Document Type and Number:
WIPO Patent Application WO/2012/114676
Kind Code:
A1
Abstract:
An engine is provided with a cylinder block comprising a bore, a piston that fits into the bore enabling free reciprocal motion so as to form a combustion chamber, a cylinder head with a valve hole that closes the combustion chamber and communicates with the combustion chamber, and a valve that opens and closes the valve hole. For at least one of the piston, the cylinder head, and the valve a wall surface that faces the combustion chamber is coated by a thermally insulating coating film. The thermally insulating coating film is constituted by a resin and a plurality of nanoscale hollow particles that are embedded in the resin and have diameters less than the thickness of the thermally insulating film and are 500 nanometers or less in size.
