The glow plug is an important accessory in the automobile ignition system. The glow plug (Glow Plug), commonly known as the glow plug, is an auxiliary heater, which is used as an auxiliary device during the starting process of the diesel engine. Glow plug classification: According to the heating time of the glow plug, it can be divided into slow and fast type glow plugs. According to the material, it can be divided into metal glow plug and ceramic glow plug.
Glow plug function: When the diesel engine is started, due to the low temperature outside, it is difficult to start the cycle of the engine depending on the process of intake, compression, explosion, and exhaust cycle. At this time, subsidized heating is required. This device is installed in the preheating chamber on the upper part of the engine cylinder, below the fuel injector. When the diesel is sprayed and atomized, it will be heated by the glow plug. When the oil and gas are compressed, it is easy to explode, start the cycle of the engine, and achieve the normal cycle of the engine.
