Definitions

  • the invention relates to an internal combustion engine having a cylinder head, a cylinder head cover, a seal arranged between the cylinder head and the cylinder head cover, wherein the cylinder head and the cylinder head cover are connected to each other via a screw, and one or more rail holders.
  • the present invention seeks to provide an improved generic internal combustion engine.
  • this should be characterized by lower production costs.
  • the one or more rail holder with those fittings, with which the cylinder head cover and the cylinder head are connected is bolted to the cylinder head.
  • Cylinder head cover is supported, in particular directly or directly adjacent supports.
  • an advantageous and, in particular, large-area transmission of the force applied to the screwing via the (preferably made of a metal and in particular steel) rail holder can be achieved on the (in this area preferably made of a (for example injection-molded) plastic) cylinder head cover.
  • Cylinder head cover can be kept low, but it can also be an advantageous because large-area and thus relatively uniform load arranged between the cylinder head cover and the cylinder head and defined by the Verschraubungs practice deformed seal can be achieved.
  • the deformation of the seal is limited as a result of the screw from the rail holder.
  • Such a limitation may be useful in order not to damage the possibly made of plastic cylinder head cover by excessive bolting forces.
  • the limitation of the deformation path can preferably be achieved in that the rail holder has a web which rests after reaching the intended deformation of the seal on the cylinder head, in particular rests tightly or immediately adjacent.
  • the web may be preferably tubular and receive in its interior a portion of the screw.
  • the web is preferably an integral part of the (preferably one-piece) rail holder, whereby a simple mountability is achieved and also benefits to achieve a required for the deformation of the seal tolerance can be achieved.
  • this solution has in principle the disadvantage that the sleeve must be mounted separately, which increases the production costs.
  • an additional, to be observed in the manufacture of the components dimension requires increased manufacturing accuracy over the preferred integral design of the web to achieve the required tolerance.
  • FIG. 1 shows a cross section through part of an embodiment of a
  • the internal combustion engine according to the invention comprises a cylinder head 10, which may be manufactured as a cast component, in particular made of aluminum or gray cast iron.
  • the upper end of the cylinder head 10 is closed by a cylinder head cover 12, which - at least for the most part - is made of plastic. The between the
  • Cylinder head cover 12 and the cylinder head 10 formed gap is sealed by a (flat) seal 14.
  • This has peripherally extending projections 16 in the edge region, which engage in corresponding receptacles of the cylinder head cover 12.
  • each of these rail holders 22 includes a boom 26 having a through hole that serves to receive a portion of the shank of the screw 18.
  • the head of the screw 18 can be supported on the top of the boom 26.
