  • Spark plug configurations with electrode to direct charge flow for a combustion pre-chamber of an internal combustion engine
    Patent number: 11799271
    Abstract: Spark plugs are disclosed that include electrode arrangements to improve the charge flow into and out of the annular volume around the insulator nose and a pre-chamber volume of a pre-chamber device, thus directing a purge of exhaust gases trapped in the annular volume to a space formed by the exterior of the spark plug body and the interior of the pre-chamber device.
    Type: Grant

  • Combustion pre-chamber assemblies for an internal combustion engine
    Patent number: 11614027
    Abstract: A combustion pre-chamber assembly includes pre-chamber device body defining an annular plenum that is in fluid communication with the at least one bore that extends through the spark plug shell. The annular plenum is also in communication with at least one purging passage that extends from the annular plenum to an end surface of the pre-chamber device body. Residual exhaust gases in the annular volume of the spark plug are purged by fresh charge flow from the main combustion chamber as the piston approaches top dead center. The fresh charge flow that is provided to the annular plenum through the at least one purging passage and into the annular volume of the spark plug through the at least one bore through the spark plug shell.

  • Compressor bypass flow arrangement
    Patent number: 10961900
    Abstract: Methods and devices are disclosed for introducing a compressor bypass flow that is returned from location that is downstream of a pressure source of an internal combustion engine to an air filter housing that is located upstream of the pressure source.
