Definitions

  • the invention relates to a cooling system for a liquid-cooled reciprocating piston internal combustion engine, the cylinder block and cylinder head of which coolant flows, which is conveyed by a pump and, after passing through the internal combustion engine, is guided in a closed circuit to a cooler, an upper one assigned to the combustion chambers of the cylinders in the cylinder block Channel system and a separate lower channel system adjacent to the crank mechanism are formed.
  • Such a cooling system is described in DE 32 26 880 A1.
  • this known cooling system there is another channel system located in the cylinder head above the upper channel system arranged in the cylinder block, which channel system is supplied with relatively cool coolant via a thermostatic valve via the lower channel system located in the cylinder block.
  • a thermostatic valve via the lower channel system located in the cylinder block.
  • the object of the invention is to provide a cooling system of the type mentioned, in which, while maintaining the advantages of such a system, a balanced temperature level also occurs around the combustion chambers, so that thermal stresses in this area can be largely avoided and that a targeted flow heat-sensitive areas in the vicinity of the cylinder head base plate is possible.
  • both the cylinder block and the cylinder head, including the cylinder block have a uniform temperature in the area of the combustion chambers of the internal combustion engine, so that undesired thermal stresses can be controlled.
  • several are distributed over the entire contact area between the cylinder block Passages and cylinder head arranged a targeted flow to the heat-sensitive areas, especially in the vicinity of the cylinder head base plate possible.
  • the portion of the cooling liquid located in the lower channel system ie close to the crank mechanism, absorbs a significantly smaller amount of heat than the upper channel system, namely the amount emitted via the cylinder walls; again the greater proportion of heat is present in the lower turning point of the reciprocating piston due to the length of time the reciprocating piston stays, so that this area is preferably particularly encompassed by the lower channel system.
  • the coolant should warm up quickly. This is done for the amount in the upper duct system, compared to the total amount by the proportion of the quantity in the lower duct system, in that the cooler is short-circuited in a manner known per se by a main thermostatic valve and a short-circuit line and the amount of heat arising around the combustion chambers is almost completely in the circulating Coolant remains.
  • the heat exchanger for heating is also in this circuit. Sufficiently heated coolant is therefore available for heating purposes very quickly after the engine is started.
  • the cooler is not included in the circuit until the operating temperature of the internal combustion engine has been reached, so that excess heat is then dissipated via the cooler.
  • the coolant located in the lower channel system is only included in the coolant circuit when the thermostatic valve at the outlet of this channel system opens, which happens when a temperature is reached that approximately corresponds to the operating temperature of the internal combustion engine, but is slightly below this.
  • the desired operating temperature is quickly reached there, despite the less heat being generated there.
  • An internal combustion engine 1 has a cylinder block 2 and a cylinder head 3.
  • the cylinder block 2 contains, next to the crank mechanism 4 located in it, a channel system 5 which is delimited at the top by a partition 6 which lies in a plane just below piston rings 7 of the reciprocating piston 8 located in the top dead center of the internal combustion engine 1.
  • Above the partition 6 there is still a sub-channel system 9 within the cylinder block 2, which forms an upper channel system 12 connected to a sub-channel system 10 in the cylinder head 3 via a plurality of passages 11 distributed over the cylinder head base plate.
  • This upper channel system 12 thus extends around the areas near the combustion chamber of both the cylinder head 3 and the cylinder block 2. It is connected to the lower channel system 5 located below the partition 6 only by a connecting line 13.
  • thermostatic valve 14 which closes the connecting line 13 as long as a cooling liquid in the lower channel system 5 has not reached a temperature close to the optimal operating temperature of the internal combustion engine 1.
  • Both the upper channel system 12 and the lower channel system 5 are supplied with coolant by a common pump 15.
  • a heat exchanger 23 provided for vehicle heating or the like, which is arranged parallel to the short-circuit line 20, is thus supplied with sufficiently heated coolant very quickly after the start of the internal combustion engine 1.
  • a drain 16 leads from the upper duct system 12 to a main thermostatic valve 17.
  • the main thermostatic valve 17 opens a line path 18 via a cooler 19 to the pump 15 at the operating temperature of the cooling liquid.
  • the partition 6 between the two channel systems 5 and 12 can, as can be seen in FIG. 2, be formed by a web made with the casting of the cylinder block 2.
  • a partition 6 is shown, which extends over an area 21, which corresponds approximately to the piston stroke, so that there are no coolant spaces in this area.
  • This version of the web is also made with the casting of the cylinder block 2.
  • a smaller amount of cooling liquid is required, so that the cooling liquid that is actually present is heated up to the operating temperature more quickly overall. The same advantageous effect occurs in an embodiment according to FIG.
  • FIG. 6 shows the arrangement of the thermostatic valve 14 in the connecting line 13 on the rear wall of the cylinder block 2.
  • the thermostatic valve 14 is inserted here from above into the connecting line 13 before the cylinder head 3 is attached.
