Definitions

  • the invention relates to a Liquid-cooled, multi-cylinder internal combustion engine with a cylinder-crankcase detachably arranged cylinder head comprising respective coolant chambers in the crankcase and cylinder head, with the coolant chamber in the cylinder head of its outer walls, a crankcase-side base plate and a top wall spaced above it is limited, and by means of transverse walls is divided into sections each assigned to a cylinder-side combustion chamber, the gas exchange channels flowing across the cylinder head in the sections and receptacles for spark plugs and / or injection nozzles Coolant adjacent in the base plate of a long side of the cylinder head arranged openings flows towards the cylinder crankcase.
  • Such an internal combustion engine shows and describes DE 196 08 576 C1, wherein the desired turbulent cross-flow is caused by the transfer of coolant from a partial area of a divided coolant chamber of the cylinder crankcase. Via a special ventilation of the cross nothing flows through the cylinder head.
  • a liquid-cooled internal combustion engine is known from DE 195 08 985 C1 with a cylinder head for an inclined cylinder crankcase, whereby the coolant chamber of the cylinder head through an intermediate ceiling in superimposed Sections is divided. To vent this cylinder head with a subdivision of the coolant chamber provided in the machine longitudinal direction ventilation ducts extending over the length of the cylinder head are provided.
  • the cylinder head known from DE 1 214 935 B1 shows a relative free arrangement of injection nozzle and / or spark plug on one long side. This is achieved with the liquid-cooled cylinder head in that the coolant pressed into the coolant chamber of the cylinder crankcase through openings in the base plate of this cylinder head in the Coolant space enters and via a separate, inserted dip tube to one Return line arranged on the outside of the cylinder head is discharged to a cooler is. Furthermore, a geodetic high area of the cylinder head is a vent or a steam vent is provided in the dip tube.
  • DE 36 29 671 A1 describes a single cylinder head for a cylinder tube a liquid-cooled internal combustion engine known, which in one helical channel around the cylinder tube led coolant on the cylinder head side End via a riser duct built into the cylinder head to a die Single cylinder heads connecting manifold leads away. Venting measures the coolant rooms are not mentioned.
  • the invention has for its object in a generic internal combustion engine the coolant flow with the inclusion of at least one partial area to design a divided coolant chamber of the cylinder crankcase in such a way that with a simple design, an effective ventilation of a cross flowed through cylinder head is achieved.
  • the cylinder crankcase divided into sections Coolant chamber comprises and that one arranged in the cylinder crankcase Setting up the forwarding of the coolant flowing out of the cylinder head an ascending channel integrated in the cylinder head, one in the cylinder head Vent line connecting sections of this coolant chamber at high points is provided which in the riser duct connectable to an outer line connection culminates in an area of a geodetic peak.
  • the device is in the cylinder crankcase separately trained or integrated collecting channel.
  • the one with the Integrated ascending duct in the cylinder head connected collecting duct carrying coolant in the cylinder crankcase results in a cost-effective version without additional Components and advantageously increases the sound absorption on the cylinder crankcase.
  • the cross-flow cylinder head can collect from a discharge side Part of a divided coolant chamber of the cylinder crankcase supplied be and / or also through a longitudinal channel arranged on the cylinder head according to a further proposal of the invention.
  • a correspondingly deep training Collecting channel can be made relatively narrow, so that in advantageously only a minimal widening of the cylinder head and the Cylinder crankcase results.
  • the collecting duct is above wall openings with a portion of the divided coolant chamber of the cylinder crankcase in connection.
  • the collecting duct stands over the wall openings with an inlet side Part of the coolant chamber of the crankcase in connection with the advantage that this sub-area in full load operation of the internal combustion engine is rinsed.
  • a Main supply through a longitudinal supply duct arranged on the cylinder head over a small number of openings of a relatively small diameter be connected to the coolant chamber sections in the cylinder head.
  • collecting channel is achieved in that the Collection channel over an openly designed long side with a section of the subdivided Coolant chamber of the cylinder crankcase communicates.
  • a partial area of a coolant chamber preferably subdivided by the cylinders serve the cylinder crankcase.
  • All of the aforementioned configurations of the collecting duct arranged according to the invention can advantageously be combined with at least one in the cylinder head integrated ascending duct arranged in an end region.
  • the cylinder head has in both end regions an integrated riser, with the advantage that for transverse or longitudinal installation the internal combustion engine each achieved an optimized radiator flow connection is. This advantageously results in largely the same flow conditions in the differently arranged cylinder heads, whereby for both types of connection the radiator supply lines each have the same cylinder head in an advantageous manner Is used.
  • that of the front Front side of the internal combustion engine has an adjacent riser duct with one in the cylinder head Integrated short-circuit duct to a pump connection piece arranged on the cylinder head in connection. This is for one on the side of the internal combustion engine arranged coolant pump an externally laid, over the front the short-circuit line to be led away from the internal combustion engine and thus if necessary, shortens the overall length of the internal combustion engine.
  • the invention is advantageous for a liquid-cooled internal combustion engine a uniform cylinder head for a longitudinally installed as well as for reached a transversely installed internal combustion engine, with which in the transversely flowed through cylinder head integrated ventilation line with a geodetic Peak connection in on the integrated riser for each of the predetermined a safe ventilation when filling as well as a safe Steam extraction is ensured during hot operation of the internal combustion engine.
  • the coolant chamber 4 in the cylinder head 3 is from the outer walls, a crankcase side Base plate 6 and a spaced above it Cover wall 7 limited and by means of transverse walls, not shown, in one cylinder side Sections 8, 8 ', 8' ', 8' '' assigned to the combustion chamber are subdivided; Sections 8 to 8 '' 'through the cylinder head 3, not shown Gas exchange channels and receptacles for spark plugs and / or injection nozzles Coolant in the bottom plate 6 of a long side of the cylinder head 3 perforations 9 arranged adjacent in the direction of the cylinder crankcase 2 flows off.
  • the invention proposes that the cylinder head crankcase 2 divided into sections 5 ', 5' ' Coolant chamber 5 includes and that one arranged in the cylinder crankcase 2 Device 10 for forwarding the coolant flowing out of the cylinder head 3 to an integrated in the cylinder head 3 riser 11, one in Cylinder head 3 sections 8 to 8 '' 'of this coolant chamber 4 in high points connecting vent line 12 is provided, which in the with an outer Line connection 13 connectable riser 11 in a geodetic area Peak 14 ends.
  • the device 10 can be in a cylinder crankcase 2 separately trained or integrated collection channel 15 without connection to one of the partial areas 5 ', 5' 'of the coolant chamber 5 of the cylinder crankcase 2nd
  • FIG. 1 shows a preferred embodiment of the collecting duct 15, the preferably provided on the inlet side in the internal combustion engine 1 collection channel 15 through wall openings 16 with an inlet-side portion 5 'of the divided Coolant chamber 5 of the cylinder crankcase 2 is connected.
  • the collecting duct 15 can be open via a designed long side with a portion 5 'or 5' 'of the divided coolant chamber 5 of the cylinder crankcase 2 are connected.
  • Coolant flowing out of the cylinder head 3 can be passed on Device 10 is a partial area 5 ′ or 5 ′′ of a section divided over the cylinders 17 Coolant chamber 5 of the cylinder crankcase 2 serve the advantage the least effort.
  • Supply longitudinal channel to be supplied can according to the DE 198 02 060 can be formed.
