Abstract: Provided is a thermally insulated insert member and an engine having the thermally insulated insert member. Thermally insulated insert member is disposed in an intake port of a cylinder head of the engine. The thermally insulated insert member includes a guide member that guides a flow of intake air flowing in t he intake port; and a thermally insulative support member with a shape that can be fitted within the intake port. The guide member is formed of a metal and is supported in the intake port via the thermally insulative support member.

Abstract: An internal combustion engine includes an anisotropic thermal conductivity member (37, 51) provided on a wall surface defining a cylinder or a wall surface of a cooling water passage on a side of the cylinder, a thermal conductivity of the anisotropic thermal conductivity member in an axial direction of the cylinder being higher than a thermal conductivity of the anisotropic thermal conductivity member in a radial direction of the cylinder, and a thermally insulating member (38. 52) provided on an outer surface of the anisotropic thermal conductivity member with respect to the radial direction of the cylinder.
