Definitions

  • the invention relates to an internal combustion engine with at least one cylinder bank of in series in at least a cylinder block arranged cylinders and at least one of a respective cylinder bank associated fluid cooling system with at least one formed in the cylinder block fluid channel, which Fluid adjacent to the cylinder block as a water jacket leads to the cylinders for their cooling, wherein the fluid channel in between a cylinder head and a crankcase arranged cylinder block crankcase side is delimited from a soil, according to the preamble of claim 1.
  • U.S. Patent 4,455,972 describes a cylinder block with a water box, one in the Flow direction extending wall the water box in an upper and a lower section divides: In the flow direction is the dividing Wall formed inclined so that the upper section narrows, whereas the lower section narrows Widened section. This arrangement is however complicated and leads through the additional wall turbulent flows, which a removal of Hinder heat energy through the cooling water.
  • EP 0 752 524 A1 discloses a cooling water jacket in a cylinder block for cylinder one Internal combustion engine, which has a flow width perpendicular to the flow direction of the coolant in Direction of a cylinder block final crankcase, i.e. from top to bottom, narrowed in steps. However, these steps lead to unwanted Turbulence in the water flow and hinder accordingly the cooling function of the flowing water.
  • EP 0 196 635 A2 describes an internal combustion engine with at least two consecutive liquid cooled cylinders, wherein a flow cross section a cold room between cylinder block wall and cylinder wall on one side a respective cylinder is greater than on a corresponding opposite side.
  • a flow cross section a cold room between cylinder block wall and cylinder wall on one side a respective cylinder is greater than on a corresponding opposite side.
  • this has the disadvantage that at appropriate crossing points between wide and narrow sections turbulence form in the cooling liquid flow, which is a effective dissipation of heat energy by the cooling water restrict accordingly.
  • DE 24 17 925 C2 discloses a liquid-cooled Multi-cylinder internal combustion engine, wherein separated by a water jacket surrounding the cylinder provided an additional coolant chamber is which is horizontal in the flow direction narrowed and flows downstream in the water jacket.
  • an additional coolant chamber is which is horizontal in the flow direction narrowed and flows downstream in the water jacket.
  • DE-OS 2 058 094 describes a liquid-cooled multi-cylinder internal combustion engine with a cooling water channel that enters a cooling water space a crankcase is poured in the direction of a cylinder head is open and whose cross section starting from a feed point for cooling water steadily decreasing. Also this arrangement considered not that at the bottom of the cooling water cavities especially at high flow velocity of Cooling water to replace turbulent flows.
  • DE 41 40 772 A1 discloses a device for cooling webs between cylinders of a cylinder block an internal combustion engine known. These Webs are between at least in the area of a cylinder block an internal combustion engine Cylinders arranged and have cooling channels on. Especially when entering and leaving the flow in the Cooling channels of the webs in or out of these However, it comes to turbulent flow, which the Cooling function of the coolant impaired.
  • the present invention is therefore the Task is based, an internal combustion engine of the above Art to provide, the above Disadvantages are overcome and an optimized laminar flow of the cooling fluid over an entire Length of a cooling channel achieved in the cylinder block becomes.
  • the bottom of the fluid channel in the form of a curved Level is formed.
  • the curved plane designed such that in the flow direction of the Fluids in the fluid channel several consecutive increases with corresponding intervening Lowered are formed, wherein preferably the elevations and sinks follow each other cyclically.
  • a cylinder tube delay during operation the internal combustion engine is better manageable, since the formed by the fluid channel water tank in the area the cylinder has a smaller extension.
  • a particularly low-turbulence leadership of Fluid flow in the fluid channel is achieved in that the plane in cross section a sine curve or cosine curve is.
  • a more homogeneous flow with more extensive Avoidance of turbulence at the meeting arranged by fluid flows from both sides of the cylinder Fluid channels are achieved by the fact that the soil at a downstream end of the fluid channel which the mutual fluid channels reunite, one in the direction of the cylinder head by a predetermined Has length-extending survey, which the respective fluid flows of the mutual channels in front of their confluence upwards in the direction Deflects cylinder head.
  • the Fluid channel on the cylinder head side closed by a ceiling (closed deck) or open advantageously a fluid-conducting connection with a fluid system in the cylinder head in Sogn. realized "open deck” construction.
  • FIG. 12 This shows schematically a preferred embodiment a fluid channel 10 around cylinder 12th an otherwise not shown internal combustion engine forming water box, by the arrow in the direction 14 a cooling fluid, such as Cooling water, flows.
  • a cooling fluid such as Cooling water
  • the fluid flows around the cylinder 12th and cools this by removing the fluid from the cylinder walls Heat energy removed.
  • the water tank or the fluid channel 10 is limited in the bottom of a bottom 16.
  • the floor 16 is formed as a curved surface, wherein the Surface in a cross-section along the flow direction Fig. 14 shows a sine wave waveform runs.
  • wave peaks 18 and wave troughs 20 alternately on each other.
  • the area of Soil 16 thus follows the flow of the fluid of this Sinusoid, whereby a formation of turbulence also at high flow velocities through such Maintaining the flow on the ground largely is avoided. Further, such a forced one improves Flow a distribution and mixing of the Fluids in the water tank, allowing better cooling with less fluid is possible.
  • the curved surface of the bottom 16 is here exemplified such that substantially form 12 peaks 18 at the cylinders. This achieves a better controllability of a pipe distortion the cylinder 12 during operation of the Internal combustion engine by one according to the distribution the heat energy at the cylinder walls designed Um Togethergeometrie the fluid around the cylinder 12 around.
  • an increase 24th provided, which extends from the bottom 16 in the direction of the cylinder head extends.
  • This elevation 24 is designed such that that they are the mutual currents of the Fluid in the direction of the cylinder head in the Fig. Upwards deflects so that at a downstream end 26 of the Increase 24 the two partial flows without special Turbulences flow into each other.
  • the increase 24 extends over a predetermined length in Direction of the cylinder head (in the direction towards above). In a preferred embodiment, elevates the elevation 24 over an entire height of the water box up to a parting line between cylinder block and cylinder head.
