Definitions

  • the invention relates to an internal combustion engine with several water-cooled and V-shaped arranged cylinders of a cylinder crankcase, in particular a motor vehicle, with a V space formed in the V between the cylinder rows forming the V, with coolant jackets associated with respective cylinders, the coolant from the coolant jackets into respective cylinder heads and out of these via respective coolant outflow openings back into the cylinder crankcase in a coolant return channel arranged in the V-space flows, according to the preamble of claim 1.
  • EP 0 637 682 B1 describes a water-cooled multi-cylinder internal combustion engine with a V-shape arranged rows of cylinders known, in the V-space side by side The following is seen lying from the inside outwards, a water supply, pump receiving bores for respective fuel injection pumps, coolant longitudinal channels, Valve tappet guides and coolant jackets for the cylinders. However, all of this is in one piece with the cylinder crankcase designed so that this arrangement is expensive to manufacture and is expensive.
  • DE 41 36 773 C1 describes a distributor housing for a V internal combustion engine, wherein in the V-space a distributor housing with a flat base plate on a flange of the crankcase the internal combustion engine is arranged.
  • This distributor housing integrated a large number of components usually taken over from separately arranged components Functions.
  • the distributor housing leads in particular cooling water flows of the internal combustion engine, but only connecting flanges are provided and the coolant channels themselves are to be completely formed in the cylinder crankcase. Only a water guide housing is completely formed in the distributor housing, which however only serves as a holder for a thermostat and a water pump and none at all Distribution function for the cooling water fulfilled.
  • DE-OS-2 015 546 describes an internal combustion engine with rows of cylinders arranged in a V-shape known, with respective cooling jackets of the cylinder block and cylinder head together keep in touch. Furthermore, a multiple connector is arranged in the V space, which Channels for the supply of a fuel-air mixture and for the removal of exhaust gases to care. At one end of the multiple connector are connections for coolant channels intended. This arrangement is due to the execution in several discrete elements however, complicated to manufacture and assemble and expensive. It also flows Coolant on one side from part of the multiple connector in the cylinder block on, crosses it completely along the rows of cylinder heads and only flows afterwards again from the cylinder block into another part of the multiple connector. Thereby the problem of uneven cooling mentioned above also arises here of the cylinder block.
  • the present invention is therefore based on the object of an improved internal combustion engine to provide the above type, the above Disadvantages are overcome and a compact design for the coolant system optimal use of the V-space is achieved.
  • one with the coolant return channel in the V-space and the mixing chamber connected to the coolant outflow openings of the cylinder heads immediately adjacent to an outer wall of the coolant jacket of the cylinder is.
  • the mixing chamber is open on a side adjacent to the V-space is, wherein a cover is arranged such that it has a coolant inlet channel in the V-space forms and a means for selectively connecting the coolant inlet channel with the Mixing chamber is provided, can be achieved in a simple manner with a small space requirement a coolant management system by simply placing a cover on the V space.
  • a bypass in the cooling circuit immediately and without additional measures arranged cooler designed so that in operating phases in which the internal combustion engine does not have a predetermined operating temperature, the cooler bridges and thereby quickly reaching the predetermined operating temperature for the first time or again can.
  • a simple and inexpensive arrangement is achieved in that the means for A map thermostat optionally connects the coolant inlet channel to the mixing chamber is.
  • a W-shaped arrangement of the cylinders with a correspondingly compact design of the internal combustion engine is achieved in that two rows of cylinders of the V-shaped arrangement each themselves are arranged in a V-shape.
  • the cover is also designed such that it is integral has a coolant inlet which is connected to the V-space closed by the cover is, and in a preferred manner the cover is additionally designed such that it integrally has the coolant return channel connected to the mixing chamber.
  • a temperature sensor is expediently additionally arranged on the cover, which in the coolant return duct protrudes into it.
  • FIG. 1 shows an example of 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 includes respective cylinder heads 22 and 24, coolant jackets 26 and 28, Coolant inflow openings 30, via the coolant in the direction of arrow 31 into the cylinder heads 22, 24 flows, and coolant outflow openings 32, via the coolant from the cylinder heads 22, 24 flows out again in the direction of arrow 33.
  • a mixing chamber 34 is integral with the cylinder crankcase Formed walls 36 and bounded by walls 38 of the coolant jackets 26, 28.
  • the mixing chamber 34 also has an opening on a side facing the V-space 35 40 on.
  • a cover 42 closes the V-space 35 and thus forms a coolant inlet channel in it 44 out.
  • the cover 42 additionally comprises a means 46, for example in the form of a Map thermostats, which either opens or closes the opening 40 and thus selectively connects the mixing chamber 34 to the coolant inlet channel 44.
  • Coolant flows into the mixing chamber 34 via the coolant outflow openings 32 Cylinder heads 22, 24 a.
  • the mixing chamber 34 is additional connected to a coolant return channel 48 through which the coolant does not go to one shown heat exchanger, for example in the form of a cooler, flows.
  • coolant flows at least partially bypassing the cooler directly into the coolant supply duct 44, if the means 46 opens the opening 40, as indicated by arrow 47.
  • the coolant becomes cylinders by means of channels 50 or their coolant jackets.
  • coolant return duct 48 and a coolant inlet 52 are formed integrally with the cover 42, so that by simply putting the cover 42 on the V-space 35 with one hand automatically and without further measures coolant inlet 52, coolant inlet channel 44, Mixing chamber 34 with optionally openable opening 40 and coolant return channel 48 are trained.
  • the cover 42 additionally includes a temperature sensor 54, which in the coolant return channel 44 protrudes into it and determines the temperature of the coolant there and depending on it from this temperature the means 46 for selectively opening or closing the opening 40 controls.
  • a coolant pump 56 arranged at the end also ensures a corresponding one Coolant flow.
  • the coolant enters the cylinder crankcase via the coolant pump 56 20 and is distributed there to the coolant jackets 26 and 28 of the cylinders 12 to 18.
  • the coolant then flows through a cylinder head gasket 58 (FIG. 1) and the Coolant inflow openings 30 in the direction of arrow 31 into the cylinder heads 22 and 24 this in a cross flow and continues to flow through coolant outflow openings 32 below inlet flanges 60 of the cylinder heads 22 and 24, in turn, via the cylinder head gasket 58 into the mixing chamber 34 and thus gets back into the cylinder crankcase 20.
  • This arrangement prevents the coolant from escaping from the front Cylinder heads.
  • the cover 42 has a multiple function: it takes the thermostat 46, closes the V-space 35 and at the same time picks up the temperature sensor 54 and integrally forms a nozzle 62 for the radiator flow and a nozzle 64 for the radiator return.
