The difference between single platinum and double platinum spark plugs

1. The materials welded by the two electrodes are different. For single platinum spark plugs, only the electrodes are welded with flake platinum, and the side electrodes are thickened wedge-shaped. The center electrode and side electrode of the double platinum spark plug are both welded with platinum alloy spark plugs.
2. Double platinum has better performance than single platinum: it improves ignition and flashover performance, easily stabilizes in the optimal temperature range between self-purifying combustion and incandescent combustion, expands the thermal range, and has excellent durability.
