    Abstract: A piston for an internal combustion engine includes a piston body forming a crown portion and a skirt portion. The skirt portion includes a bore that is arranged to receive a pin for connecting the piston to a connecting rod. The crown portion forms a bowl surrounded by a flat crown surface having an annular shape. The bowl and the flat crown surface meet along a circular edge surrounding a rim of the bowl. The piston further includes an annular protrusion disposed within the bowl adjacent the rim. The annular protrusion has a generally convex shape in cross section created by an upper, inwardly extending surface and a lower, inwardly extending surface that meet along a convex apex. The piston further includes a recirculation surface formed within the bowl adjacent the annular protrusion. The recirculation surface meets the lower, inwardly extending surface along an inflection edge.

    Abstract: A nozzle for a member of a fuel combustion system of an engine includes a hollow nozzle body. The nozzle body includes an outer surface, an inner surface, and an orifice surface. The outer surface defines an outer opening. The inner surface defines an interior chamber and an inner opening. The orifice surface defines an orifice passage extending between, and in communication with, the outer opening and the inner opening. The orifice passage is in communication with the interior chamber via the inner opening. The orifice surface includes a boundary surface and a protrusion. The protrusion projects from the boundary surface radially inwardly into the orifice passage.

    Abstract: A component of a fuel combustion system of an engine includes a body and a thermal conductor member. The body includes a fuel surface configured to be in heat-transferring relationship with a fuel source within the fuel combustion system. The body is made from a first material having a first thermal conductivity value. The thermal conductor member is disposed within the body and is made from a second material, which is different from the first material and has a second thermal conductivity value that is higher than the first thermal conductivity value. The thermal conductor member includes a first end disposed adjacent the fuel surface and a second end in distal relationship thereto. The thermal conductor member extends between the first and second ends along a thermal conduction path defined within the body and extending away from the fuel surface.

    Abstract: A piston for an internal combustion engine includes a piston body forming a crown portion and a skirt portion. The skirt portion includes a bore that receives a pin for connecting the piston to a connecting rod, and the crown portion forms a bowl surrounded by a flat crown surface having an annular shape and disposed along a plane. The bowl and the flat crown surface meet along a circular edge surrounding a rim of the bowl. The piston further includes an annular protrusion disposed within the bowl adjacent the rim. The annular protrusion has a generally convex shape in cross section created by an upper, inwardly extending surface and a lower, inwardly extending surface that meet along a convex apex.
