    摘要： A piston for internal combustion engine has both fatigue strength and wear resistance without increased production cost. At least one of a combustion chamber surface, a skirt rib, a pin boss rib which connects a pin boss and a crown, a lower portion of the pin boss casting surface, and a surface layer including the casting surface is a first eutectic structure in which primary crystal Si does not crystallize. A top ring groove and a pin holing of a piston pin are finished surfaces obtained by eliminating the surface layer by means of machining. The layer including the finished surface is a second eutectic structure in which the primary crystal Si crystallizes.

    摘要： To provide a piston for an internal combustion engine including a skirt which causes a relatively small frictional resistance and can maintain a favorable frictional property over an extended period of time. In a piston for an internal combustion engine having a skirt 4 on whose sliding surface a resin coating layer is deposited, the skirt 4 comprises a thin walled portion 51 located in a circumferentially middle part thereof and a pair of thick walled portions 52 provided on either lateral side of the thin walled portion 51. The resin coating layer 44 at least in the part thereof deposited on the thick walled portions 52 is formed with a plurality of dimples 45. The skirt may comprise a skirt main body 41 extending axially at a fixed distance from the central axial line of the piston in an axially middle part thereof, and a first reduced diameter portion 42 depending from the lower end of the skirt main body and having a progressively smaller diameter toward a lower end thereof. The dimples 45 may be arranged along a first boundary 6 between the skirt main body and first reduced diameter portion.
