Abstract (en)

[origin: EP3263876A1] An object of the present teaching is to provide an engine that is able to suppress generation of scuffs more effectively. The present teaching provides an 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 is made of an Al alloy with an Si content of 16% by mass or more. The sliding surface has Si primary crystal grains and an Al alloy base material exposed thereon so as to be contactable with the piston part, the Si primary crystal grains having an average crystal grain diameter of 8 µm or more and 50 µm or less, the sliding surface having a plurality of substantially parallel linear grooves formed therein at such a pitch that a plurality of linear grooves exist between the Si primary crystal grains.
