Spark Plug – SB008I

The spark plug is an important component of the ignition system of fuel vehicles. It can introduce high-voltage electricity into the combustion chamber and make it jump across the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. The spark plug is mainly composed of the connection nut, insulator, connection screw, center electrode, side electrode and housing. The side electrode is welded to the housing.
When working, the spark plug not only has to constantly withstand the sudden changes in temperature, pressure and chemical corrosion in the combustion chamber, but also has to withstand at least 30,000 volts of ignition high-voltage pulses. Therefore, the spark plug must have perfect mechanical, electrical and chemical properties throughout its service life.
Performance requirements of the spark plug:
Mechanical performance:
The ceramic and electrode materials of the spark plug should have sufficient mechanical strength to withstand the impact
