, and the car fuel-efficient or not, smooth operation, have a lot to do.
