Definitions
- the invention relates to a crankcase for an internal combustion engine with the features of the preamble of patent claim 1.
- a cylinder crankcase is known, in particular for an internal combustion engine, with at least one cylinder bore for receiving a piston. It is provided that the cylinder bore on the cylinder head surface, or the separating surface, of the cylinder crankcase has an inlet chamfer and the cylinder surface to a transition to the run-in phase with a thermal
- the countersink can preferably be implemented simultaneously with the introduction of the chamfer.
- the production according to claim 4 is particularly preferred. This may be, for example, grinding, milling, etc.
- Claim 5 manufactured in a single operation.
- Fig. 1 shows the top view of a three-dimensional cut
- FIG. 2 shows a detail enlargement of the cylinder bore of Fig. 1 in a two-dimensional sectional view.
- Fig. 1 shows the top view of a three-dimensional cut shown inventive crankcase 1.
- crankcase 1 is a crankcase 1 with three recognizable coated cylinder bores 2, wherein the inventive
- crankcase 1 has a separating surface 3 to a cylinder head, not shown.
- a transition from the cylinder bore 2 is chamfered to the separation surface 3, for better insertion of a piston, not shown (Kolbeneinwovenfase).
- a countersink 5 is arranged on the chamfer 4.
- crankcase 1 is a
- Light metal crankcase preferably of a hypoeutectic
- the cylinder bore 2 is coated, whereby it has on its surface a greater hardness for improved tribology with a piston ring than the remaining material of the crankcase first
- FIG. 2 shows an enlarged detail of the cylinder bore 2 from FIG. 1 in a two-dimensional sectional illustration.
- 2 is a construction drawing of the chamfer 4 according to the invention with countersink 5.
- the crankcase 1 is shown hatched and the chamfer 4 is arranged in this embodiment in the cylinder bore 2 only in a coating 6.
- the chamfer 4 can also extend into the carrier material (here AISi9Cu3).
- the chamfer 4 to the cylinder bore 2 at an angle a between 5 ° and 60 °.
- the Countersink 5 a depth of at least 0.05 mm and at least 0.1 mm larger diameter than the chamfer 4 on.
- the chamfer 4 and the countersink 5 machined off, such as by a grinding or milling process, etc.
- the chamfer 4 and the countersink 5 are made in a single operation.
