摘要： An object of the present teaching is to provide an air-cooled engine that is able to improve cooling efficiency, and particularly cooling efficiency at a time of initial sliding of a piston part. The present teaching provides an air-cooled engine including a piston part and a cylinder body part with a sliding surface on which the piston part is slidable. The cylinder body part includes a heat dissipation portion provided on an outer surface of the cylinder body part, and is made of an Al-containing metal. At least an inner peripheral portion of the cylinder body part, which includes the sliding surface, is made of an Al alloy with an Si content of 16% by mass or more. The sliding surface is configured such that a plurality of substantially parallel linear grooves are formed therein and Si primary crystal grains having an average crystal grain diameter of 8 µm or more and 50 pm or less are exposed thereon so as to be contactable with the piston part. An Al contact portion where an Al alloy base material has contact with the piston part, which is formed between the plurality of linear grooves, is exposed on the sliding surface at a location between two adjacent Si primary crystal grains. Al contained in the cylinder body part is physically continuous from the Al contact portion to the heat dissipation portion.

摘要： An obj ect is to suppress a problem caused to an internal combustion engine, including a diamond-like carbon layer provided on an outer circumference of a piston ring, due to a gap between a piston skirt and a cylinder wall not having an appropriate size. A piston included in an internal combustion engine in an embodiment according to the present invention includes a piston head; a piston ring attached to an outer circumference of the piston head; and a piston skirt extending along the cylinder wall from the outer circumference of the piston head. The piston ring includes a diamond-like carbon layer on an outer circumference thereof. The piston skirt includes a slidable portion slidable against the cylinder wall. The slidable portion includes a resin layer in at least a part thereof, the resin layer preventing heat of the piston from being transmitted from the piston skirt to the cylinder wall.
