Definitions

  • This invention relates to an internal combustion engine having an overhead camshaft to parts of which lubrication is applied by spraying.
  • Lubrication of the interface between each cam-of an overhead camshaft and the component against which the cam operates e.g. valve stem, tappet, rocker, ultimately controlling the aspiration valves of an internal combustion engine, is often effected by spraying.
  • the primary objective of such lubrication is to direct a spray of oil on to an intended area of the cam and/or the component against which the cam directly operates. Effective lubrication of the said interface is mainly dependent on maintaining a sufficient oil spray onto the intended area.
  • the spray is usually emitted from a small hole or jet in a'conduit situated conveniently near the said area and fed from the engine oil pump by pipes and/or oilways in the- cylinder block and head.
  • An average engine oil filter is effective in preventing the flow, in the general oil circuits, of particles which would be injurious to sleeve and rolling bearings.
  • the said pieces may become dislodged purely by the flow of oil in the pipes or oilways, but their incidence is enhanced by the addition of or change to a higher detergent oil than normally used. This is particularly noticeable after the engine has been "flushed out”.
  • An object of the present invention is to provide an O.H.C. internal combustion engine wherein this problem is obviated or minimised.
  • the invention provides an internal combustion engine having an overhead camshaft and an oil supply to apertures for snray lubrication of the camshaft, filter means being provided in said oil flow to prevent or discourage solid material from reaching the spray apertures.
  • the filter should be positioned as far downstream in the oil stream flow as conditions allow; preferably in the final stage, just before the spray holes, in order to minimise the likelihood of blockage.
  • the chosen example of engine of the invention is the British Ford Petrol engine 1600 OHC. or 2000 OHC currently in production.
  • camshaft lubrication oil ascends from the engine oil pumn and filter, both situated low down near the sump, through an oilway in the cylinder block, through a perforation in the cylinder head gasket, through an oilway in the cylinder head into the camshaft centre bearing pedestal from which it passes through a horizontally drilled oilway into the spray pipe assembly (Fig. 2).
  • Fig. 2 is a pictorial view of an assembly consisting of a spray pipe 10, nipple 11 and bracket 12.
  • the assembly is that Ford Part which in U.K. is given No. 1490126 and which in Europe and U.S.A. is marked 70 HM 6578AF and DIFZ-6578A respectively.
  • the assembly is secured by a bolt 13 to the side of the camshaft centre bearing pedestal 14 (Fig. 2a) while the nipple 11 enters a horizontally drilled oilway 15, to receive and transmit oil to the pipe 10. From this noint oil flows into the fore and aft halves of the nine 10a 10b finally to emerge as a spray 16 from each of eight spray holes 17, one spray lubricating each of eight cams (not illustrated).
  • the ends D R of the pipe are sealed, and secured by one bolt each (not shown) to the camshaft fore and aft bearing pedestals (also not shown).
  • Another hazardous feature of this particular engine lies in the fact that the oil passes from an oilway in the cylinder block to an oilway in the cylinder head via the cylinder head gasket. Therefore, very special care must be taken, when changing the cylinder head gasket for maintenance purposes, that foreign matter, such as scrapings does not enter the oilway in either the cylinder block or the cylinder head, for on re-starting the engine, such matter could be carried along by the oil and block one or more of the spray holes.
  • the innermost ends of pine halves 20a, 20b are removed by cutting and the two ends resulting are secured by brazing into two holes, one in each side of a filter case 21 in such a manner that the said ends do not protrude into the inside of the case 21 but the bores of the pipes 20a, 20b connect with the inside of the case. 21.
  • holes for the ends of pipes 2Qa, 20b are punched out to form a short tubular spigot 32 which facilitates brazing of the pipe ends to the case 21 and increases the tolerance in the length to which the pipe halves 20a, 20b have to be cut.
  • Filter components are assembled in the case (1) in the following order:
  • This assembly is then secured to the camshaft centre bearing pedestal by a bolt 30 which may be tightened solidly and yet apply a dimensionally controlled compression to the two '0' ring seals 22, 27 because of the limit to its movement imposed by the solid centre parts of the various components forming a stack around it.
  • a nipple 31 on the case 21 enters the horizontally drilled hole 15 (Fig. 4) in the camshaft centre bearing pedestal 33 to admit oil to the filter case 21.
