Description

Double-layer insulating ceramic ignition electrode structure Technical Field The utility model relates to the technical field of ceramic igniters, in particular to a double-layer insulating ceramic ignition electrode structure. Background Ceramic ignition needle ignition electrodes are an important component commonly used in ignition systems for internal combustion engines. The main function of the engine is to generate sparks in the combustion chamber of the engine to ignite the mixed gas, thereby realizing the normal operation of the engine. In this text, I will describe in detail the structure, working principle and application area of the ceramic ignition needle ignition electrode The ceramic ignition needle ignition electrode is typically composed of two parts, one being a needle-like electrode and the other being a ceramic insulator. Needle electrodes are typically made of platinum alloys because of their high resistance and corrosion resistance. The ceramic insulator is made of ceramic materials, and the ceramic has good insulating property and heat resistance. The structural design can ensure that the ignition electrode can work normally under high-temperature and high-pressure environments. The principle of operation of the ceramic ignition needle ignition electrode is to ignite the fuel in the combustion chamber by arc discharge. When the ignition system is powered on, high voltage current is transmitted to the ignition electrode through the electric wire. At this time, under the action of the high-voltage current, air near the ignition electrode is ionized to form an arc. The high temperature and energy generated by the arc ignites the fuel in the combustion chamber, causing deflagration, thereby allowing the engine to operate normally. Ceramic ignition needle ignition electrodes play a vital role in internal combustion engines. It not only can ignite fuel quickly and stably, but also can provide reliable ignition capability under different working conditions. Because of the special materials and structures of the ignition electrode of the ceramic ignition needle, the ceramic ignition needle can bear high-temperature and high-pressure environments, and has longer service life and better wear resistance. Therefore, it is widely used in internal combustion engine equipment such as automobiles, motorcycles, and generators. The existing ceramic ignition needle is inconvenient to install in use, so that the ceramic ignition needle cannot be detached and installed effectively and rapidly in use, and the ceramic ignition needle is inconvenient to use.
