Definitions

  • the invention relates to a cylinder head of an internal combustion engine, wherein the cylinder head is medium-cooled and at least per cylinder an annular, the cylinder comprising coolant space and Having coolant lines, wherein in the cylinder head continues Inserted gas exchange valves dominated gas exchange channels are the one the cylinder head combustion chamber side to the cylinder final Penetrate combustion chamber plate.
  • the invention is based on the object, a generic Specify cylinder head, which is optimized by casting.
  • the Gas sequentialkanalkerne held by a Gas crispkanalrechen and the Gas crispkanalrechen has core fingers, which decouple the Auslasskanalwandung effect from the combustion chamber plate.
  • the combustion chamber plate is hemispherical formed, with the spherical side of the combustion chamber wegweis and the Gas monkanalwandungen from the combustion chamber plate emerge flanging out in cylinder head walls. Due to the hemispherical design of the combustion chamber plate is a slight mold release of the cylinder head from the mold given. To this easy removability also carries the feature of Growing the Gas monkanalwandened from the combustion chamber plate at.
  • the invention extends from the combustion chamber plate outgrowing beam approximately centered above the combustion chamber plate in the longitudinal direction of the cylinder head.
  • Beams taken in two coolant lines.
  • the beam is continuous to the cylinder head cover side or paragraph decreasing width.
  • the beam carries to a rigid design of the cylinder head and satisfied with the inclusion of coolant lines simultaneously auxiliary functions. It is due to the chosen training and connection of the beam to the combustion chamber plate again given the ease of releasability.
  • cylinder head screws are on the Corner points of the combustion chamber plate arranged, which at the height of Gas change channel flange upper edge with the cylinder head screw bearing surface to form a plane.
  • the cylinder head bolts whistle over the cylinder head boundary walls (Front and side walls) trough-shaped connected.
  • the cross sections through the cylinder head 1 according to FIGS. 1, 2 and 3 are adjacent to each other in the area of the cylinder head center (FIG. 1) the inlet duct (Fig. 2) and the outlet duct (Fig. 3).
  • the cylinder head 1 has a combustion chamber plate 2, which - by the dashed Illustration marked - from the cylinder block side with the hemispherical side facing the cylinders and the combustion chambers is trained. From this combustion chamber plate 2 grows Beam 4 out, which is approximately centered above the combustion chamber plate 2 extends in the longitudinal direction of the cylinder head and this bar. 4 in particular shown in Figures 2 and 3 to the cylinder head cover side towards a continuously or paragraph decreasing Width up.
  • coolant lines 6a, 6b through Incorporated machining.
  • the coolant lines 6a, 6b are via rising coolant holes 7a, 7b with a Stegbohrung 8 per cylinder connected, wherein the web bore 8 with a coolant annulus connected in the combustion chamber plate. 2 is inserted and wherein such a coolant annulus 9 each Cylinder is assigned and with the appropriate cylinder refrigerator fluidly connected.
  • the coolant is preferably the Lubricating oil of the internal combustion engine.
  • In the respective cylinder center Wide beam 4 are an injection valve bore 10 and a Glühmannkerzenbohrung 11 inserted.
  • crankcase ventilation hole 12 In the area in addition to the coolant line 6b is a crankcase ventilation hole 12 incorporated, the over branching tap holes 13 open into the inlet channels 14. The crankcase gases are fed in via an access hole 15 in the crankcase ventilation hole 12.
  • cylinder head screws 16 At the corners of the combustion chamber plate 2 are a total of four cylinder head screws 16 arranged on the Height of the inlet channel flange upper edge 17 with the cylinder head cover side 5 form a plane.
  • the cylinder head screws whistles 16 are at least partially on support ribs 18 relative to the combustion chamber plate 2 supported and cylinder head boundary walls 19th trough-shaped interconnected.
  • FIG. 5 In the embodiment of FIG. 5 are also stepped trained holes 24 between the individual cylinder sections intended.
  • the training according to the figures 4 to 6 are in particular for a weight reduction of the cylinder head 1 formed.
