  • Charge density control for an internal combustion engine
    Patent number: 7277788
    Abstract: Apparatuses and methods for determining a desired charge density for an engine. A first characteristic indicative of an engine speed of the engine is determined. A second characteristic indicative of a load on the engine is determined. A value indicative of a desired charge density of a combustion mixture for the engine is determined as a function of the first and second characteristics.
    Type: Grant

  • 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.
