Description:

For motorcycles with gasoline engines, the radio donors are vital. Therefore it can not hurt to know some basic things about the structure and function of the small but important parts.


Spark plug design in detail

• connection nut (nut cable connector) for the spark plug. Forwards the ignition of the firing pin to the electrode.

• firing pin in conductive molten glass enclosed gas-tight steel pin as an electrical conductor and connection to the center electrode.
• insulator consists of an aluminum oxide ceramic and isolates the center electrode to 40,000 volts to ground.
• candles body (nickel). If in the heat shrinking process gas tight connected to the insulator, with thread to secure the candle in the engine block.
• outer sealing ring The captive ring is designed for sealing and heat dissipation.
• glass melt, the electrical connection between the firing pin and the center electrode can be blended with a defined resistance are provided by corresponding to Entstöreigenschaften to influence erosion and.
  

• He inner sealing ring forms a gas-tight connection between the insulator and the metal body and is used for heat dissipation.
• center electrode with nickel clad copper core (some with platinum or iridium tip), the insulator is embedded in the.
• He insulator extends into the combustion chamber and heat, significantly affects the value of the spark plug.
• Introduction approach facilitates the screwing of the candle.
• breathing space influenced the self-cleaning properties.
• for ground electrode is made ​​of erosion-resistant alloys and, together with the center electrode, the Funkenstrrecke.
