Definitions

  • the present invention relates to a cylinder housing with dry cylinder liners especially for internal combustionengines.
  • Such types of liners are normally oversize inder liners and of the cylinder bores. This makes necessary repeated after'finishing operations. Further form-changes lead to the-formation of gaps and hollow spaces between the cylinder bore and the cylinder liner. In internal combustion engines hot gasespenetrate from the. combustion space into these hollow spaces andattackthesurfaces thereof.
  • a further disadvantage are the large forces which have to be applied during the disassembly of the cylinder liners.
  • the cylinder bores may be, considerably damaged'by the strong frictionconnected therewith.
  • a press is not necessary therefor. Under certain circumstances, already asingle hammer blow on an emplaced interme diate platesuffices in order to drive the cylinder liner intoitsend position within the cylinder bore. Stresses and subsequent deformations of the cylinder liner resulting therefrom are avoided by the slight pressing-in force or pressure.
  • the further significant advantage results therefrom that the cylinder liners can be finishmachined already prior to installation so that afterfinishing. operations may be dispensed with.
  • a good abutment of the cylinder liner. in the cylinder bore with sufficient adhesion and favorable heat transfer is achieved according .to the present invention in that also the cylinder bore tapers or converges in a conical shape.
  • the cylinder liner additionally centers itself automatically during the introduction into the cylinder bore so that any canting is precluded.
  • the angle of inclination of the outer surface-of the cylinder liner is larger than the angle'of inclination of the housingbore.
  • the abutment pressure of the cylinder liner is largest at the hottest and most heavily stressed place within the area of the outer wall of the cylinder housing.
  • the outer surface of the cylinder liner and/or the cylinder bore may be provided with a soft metal layer, for example, made from tin. Small surface inaccuracies are compensated thereby and the heat. transfer between cylinder liner and cylinder bore is considerably improved. ln-contradistinction to the bushes with a cylindrical .outer surface in which such a layer is destroyed during the pressing-in operation and is stripped off for the most part, this layer remains preserved with the cylinder liner in accordance with the present invention adapted to be inserted easily.
  • I Accordingly, it is an objectof the present invention to provide'a cylinder housing with dry cylinder liners which obviates the disadvantages and drawbacks encountered in the prior art. 1 I i Another object of the present invention resides in a cylinder housing with dry cylinder liners which eliminates the need for large forces to assemble anddisassemble the cylinder liners in and from the cylinder bores. i r A further object of the presentinvention resides in a cylinder housing with dry cylinder liners whichpractically completely eliminates the danger of wear, ovalization and warping of the cylinder lizners and/or cylinder bores. I
  • Still another object of the present invention resides in'a cylinder, housing with dry cylinder liners which not. only greatly reduces the amount of machining operations necessary but also reduces the. price for the manufacture and assembly thereof.
  • a further object of thepresent invention resides in a cylinder housing with dry cylinder liners which eliminates special forms for the liner and/or the'cylinder bore, which avoids stresses and which improves the heat transfer.
  • The'single figure is a cross-sectionalview through a cylinder housing of a piston internal combustion engine with a dry cylinder liner in accordance with thepresent invention.
  • reference numeral 1 designates therein the cylinder bore of a cylinder housing 2 into which is inserted a dry cylinder liner 3.
  • the flangeless end face 4 of the cylinder liner 3 is disposed in one and the same plane with the outer walls of the cylinder housing 2.
  • the outersurface 6 of the cylinder liner 3 tapers conically in the inward direction from the end face 4 thereof.
  • the angle of inclination a of the outer surface 6 amounts to about 25 minutes.
  • the cylinder bore 1 also tapers conically in the inward direction.
  • the angle of inclination a of the outer surface 6 of the cylinder liner 3 is about 4 minutes larger than the angle ofinclination B of the cylinder bore 1.
  • Preferred dimensions for the tapering of the outer surface of the cylinder liner 3 lie between a cone of about 1 50 to a cone of about 1 125.
  • the fine-finished or machined outer surface 6 is provided with a tin coating having a thickness of about five thousandths of a millimeter.
  • the cylinder liner 3 can be secured rapidly and with out costly auxiliary means in the cylinder housing 2. For this purpose, one introduces the cylinder liner 3 into the cylinder bore 1 until it abuts with its outer surface 6 at the upper edge thereof. The cylinder liner 3 therefore immerses almost with its entire length into the cylinder bore 1. As a result of the conical construction of the cylinder bore 1 and of the cylinder liner 3, the latter centers itself. One places an intermediate plate (not shown) on the end face 4 of the cylinder liner 3 which projects, for example, with l/lO of its length, and one is able to press-in the cylinder liner 3 thereafter with a relatively small pressure until its end face 4 is flush with the outer wall 5 of the cylinder housing 2.
  • the end face 4 of the cylinder liner 3 may also project by a small amount, for example, by a tenth of a millimeter, beyond the outer wall 5 of the cylinder housing 2. These differences in height may be compensated for in the assembled internal combustion engines by the seal inserted between the cylinder housing 2 and the cylinder head.
  • the cylinder liner 3 is securely seated in the cylinder housing 2 after the pressing-in operation. its outer surface 6 abuts over the entire length or nearly over the entire length thereof in the cylinder bore 1. The abutment pressure is thereby largest in the most strongly loaded zone withinthe area of the outer wall 6 of the cylinder housing 2 and decreases from there uniformly in the inward direction.
  • the soft tin layer at the outer surface 6 of the cylinder liner 3 equalizes any still existing, local form-deviations and improves the heat transfer from the cylinder liner 3 to the cylinder housing 2.
  • any other soft metal for example, aluminum or copper may also be applied onto the outer surface of the cylinder liner 3.
  • the cylinder liner 3 becomes disengaged readily from the cylinder bore 1 after overcoming an initial resistance and can be pulled out of the cylinder housing 2 simply and without damage to the outer surface 6 or to the cylinder bore 1.
  • An arrangement for an internal combustion engine comprising: a cylinder housing having a bore delimited by inwardly facing bore walls, and a cylinder liner having outwardly facing liner wall surfaces, wherein said liner is positioned in said bore, wherein both said bore walls and liner wall surfaces are conically tapered with the angle of inclination of said bore walls with respect to a longitudinally extending central bore axis being different than the angle of inclination of said liner wall surfaces with respect to said bore axis, and wherein said liner is held in position in said bore exclusively by frictional engagement of said bore walls and liner wall surfaces.
  • an upper end of said liner has a larger cross-sectional size than an opposite lower end of said liner such that the liner can be inserted from above into said bore.
  • an upper end of said liner has a larger cross-sectional size than an opposite lower end of saidliner such that the liner can be inserted from above into said bore.
