This product uses silicon nitride ceramic as the base body and tungsten wire as the heating source, with the tungsten wire embedded within the silicon nitride matrix. The assembly is formed into a solid unit through hot pressing and sintering, then precision ground and welded to create a durable ignition element. Suitable for use in parking heaters, this heating element is designed for cold climates where rapid fuel vaporization, ignition, and combustion are required in vehicle auxiliary heating systems. It enables quick cabin heating upon engine start-up and maintains performance during idle stop conditions.
