Title:
INTERNAL COMBUSTION ENGINE AND METHOD OF PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/025812
Kind Code:
A3
Abstract:
An internal combustion engine (10) in which an anodic oxidation coating film (61, 62, 63, 64) is formed on all or a portion of a wall that faces a combustion chamber (NS), wherein the anodic oxidation coating film (61, 62, 63, 64) has a structure that is provided with a bonding region in which each of hollow cells (C) forming the coating film is bonded to the adjacent hollow cells (C), and a nonbonding region in which three or more adjacent hollow cells (C) are not bonded to each other, and wherein a porosity of the anodic oxidation coating film (61, 62, 63, 64) is determined by a first void (Kl) present in the hollow cell (C) and a second void (K2) that forms the nonbonding region.
