Sealing improvement

In the past, when spark plug sealing technology was lacking, product performance was often degraded due to dew condensation, cable damage, and penetration of other foreign substances due to leakage of hot gas inside the combustion chamber. Our company has improved the performance of the product by improving its own sealing to perfectly seal even the pressure of 20kg/cm2 in the case of a product that has been used for a long time.

Voltage induction with low resistance conductor (semiconductor) coating

In the case of existing air gap type products, there was a problem that sparks were generated at the part where the insulation was destroyed while the output voltage of the igniter exciter was delivered to the spark plug. To solve the problem, a low-resistance conductor coating was applied to the end of the spark plug to induce voltage even in case of insulation breakdown.

Application of various connection methods

Koryo Engineering can directly check the site and refer to the actual product to manufacture a customized spark plug.

Use of heat-resistant alloy steel

The main cause of spark plug failure is reduced life due to prolonged direct exposure to high temperature flames. To compensate for this, we were able to extend the life of the spark plug by using Inconel, which has good corrosion resistance at high temperatures.
