It is a question concerning the IRIDIUM TOUGH that is often.
|
||
|---|---|---|
| Yes. The reason is that the 0.4mm center electrode of IRIDIUM TOUGH lowers the required voltage compared to 2, 3 and 4 electrode plugs and provides superior ignitability. |
| <Required voltage> Required voltage decreases as the electrode gets thinner because the electric field strength affecting required voltage becomes stronger. As shown in the following diagram modeling each electrode shape, IRIDIUM TOUGH requires less voltage than the 2 electrode plug. |
||
 |
||
 |
||
|
||
| <Ignitability> Cooling effect from the electrode decreases and ignitability increases to the extent that the contact area between the flame kernel and electrodes is smaller. Due to its 0.4mm center electrode, IRIDIUM TOUGH has less contact area between the flame kernel and electrodes and better ignitability than 2 electrode plugs. |
