Silicon nitride ceramic glow plugs are used for diesel engine start-up preheating and ignition of various high-temperature gases. This product uses silicon nitride ceramics as the base material of the heating part, which overcomes the problems of metal sleeve-type glow plugs, such as not resistant to high temperatures, short service life, and long pre-heating time .
The following is the detailed information of our products:
