Definitions
- the invention relates to a cylinder head for an internal combustion engine having a cooling system with at least one cast radial cooling channel in the region of at least one web between two adjacent mouths of gas exchange channels, the radial cooling channel fluidly connecting a peripheral outer cooling space and a central inner cooling space.
- US 4 889 080 A discloses a cylinder head with cast radial cooling channels, which cooling channels are each arranged between the adjacent mouths of gas exchange channels.
- the cooling channels connect an outer cooling space surrounding the mouths to a central inner cooling space.
- the object of the invention is to provide a cylinder head in which thermally critical areas are optimally cooled and whose cooling system is to be produced with the least possible outlay.
- circumferential outer cooling chamber has the shape of a circular ring, wherein preferably in the region of each ridge between each two gas exchange channels, a radial cooling channel is arranged.
- the radial cooling channels, the inner cooling chamber and the outer cooling chamber in the form of a spoked wheel, wherein the radial cooling channels form the spokes of the wheel.
- the radial cooling channel has different cross sections between the inner cooling space and the outer cooling space, wherein the change of the cross sections is preferably continuous, wherein preferably the radial cooling channel is at least one nozzle-like Has constriction.
- the cross-sectional profile of the radial cooling channels can thus be optimally adapted to the thermal requirements.
- the cross-sectional profile of at least one radial cooling channel is formed swirl-generating.
- a fine-tuning of the heat dissipation can be effected in that the outer annular space has at least one cross-sectional constriction.
- the inner cooling space, the outer cooling space and the radial cooling channels form a first cooling level for cooling the fire deck.
- the cooling system for cooling the gas exchange channels above the firstdeebene has a seconddeebene which is fluidly connected to the firstdeebene, preferably wherein the cooling system has a thirddeebene the seconddeebene, which with the seconddeebene is fluidly connected.
- the cooling chambers are flowed through successively, the flow through both from the first to the third cooling deck, as well as vice versa from the third to the first cooling space is possible.
- At least one mouth of a gas exchange channel preferably the mouth of an outlet channel
- a preferably cast ring cooling chamber which annular cooling space is flow-connected to the inner cooling space and / or the outer cooling space.
- the annular cooling chambers around the mouths of the outlet channels ensure a particularly good heat dissipation from the thermally highly stressed areas.
- FIG. 1 shows a core package of a water jacket of a cylinder head according to the invention in an oblique view
- FIG. 3 shows a core packet of the first and the seconddeebene in a section along the line III-III in Fig. 1,
- FIG. 4 shows a cylinder head according to the invention in a section along the line IV-IV in Figure 5, top view of the firstdeebene,
- FIG. 5 shows the cylinder head in a section along the line V-V in Fig. 4 and Fig. 6 shows the cylinder head in a section along the line VI-VI in Fig. 4,
- FIG. 7 shows the cylinder head in a section along the line YII-YII in Fig. 4,
- Fig. 8 shows a core package for the cylinder in a section along the line VIII-VIII in Fig. 2 and 9 shows the core package for the cylinder in a section along the line IX-IX in Fig. 2nd
- a cooling system 38 is provided with a first, a second and a third cooling level 5, 6 and 7, wherein the superimposed cooling level 5, 6, 7 are fluidly connected to each other.
- the corresponding core packages are designated in FIGS. 1 to 3 with 5a, 6a and 7a.
- the first cooling level 5 serves to cool the fire deck 8, in particular to cool areas of high thermal load 9, 10, 11, 12 between the openings 13, 14, 15 and 16 of the inlet and outlet channels 2.
- the first cooling level 5 in this case has an inner central cooling space 17 for the injection device 14 and a circumferential outer cooling channel 18 formed as an annular channel, as well as radial cooling channels 19, 20, 21 and 22, which connect the inner and outer cooling chambers 17, 18 to one another.
- the radial cooling channels 19, 20, 21 and 22 have different cross-sections depending on the radius, wherein the continuous cross-sectional profile is adapted to the thermal requirements.
- a nozzle-like constriction 23, 24, 25 and 26 is provided in the region of the webs 9, 10, 11, 12 in each case in order to increase the flow velocity of the coolant.
- annular cooling chambers 27, 28 are provided around the orifices 15, 16 of the outlet channels, which are flow-connected via connecting channels 29, 30 with the inner cooling chamber 17 and the outer cooling chamber 18.
- the coolant flows from a distributor strip, not shown, coming into the outer cooling chamber 18 and from there through the radial cooling channels 19, 20, 21, 22 into the inner cooling chamber 17 the coolant flows from the outer cooling chamber 18 via the connecting channels 29, 30 in the mouths 15, 16 surrounding annular cooling chambers 27 and 28, and passes from here into the central inner cooler chamber 17 to the injector 4. From the inner cooling chamber 17, the coolant continues to flow through an annular gap 32 in an intermediate deck 33 around the injection device 4 into the second cooling level 6 and flows through overflow openings 34 into the third cooling level 7, as indicated in FIGS. 5 and 6. From the third cooling level 7, the coolant enters a collection bar, not shown.
- the outer cooling space 18 in the cylinder head 1 can also be dial open to the outside. In the assembled state then the outer cooling chamber 18 is limited to above the cylinder head plane 36 raised walls of the cylinder block.
- FIGS. 8 and 9 show core packages of the cylinder head, the cores 2a of the gas exchange channels 2 being mounted in the core 5a of the first cooling plane 5.
