Definitions
- the invention relates to a crankcase for a liquid-cooled reciprocating internal combustion engine, in which a cold room common to all cylinders is arranged and in which at least one flow-influencing element is provided is.
- the invention is based on the German patent application DE 36 32 160 A1.
- an internal combustion engine with a between the cylinder or cylinder liner and crankcase arranged cooling chamber, through which the Internal combustion engine coolant is conveyed, being in the cold room on the outside the turbulence plates pushed onto the cylinder or cylinder liner, flow-influencing elements are arranged.
- This Turbulence plates have turbulators that are pierced and bulged individual sections of the turbulence plate are formed. Through these turbulence sheets is the heat transfer from the cylinder or the cylinder liner to the Coolant increased.
- the object of the invention is to influence the coolant flow in a targeted manner to realize, in which the upper hot cylinder area is cooled more than that lower cold cylinder area.
- the system proposed in the invention is advantageously characterized by a differentiated flow of coolant through two sub-areas in the crankcase.
- the separation into a region with hot coolant and one with cold coolant is advantageously not defined by the plane of the cylinder head gasket.
- the flow-influencing element divides these areas in the area of the upper ring reversal of the piston rings in order to ensure optimal heat dissipation.
- the temperature in the cold rooms is set automatically by the current operating point of the internal combustion engine due to the temperature and pressure conditions and the size of the openings in the flow-influencing elements.
- the need-based cooling achieves an advantage in the service life, in consumption and in the emissions of the internal combustion engine.
- the flow influencing by the flow influencing is advantageous according to claim 2 Element even more controllable and a clamp assembly is through this geometry is easily possible.
- Claim 3 again supports the advantages of Claim 2.
- An embodiment according to claim 4 ensures freedom from maintenance during operation. Furthermore can be different with the different materials Generate advantageous component properties such. B. the realization of hard or elastic sub-areas.
- An embodiment according to claim 6 allows simple assembly, for example as a pinching or plug-in solution.
- a device according to claim 7 helps the flow-influencing element Places subject to high mechanical loads to prevent slipping due to flow resistance to secure.
- a manufacture according to claim 8 offers simple and inexpensive manufacture as well as an inexpensive and simple assembly.
- the invention is based on two preferred exemplary embodiments shown in a drawing.
- Figure 1 shows a section through an open-deck crankcase 1, the centric runs through a cylinder 2 with a cylinder axis 2a. On both sides of the cylinder, Equidistant from the cylinder axis 2a, two cooling rooms 3, 3 'are in the Crankcase 1 arranged.
- Open deck crankcase means the cold rooms 3, 3 'in the crankcase 1 compared to a cylinder head, not shown only closed by a cylinder head gasket 8 with coolant passage openings 9, 9 ' are.
- the cylinder 2 On the opposite side of the cylinder head gasket the cylinder 2 in a crank chamber 10 of a reciprocating piston internal combustion engine, not shown.
- Flow-influencing elements 4, 4 ' are located in the cooling rooms 3, 3' Openings 5, 5 '.
- At the flow-influencing element 4 are three ribs 6, 6 ' formed.
- the flow-influencing elements 4, 4 ' have partial areas a surface curvature 7, 7 '.
- the coolant passage openings 9, 9 'in the cylinder head gasket 8 are arranged in the area of the cooling rooms 3, 3'.
- the flow-influencing elements 4, 4 ' divide the cold rooms 3, 3' into upper ones Cold rooms 3a, 3'a and in lower cold rooms 3b, 3'b.
- a pump delivers Coolant pump the coolant through an opening, not shown, into the upper one Coolant rooms 3a, 3'a.
- the current operating conditions e.g. the load conditions of the reciprocating internal combustion engine
- the load conditions of the reciprocating internal combustion engine is due to the prevailing Temperature and pressure conditions in the cold rooms 3, 3 'that Coolant through the openings 5, 5 'and the coolant passage openings 9, 9' from the upper coolant spaces 3a, 3'a into the lower coolant spaces 3b, 3'b and distributed in the cylinder head, not shown.
- the coolant can at least in Partial areas also from the cylinder head through the coolant passage openings 9, 9 ' into the upper cold rooms 3a, 3'a and from there into the lower cold rooms 3b, 3'b are pressed.
- one Element 4 ' is about 80% of the crankcase from the combustion chamber emitted amount of heat entered.
- the openings 5, 5 'and the coolant passage openings 9, 9 ' are dimensioned such that there are in the lower cold rooms 3b, 3'b only a very weak flow and in the upper cold rooms 3a, 3'a a high flow velocity in the direction of the not shown Cylinder head adjusts.
- the flow-influencing element 4 is shaped such that the ribs 6, 6 'additionally act as holding elements during assembly. They also take over also the task of directing the coolant around the cylinder 2. For additional Clamping the flow-influencing element 4 are surface curvatures 7, 7 'available. The areas of the surface curvature are elastic, can also be designed stiff.
- Portions of the flow-influencing element 4 ' are on the cylinder side and crossed on the crankcase side, which also causes surface curvatures 7 'can be achieved. Here, too, they serve as an assembly aid during installation into the cooling space 3 ', the resilient effect of the surface curvature 7' is used to the flow-influencing element 4 'between the crankcase wall and to wedge the cylinder wall.
- the cooling system both as a cooling system with a coolant circuit and as a split cooling system be carried out.
- Split cooling system means the use of two separate coolant circuits for a reciprocating piston internal combustion engine. On Cooling circuit cools the crankcase 1, the coolant flow in turn the upper cold rooms 3a, 3'a and the lower cold rooms 3b, 3'b is divided and the coolant is also discharged again from the upper cold rooms 3a, 3'a. Another cooling circuit cools the cylinder head, not shown. At a Split cooling system is used to regulate the coolant temperature in each Flow area through two separate controllers.

Abstract
Description
Die Temperatur in den Kühlräumen stellt sich selbstständig durch den aktuellen Betriebspunkt der Brennkraftmaschine aufgrund der Temperatur- und Druckverhältnisse sowie der Größe der Öffnungen in den strömungsbeeinflussenden Elementen ein. Durch die bedarfsgerechte Kühlung wird ein Vorteil in der Lebensdauer, im Verbrauch und in den Emissionen der Brennkraftmaschine erzielt.
