摘要： A piston ring for sealing a cylinder wall to a piston body is provided. The piston ring includes a ring body of an elastically deformable material which extends substantially circumferentially around an axis and has an inner face that faces the axis. The inner face includes a plurality of axially spaced and radially inwardly extending contact features. The ring body configured to bias the contact features into engagement with the piston body to establish a seal therebetween. At least one of the contact features extends substantially continuously around a circumference for establishing a substantially continuous seal around the piston body, and at least one of the contact features is non-continuous and has at least one recessed area for allowing the passage of oil and gas therethrough.

摘要： A low friction coating for an internal combustion engine and a method of forming a low friction surface on at least one of the engine's friction-sensitive components. In one form, a solid lubricant precursor additive is combined with motor oil such that upon work being performed on the combination by adjacently-interacting engine components, the solid lubricant tribochemically reacts to form a friction-reducing coating or film. In one preferred form, the coating or film is triboformed on a cylinder bore or a liner configured to fit within the bore. The reciprocating movement between the cylinder or liner and a piston and/or piston rings promotes in-situ formation of the layer after the engine has already been manufactured rather than during engine fabrication or assembly.

摘要： A cylinder liner for an internal combustion engine includes a liner body defining a longitudinal axis coated with a coating on the interior surface of the liner body that varies in thickness along the longitudinal axis. The coating on the interior surface is thicker in a region of the interior surface corresponding to a top dead center or a bottom dead center of a piston.

摘要： An engine assembly including a piston for rectilinear reciprocation within a cylinder. Rectilinear reciprocation of the piston allows for a sealing off of a fuel chamber such that fuel may be maintained and delivered to a combustion chamber independent of any lubrication oil to be employed at the interface of the piston and an inner wall of the cylinder. Additionally, the piston may be considered self-lubricating or monolithic in nature due to the presence of passageways for transferring engine fluids therethrough.

摘要： A diesel engine is fitted with a thin-walled wet liner fabricated of steel. The liner has a hardness that is within 10-20 Rc of the hardness of the piston rings carried on a piston within the liner. The inner surface of the liner is manufactured with a TRD=5Rvk (100−Mr2) of between 30 and 400 μm, and a compound liner thickness to bore diameter in the range of 1.5 to 4 percent.

摘要： An internal combustion engine 10 is provided with cylinders 19 having a predetermined surface finish thereon comprising of at least two differing patterns. The first pattern is designed to provide a predetermined storage volume for oil used to lubricate a piston 22 which is slidingly engaged in the cylinder 19. The second pattern is different to the first pattern in that it provides little or no storage capacity for the oil. The second pattern is applied to the wall 28 of each cylinder 19 at one or more positions where impingement of unburned fuel against the cylinder wall 28 is to be expected. The reduced storage volume of the second pattern reduces the volume of unburned fuel that can be transferred from the cylinder 19 to the oil supply of the engine 10.

摘要： A cylinder block for an automotive internal combustion engine. The cylinder block comprises a cylinder block side wall which includes a boss section located corresponding to a position between adjacent cylinders and is formed with an oil dropping passage through which lubricating oil to be returned to a crank case is introduced. In this cylinder block, the oil dropping passage is located adjacent the boss section and includes an upper passage portion, a lower passage portion, and an intermediate passage portion connecting the upper and lower passage portions. The cylinder block side wall includes an outer wall surrounding the intermediate passage portion of the oil dropping passage. The outer wall has an axially extending side section located at one side in an engine cylinder row direction. The axially extending side section linearly integrally connects the lower end of the boss section and the lower deck.

摘要： A restoration sleeve for the remanufacture of cast iron engine blocks or aluminum blocks with cast iron liners includes a sleeve formed of cast iron and having a relatively thin wall, a selected length, an outer diameter to achieve a non-interference fit within an overbored cylinder, an inner diameter equal to the original specifications of the original manufacturer of the engine block, and a helical cross hatched inner surface finish. The sleeves are manufactured by placing an unfinished sleeve in a boring fixture, boring the inner surface to a selected diameter, transferring the bored sleeve to a honing fixture, and honing the inner surface to the required diameter and surface finish. An adhesive is applied to the restoration sleeve and the overbored block cylinders, and the sleeves are inserted into the overbored cylinders wherein the adhesive is allowed to cure to thereby adhesively retain the sleeves within the block. A fluorescent dye is used in the adhesive for inspection by ultraviolet light to insure continuous and complete application of the adhesive to the restoration sleeve and the bored cylinder surface.
