Definitions

  • the invention relates to a method for lubricating a reciprocating internal combustion engine with the features of the preamble of the claim.
  • the invention is based on the object of changing the lubrication method in a reciprocating piston internal combustion engine of the type mentioned in such a way that, in addition to reducing the piston ring wear, it also takes into account the corrosion attack due to the combustion of heavier oils and the wear in the lower cylinder area.
  • this object is achieved by the features of the characterizing part of the patent claim.
  • These measures make it possible to individually adapt the lubricating oil supply to each lubrication area according to the different operating conditions in these two areas, for example by adding a more expensive lubricating oil with a high TBN (total base number) to the upper row of holes and a cheaper lubricating oil with the lower row of holes a lower TBN or a higher viscosity than the upper row of holes, each in the appropriate adjustable amount.
  • TBN total base number
  • a piston 2 is guided up and down in a cylinder insert 1, which is arranged in a known manner in a cylinder block of a reciprocating piston internal combustion engine of the diesel type and not shown.
  • the piston 2 is in the top dead center position.
  • the piston 2 is provided with a plurality of piston rings 3, which are accommodated in a known manner in ring grooves of the piston and bear with their outer peripheral surface on the inner circumferential surface 1 'of the cylinder insert 1.
  • a series of lubricating oil bores 5 are provided which penetrate the cylinder insert and end in a plane lying essentially perpendicular to the longitudinal axis of the cylinder insert on the lateral surface 1 '.
  • the area in which the lubricating oil bores 5 are arranged lies below the uppermost piston ring 3 when the piston 2 is in its top dead center position. The limits of this range are between 5 and 18% of the piston stroke.
  • the second lubrication area formed by these lubricating oil bores 6 has its limits between 20 and 40% of the piston stroke.
  • the lubricating oil holes 5 and 6 open into lubrication grooves 5 'and 6', which in the inner lateral surface 1 'of Cylinder insert 1 are incorporated and extend transversely to the direction of movement of the piston 2.
  • a separate lubricating oil supply 7 or 8 is connected to each row of the lubricating oil bores 5 and 6 and each of these contains an adjusting element 9 or 10 in order to be able to individually adjust the amount of lubricating oil to be supplied to the associated row of lubricating oil holes.
