Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP3541665
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of avoiding the generation of deposit on the inner surface of a combustion chamber by attaining decomposition action to an organic material such as a lubricant or an unburned fuel causing the deposit.
SOLUTION: The organic material such as soot, the unburned fuel and the lubricant is decomposed and the deposit stuck on the inner surface of the combustion chamber is avoided by applying a silica sol incorporating the fine particle of a titanium oxide on the surface of parts constituting the inner surface of the combustion chamber such as the crown surface of a piston 2, the inner surface of a cylinder head and firing to form a titanium oxide layer 20 so that photocatalytic reaction of titanium oxide 21 is derived by the combustion light generated in the combustion chamber.
