Definitions
- a cylinder head for a piston internal combustion engine in which the areas of the cylinder head which contain cooling water and which are enclosed by a flame deck and an upper deck are continuous through an intermediate wall in a lower area leading to cooling water delimited by the flame deck and is subdivided into an upper area guiding cooling water delimited by the upper deck, the lower and the upper area guiding cooling water not having any cross-connections for a cooling water exchange between the lower and the upper area, in order to be able to conduct separate cooling water flows over the cylinder head.
- This does result in a stiffening of the cylinder head in relation to the bending stresses mentioned above due to the increased internal cylinder pressures.
- the manufacture of such a cylinder head presents casting problems.
- the separate cooling water routing in the cylinder head can also cause adverse thermal stresses in the cylinder head due to temperature differences due to the lack of cross exchange of cooling water between the hotter lower and the less hot upper area.
- the invention has for its object to provide a cylinder head which on the one hand has a high degree of dimensional stability, on the other hand leads to a substantially uniform cooling through the cooling water passed through.
- This object is achieved according to the invention with a cylinder head through which cooling water flows longitudinally or transversely, with cooling water inlet and cooling water outlet for a water-cooled multi-cylinder piston internal combustion engine, with a cavity enclosed by a flame deck and an upper deck, each of which
- Cylinder is penetrated by a pipe for the use of a fuel injector and at least one gas inlet duct and at least one gas outlet duct and pipes for the cylinder head bolts, the free areas between the flame deck and the upper deck serving as cooling water guides, and the areas leading in part of the cooling water Intermediate webs is provided. It has been shown that the arrangement of such intermediate webs is sufficient to bring about the required stiffening of the cylinder head. Since the individual intermediate webs are arranged at a distance from one another, sufficiently large openings remain which effect a good exchange between the cooling water flowing near the flame deck and the cooling water flowing past the upper deck.
- the intermediate webs are flat and are aligned with their larger surface substantially parallel to the flame deck.
- This embodiment has the advantage that the intermediate webs can be made relatively thin-walled, but with sufficient extension they have a sufficient cross-section to achieve the desired strength and thus the desired stiffening. This also ensures that the flow resistance can be kept low.
- Another advantage is that the intermediate webs, when they are connected in the area of the gas outlet channels and the gas inlet channels, the cooling surface for the Increase gas outlet channels or cause heat transfer from the gas outlet channels to the gas inlet channels to a small extent.
- the front edge and / or the rear edge of at least some of the intermediate webs can at the same time perform a guiding function by appropriate shaping, so that areas with higher thermal loads, in particular on the flame deck, are more strongly involved Flow of cooling water.
- FIG. 1 shows a vertical cross section through a cylinder head according to FIG. the line I-I in Fig. 2,
- Fig. 2 shows a horizontal section through a section of a cylinder head. the line II-II in Fig. 1,
- FIG. 3 shows a horizontal section corresponding to FIG. 2 with a different arrangement for intermediate webs
- Fig. 4 shows a horizontal section. 2 with a further design example for the intermediate webs
- Fig. 5 based on the example of the embodiment. 3 shows the principle of a longitudinal flow
- the cross section shown extremely schematically in FIG. 1 through a cylinder head 1 for a multi-cylinder piston internal combustion engine for the diesel process essentially has a flame deck 2 and an upper deck 3, which enclose a cavity, which is denoted by an unspecified one Cooling water inlet and with an unspecified cooling water outlet is connected and through which cooling water flows.
- the flame deck 2 closes an only indicated cylinder block ZB with the cylinders Z on the top.
- the cavity is penetrated in each case in the cylinder areas by at least one gas inlet channel 4 and at least one gas outlet channel 5 as well as a pipe 6 for a fuel injector and pipes 7 for the cylinder head screws.
- the cylinder head for a piston internal combustion engine working according to the Otto process has a similar structure.
- the areas 8.1, 8.2, 8.3, 8.4 and 8.5 which remain free between the flame deck 2 and the upper deck 3 serve as cooling water guides which, depending on the connection with the cooling water inlet and the cooling water outlet, can be flowed through longitudinally or transversely.
- FIG. 2 shows that in each case intermediate webs 9 are arranged in a part of the water-carrying areas, the surface of which are highlighted in FIG. 2 as well as in FIG. 3 by cross hatching.
- the intermediate webs 9 run approximately parallel to the flame deck 2.
- the intermediate webs 9 each extend between the gas inlet channels 4 and the gas outlet channels 5 and thus stiffen the area directly above the cylinders Z indicated by a chain line.
- FIG. 3 shows another embodiment in a section corresponding to FIG. 2, in which intermediate webs 9 are provided in the intermediate regions between two adjacent cylinders Z, respectively.
- the front edges 11 and / or the rear edges 12 of the intermediate webs 9 can then be designed in such a way that they perform a guiding function for the cooling water in relation to the direction of flow, so that For areas of the flame deck that are subject to high thermal loads, a targeted guidance of the cooling water and / or a targeted exchange of cooling water between areas near the flame deck and areas near the upper deck is effected.
- stiffening ribs 10 are provided which run in the plane of the intermediate webs 9 at least over part of the walls delimiting the cavity and limit openings 13 between adjacent intermediate webs 9. It is expedient here if the stiffening ribs 10 merge into the intermediate webs. Since the cylinder head of a multi-cylinder internal combustion engine is exposed to very complex mechanical loads, i. H.
- the stiffening ribs 10 delimiting the openings 13 form a substantial stiffening on the walls delimiting the cavity, for example the gas inlet ducts and the gas outlet ducts.
- Fig. 5 is according to the embodiment. 3 the principle of a longitudinal flow through the cooling water through the cooling water-carrying regions 8 is indicated.
- the arrow L E shows that the cooling water emerges at the opposite end, so that the cylinder head is flowed through lengthways.
- the intermediate webs are flowed through on their side facing the upper deck 3, with cooling water exchange between the falling deck side and the upper deck side taking place in each case above the space between two successive intermediate webs.
- Fig. 3 indicated the principle of the cross-flow of the cooling water through the cooling water-carrying area 8.
- the arrows Q E show that on the side of the gas outlet channels 5 from a longitudinal channel 14 as an inlet, which can be integrated in the cylinder head or the engine block, cooling water transversely to the longitudinal direction of the cylinder head 1 into the cooling water-carrying areas 8, one cylinder each 7 assigned, entry.
- the arrows Q E indicate this only schematically.
- the exact position with respect to the respective cylinder Z depends on the respective structural conditions, in particular on the design of the gas outlet channels 5 and corresponding to the gas inlet channels 4.
- a collecting duct 15 is correspondingly provided as an outlet, in which the cooling water emerges from the individual regions each assigned to a cylinder. This is indicated schematically by the arrows Q A.
- the actual position depends on the design conditions.
- transverse flow too, a cooling water exchange can take place over the free space between adjacent webs. Since there are no so-called bulkheads in the cylinder head between the areas assigned to the individual cylinders, the transverse flow can be set freely, so that flow components pointing in the longitudinal direction can be present in partial areas.
