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.
Claims5
An internal combustion engine, comprising:
- a cylinder block defining a cylinder receiving a piston and a cooling water passage provided radially outwardly of the cylinder;
- an anisotropic thermal conductivity member bonded to a wall surface of the 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 provided on an outer surface of the anisotropic thermal conductivity member with respect to the radial direction of the cylinder.
