- two exhaust valves per cylinder which are indicated by their common outlet 3.
- a receptacle 4 is arranged for a fuel injector or for a spark plug
- each In each case between two adjacent cylinders each have a transverse bulkhead 5 is arranged, through which the inlet / outlet areas of each cylinder are closed from each other.
- each cylinder area of the cylinder head d. H. between each two bulkheads 5 is limited by the flame deck 1.1 and the oil deck 1.2 water jacket is divided by the intermediate deck 1.3 in a lower water jacket part W1 and an upper water jacket part W2, which form the channel arrangement for guiding the cooling water. There are openings provided so that the cooling water from the lower water jacket part W1 in the upper water jacket part W2.
- the cooling water is guided from the inlet side E to the outlet side A of the cylinder head.
- the guidance of the cooling water through the channel arrangements within the water jacket is represented by the flow path 6.
- the cooling water flow flows from the outside below the outlet 3 into the divided by the two bulkheads 5 and the intermediate deck 1.3 lower water jacket part W1 on the flow path 6.1, then below the outlet 3 between the two separate outlets of the exhaust valves in the direction of the receptacle 4,
- a flow passage 7.1 in the intermediate deck 1.3 forms a deflection area and causes a deflection after at the top in the upper water jacket part W2.
- the top view reveals the tip of the arrow P in FIG.
- overhead return flow path 6.2 occurs via an overflow 8, which is arranged substantially in the region of the longitudinal side of the cylinder head, as a tapered flow path 6.1 in the lower water jacket part W1 for the next cylinder head area, as the side view in Fig. 4 shows. In this form, the successive cylinder areas are connected.
- the difference from the embodiment acc. 1 to 4 essentially consists in that the deflection of the cooling water flow from the lower water jacket part W1 to the upper water jacket part W2 via two openings 7.2, which are each provided in immediately adjacent to the bulkheads 5 areas of the intermediate deck 1.3.
- these passage openings 7.2 are arranged approximately in the region of the longitudinal central axis L of the piston internal combustion engine, so that the passage openings in the preparation of the mold can serve to support the core for the upper water jacket part W2.
- this core can be fixed against floating with appropriate design of the mold for the oil deck 1.2.
- the inflowing flow path 6.1 flows as in the embodiment according to. FIGS. 1 to 4 here also the receptacle 4, so that the receptacle 4 and thus arranged in the receptacle 4 injector is reliably cooled.
- Fig. 7 shows schematically the course of the returning flow path 6.2.
- the upper water jacket part W2 of one cylinder is connected to the lower water jacket part W1 of the next following cylinder by an overflow channel 8, as shown in FIG.
- Fig. 8 is a perspective view of a further embodiment of the invention, a cylinder head for a four-cylinder internal combustion engine with its flame deck 1.1 shown.
- the oil deck of the cylinder head is omitted for the sake of clarity, an intermediate deck is not provided.
- each cylinder two intake valves are provided, which are characterized by their common inlet port 2. There are also provided two exhaust valves per cylinder, which are indicated by their common outlet 3. In each case between inlet 2 and outlet 3 is arranged a receptacle 4 for a fuel injector or for a spark plug.
- each have a transverse bulkhead 5 is arranged, through which the inlet / outlet areas of each cylinder are closed from each other.
- the bulkhead 5 is shown here "transparent".
- passage openings are provided through which the cooling water is guided in each case by a cylinder area in the other cylinder area.
- each channel arrangements or flow channels for guiding the cooling water are provided for the area of the outlet port 3 on the one hand and for the region of the inlet port 2 on the other hand, which are cast, for example.
- the channel arrangement is guided so that the cooling water is guided from the inlet side E to the outlet side A of the cylinder head.
- the guidance of the cooling water on the gas outlet side through the channel arrangement is represented by the flow path 6.
- the cooling water flow flows from the outside below the outlet 3 in the divided by the two bulkheads 5 area, then below the outlet 3 between the two separate outlets of the exhaust valves in the direction of the receptacle 4.
- the space between the two outlets of the exhaust valves and Receiving 4 forms a deflection region 7, in which the cooling water is guided from bottom to top on the top of the outlet 3 and flows through the channel arrangement again in the direction of the outside.
- the returning flow path 6.2 of the overhead in the flow direction region is via a transfer port. 8 in the bulkhead 5 connected to the inlet side 6.1 of the next cylinder areas. Because of this cooling water flow results in the region of each outlet 3, a U-shaped cooling water duct, which is guided from outside to inside and back out again, in which case over the connection of each of the return side of the overhead cylinder area with the inlet side of the next underlying cylinder area total results in an approximately helical flow on the outside of the cylinder head, each having a long cross-flow distance.
- the inlet pipe 2 For cooling the inlet pipe 2 corresponding flow channels are provided in the cylinder head, the flow paths corresponding to the lines 9.1 and 9.2 form. Again, 5 corresponding passage openings are provided in the bulkhead, so that a total of a longitudinal flow in the region of the inlet side of the cylinder head, wherein the inlet port 2 are both flowed around on their recording 4 facing as well as on their side facing away from the recording.
- a vote of the respective cooling water volume flows can be effected so that a total of taking into account the lower thermal load on the inlet side on the one hand and the outlet side on the other hand correspondingly different volume flows to the inlet port 2 and to the outlet 3 can be passed and so a total largely uniform cooling of the cylinder head is effected.
- Fig. 9 is a section through a gas outlet valve shown transversely to the longitudinal direction, corresponding to the line IX-IX in Fig. 11.
- Fig. 10 and Fig. 11 are respectively the outlets 3.1 and 3.2 of a gas outlet valve 10 merged into the common outlet 3. This results in the possibility that the cooling water between the two outlets 3.1 and 3.2 can flow into the deflection space 7 before recording 4 and can flow out of the deflection space 7 above the outlet 3, as shown with reference to FIG. 1, back to the outside. This is indicated by the flow arrow 11 in FIGS. 2, 3 and 4.
- the channel arrangement in the region of the outlets 3.1 and 3.2 has respective lateral flow channels 12 and 13, so that branch flows around the outlets 3.1 and 3.2 can flow into the deflection space 7.
- 11 also shows the bulkhead 5 with the associated overflow channel 14, through which the returning flow path 6.2 above the outlet 3 of the preceding cylinder area is connected to the flow path 6.1 of the cylinder area shown at the bottom.
- the bulkhead 5 for the flow paths 9.1 and 9.2 shown in FIG. 8 has corresponding through openings 9.3 and 9.4, which are separated from one another by a flow-guiding element 14.
- the passage opening 9.3 is assigned a guide element 15.1 at least on the outlet side. This causes the inlet port 2 is provided both via an inner flow channel 15 for the flow path 9.1 and via an outer flow channel 16 for the flow path 9.2, so that the inlet port 2 is flowed around both sides as well as the receptacle 4.
- the flow pattern is indicated by the flow arrows.
