COMBUSTION CHAMBER STRUCTURE FOR ENGINE, CYLINDER HEAD, AND ENGINE

A combustion chamber is defined by a cylinder block, a cylinder head, and a piston. The cylinder head includes: a head body that has a lower surface opposing the combustion chamber; and a coat layer that covers the lower surface. The coat layer includes: a heat-insulating layer that is arranged in t...

Beschreibung
Zusammenfassung:	A combustion chamber is defined by a cylinder block, a cylinder head, and a piston. The cylinder head includes: a head body that has a lower surface opposing the combustion chamber; and a coat layer that covers the lower surface. The coat layer includes: a heat-insulating layer that is arranged in the lower surface and has lower thermal conductivity than the head body; a heat-shielding layer that is arranged to cover the lower surface and has the lower thermal conductivity than the head body and the heat-insulating layer; and a heat diffusion layer that is arranged between the heat-insulating layer and the heat-shielding layer and has the higher thermal conductivity than the heat-insulating layer and the heat-shielding layer. The heat diffusion layer abuts the head body.
