摘要： A spark plug for igniting fuel/air mixtures in internal combustion engines, in particular in internal combustion engines of motor vehicles. On its insulating-body foot, the spark plug has a coating which is intended to protect against misfirings and cold-starting difficulties as a consequence of electrically conductive deposits, in particular in the case of installation of spark plugs in new motor vehicles. The coating includes solvent-free silicone rubber or silicone resin. The silicone rubber may contain filler and is provided with silicone oil for the purpose of good processability. Expediently, the inner side of the metal housing which is exposed to the combustion chamber is also covered with the coating. The coating is physiologically safe, environmentally acceptable and resistant to handling, and does not require expensive extraction systems if it is sprayed onto the appropriate region of the spark plug by means of nozzles.

摘要： A spark plug having a tube-shaped, metal housing, an insulator which is retained by the housing, and an inner conductor arrangement embedded in the insulator, the inner conductor arrangement comprising one connection bolt, one burn-off resistor, one contact pin, and one platinum central electrode, and four ground electrodes, which are bent towards the central electrode and protrude beyond the insulator by the width of their thickness, being secured to the housing, the contact pin being coated and being shortened in its length such that the burn-off resistor is forward-positioned as far as possible towards the spark gap, and the platinum central electrode having a nail shape, whose rear part has a smaller diameter than its front part, which extends out of the insulator.
