Automotive parts common and resistance type spark plugs
Aug 24, 2018

As a spark discharge generator, the spark plug is a broadband continuous electromagnetic radiation interference source. In order to suppress the strong interference of electromagnetic radiation caused by flashover to the radio field, protect radio communication and prevent malfunction of in-vehicle electronic devices, countries around the world have accelerated the development of resistive spark plugs since the 1960s. China has also issued a series of national standards for mandatory electromagnetic compatibility, which imposes strict restrictions on the radio interference characteristics of spark-ignition engine-driven vehicle devices, so the demand for resistive spark plugs has also increased significantly. The resistance type spark plug is not significantly different in structure from the ordinary type, and only the conductor sealant in the insulator is changed to a resistor sealant.
