摘要： An internal combustion engine piston includes a crown surface including a low thermal conductivity part lower in thermal conductivity than a base material. The low thermal conductivity part includes a porous member made of a glass material lower in thermal conductivity than the base material, and impregnated with the base material. A first material is interposed at least partly between the porous member and the base material in the low thermal conductivity part, wherein the first material is water-soluble, and has a higher melting point than the porous member.

摘要： 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.

摘要： A piston of an internal combustion engine includes a crown portion; a pair of thrust-side and counter-thrust-side skirt portions; and a pair of apron portions connecting the thrust-side skirt portion with the counter-thrust-side skirt portion. Each of the pair of apron portions includes an upper end wall connected with the crown portion, and a pin boss portion supporting a piston pin. A reverse-surface-side portion of the crown portion is formed with a hollow portion extending along an outer surface of the upper end wall of the apron portion. The upper end wall of the apron portion includes a bending portion between an outside surface of the pin boss portion and a circumferential end of the skirt portion. The bending portion bends in a step-like manner from the outside surface of the pin boss portion toward the circumferential end of the skirt portion.
