Ceramic Spark Plug

Ceramic spark plug, part or all of the spark plug parts made of ceramic materials. It is mainly composed of ceramic heating element and insulating shell. Spark plugs work under high temperature, high pressure and high voltage, and require electrical insulation, mechanical strength, heat resistance, corrosion resistance and good sealing. Traditional metal spark plugs such as nickel-manganese alloy have a short service life, while platinum and iridium are expensive. Spark plugs made of high-performance ceramic materials have obvious advantages.
