Definitions

  • the invention relates according to the preamble of claim 1 to a liquid-cooled cross-flow cylinder head for internal combustion engines with cylinders arranged in series, wherein the cylinder head with integrated control housing between a cylinder head floor and a control housing side top wall comprises a limited side walls coolant space, wherein the cylinder head floor from the coolant space and the top wall passing through screw pipes and oil drainage channels and arranged about cylinder-centered shaft pipes for spark plugs or injection nozzles are provided and further the coolant space is divided by means of transverse walls between diametric screw pipes.
  • Such a cylinder head is for example from the DE 38 38 953 C2 known, the transverse walls between diametrical screw pipes the height of the coolant space to pass through to the flat top wall and further to the transverse walls in the connecting planes querab adjacent shaft pipes before the manhole tubes each longitudinal end walls are provided in a cross-flow of the cylinder head of the deflection of the coolant in Serve direction of the shaft tubes and the adjacent areas of the cylinder head floor, which are arranged on this additional guide ribs.
  • a disadvantage of this known cylinder head is the complex casting design and the large-scale coolant space training.
  • the invention has the object of providing a generic cylinder head casting technology easier to design with high rigidity and targeted coolant flow at least in cross flow.
  • a particularly rigid cylinder head is achieved in an advantageous manner in casting technology simpler embodiment by means of connected to the cylinder head floor via transverse walls wells, being achieved in a further advantageous manner with the elimination of separate guide ribs for influencing the flow better venting of the cylinder head.
  • the wells may be formed for a cylinder head as separate components, but they are preferably integrally formed in a further development of the invention by means of casting training, a trough - seen in plan view - extends from each screw pipe in the direction of a connecting plane of the transverse adjacent pit pipes and serves as a directed to the shaft tubes flow guidance.
  • a coolant cross-flow of the cylinder head is preferably supported.
  • a longitudinal flow can be achieved in that the transverse wall between the cylinder head floor and trough in the longitudinal direction of the cylinder head having pointing flow opening. This can be achieved near the ground, additional flow of the manhole pipes.
  • an additional stiffening of the cylinder head is achieved in that the trough is provided along its opening edge with a projecting over the top wall stiffening web.
  • a liquid-cooled cross-flow cylinder head 1 for a not shown internal combustion engine with cylinders arranged in series comprises an integrated control housing 2 and between a cylinder head bottom 3 and a control housing side cover wall 4 of side walls 5 limited coolant space 6. Further, the cylinder head 1 is designed such that from the cylinder head floor 3 from the coolant chamber 6 and the top wall 4 passing through screw pipes 7 and ⁇ Iablaufkanäle 8 and approximately cylinder-centered shaft pipes 9 are provided for spark plugs or injectors. Next, the coolant chamber 6 is divided by means of transverse walls 10 between diametric screw pipes 7.
  • a trough 11 is arranged in the top wall 4 between diametrical screw pipes 7 and each querab adjacent shaft tubes 9 , which by means of a transverse wall 10 between the diametric screw pipes 7 and the cylinder head floor 3 is connected, wherein from the transverse wall 10 in the direction of the top wall 4 rising wall sections 11 'and 11 "of the trough 11 serve as flow control surfaces.
  • the trough 11 is integrally formed by casting training in the cylinder head 1, wherein the trough 11 - seen in plan view - of each screw pipe 7 in the direction of a connecting plane 12 - Figure 3 - the querab adjacent shaft pipes. 9 extended and serves as a directed to the shaft tubes 9 flow guidance.
  • the trough 11 is connected to the oil drain channel 8 or 8 'via a separate channel 13.
  • the trough 11 with the screw pipe 7 integrally formed with an oil drain passage 8 via a screw pipe 7 passing through arranged Channel 13 in conjunction, wherein the screw pipe 7 surrounds a cylinder head screw, not shown with play.
  • an inlet opening 14 of the separate channel 13 is arranged in the trough 11 corresponding to the installation position of the cylinder head 1.
  • FIG. 3 a shows an oil drainage channel 8 formed in one piece with a screw pipe 7, while FIG. 3 b shows an oil drainage channel 8 'arranged freestanding from the screwing pipe 7.
  • each stiffening web 16 in its course across the cylinder head 1 approximately corresponds to the course of the wall sections shown in Figure 3 11 'and 11 "of the trough 11, each of the Verste Trentsstege 16 contributes to the stiffening of the cylinder head 1 in the longitudinal and transverse directions.
  • the invention is suitable for two-valve and multi-valve cylinder heads for in-line or V-engines.
