Why can industrial spark plugs still work stably in harsh environments?

Update:08 Nov, 2024

Industrial spark plugs are made of high-strength and high-corrosion-resistant materials, such as platinum, iridium alloy and other precious metals, which can resist the erosion of high temperature, high pressure and corrosive substances. Through precise manufacturing processes, each component of the spark plug (such as electrodes, insulators, etc.) can achieve extremely high precision and fit, thereby ensuring stability and reliability in harsh environments.

The electrode gap of the spark plug is a key factor affecting the breakdown voltage. By accurately designing the electrode gap, it can be ensured that under the action of high voltage electricity, electric sparks can be quickly generated between the electrodes to ignite the mixed gas. The insulator not only serves to isolate the electrode and the metal shell, but also can withstand the test of high voltage electricity and high temperature environment. By optimizing the structure and material of the insulator, the insulation strength and high temperature resistance of the spark plug can be further improved.

The spark plug is designed with efficient heat dissipation structures, such as copper cores, which can quickly dissipate the heat generated by the spark plug during operation, thereby keeping the operating temperature of the spark plug within a reasonable range.

Industrial spark plugs can withstand extremely high temperatures and corrosive substances. When the mixed gas burns, the lower part of the spark plug will be subjected to the impact of high-pressure gas and the test of high temperature; at the same time, the active substances in the combustion products (such as ozone, carbon monoxide and sulfur oxides, etc.) may also cause corrosion to the spark plug. However, due to the use of special materials and manufacturing processes, the spark plug can maintain stable operation in these harsh environments.

Spark plugs need to withstand alternating high voltages and mechanical shocks during operation. By using high-strength materials and optimizing the design structure, spark plugs can ensure stable insulation performance and mechanical strength under these extreme conditions.

After a long period of operation, some dirt or carbon deposits may adhere to the electrodes of the spark plug. However, due to the spark plug's self-cleaning ability (i.e. burning off the dirt attached to the electrode at high temperature), it can maintain long-term stability and reliability.
