Definitions
- the invention relates to a cylinder housing of an internal combustion engine having at least two juxtaposed cylinders, each with a wet cylinder liner, which is received by a support structure, wherein between the support structure and the cylinder liner, a coolant jacket is arranged, with a cylinder head sealing surface forming a closed deck being in the region of a motor transverse plane at least one screw receptacle for a cylinder head screw is arranged between two cylinders.
- a cast cylinder housing with a wet cylinder liner is known for example from DE 10 2012 111 521 AI.
- the cylinder liners receiving support structures of the cylinder housing of two adjacent cylinders in the engine transverse plane are interconnected. This results in mechanical and thermal disadvantages.
- a cast cylinder housing which has relatively deep arranged in the cylinder housing screw receptacles for the cylinder head bolts.
- the screw receptacles are positioned in a central region of the cylinder and spaced from the upper deck.
- the object of the invention is to propose a cylinder housing, which allows optimal cooling and reduces the mechanical stress of the cylinder housing.
- this object is achieved in a cylinder housing of the type mentioned above in that the support structures of two adjacent cylinders in the intersection region of the engine transverse plane with one of the cylinder axes-containing engine longitudinal plane are exempted from each other. This reduces deformation of the cylinder liner.
- the invention results in an advantageous distribution of force in a one-piece, for example cast, cylinder housing.
- a main bearing wall formed integrally with the cylinder housing is arranged in the region of at least one engine transverse plane between two cylinders.
- the minimum distance between two adjacent support structures in the area of the coolant jacket corresponds to at least half the cylinder head screw diameter, preferably at least the cylinder head screw diameter. This allows a substantial thermal and mechanical decoupling of two adjacent cylinders from each other.
- At least one screw receptacle is spaced from the deck. At least one screw receptacle is arranged in a variant of the invention in a central region of the cylinder, wherein preferably the screw receptacle laterally adjacent to two adjacent support structures. This allows a substantial decoupling of the cylinder head bolts from the support structure.
- the support structure is formed in the region of the coolant jacket substantially hollow cylindrical, with a particularly good cooling of thermally highly stressed areas can be achieved when the coolant jacket between a cylindrical inner wall of the support structure and a cylindrical outer wall of the cylinder liner, preferably in the upper third of the cylinder formed is.
- the support structure has a conically shaped transition region in a region adjoining the coolant jacket in the direction of the crank chamber, preferably in the region of the screw receptacle, wherein the conically shaped transition region tapers in the direction of the deck. It is particularly advantageous if at least two adjacent support structures in the region of the base of the conically shaped transition regions are connected to one another via an intermediate deck. Preferably, the intermediate deck is connected to a main bearing wall. This causes an advantageous introduction of force from the first screw receptacle in the main bearing wall and a stable mechanical support of the cylinder housing.
- the support structure is subjected to tensile forces in a region formed between the cylinder head sealing surface and the screw receptacle by compressive forces and the remaining region of the support structure and the main bearing walls.
- This allows a substantial mechanical and thermal decoupling on the one hand the cylinder from each other and on the other hand from the cylinder head bolts.
- a deformation of the cylinder liner is reduced.
- FIG. 1 shows a cylinder housing according to the invention in a section along the line I-I in Fig. 2.
- FIG. 2 shows the cylinder housing in an oblique view in a section along the line II-II in Fig. 1st
- the cylinder housing 1 of an internal combustion engine is designed for a plurality of juxtaposed cylinders 2 with wet cylinder liner 3, which are each received by a support structure 4 of the cylinder housing 1.
- the cylinder housing 1 is made in one piece and takes over both the function of supporting the cylinder liners 3, as well as a crankshaft, not shown.
- the cylinder housing 1 has integrated main bearing walls 18 in the region of engine transverse planes 8.
- the main bearing walls 18 can be formed exactly in the respective engine transverse plane 8 or slightly offset from this.
- a housing skirting of the cylinder housing 1, for example, integrated in one casting process or an additive process, for example an SD printing process biases a crank chamber 16 for accommodating the crankshaft.
- crankcase 1 made in one piece crankcase including crankcase skirt and main bearing walls 18 of the engine.
- a coolant jacket 5 is arranged between the support structure 4 and the cylinder liner 3, a coolant jacket 5 is arranged. On both sides of the coolant jacket 5, the cylinder liner 3 is located on sealing surfaces 4a, 4b of the support structure 4 close to this, with reference numeral 11 seals are designated.
- the support structures 4 are formed in the region of the coolant jacket 5 is substantially hollow cylindrical.
- the coolant jacket 5 fed by the coolant channel 20 via the transfer channel 21 extends in the radial direction between a cylindrical inner wall 13 of the support structure 4 and a cylindrical outer wall 14 of the cylinder liner 3 and is arranged in the upper third 15 of the cylinder 2.
- the upper third 15 is to be understood here as the third of the cylinder 2 which faces the cylinder head sealing surface 6.
- the transfer channel 21 opens in an arc in the coolant jacket 5, whereby the amount of coolant is divided over the cylindrical coolant jacket 5 in a predefined manner. This allows a uniform cooling of the cylinder 2.
- this has a closed deck 7 forming a cylinder head sealing surface 6.
- a motor transverse plane 8 are between two cylinders 2 two screw receptacles 9 for a not shown Zylinderkopfsch spaced from the deck 7.
- the distance b of the screw receptacle 9 from the deck 7 corresponds approximately to half the cylinder diameter D of the cylinder 2.
- the screw receptacles 9 can be formed exactly in the respective motor transverse plane 8 or slightly offset from this.
- the support structures 4 of two adjacent cylinders 2 are separated from one another in the sectional area S of the engine transverse plane 8 with an engine longitudinal plane 10 containing the cylinder axes 2a, wherein the minimum distance a of two adjacent support structures 4 in the region of the coolant jacket 5 in the exemplary embodiment corresponds approximately to the cylinder head screw diameter d.
- the screw receptacles 9 are located in a middle third 12 of the cylinder 2. Each screw receptacle 9 adjoins the side of two adjacent support structures 4.
- the support structures 4 have in the coolant jacket 5 in the direction of the crank chamber 16 subsequent areas - especially in the screw receptacles 9, conically shaped transition regions 17.
- the conically shaped transition regions 17 taper in the direction of the deck 7.
- adjacent support structures 4 are connected to one another via an intermediate deck 19.
- This arrangement forms an advantageous force guide with compressive forces C and tensile forces T in the cylinder housing 1, as indicated in Fig. 2.
