  • Spark plug having an encapsulated electrode gap
    Publication number: 20040100179
    Abstract: Spark plugs in an internal combustion engine may have an encapsulated spark gap allowing for improved emissions and efficiency. However, increased temperatures in an ignition chamber about the spark gap may cause pre-ignition of a air fuel mixture in a combustion chamber. A purge passage allows hot exhaust gas to be expelled from the ignition chamber and thus reduce likelihood of pre-ignition.
