Spark plugs
Is the heat value of spark plugs important for a perticular engine?
The spark plug heat value (almost always expressed by a number in the centre of the spark plug type marking) is a very important spark plug parameter. If a plug is chosen that is too hot for the engine, serious damage to the sparkplug and engine may occur, if too cold spark plug is chosen, the electric insulation resistance of spark plug will be reduced due to conductive deposit build up on the spark plug insulator surface and the plug will fail to properly ignite the air/fuel mixture inside the ignition chamber.
Are there any manufacturing standards for spark plug production?
Brisk spark plugs are manufactured in the production process of a certified quality system as required by car manufacturers in Europe and America – ISO 9001, VDA 6.1, QS 9000. Among other things these systems guarantee global purchase of material, supplier assessment, cooperation in engine development, production process management and so on.
