Document Type and Number:
WIPO Patent Application WO/2013/161528
Kind Code:
A1
Abstract:
In the present invention, when forming a heat shield film by means of applying a heat insulating coating material or a heat shielding coating material to the wall surface of a combustion chamber, the heat insulating coating material or heat shielding coating material (heat shield film) is strongly bonded to the wall surface of the combustion chamber. This engine (10) combustion chamber structure is provided with a combustion chamber (16) demarcated by a cylinder bore (12), a cylinder head (15) bottom surface, and a piston (13) apex, and at least a portion of the wall surface of the combustion chamber (16) is configured from aluminum or an aluminum alloy. The engine (10) combustion chamber structure is provided with: a boehmite coating film (24) formed at the wall surface of the combustion chamber (16) configured from aluminum or an aluminum alloy; and a heat shield film (23) that is provided to the surface of the boehmite coating film (24) and is formed by means of applying a heat insulating coating material or a heat shielding coating material to the surface of the boehmite coating film (24).
