Definitions

  • ABSTRACT A cylinder structure with a forced cooling fluid system and with a dry cylinder bushing for a water or aircooled piston internal combustion, in which that upper cylinder block portion which is adjacent the cylinder head has annular passage means surrounding the cylinder bore defined by the cylinder block or by a bushing therein while feeding and discharge passage means establish communication between said annular passage means and said cooling fluid system.
  • the present invention relates to a cylinder with dry cylinder sleeve for water-cooled piston internal combustion engines.
  • an object of the present invention to provide means by which the distortion of the cylinder block or the ovalizing of the cylinder bores caused by the above referred to reasons will be avoided also when employing dry cylinder bushings.
  • the cylinder according to the present invention provided with a dry cylinder bushing for water-cooled or air-cooled piston internal combustion engines is characterized primarily in that the upper portion of the cylinder bore which is provided in the cylinder block and is adjacent to the cylinder head or the upper portion of the cylinder bushing has one or more annular passages extending in a direction perpendicular to the longitudinal axis of the cylinder, and is furthermore characterized in that the annular passages respectively communicate through a feeding line and a discharge line with a circulating cooling oil system.
  • This arrangement makes possible an increased heat withdrawal from that portion of the cylinder block and the cylinder bushing which are not or only unsatisfactorily surrounded and cooled by the cooling medium.
  • it will be possible to cool the thermally most stressed portion of the cylinder block in an aimed manner which means to withdraw from this portion such a quantity of heat that the temperature stresses will be completely equalized.
  • the number of the annular passages will vary depending on the magnitude of the section to be cooled.
  • an adjustable throttling device for purposes of controlling the cooling effect, it is suggested to install an adjustable throttling device in the feeding lines for the cooling oil.
  • cooling oil expediently a motor lubricant is employed so that a separate circulating system will not be necessary.
  • the arrangement shown therein comprises a cylinder block 1 and gasket 3 interposed between the cylinder block and the cylinder head 2.
  • the cylinder block 1 has a cylinder bore 4 having inserted therein a cylinder bushing 6 the upper portion of which is provided with a collar 5.
  • the upper portion of the cylinder block 1 is formed by a relatively strong cover plate 7 having cast thereon around the cylinder bore 4 a number of eyes 8 with bores for the connecting screws to connect the cylinder head 2 to the cylinder block 1.
  • the cooling water chambers provided in the cylinder block 1 and in the cylinder head 2 are designated with the reference numerals 9, 9a.
  • the upper portion of the cylinder bore 4 which is adjacent to the cylinder head 2 has an annular passage 10 extending all the way around which through a feeding line 11 and a discharge line 12 communicates with a non-illustrated circulating system for the cooling oil.
  • the collar 5 of the cylinder bushing 6 is provided with an annular passage 13 communicating with a feeding line 14 and a discharge line 15.
  • a throttling device 16 illustrated only diagrammatically is arranged in the feeding lines 11 and 14 for controlling the quantity of oil passing therethrough.
  • a cylinder-piston internal combustion engine with a forced oil circulation cooling system for the engine and an engine lubricating system which includes: a cylinder block having at least one cylinder bore and adapted for cooling therewith, a cylinder head mounted on said cylinder block and adapted for cooling the same as for said cylinder block, that end portion of each said cylinder bore which is adjacent said cylinder head respectively being provided with at least one independent annular passage means, a dry cylinder bushing installed for each respective cylinder bore and having an outer periphery thereof engaging complementary to said cylinder block directly throughout the interrelationship therebetween, and feeding and discharge conduit means communicating only with said passage means and connectable to said cooling system circumcirculation in direct relationship to said dry cylinder bushing.
  • An engine according to claim 2 which includes throttling means interposed in said feeding conduit means of said cooling system.
