Definitions

  • An internal combustion engine having a cylinder head mounted on a cylinder block, is provided with means for supporting a cylinder liner therein, which comprises a yieldable spacer for compensating for excess loads exerted on the liner imparted by torqueing of the head to the block, together with a semi-resilient support sleeve, which acts as a stiff spring to accommodate thermal expansion and contraction of the cylinder liner occurring during normal operating cycles of the engine.
  • the yieldable spacer is chevron-shaped in cross section and has a resilient annular positioner member associated therewith.
  • Radial movementpreventing means in the form of an annular flange on the cylinder liner, closely fitted within a bore in the block, is also provided.
  • the radial movement-preventing means is an annular flange on the outer periphery of the cylinder liner adjacent its topmost end, having a plurality of circumferentiallyspaced slots therein, and fitted within the cylinder bore.
  • This invention relates to a cylinder liner support means for internal combustion engines. More particularly, this invention relates to such a support means comprising a yieldable spacer in combination with a somewhat resilient support sleeve, which are disposed between the engine block and the cylinder liner.
  • engine blocks utilizing cylinder liners therein are usually provided with counterbores in the top deck portion of the engine block for receiving flanges of the cylinder liners for mounting and location thereof.
  • the uppermost face of each cylinder liner flange projects slightly above the top deck portion plane to enable a head gasket to be compressed between the cylinder head and the cylinder liner flange and thereby provide an effective seal for combustion gases generated within the cylinder.
  • a problem arises in that, with engines having a plurality of cylinders and corresponding cylinder liners, machining tolerances of the counterbores and liner flanges results in some of the liners projecting above the top deck portion plane further than others.
  • the invention provides in an internal combustion engine having a cylinder head mounted on a cylinder block, a means for supporting a cylinder liner.
  • the cylinder liner support means comprise a support sleeve circumscribing a reduced diameter portion of the cylinder liner and a yieldable spacer also circumscribing the reduced diameter portion.
  • the support sleeve and yieldable spacer accommodate excess loads on and thermal cycling of the cylinder liner.
  • Means for preventing radial movement of the cylinder liner in the form of a radial flange are also .provided.
  • FIG. 1 is an enlarged cross-sectional vertical elevation view ofa cylinder liner support and means for preventing radial movement of this invention shown in an internal combustion engine;
  • FIG. 2 is an alternate embodiment of the device shown in FIG. 1, which differs only in having an alternate means for preventing radial misalignment;
  • FIG. 3 is a cross-sectional view taken along lines 11-11 in FIG. 2.
  • a cylinder liner support means of this invention is shown generally at 10, within an internal combustion engine partially shown at 12.
  • the engine comprises a head portion partially shown at 14 mounted on an engine block, partially shown at 16.
  • a head gasket 20 is Intermediate the head portion 14 and the top deck portion 18 of the engine block 16.
  • the engine block includes a lower wall 22 which partially defines a crankcase cavity 24 for containing the crankshaft partially shown at 26.
  • the engine block also includes a cast shelf 28 disposed intermediate the top deck portion 16 and lower wall portion 22.
  • a cylinder bore 30 is formed within the block by a plurality of concentric bores 32, 34 and 36 individually formed in the top deck, cast shelf, and lower wall, respectively.
  • a cylinder liner 38 Received within the bores in close-fitting relation therewith is a cylinder liner 38 of generally cylindrical configuration, having a reduced diameter portion 40 at the lower end thereof which defines an annular shoulder 42 therearound. A second reduced diameter portion 44 is provided at the lowermost end of the cylinder liner 38.
  • the liner itself defines a piston bore 46 for reciprocatingly conataining piston 48 which is connected to connecting rod 50.
  • a counterbore 52 is contained in lower wall 22 and de fines a radially extending shelf 54.
  • a plurality of coolant passages 56 are formed in top deck portion 18 in alignment with similar passages 58 in the cylinder head and gasket 14 and 20. Additional passages 60 are formed in the cast shelf 28.
  • the cylinder head 14 is secured to the engine block by conventional means such as bolts (not shown).
  • the cylinder liner 38 which may be of cast iron, extends through bores 32, 34 and 36 to form a pair of annular coolant cavities 62, 64 circumscribing a cylinder liner on opposite sides of cast shelf 28.
  • An annular re cess 66 is provided on the uppermost end of the cylinder liner adjacent to the cylinder head 14 for the purpose of receiving a matching portion of the head gasket for sealingly separating the coolant from combustion chamber 68 formed by head 14, piston 48 and cylinder liner 38.
  • Intermediate the upper and lower ends of the cylinder liner is a radially extending annular flange 70, closely fitted within bore 34 for the purpose of preventing radial movement of the liner.
  • the cylinder liner support means 10 comprises a similar resilient support sleeve 72 circumscribing a reduced diameter portion 40 of the cylinder liner.
  • Support sleeve 72 has a peripheral groove 74 therearound and is relatively thin compared to the thickness of the cylinder liner.
  • the sleeve which may be made of metal, is relatively thin-walled so that it has a lower spring rate relative to the thicker cylinder liner.
  • the support means further comprises a chevronshaped yieldable spacer 76 which may be made of resilient material. Disposed between the spacer and the cylinder liner is a resilient annular ring member 78, which may be made of rubber or other resilient material, for the purpose of radially positioning the spacer. The spacer also serves as a seal to prevent coolant from entering the crankcase cavity 24.
  • the sleeve acts as a stiff spring and serves to continuously urge the liner against the head gasket as the engine cools and the liner contracts. This stiff spring effect causes the support sleeve to act in a resilient manner.
  • FIGS. 2 and 3 there is therein illustrated an alternate embodiment which differs from the primary embodiment shown in FIG. 1 only in that the radial movement of the liner is prevented in a different manner.
  • no intermediate cast shelf is provided. Rather, radial movement is prevented by an annular guide flange 80 on the outer periphery of the cylinder liner 38' adjacent to its topmost end.
  • This flange 80 is closely fitted within bore 32, adjacent top deck portion 18.
  • a plurality of axially aligned, circumferentially spaced slots 82 are formed in the flange 80 to permit free coolant flow to passages 56 and 58, in the top deck and head portions, respectively.
  • a cylinder head mounted on a cylinder block, said block defining a top deck portion, a cylinder bore in said cylinder block, a generally cylindrical cylinder liner disposed within said cylinder bore, a reduced diameter portion of said cylinder liner defining an annular shoulder intermediate said top deck and said shelf, means for supporting said cylinder liner comprising a support sleeve circumscribing said reduced diameter portion of said cylinder liner having an end thereof in abutment with said annular shoulder, wherein said support sleeve is relatively thin walled with respect to said cylinder liner whereby it possesses a relatively lower spring rate with respect to said sleeve, and further including means for preventing radial movement of said cylinder liner in said block comprising a shelf in said block intermediate said top deck and lower wall defining a bore, and an annular flange on said cylinder liner closely fitted within said last-named bore.
  • a cylinder head mounted on a cylinder block, said block defining a top deck portion, a cylinder bore in said cylinder block, a cavity in said block including a lower wall defining a shelf located intermediate the top deck and the lower wall, a generally cylindrical cylinder liner disposed within said cylinder bore, a reduced diameter portion of said cylinder liner defining an annular shoulder intermediate said top deck and said shelf and means for supporting said cylinder liner comprising a support sleeve circumscribing said reduced diameter portion of said cylinder liner having an end thereof in abutment with said annular shoulder, and a yieldable spacer circumscribing said reduced diameter portion and in abutment with the other end of said support sleeve and said shelf whereby excess loads on and thermal cycling of said cylinder liner are accommodated, wherein said support sleeve is relatively thin walled with respect to said cylinder liner whereby it possesses a relatively lower spring rate with respect to said sleeve,
