▼The following is an introduction to the ignition electrode

1. Structure: The ignition electrode usually consists of two metal electrodes, called the center electrode and the ground electrode. The center electrode is located in the center of the electrode tip, while the ground electrode is fixed on an insulating support. There is a certain distance between the two electrodes to form a discharge gap.

2. Principle: The working principle of the ignition electrode is to use high voltage to generate arc or spark. When a high voltage is applied between the electrodes, the electric field strength increases, eventually causing the gas in the discharge gap to be ionized, forming a plasma. The arc, or spark, created by this plasma can ignite the fuel mixture.

3. Application: Sparking electrodes are widely used in combustion equipment such as internal combustion engines, flame spray guns, gas furnaces and gas water heaters. In internal combustion engines, the ignition electrode is usually used to ignite the gas mixture and start the combustion process in the engine.

4. Material selection: The material selection of the ignition electrode is critical to its performance and life. Common materials include copper alloys, nickel alloys, and platinum alloys. These materials have good electrical conductivity and high temperature resistance, and can withstand high-energy discharges.

5. Maintenance and replacement: The ignition electrode will be worn and corroded during use, so it needs regular inspection and maintenance. If the electrode is severely worn or fails, it may be necessary to replace the electrode to ensure proper ignition performance.
