摘要： A process for coating a cylinder or a liner of an internal combustion engine may involve a plasma assisted chemical vapour deposition (PACVD) technique. The process may include placing a component to be coated in a PACVD system; forming a negative pressure within the system in an inert atmosphere including argon, hydrogen, or a mixture thereof; activating a surface of the component at a bias voltage of 300 to 550 Vbias; performing an ionization of the component at a bias voltage of 800 to 1200 Vbias; depositing an adhesive layer having a precursor element on the surface of the component; depositing a transition layer having a gradient content of increasing amorphous carbon and decreasing precursor element; and depositing an upper layer composed of an amorphous carbon with the precursor element.

摘要： The invention proposes a liquid-cooled assembled piston (1) having an upper part (2) and a lower part (3), wherein the upper part (2) and the lower part (3) are connected to one another by means of a radially outer annular support (12) and by means of a radially inner annular support (11). An outer cooling duct (13) is arranged between the outer support (12) and the inner support (11), and an inner cooling duct (18) is arranged radially within the inner support (11). Here, the outer cooling duct (13) is connected to the inner cooling duct (18) by means of at least one overflow duct (22, 22′). According to the invention, in order to reduce the compression height and therefore the axial dimensions of the piston, and in order to ensure an unimpeded discharge of cooling oil situated in the inner cooling duct (18) with little design expenditure, a bolt (20) with an outer thread (23) is arranged coaxially with respect to the piston axis (17) on the underside, which faces away from the piston head, of the piston head (4); the upper part (2) and the lower part (3) of the piston (1) are screwed to one another by means of a hexagonal nut (19) which can be screwed onto the outer thread (23) of the bolt (20); and the hexagonal nut (19) has, at the piston head side, a collar (25) with at least one radially arranged bore or milled portion (26, 27) which connects the inner cooling duct (18) to the piston interior space (28).

摘要： An internal combustion engine includes: a cylinder block having one or more cylinders, a cylinder liner in a tubular shape disposed inside the cylinder; a piston reciprocating inside the cylinder liner and having a top land portion formed of an outer periphery of the piston sandwiched between a piston head and an uppermost ring groove; and a liner installation ring forming, inside the cylinder, a circular step portion protruding toward the inner periphery of the cylinder liner. The liner installation ring is disposed in the cylinder block or the cylinder liner in such a manner that the bottom face of the liner installation ring face to the uppermost portion of the cylinder liner. The liner installation ring is disposed at a position in accordance with the upper end position of the top land portion when the piston reaches a top dead center. The liner installation ring is set to protrude from the inner periphery of the cylinder liner in an inward direction at a length of 0.05 mm or more to 0.5 mm less.

摘要： A lubricating system for an outboard motor equipped with a vertical type engine. In one embodiment, the lubricating system has an oil pump positioned near the bottom of the engine, the oil pump driven by an oil pump rotor that is positioned at a connection between the crankshaft and an engine drive-shaft, the oil pump rotor being linked to the crankshaft. The system further includes a camshaft-driving mechanism for transmitting the rotation of the crankshaft to a propulsion device. The camshaft-driving mechanism is also positioned at the connection between the crankshaft and the drive-shaft and is also linked to the crankshaft. The lubrication system also has a main oil tank for storing lubricating oil circulated by the oil pump, and an engine-cooling water passageway positioned next to the main oil tank. Another element of this embodiment of the lubricating system is a filter-mounting base positioned on an outer wall of the cylinder blocks. The system also has oil passageways positioned at the bottom of the cylinder blocks for distributing the oil.
