Definitions

  • the invention relates to a cylinder block of the closed-deck type, containing one cast cylinder block core with at least one cylinder and a water jacket.
  • the invention further relates to a method for producing such Cylinder block.
  • From DE 28 36 810 A1 is a cylinder block made in light metal die casting known from the so-called closed-deck type.
  • the cylinder block has several Cylinder for receiving the piston of an internal combustion engine, the cylinder are surrounded by a water jacket for cooling.
  • the execution of the Cylinder blocks in the closed-deck form state that the water jacket is facing up is closed - except for possible smaller openings.
  • the water jackets for cylinder blocks extend from open-deck type up to the top of the cylinder block, so that this from later mounted cylinder head must also be covered and sealed. This Sealing is usually very prone to failure and expensive.
  • cylinder blocks have of the open-deck type a structurally lower stability and Stiffness.
  • Theoretically is from DE 28 36 810 A1 also a die-cast process Embodiment of a cylinder block of the closed-deck type known, at which the water jacket is open on the underside towards the crankcase.
  • an object of the present invention was an option that can be used in practice for producing a cylinder block of the closed-deck type in the die casting process.
  • the closed-deck type cylinder block of the present invention includes a cast one Cylinder block core with at least one cylinder and with a water jacket.
  • the cylinder block is characterized in that the cylinder block core does not surround the water jacket on the outside facing away from the cylinder.
  • the water jacket is therefore not on it Narrow side up (open deck) or down (DE 28 36 810 A1) open, but this is more or less completely open to the outside.
  • This allows the cylinder block core to be manufactured in a die casting process which enables cost-effective mass production of the cylinder block becomes.
  • the cylinder block has the advantages of the closed-deck type, So a simpler and better sealing of the cylinder by the cylinder head as well as greater rigidity of the cylinder block.
  • the one facing away from the cylinder Side can additionally or alternatively also by reinforcing ribs be designed so that by the combustion pressure and / or by screw forces occurring cylinder deformations are reduced.
  • the cylinder block preferably has one connected to the cylinder block core Cover on which the water jacket on the side facing away from the cylinder closes.
  • the cover consists of one Material consists of good heat conduction properties with high stability having.
  • the cover can be a water jacket be shaped or profiled in such a way that the flow and / or the heat distribution in the water jacket is optimized.
  • the cover By being a relative large side wall surface of the water jacket through the separate cover is formed, it is possible to give this surface an optimal shape, without the manufacturing limitations of a cast manufacturing process to be subject.
  • the water jacket of the cylinder block preferably extends over the top approx. 20 to 50% of the height of the cylinder. This is the main area of focus the heat of combustion, so that good cooling is important here.
  • the cylinder block core comprises in one piece also a crankcase, which surrounds the crankshaft.
  • the cylinder block core advantageously consists of a light metal, which can be aluminum in particular.
  • the invention further relates to a method for producing a cylinder block of the type explained above, which is characterized in that the cylinder block core is produced in a die casting process. Furthermore, the side open water jacket through corresponding projections in the die casting mold trained, or this is from the completion of the die casting process the castings obtained.
  • Advantageous in this manufacturing process is the use of a die casting process, which is an inexpensive mass production allowed.
  • a cylinder block core is used side cover of the water jacket connected. This connection can in particular done by screwing. Because the water jacket on its open side is closed by its own cover and not how in the case of open-deck forms that have to be closed by the cylinder head, the Design of the corresponding interfaces optimal in relation to the (smaller) Requirements of a water jacket seal are made.
  • the figures show a one-piece cylinder block core 1 of a four-cylinder in-line engine.
  • the cylinder block core 1 has four in contact with each other ("Siamese") cylinder 2, at the lower end of which a crankcase 4 is attached is.
  • Siamese cylinder 2
  • On the outward-facing side surfaces of the cylinder is a cavity a water jacket 3 is formed, the top 7 of which is shot.
  • at the cylinder block core 1 is therefore one of the closed deck Type, which by a higher stability and less problems with the sealing is characterized by the cylinder head (not shown).
  • the water jacket 3 is open to the side of the cylinder block core 1 educated. This makes it possible to die-cast the cylinder block core 1 to manufacture and at the same time to realize the closed-deck shape.
  • the Formation of the cavities of the water jacket 3 can be done by appropriate Protrusions are made in the die. Alternatively, the water jacket can be removed Completion of the die casting milled into the cylinder block core from the side become.
  • boreholes 8 with an internal thread are provided on the side in the cylinder block core, over each of which a cover 9 (only one is shown in FIGS. 2 and 3) made of sheet metal or another suitable material onto the water coats can be screwed on.
  • This cover 9 is preferably on their inside shaped and designed so that these the water flow and optimizes the heat distribution.
  • the sectional view of Figure 2 also shows the between two cylinders 2 located chambers 6 of the water jacket and the screw holes 5 running parallel to the cylinders 2 for the cylinder head.
