Netizens ask: What are the advantages of using precious metals as electrode materials for spark plugs?

Kang Chun replied: The precious metal electrode spark plug has several outstanding advantages, which are manifested in the following aspects:

①The high corrosion resistance of the electrode makes the ignition gap remain unchanged for a long time, the ignition gap is stable, the engine runs smoothly, and there is no need to modify the engine ignition gap. Data shows that the ignition gap only increases by 0.05mm after an engine using platinum spark plugs has been running for 160,000 kilometers.

②Because the ultra-fine precious metal electrode has a sharp discharge effect, it is easier to ignite, and the engine can run smoothly at low speed.

③The ultra-fine electrode weakens the heat absorption and flame suppression effect of the electrode, and the flame core is easier to form to ignite the mixture, so that the combustion is more complete and the emission is lower.
