  • Cylinder liner having intake ports for improved scavenging
    Patent number: 9074520
    Abstract: A cylinder liner for an engine is disclosed. The cylinder liner may have a hollow cylindrical sleeve extending from a first end to a second end along a longitudinal axis. The cylinder liner may also have a plurality of circumferentially spaced intake ports formed within the sleeve. The plurality of intake ports may have a first intake port positioned at a first axial distance from the first end. The plurality of intake ports may also have a second intake port positioned at a second axial distance from the first end.
    Type: Grant

  • Piston
    Patent number: 8683974
    Abstract: A piston for an engine may include a piston crown, and a piston bowl recessed within the piston crown. The piston bowl includes a center portion, a cone portion, and an annular toroidal portion. The geometry of the piston bowl is designed to correspond with a fuel injection nozzle having a specific spray angle. An exemplary piston bowl may include a toroidal major diameter between about 4.645 and 4.895 inches and a toroidal minor radius between about 1.165 and 1.235 inches. The cone portion includes an angle between about 26 to 34 degrees. The compression ratio of the piston is about 17.95 to 1.
