Glow plugs


Glow plugs have the function to heat the combustion chamber, thus facilitating the starting of the Diesel cycle engines in colder days. After starting the engine, these spark plugs should be maintained connected to avoid malfunctions, while the engine does not reach the ideal operating temperature. This process reduces the level of emissions of pollutants and smoke in the cold phase of the engine.

Glow plugs are specifically developed for each type of engine and heating system. The temperature and the heating time can vary according to the heating system.

NGK has two types of glow plugs:
– Metallic resistance glow plug (Y Type)
– Ceramic resistance glow plug (C Type)
