Definitions

  • the invention relates to an internal combustion engine with a cylinder head and the use of the cylinder head, the internal combustion engine has a crankcase in which a crankshaft is rotatably supported on which at least one connecting rod is articulated, one in a cylinder movable piston carries, the cylinder under Formation of a combustion chamber is covered by the cylinder head in the Gas exchange valves are let in when actuated with each project their valve disks into the combustion chamber.
  • Such a cylinder head or such an internal combustion engine is known from DE-PS 38 41 355.
  • Proposed solution to increase the displacement are the cylinder distances and enlarged the cylinder diameter. This requires the redesign of all essential internal combustion engine parts and also makes adjustments to the existing production facilities necessary.
  • the internal combustion engine to build with the previous displacement everyone must (previous) internal combustion engine parts to be built so that in addition, a large variety of parts and appropriate stockpiling necessary is.
  • the invention has for its object in an internal combustion engine to realize an increase in displacement in which the variety of parts is low.
  • the cylinder head for internal combustion engines usable with different sized cylinder bores in the form is that the cylinder head for the internal combustion engine with the largest cylinder bore with regard to the arrangement of the cylinder head fasteners and the gas exchange valves as well as the diameter the valve plate and the surrounding valve seat rings is and the the valve plate in the cylinder edge area of the part of the cylinder head interacting with the combustion chamber are sufficient, and that the cylinder head can be fitted with valve seat rings one to a smaller cylinder bore of another internal combustion engine cause adapted reduction of the valve plate diameter.
  • valve seat rings so that the center axis of the valve seat inner diameter eccentrically the center axis of the valve seat ring outer diameter in the direction of the cylinder head center is moved.
  • valve stem guides by the same amount of eccentricity to the center of the cylinder head shifted there. This can be especially true when using of valve stem guide bushes with correspondingly eccentric Bores for the valve stems in relation to the outside diameter can be achieved.
  • valve seat rings In the context of the preferred embodiment of the invention have the valve seat rings but without eccentric Relocation of the different central axes to different seat widths on. This means there is no need for the valve stem guides Change or adjustment to be made and there will be only gas exchange valves matched to the valve seat rings used with reduced valve disc diameters.
  • valve seat rings on the gas exchange channel side one adapted to the gas exchange channels Have a contour. This contour is especially designed that there are no sharp transitions that affect the gas exchange flow could adversely affect.
  • At least one and the same Cylinder head blank for internal combustion engines with different Hole dimensions used. So here are the Clearances between the cylinder head fastenings and the valve stem guide center axes in the longitudinal direction of the cylinder head and in the transverse direction of the cylinder head the same for all hole variants. Details on this have no influence, can of course be changed. So the cylinder head can - regardless of which crankcase it is used - without changes or with the same Tools are processed, but only accordingly different valve seat rings depending on the bore diameter and suitable valves are used. All other attachments of the Cylinder head including the intake pipes and exhaust pipes can be the same. As a result, the manufacturing effort and especially the variety of parts is reduced.
  • valve seat rings have a smaller diameter. So need no valve seat rings with a corresponding transition contour are used but it can be on standard valve seat blanks be resorted to.
  • valve actuation means in the crankcase and / or the cylinder head also the same for the different hole variants. This means that the same parts can be used here, including the camshaft be used.
  • the use or configuration according to the invention of the cylinder head achieved that this for different Bore diameter of the cylinder can be used.
  • the use according to the invention in particular in a Further development of an existing engine series may be advantageous, by first the cylinder head for the internal combustion engine with the increased displacement is developed. This cylinder head can then used on the existing crankcase without changes become.
  • the cylinder 1 shown in FIG. 1, in particular a multi-cylinder In-line or V-type internal combustion engine is of one schematically illustrated cylinder head 2 covered, of which Cylinder head 2, a gas exchange duct 3, a valve seat ring 7 and one partially shown gas exchange valve 4 are shown.
  • the valve stem 5 of the gas exchange valve 4 is in a not shown Valve stem guide guided in the cylinder head 2 while the valve plate 6 with the valve seat ring 7, which is inserted into the cylinder head 2 is cooperating.
  • Location and size of the valve plate 6 and Valve seat rings 7 are dimensioned such that the gas exchange valve 4 the largest possible flow cross-section to the gas exchange channel 3 releases. Accordingly, the gas exchange valve 4 is sufficient up to close to the cylinder surface 8. If a cylinder 1 with a slightly smaller hole size (dashed), the gas exchange valve would no longer be opened and closed can be.
  • a valve seat ring is used Ta with a larger seat ring width in the cylinder head 2 used, at the same time a gas exchange valve 4a with one opposite the gas exchange valve 4 smaller diameter of the valve plate 6a is used.
  • a fluid transition has the valve seat ring 7a a transition contour 9, the one streamlined transition to the gas exchange duct inner wall guaranteed.
  • this valve seat ring 7a with a transition contour 9 can also be adapted when casting the cylinder head 2
  • Gas exchange valve core with smaller ones at least in this area Diameter can be used. The rest is dashed in Fig. 2 the valve seat ring with a smaller seat ring width for one large bore diameter indicated.
  • FIG. 3 and 4 each show a view of the cylinder head 1 on the Combustion chamber side interacting with different bore diameters the cylinder 1, wherein in Fig. 3 an embodiment of the Cylinder head 2 with valve seat rings 7 with a small valve seat ring width and large bore diameter of the cylinder 1 is while Fig. 4 shows an embodiment of the cylinder head 2 with valve seat rings Ta with a large ring width and a smaller bore diameter of cylinder 1 shows.
  • the central bore 10 is an opening in particular for an injection valve, but here also, if necessary Spark plug can be used as the invention for both auto-ignition Internal combustion engines as well as spark-ignited Ottooder Gas internal combustion engines can be used.
  • the distances 11a, 11b the central axes of the gas exchange valves 4, 4a and the distances 12a, 12b of the central axes of the cylinder head attachments (Cylinder head screw whistles) are always the same.
