What controls the diesel glow plug of vehicle?

When the diesel engine starts, because of the low temperature outside, it is difficult to start the engine cycle depending on the process of intake, compression, explosion and exhaust cycle, so it is necessary to supplement heating. This device is installed in the preheating chamber of the upper part of the engine cylinder and under the fuel injection nozzle. When the diesel oil is atomized, it will be heated through the preheating plug. When the oil and gas is compressed, it is easy to explode and start the engine cycle to achieve normal engine cycle. According to the heating time of the glow plug, it can be divided into slow type and fast type. According to the material, it can be divided into metal glow plug and ceramic glow plug.
