Preheating Plug is an important parts of automobile ignition system, the preheating Plug (Glow plug-in), commonly known as electric Plug, English for: Glow plug-in. Is a subsidy heater, accessorial equipment used on the diesel engine start process.
role
When the diesel engine is started, because the outside of the low temperature, makes rely on air intake, compression, explosion, exhaust cycle process, difficult to start the engine cycle, subsidies for heating is required at this time. This device installed in the upper part of the engine cylinder preheating chamber and nozzle below. When the diesel is jet atomization, through preheating plug by heating. When the gas is compressed, the explosive, start the engine cycle, achieve normal engine cycle work.
classification
According to the electric plug, heating time, can be divided into slow and fast electro-thermal plug type.
According to the material, can be divided into metal electric heating and the ceramic electro-thermal plug.
