- a cylinder partition made of cast material is between the cylinder recesses formed, the minimum width indicated by the arrows is.
- the initially constant width of the salt core 8 decreases from its Ends at a transverse axis 14 crossing the cylinder axes perpendicularly and reached with this axis a width of 1 mm, while the outer sections of the salt core in the embodiment have a width of 2.5 mm.
- the minimum, through cast material formed wall thickness of the cylinder partition at 13 is inclusive of minimum channel width 2.5 mm.
- Gray cast iron bushings to be cast into the engine block are not shown, so that the total web width is 5.5 mm.
- the salt core 8 has one rectangular cross section, with the long rectangular side of the cross section extends perpendicular to the cylinder axes and 4 mm in the exemplary embodiment shown is.
- the salt core 8 is made of NaCl, which has a melting point above Temperature of the liquid aluminum casting used to manufacture the engine block lies. Depending on the casting material, other salts and salt mixtures can be used.
- the salt core 8 is in the embodiment shown by pressing and subsequent Sintered.
- the salt core is removed from the hot water Cast part detached. and it creates the cooling jacket sections on both sides of the Cooling channel connecting the row of cylinders, which is only through a continuous cast material skin is limited, which gives the thin cylinder partition a high strength.
- the cooling channel ensures sufficient heat dissipation and thus high heat resistance of the engine made from the engine block.
- the salt core expands, the grooves 6, 7 with it Provide enough space for this expansion.
- the salt core could end run out wider than shown while increasing the cooling effect.
- the core 8 When the core 8 is removed from the cast part formed, it can accelerate the process Hot and possibly pressurized water.
- a first cylinder recess 15 of an engine block with a lining appears in FIG. 3 16, a first intermediate cylinder wall 17 and a lining 18 of the next Cylinder recess 19.
- An outer wall 20 of the engine block, a cylinder head surface 21, can also be seen Water jacket 22 and two stud bolts 23 for fastening a cylinder head.
- the mandrel forming the water jacket 22 24 shown is the mandrel forming the water jacket 22 24 shown. Molded into these is one with two thicker end sections 25 Graphite plate 26.
- the graphite plate has one between the thicker end portions 25 Thickness of about 1.2 mm and a height of about 12 mm. Stretches with these dimensions it is centered through the thickness of the intermediate cylinder wall 17, directly at a height under the stud bolts 23.
- the graphite plate 26 is finally removed by burning out. It will blow ignited by oxygen and burns out continuously if oxygen continues to flow into the is exposed by burning them out. This can accelerate happen from both sides. Deviating from this embodiment, the Graphite material may be mixed with an oxidizer that does not support such needless burnout enables.
- the water flow in the engine block is with a certain pressure drop between the one side of the row of cylinders and the other side. This is the through flows through the graphite plate 26 generated channel and thus a removal of heat enables.
- the method can also be used advantageously, in particular also for narrow water flow between the valve bores of a cylinder head.
- the reference number 27 in FIG. 5 and 6 denotes an engine block formed by casting.
- the soft hatching in the Motor block 27 shown in cross section consists of an aluminum alloy.
- With the reference symbol 28 is a mold part for forming a one surrounding the cylinders of the engine block 27 Designated cooling jacket.

- the glass core 31 has a diameter of 1 mm.
- a core is arranged between each of the cylinder recesses 32 of the engine block 27, as it emerges from FIGS. 5 and 6.
- the glass core 31 is cast around, the glass material having the resists the associated temperature load.
- a short time after pouring the glass core reaches the temperature of the casting material and thus its maximum thermal expansion during the casting process.
- the glass core now cools in the temperature weight together with the casting material, the casting material due to its higher coefficient of thermal expansion shrinks more than the glass core 31.
- This Shrinkage regularly causes the glass core 31 to shatter.
- the glass core can do this 31 be suitably pretreated by quenching, blasting, etching or / and scratching, in particular such that a large number of easily removable fragments are created.
- the glass core 31 is laid in the arc so that by the a flexible pushing tool through the openings formed towards the cylinder head contact surface can be introduced with the help in the event that the glass core during shrinkage is not or only partially broken, demolding takes place.
