Definitions
- the invention relates to a cylinder block for a water-cooled internal combustion engine with at least one cylinder surrounded by a cooling jacket, with a connection surface for a cylinder head, which has at least one transfer opening for coolant from the cooling jacket into the cylinder head.
- the object of the invention is to influence both the flow of the coolant between the cylinder block and the cylinder head and the flow within the cylinder block in the simplest possible way.
- a flow limiter is inserted into the transfer opening, the flow limiter preferably being arranged at least partially within the cooling jacket.
- the flow limiter is formed by a tube, the outer diameter of the flow limiter preferably corresponding essentially to the diameter of the transfer opening.
- the longitudinal axis of the flow limiter is advantageously arranged approximately parallel to the cylinder axis.
- the flow restrictor can be made of metal or plastic.
- the flow cross-section within the cooling jacket is reduced and the coolant flow around the cylinder is thus influenced in a targeted manner.
- the length of the flow limiter essentially corresponds to the height of the cooling jacket and the flow limiter preferably extends over the entire height of the cooling jacket. It is particularly advantageous if the essentially cylindrical flow restrictor has at least one inlet opening in the area of its lateral surface, the inlet opening being preferably arranged in the cooling jacket on a side facing away from the coolant flow. The coolant flows from the cooling jacket into the inlet opening into the interior of the flow limiter and via the outlet opening on the cylinder head into the cooling chamber of the cylinder head.
- the flow in the cooling jacket of the cylinder block and in the cooling chamber of the cylinder head can be influenced in a targeted manner by dimensioning the inlet opening, the inner cross section of the tube, by selecting the position of the inlet opening and the distance between the flow limiter and the inner wall of the cooling jacket.
- the flow limiter has a drain opening in the region of its end face facing the crank chamber. This ensures that the cooling system is completely drained.
- FIG. 1 shows a cylinder block according to the invention with a flow limiter in a section along the line II in FIG. 2
- FIG. 2 shows this cylinder block in a section along the line II-II in FIG. 1
- FIG. 3 shows the detail III from FIG. 1
- 4 shows the detail IV from FIG. 2
- FIG. 5 shows a flow limiter in an oblique view.
- the cylinder block 1 of an internal combustion engine shown in Figures 1 to 4 has a plurality of cylinders 2 for pistons not shown.
- the cylinder block 1 can be formed separately or in one piece with the crankcase.
- a cooling jacket 3 is arranged around the cylinders 2.
- the cooling jacket 3 is connected to the cooling chambers of this cylinder head via transfer openings 4 in a connection surface 5 for a cylinder head (not shown).
- a flow limiter 6 is inserted into the transfer openings 4 of at least one outer cylinder 2 of the cylinder bank.
- the flow limiter 6 is essentially formed by a tube 7 with open end faces 8, 9, the outer surface 10 of the tube 7 having an inlet opening 11 in the cylinder head-side third.
- the outlet opening on the end face 9 facing the cylinder head is designated by reference numeral 12.
- the longitudinal axis 6a of the flow limiter 6 runs somewhat parallel to the cylinder axis 2a.
- the length h of the tube 7 is dimensioned such that the flow limiter 6 extends essentially over the entire height of the cooling jacket 3.
- the tube 7 In the area of the end face 8 facing the crank chamber 13, the tube 7 has a drain opening 14 in order to allow the coolant to flow freely from the tube 7 when the coolant is emptied.
- a bead 15 formed by the casting process of the cooling jacket 2 in the region of the bottom of the cooling jacket 3 supports the drainage from the pipe 7.
- the tube 7 is pressed into the transition opening 4 of the cylinder block 1.
- the tube 7 has a collar portion 16 with a greater wall thickness s in the area of the transition opening 4 for the press fit than in the other areas.
- the tube 7 can consist of metal, for example aluminum or steel, or also of temperature-resistant plastic. Instead of a press connection.
- the flow limiter 6 is inserted into the transition opening 4 in such a way that the inlet opening 11 is located on the side of the cooling jacket 3 facing away from the flow.
- the flow is indicated by arrows P in FIG. 4.
- the flow cross-section of the cooling jacket 3 is significantly reduced by the tube 7 inserted in the cooling jacket 3 and the flow in the cooling jacket 3 is thereby influenced in a targeted manner and redirected into other areas of the cooling jacket 3, which also means the inner cylinders 2 of the cylinder bank are cooled sufficiently.
