Platinum iridium alloy
The resistance type spark plug is equipped with a 5-10kΩ resistor in the spark plug. The resistance type spark plug can suppress the radio interference of the automobile ignition system. The side electrode of the resistance type spark plug is two or more spark plugs.
1.Terminal nut: Using industry standards screw cap, high marginal adaptation andincrease tightness with ignition system.
2.Insulator: Used by high aluminum alloy ceramics, alumina content 90%, have reliable leakproofness, durableness and heat resistance.
3.Bolt: Mi10 riveting screw steel, pass tensile test.
4.Underglaze color smooth surface durable printing fluently front.
5.Housing: Using by new manufacturing techinique, high precision, highantioxidation and pass endurance test to ensure durability.
6.Housing carving: Rolling carving, clear and balance carving with delicate font.
7.Electrode: Nickel alloy/Iridium/Platinum, long service life: Pass the ignitability and durability test, is high performance cost ratio spark plug.
The resistance type spark plug has the advantages of large heat absorption, good anti-fouling ability, etc., and can be directly cooled by the intake air to reduce the temperature, so it is not easy to cause hot ignition, so the thermal adaptation range is wide.
As a spark discharge generator, a 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 communications and prevent malfunction of on-board electronic devices, since the 1960s, the development of resistance type spark plugs has been accelerated, and the demand for resistance type spark plugs is also large. For increase. The resistance type spark plug is not much different from the ordinary type in structure, except that the conductor sealant in the insulator is changed to a resistance sealant.
