Semi-superficial
discharge type
|
|
The
semi-superficial discharge type spark plug is designed to
produce sparks along the isolator surface in the metal cover
direction. The sparks burn the adhered coal, providing this
way greater resistance against dirty.

Superficial
discharge type
|
|
This
spark plug has a smaller heat exposed isolator surface exposed
and is a super- old spark plug; therefore, it gets dirtyy easily.
To overcome dirty, a capacitor discharge system is used which
reaches rapidly the required voltage to produce the sparks.
It is used in engines of high performance like the engines of Formula 1. |
