  • Patent number: 9328693
    Abstract: A piston for reduced production of particulate matter during combustion of a fuel directly injected after a top dead center position includes a piston body defining a piston body diameter of about 263 mm, and a combustion face upon the first axial body end. The combustion face includes a combustion bowl, and an annular piston rim extending circumferentially around the combustion bowl. Inner and outer rim surfaces together comprise a horizontal width of the rim in a ratio of about 1:1 to about 2:1. The inner rim surface includes a chamfer sloping from about 9° to about 11°, such that a profile of the rim is relieved to limit deflection by the piston of the directly injected fuel toward a cylinder wall.

  • Patent number: 9238996
    Abstract: A piston for an internal combustion engine includes a piston body having an outer cylindrical surface defining a longitudinal piston axis, a combustion face defining a compound combustion bowl, and a compound rim extending radially outward from the compound combustion bowl to the outer cylindrical surface. The compound combustion bowl includes a convex inner bowl surface defining a conical projection and a concave outer bowl surface. The compound rim includes a flat outer rim surface adjoining the outer cylindrical surface, and a convex inner rim surface adjoining the compound combustion bowl. The convex inner bowl surface transitions smoothly to the concave outer bowl surface, and the convex inner rim surface transitions abruptly to the concave outer bowl surface at an edge of the compound combustion bowl.

  • Patent number: 8978621
    Abstract: A piston for a compression ignition internal combustion engine includes a piston body having a combustion face defining a combustion bowl, and the combustion face including a compound bowl surface and a compound rim surface. The combustion face is profiled to balance a combustion efficiency property of the piston with emissions properties of the piston, and includes a profile of rotation defining a convex curve segment bisected by the longitudinal axis, and a plurality of concave curve segments outboard of the convex curve segment. The profile of rotation further includes a compound rim profile defining a plurality of convex curve segments corresponding to an inner rim surface. The convex curve segment of the compound bowl profile defines a relatively small radius of curvature, and the plurality of convex curve segments corresponding to the inner rim surface define a relatively large radius of curvature.

  • Publication number: 20150020765
    Abstract: A piston for a compression ignition internal combustion engine includes a piston body having an outer cylindrical surface defined along a longitudinal piston axis. A piston includes a combustion face defining a combustion bowl including an inner bowl surface, an inner rim portion and an outer rim portion. The combustion face includes a cross-sectional profile of rotation about the longitudinal piston axis. A first profile of the profile of rotation includes a convex curve segment, a linear segment outboard the convex curve segments and a first set of concave curve segments outboard the linear segment. The first set of concave curve segments defines a first radius of curvature. A second profile is provided outboard the first profile and includes a second set of concave curve segments. The second set of concave curve segments defines a second radius of curvature greater than the first radius of curvature.
