Abstract: A heavy duty piston for an internal combustion engine comprises a thermally conductive composition filling 10 to 90 vol. % of a sealed cooling gallery. The thermally conductive composition includes bismuth and/or tin. For example, the thermally conductive composition can be a single-phase binary mixture of bismuth and tin. The thermally conductive composition has improved thermal properties, for example a melting point around 139° C., a thermal conductivity around 22 W/m·K, and a thermal diffusivity around 1.43E-5 m2/s. The thermally conductive composition is not reactive and does not include toxic or cost-prohibitive metals. During high temperature operation, as the piston reciprocates in the cylinder bore, the thermally conductive composition flows throughout the cooling gallery to dissipate heat away from the upper crown and thus improve efficiency of the engine.

Abstract: A robust engine assembly having reduced weight and efficient cooling, without an increase in fuel consumption or carbon dioxide emissions, is provided. The engine assembly includes a double-wall cylinder liner clamped between a cylinder head and a crankcase. A manifold is disposed along a portion of the cylinder liner and includes fluid ports aligned with fluid ports of the cylinder liner to convey cooling fluid to a cooling chamber located between the walls of the cylinder liner. For example, the manifold can be a low-loss hydraulic manifold cast integral with the crankcase. Tie rods connect the cylinder head to the crankcase to clamp the cylinder liner in position. Alternatively, the tie rods can be connected to a main bearing cradle located beneath the crankcase. No attachment features extend into the walls of the cylinder liner, which is especially advantageous when the cylinder liner is formed of aluminum.

Abstract: A power cylinder assembly for an internal combustion engine includes a cylinder wall that surrounds a cylinder bore that extends along an axis. A piston assembly is positioned in the cylinder bore, and the piston assembly has a combustion surface that divides the cylinder bore into a combustion chamber on one axial side of the combustion surface and a crank case on an opposite axial side of the combustion surface. The combustion surface is partially defined by a first upper surface of a first piece and partially defined by a second upper surface of a second piece. The second piece is moveable relative to the piston body during operation of the power cylinder assembly to change a compression ratio of the power cylinder assembly.

Abstract: A piston for an internal combustion engine comprises a sealed cooling gallery extending circumferentially around a center axis beneath a bowl rim of an upper crown. A metal-containing composition having a high thermal conductivity fills a portion of the sealed cooling gallery to dissipate heat. The metal-containing composition includes a base material having a melting temperature less than 181° C. and a plurality of metal particles having a thermal conductivity greater than the thermal conductivity of the base material. For example, the metal-containing composition can comprise copper particles dispersed in silicone oil, or copper particles dispersed in a mixture of alkali metals. During high temperature operation, as the piston reciprocates in the cylinder bore, the base material is liquid and flows throughout the cooling gallery to dissipate heat away from the upper and lower crowns.

Abstract: A piston for an internal combustion engine including a piston body (20). The piston body (20) defines a first cooling chamber (46) that is sealed closed and contains a first cooling medium (48) other than air. During operation of the piston, the first cooling medium (48) extracts heat from the surrounding regions of the piston body (20) to cool the piston body (20). The piston body (20) also defines a second cooling chamber (50) adjacent to the first cooling chamber (46). A cooling oil (51) is projected into the second cooling chamber (50) and against the portion of the piston body (20) separating the first and second cooling chambers (46, 50) to extract heat from the first cooling medium (48). The cooling oil (51) is redirected within the second cooling chamber (50) to extract additional heat from the first cooling medium (48) or directly from the piston body (20).
