This vehicle mechanical component includes a mechanical component body, a heat insulating layer formed on the mechanical component body, and a protective layer formed on the heat insulating layer and including an inorganic compound that includes an alkoxide and scale-like inorganic solid particles dispersed in the inorganic compound.

Vehicle mechanical component and piston

This piston includes a piston main body made of aluminum or an aluminum alloy, used in an internal combustion and a modified layer formed on a surface of a strength reinforced portion of the piston main body, having a surface made of aluminum oxide by plasma oxidation, to which compressive residual stress is applied.

Piston and method for manufacturing piston

A mechanical component for an internal combustion engine includes a mechanical component body made of one of aluminum and aluminum alloy and used for the internal combustion engine, a nickel plating layer formed to cover a surface of a predetermined portion of the mechanical component body, and a reforming layer formed between the surface of the predetermined portion of the mechanical component body and the nickel plating layer.

Mechanical component for internal combustion engine, manufacturing method of mechanical component for internal combustion engine, and mechanical component

Any one or more members of an engine, that is, a piston, a cylinder head and a valve, has a wall face disposed face-to-face to a combustion chamber, and the wall face is coated by a heat-insulation coating film. The heat-insulation coating film includes a heat-insulative layer formed on a surface of the wall face, and an inorganic-system coated-film layer formed on a surface of the heat-insulative layer. The heat-insulative layer includes a resin, and first hollow particles buried inside the resin and exhibiting an average particle diameter being smaller than a thickness of the heat-insulative layer. The inorganic-system coated-film layer includes an inorganic compound.

Engine and piston

A sliding component for an internal combustion engine includes: a sliding component main body that includes a plurality of concave portions formed in a predetermined portion thereof; and a coating layer that covers a portion of the sliding component main body, in which the plurality of concave portions are not formed.

Sliding component for internal combustion engine and method of manufacturing sliding component for internal combustion engine

A piston for an internal combustion engine includes a piston main body for the internal combustion engine, and a crosshatched groove being formed on a surface of the piston main body. The crosshatched groove includes a crosshatch angle that corresponds to a crossing angle of lines that configure a crosshatch, the crosshatch angle that is set at a range from equal to or greater than 15 degrees to equal to or less than 35 degrees.

Piston for internal combustion engine and manufacturing method thereof

A valve timing control device comprising, a cam shaft assembled within an engine, a rotational transmitting member having a concave portion, which is mounted around the cam shaft to rotate relative thereto within a predetermined range for transmitting a rotational power from a crank pulley, vanes provided on the cam shaft, fluid chambers formed between the cam shaft and the concave portion, which are separated into advancing and delaying chambers by the vanes, a fluid supplying means for supplying fluid under pressure to a selected one of the advancing and delaying chambers, and a stopper located between a radially inner portion of a side wall of the concave portion and the vane to restrict rotate relative between the rotational transmitting member and the cam shaft.
