Definitions

  • the invention relates to an internal combustion engine having a plurality of water-cooled and V-shaped cylinders of a cylinder crankcase, in particular of a motor vehicle, with a trained V V-space between the V-forming cylinder rows, associated with respective cylinders coolant shells, wherein the coolant from the coolant shells into respective Cylinder heads and flows from these via respectiveméffenabströmö réelleen back into the cylinder crankcase in a arranged in V-space coolant return passage and wherein in the V space connected to the coolant return passage and thedekarabströmö Stamm the cylinder heads mixing chamber immediately adjacent to an outer wall of the coolant jacket of the cylinder is formed according to the preamble of claim 1.
  • a generic internal combustion engine is known from DE 40 01 140 C1.
  • common coolant supply lines and coolant discharges from which branch off the lines for each cylinder, formed in the inner free V-angle of the cylinder block as in the cylinder block longitudinal direction adjacent, open to the V-end, closable by a lid channels.
  • EP 0 637 682 B1 discloses a water-cooled multi-cylinder internal combustion engine with cylinder rows arranged in a V-shaped manner, wherein the following is formed in the V-space in a fan-like manner next to one another from inside to outside, a water feed, pump receiving bores for respective fuel injection pumps, longitudinal coolant ducts, valve tappet guides and coolant jackets of the cylinders. All this, however, is formed integrally with the cylinder crankcase, so that this arrangement is complicated and expensive to manufacture.
  • DE 41 36 773 C1 describes a distributor housing for a V-type internal combustion engine, wherein a distributor housing is arranged with a flat base plate held on a flange of the crankcase of the internal combustion engine in the V-space.
  • This distributor housing integrates a variety of commonly accepted by separately arranged components functions.
  • the distributor housing in particular leads cooling water flows of the internal combustion engine, but only connecting flanges are provided and the coolant channels themselves are to be formed completely in the cylinder crankcase. Only a water guide housing is completely formed in the distributor housing, which, however, serves only as a receptacle for a thermostat and a water pump and does not fulfill any distribution function for the cooling water.
  • the present invention is therefore based on the object to provide an improved internal combustion engine of the type mentioned above, wherein the above-mentioned disadvantages are overcome and for the coolant system, a compact design and optimum use of the V-space is achieved.
  • the mixing chamber is open on a side adjacent to the V-space side, wherein a cover is arranged such that it forms a coolant inlet channel in the V-space and provides a means for selectively connecting the coolant inlet channel with the mixing chamber is.
  • a coolant supply system by simply placing a lid on the V-space.
  • a bypass of a cooler arranged in the cooling circuit is formed immediately and without additional measures, so that in operating phases in which the internal combustion engine does not have a predetermined operating temperature, the radiator bridges and thereby quickly the predetermined operating temperature can be achieved for the first time or again.
  • side walls of the coolant channels are combined composed of cover elements and cylinder head housing elements, resulting in a further simplification of the arrangement or assembly and also later possibly required maintenance. Namely, the mixing chamber and the coolant inlet channel are accessible at any time for maintenance or test purposes by simply disassembling the lid.
  • a simple and inexpensive arrangement is achieved in that the means for selectively connecting the coolant supply channel with the mixing chamber is a map thermostat.
  • a W-shaped arrangement of the cylinder with a correspondingly compact design of the internal combustion engine is achieved in that two rows of cylinders of the V-shaped arrangement are each themselves in turn arranged V-shaped.
  • the lid is further formed to integrally have a refrigerant inlet connected to the V-space closed by the lid, and preferably, the lid is additionally formed so as to integrally connect the refrigerant return passage connected to the mixing chamber having.
  • a temperature sensor is additionally arranged on the cover, which protrudes into the coolant return channel.
  • FIG. 1 shows by way of example an internal combustion engine 10 with a W-shaped cylinder arrangement of cylinders 12, 14, 16 and 18 in a cylinder crankcase 20.
  • the internal combustion engine 10 further comprises respective cylinder heads 22 and 24, coolant jackets 26 and 28, coolant inflow openings 30 via the coolant flows in the direction of arrow 31 in the cylinder heads 22, 24, andméffenabströmö réelleen 32, flows through the coolant from the cylinder heads 22, 24 in the direction of arrow 33 again.
  • a mixing chamber 34 is bounded by walls 36 integrally formed with the cylinder crankcase and by walls 38 of the coolant jackets 26, 28.
  • the mixing chamber 34 further has an opening 40 on a side facing the V-space 35.
  • a cover 42 closes the V-space 35 and thus forms in this a coolant inlet channel 44.
  • the cover 42 additionally comprises a means 46, for example in the form of a map thermostat, which opens or closes the opening 40 selectively and thus selectively connects the mixing chamber 34 with the coolant inlet channel 44.
  • Coolant flows into the mixing chamber 34 via the coolant outflow openings 32 from the cylinder heads 22, 24.
  • the mixing chamber 34 is additional connected to a coolant return passage 48, via which the coolant flows to a heat exchanger, not shown, for example in the form of a radiator.
  • coolant flows at least partially bypassing the radiator directly into the coolant inlet channel 44 when the means 46 releases the opening 40, as indicated by an arrow.
  • the coolant is passed by means of channels 50 respectively to cylinders or their coolant shells.
  • one of the channels 50 is connected to the coolant jackets 26 of the cylinders 1 to 4 and the corresponding other passage 50 is connected to the coolant jackets 28 of the cylinders 5 to 8.
  • the coolant return channel 48 and a coolant inlet 52 are integrally formed with the lid 42 so that by simply placing the lid 42 on the V-space 35 with a handle automatically and without further measures coolant inlet 52, coolant inlet channel 44, mixing chamber 34 with optional releasable opening 40th and coolant return channel 48 are formed.
  • the lid 42 additionally comprises a temperature sensor 54, which projects into the coolant return passage 44 and determines the local temperature of the coolant and, depending on this temperature, drives the means 46 for selectively opening or closing the opening 40.
  • a front side arranged coolant pump 56 also ensures a corresponding coolant flow.
  • the coolant enters the cylinder crankcase 20 via the coolant pump 56 and is distributed there to the coolant jackets 26 and 28 of the cylinders 12 to 18. Subsequently, the coolant flows via a cylinder head gasket 58 (FIG. 1) and the coolant inflow openings 30 into the cylinder heads 22 and 24 in the direction of arrow 31, traverses them in a transverse flow and then flows on via coolant outflow openings 32 below inlet flanges 60 of the cylinder heads 22 and 24 again the cylinder head gasket 58 into the mixing chamber 34 and thus returns to the cylinder crankcase 20.
  • a cylinder head gasket 58 FIG. 1
  • the lid 42 has a multiple function: it receives the thermostat 46, closes the V-space 35 and at the same time receives the temperature sensor 54 and integrally forms a nozzle 62 for the radiator feed and a nozzle 64 for the radiator return.
