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. The piston further includes an airfoil surface formed in the flat crown surface. The airfoil surface has a convex shape and extends annularly around the rim of the bowl.

Abstract: A steel piston with an oil gallery, and process for forming a steel piston oil gallery channel, which corresponds to the complex shape of the combustion bowl in the piston crown. The oil gallery channel is first forged to the basic shape that corresponds to the shape of the walls of the combustion bowl. Machine-turning surfaces in the oil gallery channel can be machine-finished as desired. Surfaces in the oil gallery which cannot be machined with conventional turning operations, such as recesses and protrusions into the channel, are left in the original forged condition.

Abstract: A tool and a method of using the tool are provided for forming an engine component. The engine has a block defining a first cylinder and a second cylinder spaced apart by a bore bridge. The bore bridge defines a first cooling passage spaced apart from a deck face and extending transversely, and a second cooling passage positioned between the first passage and the deck face and extending transversely. The first and second passages are formed by a casting skin. In forming the engine component, a die is provided that defines a locator recess and at least one core. An insert is positioned into the recess on the die. The insert has a cast shell surrounding a lost core. The component is die cast with the die and the insert to form a cooling jacket. The insert is adapted to form the cooling passages for the bore bridge.

Abstract: A steel piston for an internal combustion including a cooling gallery containing a solid coolant, such as an aluminum-based material, is provided. The solid coolant has a thermal conductivity which is greater than the thermal conductivity of the steel material and fills at least 15 volume percent (vol. %) of the cooling gallery. The solid coolant provides for exceptional cooling along a crown of the piston, reduces corrosion and erosion along the crown, and avoids the problem of oil coking.

Abstract: A piston for use in 4 Cycle reciprocating Internal Combustion Engines. The one embodiment includes a multifunctional Engraving or Imprint that is machined into the crown of the piston. This “Imprint” consists of concentric circles of metal removed in a machining process resulting in the compartments of the functional areas within the crown of the piston connected by either the height and or cross drillings within the Imprint. The functional result is to create low and high pressure zones within the crown of the piston as it proceeds upward on the compression stroke facilitating the creation of an active moving rotational swirl in the outer 25% on the top surface area of the piston circumference. The active swirl pattern results in ultimate homogenization of the air fuel mixture leaving no area of the combustion chamber with weak or separated air and fuel molecules resulting in enhanced power and complete combustion.
