Sparking Plugs TRIZ Cases
- Spark Plug Noble Metal Tip Joining via Laser Welding
Laser welding creates a molten boundary between the noble metal tip and ground electrode, preventing oxidized scale progression that causes joint separation.
- Dilute Nickel Alloy Spark Plug Electrode Oxidation Resistance
Zirconium and boron additions in a dilute nickel alloy spark plug electrode resist oxidation and sulfidation at elevated temperatures.
- Spark Plug Center Electrode Thermal Expansion Management
Segmented center electrode enhances thermal radiation while preventing insulator breakage through controlled thermal expansion clearance.
