Heat resistance: Adapted to extreme heat? Extremely cold conditions

The internal temperature of the spark plug reached 2000℃ when the mixed gas was burned, and the low temperature gas was cooled in the suction stroke, so that the hot and cold phenomenon of the 4-punch engine turned the 2 turn in the engine operation into a turn.

As with this heat resistance, exothermic properties that do not reach the starting point of surface fire are also required.

Mechanical strength: can adapt to drastic pressure changes

In the suction stroke to reach 1 gas pressure below, detonation half stroke can reach more than 45 air pressure. The only mechanical strength that can adapt to this drastic change in pressure.

Insulation: Maintains high voltage insulation

High voltages of about 10 to 30kV are required to maintain adequate insulation in the case of rapid temperature changes and repeated pressure changes.

Air tightness: Maintain air tightness in a hostile environment

It is required to maintain air tightness between the mechanical housing and the insulator under drastic temperature changes and pressure changes.

Attrition resistance: Minimize electrode consumption

This resistance is required to minimize electrode consumption in harsh environments.

Stain resistance: Reduces burning dirt to a minimum

Under bad environment, restrain the dirt of electrode caused by the combustion of mixed gas. The attached activated carbon will also be heated and burned to achieve the self-cleaning requirements. Thus, even at low speeds, the spark plug temperature can be rapidly increased up to (about 500℃).
