    Abstract: A multi-cylinder engine including a donor cylinder, a non-donor cylinder, at least one intake manifold, and at least one camshaft is provided. An intake valve of the donor cylinder controls a flow of air into the donor cylinder. The donor cylinder fluidly communicates exhaust gases to an exhaust gas recirculation (EGR) system. An intake valve of the non-donor cylinder controls a flow of air into the non-donor cylinder. The at least one camshaft controls an opening and closing of the intake valve of the non-donor cylinder such that the intake valve of the non-donor cylinder is maintained open for a first intake duration. The at least one camshaft controls an opening and closing of the intake valve of the donor cylinder such that the at least one intake valve of the donor cylinder is maintained open for a second intake duration which is greater than the first intake duration.

    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.

    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.
