関用ピストンの構造。 In an internal combustion engine piston in which the piston pin axis is offset toward the thrust side with respect to the longitudinal axis of the piston, the shape of the oil hole at the bottom of the oil ring groove of the piston is such that the thermal conductivity on the thrust side with respect to the piston skirt is equal to the heat on the anti-thrust side. A structure of a piston for an internal combustion engine, characterized in that the conductivity is greater than that of the piston.
