Definitions
- the present invention relates to a cylinder liner or cylinder for an internal combustion engine.
- the friction within the piston-piston ring-cylinder system can be divided into contact friction, mixed friction and hydrodynamic friction.
- the proportion of hydrodynamic friction takes up a large part of the total friction. This is one of the main reasons why ever lower viscosities are being sought for engine oils, because hydrodynamic friction is proportionally dependent on the oil viscosity.
- the oil viscosity in turn, depends on the temperature. Since the cylinder temperature along the stroke position is usually highest at top dead center and lowest towards the crankcase at bottom dead center, the oil viscosity at top dead center is low, with the oil viscosity increasing continuously towards bottom dead center.
- hydrodynamic friction is proportionally dependent on the piston speed. Because piston speed is highest in the middle of the piston stroke, you want low oil viscosity there to get low hydrodynamic friction.
- a cylinder liner of a reciprocating combustion engine known, which is used in a machine frame.
- the cylinder liner is in operative connection with a heat pipe which is essentially in the form of a jacket and which extends from a cooling water space to or into the collar, the heat pipe having means in its interior, e.g. a capillary structure, which transport the liquid heat transfer medium even against the force of gravity allow along the cylinder tube.
- DE 102 25 062 B4 already discloses a cylinder liner of a reciprocating internal combustion engine, which has at least a first coolant duct in the area of a top dead center of a piston movement of a piston of the reciprocating internal combustion engine and a group of second coolant ducts in the central liner area and in the area of a bottom dead center of a piston movement of a piston Reciprocating internal combustion engine are assigned.
- the technical task of the invention is to optimize the oil viscosity along the stroke position.
- the invention relates to a cylinder liner or a cylinder for an internal combustion engine, comprising an inner side which forms a running surface, the cylinder liner or the cylinder having at least one thermal insulation which extends in the circumferential direction around the cylinder liner or around the cylinder, wherein the insulation is spaced radially outward from the tread.
- the advantage of the cylinder liner according to the invention or the cylinder according to the invention is that heat dissipation via the cylinder liner is reduced by insulation in the cylinder liner, resulting in lower oil viscosity and thus lower hydrodynamic friction in this area.
- the insulation of the cylinder liner or the cylinder can be continuous or also extend only in sections around the cylinder liner or the cylinder. In an exemplary embodiment of the cylinder liner or cylinder, the insulation forms a closed ring that extends around the entire cylinder liner or cylinder.
- the insulation is honeycomb or mesh-shaped and runs around the entire cylinder liner or cylinder.
- honeycomb or mesh form compared to a closed ring form of insulation is that with such insulation, the webs carry loads caused by piston movement in the cylinder liner or cylinder. This reduces deformation and extends the life of the cylinder liner or cylinder.
- the cylinder liner or cylinder has an exterior with the insulation exposed on the exterior.
- An insulation that is exposed on the outside of a cylinder liner or cylinder is advantageous in terms of production and maintenance.
- the exposed insulation can also be created by painting or the like.
- the cylinder liner or the cylinder has an outer side, with the insulation being arranged between the running surface and the outer side.
- the insulation is designed as an evacuated or fluid-filled cavity.
- Vacuum thermal insulation insulates thermally by reducing the heat transport caused by the gas molecules in the air.
- the vacuum can prevent convection and, on the other hand, the thermal conduction of the gas molecules.
- An example for preventing the thermal conduction of the gas molecules is the design of a Dewar vessel.
- the cavity is filled with insulating material.
- the running surface has a length L in the axial direction, with the insulation starting at a distance of 5-30%, preferably 10-25%, particularly preferably 15-20%, and extending from there extends in the crankcase direction.
- the running surface having the maximum length L is measured from the upper or combustion chamber-side edge of the cylinder liner or the cylinder.
- the area of isolation is defined according to the previous feature because it does not make sense to start earlier due to the piston crown land heights since piston rings are not in the hydrodynamic area of engagement there.
- the temperature should be dissipated for cooling.
- the running surface has a piston stroke length K between a top dead center and a bottom dead center in the axial direction, with the insulation being spaced at a distance of 5 to 30%, preferably 10-25%, particularly preferably 15 20%, from top dead center spaced begins and extends from there towards the bottom dead center.
- the piston stroke length K relates to a piston movement of an engine for which the cylinder liner or the cylinder is intended.
- the area of isolation is defined according to the previous feature because it does not make sense to start earlier due to the piston crown land heights since piston rings are not in the hydrodynamic area of engagement there.
- the temperature should be dissipated for cooling. The insulation can even extend beyond bottom dead center.
- a radial thickness of the insulation and/or a thermal resistance of the insulation increases in the axial direction from a combustion chamber in the direction of a crankcase and/or first increases and then decreases again.
- the advantage of an increasing and/or first increasing and then decreasing radial thickness of the insulation and/or the thermal resistance of the insulation in the axial direction from a combustion chamber in the direction of a crankcase is that an oil viscosity is optimally adapted to the operating conditions.
- the insulation is at a maximum of 85-95%, preferably 88-92%, particularly preferably 89-91% of an operating temperature in an area of the running surface in which a top land of a piston is located in conventional cylinder liners or Cylinders located at a top dead center arranged.
- the insulation is defined in operating temperature ranges according to the above feature, since cooling is required in higher operating temperature ranges and heat dissipation must therefore not be reduced.
- At least one insulation is divided into 2-6 sections in the axial direction and/or at least one insulation circumferentially divided into 2-72 sections or subsections thereof.
- Isolation both in the axial and in the circumferential direction can be optimally adapted to the operating conditions in order to influence the oil viscosity on the running surface in such a way that friction is reduced.
- the axial direction is the stroke direction. Sections in the axial direction are separated by webs or insulated to different degrees, and sections in the circumferential direction are also separated by webs or insulated to different degrees.
- the advantage of the webs is a load absorption, which is caused by a piston movement in the cylinder liner or the cylinder. This reduces deformation and extends the life of the cylinder liner or cylinder.
- the insulating material is selected from or consists of the group consisting of plastic, foam glass, titanium, mineral / glass wool, ceramic particles, composite materials, perlite and / or porous or foamed metal such as cast iron, metal spray coatings or alloys.
- the insulating material has a porosity of between 20-80%, preferably 40-80%, particularly preferably 60-80%.
- An insulating effect can easily be adapted to operational requirements due to the porosity.
- the cylinder liner or the cylinder is produced by 3D printing and/or the insulation is produced by spraying metal and ceramic.
- 3D printing can produce any structure on demand with minimal material consumption to be realized. However, preferably only the insulation is printed or sprayed.
- the material of the insulation has no porosity but conducts less heat than a material of the cylinder liner.
- FIG. 1 shows a sectional view of a cylinder liner with thermal insulation
- FIG. 2 shows a sectional view of a cylinder liner with material used in the thermal insulation.
- FIG. 1 shows a sectional view of a cylinder liner according to an embodiment of the invention.
- the cylinder liner has an inside 2, which forms a running surface for a piston, an outside 6 and a surrounding insulation 4.
- a circumferential projection which causes a cylinder liner to be inserted into an engine block with a precise fit.
- a rectangular recess all around which is provided for a fire ring.
- This fire ring prevents a hard carbon deposit from forming on the top land of the piston. This is achieved through a compared to the diameter of the cylinder bore smaller inner diameter of the fire ring. When the piston passes the top dead center, the fire ring scrapes the unwanted carbon deposits from the piston and prevents deposits from forming on the top land.
- a circumferential thermal insulation which is designed as a cavity.
- the cavity has a rectangular cross-section and has wall thicknesses on the inside 2 and on the outside 6 which have the same constant radial thickness.
- the running surface length L and the piston stroke length K can be seen.
- the running surface length L extends in the axial direction over the entire cylinder liner, the piston stroke length K only to the end of the cavity. This means that the bottom dead center corresponds to the bottom of the thermal insulation.
- FIG. 2 shows a sectional view of a cylinder liner according to another embodiment of the invention.
- the cylinder liner has an inside 2, which forms a running surface for a piston, an outside 6 and a peripheral insulation 4.
- a circumferential thermal insulation which is formed by inserting material into a cavity.
- the cavity has a rectangular cross section, is arranged on the outside 6 of the cylinder liner, and has a wall thickness to the inside 2 which has a constant radial thickness.
- the outer diameter of the material insert is equal to the outer diameter of the cylinder liner at the respective location.
- the running surface length L and the piston stroke length K can be seen.
- the running surface length L extends in the axial direction over the entire cylinder liner, the piston stroke length K only to the end of the cavity. This means that the bottom dead center corresponds to the bottom of the thermal insulation.
