An engine includes a cylinder block having a bore, a piston fitted into the bore so as to form a combustion chamber and to be able to reciprocate, a cylinder head for closing the combustion chamber and having valve bores communicating with the combustion chamber, and valves for opening and closing the valve bores. A heat insulating coating is applied on a wall face of at least one of the piston, the cylinder head, and the valves and facing the combustion chamber. The heat insulating coating includes resin and a plurality of hollow nanoparticles embedded in the resin, smaller in diameter than a thickness of the heat insulating coating, and smaller than or equal to 500 nanometers in size.
