Definitions
- the invention relates to an internal combustion engine with at least one cylinder bank in series arranged in at least one cylinder block and with at least one fluid cooling system associated with each cylinder bank with at least one in the cylinder block trained fluid channel, which fluid through the cylinder block adjacent as a water jacket leads to the cylinders for their cooling, the fluid channel in between a cylinder head and a crankcase arranged cylinder block on the crankcase side from a floor is delimited, according to the preamble of claim 1.
- US Pat. No. 4,455,972 describes a cylinder block with a water tank, one of which is in the direction of flow extending the water tank into an upper and an lower section divides: The dividing wall is seen in the flow direction formed obliquely that the upper section narrows, whereas the lower section Section widened.
- this arrangement is complicated and leads to the additional one Wall to turbulent flows, which remove heat energy through the Hinder cooling water.
- a cooling system for a reciprocating piston internal combustion engine is known from EP 0 671 552 B1, an upper subchannel system assigned to the combustion chambers of the cylinders into one Cylinder head is open and with a uniform coolant spaces in the cylinder head forms the upper channel system, the coolant spaces located in the cylinder head from Sub-channel system in the cylinder block by several distributed over a cylinder head base plate Passages are supplied with coolant.
- this also results in considerable Disadvantages due to additional turbulence, especially on the passages on the Cylinder head base plate.
- EP 0 752 524 A1 discloses a cooling water jacket in a cylinder block for cylinders an internal combustion engine, with a flow width perpendicular to the flow direction the coolant towards a crankcase closing the cylinder block, i.e. of top down, gradually narrowing.
- these stages lead to undesirable ones Turbulence in the water flow and accordingly hinder the cooling function of the flowing Water.
- EP 0 196 635 A2 describes an internal combustion engine with at least two in a row lying liquid-cooled cylinders, with a flow cross-section of a cold room between the cylinder block wall and the cylinder wall on one side of a respective cylinder is larger than on a correspondingly opposite side.
- Wide and narrow sections alternate from cylinder to cylinder.
- this has the Disadvantage that there are corresponding transition points between wide and narrow Sections form turbulence in the coolant flow, which is effective Limit the removal of thermal energy through the cooling water accordingly.
- Cooling water cavities in the cylinder block correspond to cylinders formed in the cylinder block surround.
- a lower area of the cooling water cavities is heat-resistant plastic material partially filled.
- the cylinder block is on different requirements with regard to the cooling conditions subsequently customizable, but this is complex and costly.
- the cylinder block is on different requirements with regard to the cooling conditions subsequently customizable, but this is complex and costly.
- the padded one Cooling water cavity only corresponding to one already in the manufacture of the Cylinder block made smaller cavity. Special fluidic conditions Regarding turbulent flows separating from the bottom of the cooling water cavities especially when the cooling water flow rate is high considered.
- DE 24 17 925 C2 discloses a liquid-cooled multi-cylinder internal combustion engine, an additional one separated from a water jacket surrounding the cylinders Coolant chamber is provided, which narrows horizontally in the direction of flow and flows into the water jacket downstream.
- this is particularly true in the area of Junction to turbulent flow through different flow velocities and vectors of the confluent currents.
- this turbulence hampers you Heat dissipation through the cooling medium.
- DE-OS 2 058 094 describes a liquid-cooled multi-cylinder Internal combustion engine with a cooling water channel that enters a cooling water chamber Crankcase is cast, is open towards a cylinder head and its Cross section decreases steadily starting from a supply point for cooling water. This too The arrangement does not take into account that in particular the bottom of the cooling water cavities replace turbulent flows when the cooling water flows at high speed.
- the present invention is therefore based on the object of an internal combustion engine to provide the above type, overcoming the above disadvantages and an optimized laminar flow of the cooling fluid over an entire length of a Cooling channel is achieved in the cylinder block.
- the bottom of the fluid channel in the form of a curved plane is formed.
- the curved plane is expediently designed such that in the direction of flow of the fluid in the fluid channel with several successive increases accordingly depressions in between are formed, preferably the elevations and depressions follow each other cyclically.
- a cylinder tube warp during operation of the internal combustion engine is easier to control, since the water tank formed by the fluid channel is less in the area of the cylinders Has expansion.
- a particularly good laminar flow over the entire length of the fluid channel in the Cylinder block is achieved by making the plane a continuously differentiable cross-section Curve is.
- a particularly low-turbulence guidance of the fluid flow in the fluid channel is achieved by that the plane in cross section is a sine curve or cosine curve.
- a more homogeneous flow with largely avoiding turbulence in the Coordination of fluid flows from fluid channels arranged on both sides of the cylinder is achieved in that the bottom at a downstream end of the fluid channel at the the fluid channels on both sides reunite, one in the direction of the cylinder head has a predetermined length-extending elevation, which the respective fluid flows of the two-sided channels in before they converge upwards towards the cylinder head distracting.
- the fluid channel is on the cylinder head side of a ceiling closed (open deck) or open, the latter variant advantageously a fluid-conducting connection with a fluid system in the cylinder head in sogn. "open deck” construction realized.
- a particularly good cooling and heat energy dissipation is achieved in that the fluid Is water.
- FIG. 10 This schematically shows a preferred embodiment of a fluid channel 10 .mu.m Cylinder 12 of an internal combustion engine which is otherwise not shown in detail Water box through which in the direction of arrow 14 a cooling fluid, such as Cooling water flows.
- a cooling fluid such as Cooling water flows.
- the fluid flows around the cylinders 12 and cools them by removing the fluid from heat energy is removed from the cylinder walls.
- the water tank or the fluid channel 10 is delimited by a bottom 16 in the figure below.
- the bottom 16 is designed as a curved surface, the surface in a cross section along the flow direction 14, a sinusoidal curve is undulating. It is however, according to the invention, any other curvature with one another cyclically or non-cyclically following mountains and valleys. Seen in the direction of flow follow in this exemplary embodiment on the bottom 16 wave crests 18 and wave troughs 20 alternately each other. In the region of the bottom 16, the flow of the fluid follows this sine curve, with the formation of turbulence even at high flow velocities by a such guidance of the flow on the ground is largely avoided. Furthermore, improved one such forced flow a distribution and mixing of the fluid in the water tank, so that better cooling with less fluid is possible.
- the curved surface of the bottom 16 is designed, for example, such that in essentially form 12 wave crests 18 in the cylinders. This achieves a better one Manageability of a tube distortion of the cylinder 12 during the operation of the Internal combustion engine by a corresponding to the distribution of thermal energy to the Flushing geometry of the fluid around the cylinders 12 configured for cylinder walls.
- turbulent flow in this area is additionally an increase 24 provided which extends from the floor 16 towards the cylinder head.
- This increase 24 is designed such that it directs the mutual flows of the fluid Deflects cylinder head in the Fig. So that at a downstream end 26 of Increase 24 the two partial flows flow into each other without any special eddies.
- the Elevation 24 extends over a predetermined length in the direction of the cylinder head (in the Fig. In the upward direction). In a preferred embodiment, the elevation 24 rises over an entire height of the water tank to a parting plane between the cylinder block and Cylinder head.
- the vortex-free or turbulence-free mixing occurs at the upper end 26 of the elevation 24 in that by diverting the partial flows on both sides in have substantially rectified flow vectors. Furthermore realized the increase a targeted water supply to the cylinder head.
