Definitions
- the invention relates according to the preamble of claim 1 to a Liquid-cooled, multi-cylinder internal combustion engine with on-cylinder crankcase releasably arranged cylinder head comprising respectivedekarkammem in crankcase and cylinder head, wherein the coolant chamber in the cylinder head from its outer walls, a crankcase side floor plate and a spaced-apart top wall is limited, and by means of transverse walls is divided into sections assigned to each cylinder-side combustion chamber, wherein the in the sections of the cylinder head across flowing gas exchange channels and housings for spark plugs and / or injectors washing around Coolant adjacent in the bottom plate of a longitudinal side of the cylinder head arranged openings flows in the direction of the cylinder crankcase.
- Such an internal combustion engine shows and describes DE 196 08 576 C1, wherein the targeted in the cylinder head turbulent cross-flow is caused by the passage of coolant from a portion of a subdivided coolant chamber of the cylinder crankcase. About a special ventilation of the cross flowed through cylinder head, nothing is stated.
- the cylinder head known from DE 1 214 935 B1 shows a relative free arrangement of injector and / or spark plug on one longitudinal side.
- This is achieved in the liquid-cooled cylinder head characterized in that the the pump in the coolant space of the cylinder crankcase depressed coolant through openings in the bottom plate of this cylinder head in the Coolant chamber enters and a separate, inserted dip tube to a on the outside of the cylinder head arranged return line discharged to a radiator is.
- the invention is based on the object in a generic internal combustion engine the coolant guide with the involvement of at least one subarea a partitioned coolant chamber of the cylinder crankcase so to make that in a simple design effective ventilation of a transverse flowed through cylinder head is achieved.
- the solution according to the invention provides for this purpose that the cylinder crankcase divided into subregions Includes coolant chamber and that arranged in the cylinder crankcase Device for the forwarding of the effluent from the cylinder head coolant a built-in cylinder head riser is used, one in the cylinder head the Portions of this coolant chamber in high points connecting vent line is provided, in the connectable to an outer line connection riser in a region of a geodesic peak opens.
- the device is an in-cylinder crankcase separately trained or integrated collection channel.
- the one with the integrated riser channel in the cylinder head coolant-conducting connected collecting duct in the cylinder crankcase results in a cost-effective design without additional Components and advantageously increases the sound absorption on the cylinder crankcase.
- arranged on the inlet side in the cylinder crankcase Collector can cross-flow cylinder head from an outlet side Part of a subdivided coolant chamber of the cylinder crankcase supplied be and / or but by a arranged on the cylinder head longitudinal channel according to another proposal of the invention.
- this can be made relatively narrow, so that in Advantageously, only a minimal broadening of the cylinder head and the Cylinder crankcase results.
- the present invention arranged in the cylinder crankcase collecting duct eliminates such a device on the overlying cylinder head, so that at this for the arrangement of injectors in a preferred direct injection a significant constructive freedom is gained, which in particular for flat inclined arranged direct injectors is essential. Further can with the collecting channel arranged according to the invention, the heating of the Intake air and thus the filling loss can be reduced. Finally, it turns out a die-cast cylinder crankcase in low-cost Opereck execution.
- the collecting channel is on wall openings with a portion of the divided coolant chamber of the cylinder crankcase in connection.
- Collection channel is this on the wall openings with an inlet side Part of the coolant chamber of the crankcase in conjunction with the advantage that this portion in the full load operation of the internal combustion engine is rinsed.
- a suitable purging or purging of a outlet side portion of the subdivided coolant chamber can this at a Main supply by a arranged on the cylinder head supply longitudinal channel over a small number of openings of relatively small diameter be connected to the coolant chamber sections in the cylinder head.
- a reinforced fluid connection of such a subregion to the Collection channel is achieved in a further embodiment of the invention in that the Collecting channel over an open-plan longitudinal side with a portion of the subdivided Coolant chamber of the cylinder crankcase is in communication.
- All the aforementioned embodiments of the invention arranged collecting channel can be advantageously combined with a cylinder head at least arranged in an end region integrated riser.
- the cylinder head in both end regions respectively an integrated riser channel, with the advantage that for a transverse or longitudinal installation the engine each achieved an optimized radiator inlet connection is.
- this largely equal flow conditions in the differently arranged cylinder heads, wherein for both types of connections the radiator feed lines in each case an identical cylinder head in an advantageous manner Use finds.
- feature of the invention is the front Front side of the engine adjacent riser with a cylinder head Integrated short-circuit channel to a arranged on the cylinder head pump connection piece in connection. This is for a side of the engine arranged coolant pump an externally routed, over the front side the internal combustion engine routed away shorting line avoided and thus optionally shortens the length of the internal combustion engine.
- the invention is advantageously for a liquid-cooled internal combustion engine a uniform cylinder head for a longitudinally installed as well as for reaches a transversely mounted internal combustion engine, with which in the transverse flowed through cylinder head integrated vent line with a geodesic Peak point connection in at the integrated riser channel for each of the predetermined, Adequate ventilation during filling and a safer Steam extraction is ensured during hot operation of the internal combustion engine.
- a liquid-cooled, multi-cylinder internal combustion engine 1 is connected to an am Cylinder crankcase 2 releasably arranged cylinder head 3 equipped with respective Coolant chambers 4 and 5 in crankcase 2 and cylinder head.
- the coolant chamber 4 in the cylinder head 3 is of the outer walls, a crankcase side Base plate 6 and a spaced above it Cover wall 7 limited and by means not shown transverse walls in a respective cylinder-side Combustion chamber associated sections 8, 8 ', 8 ", 8' '' divided, the in the Sections 8 to 8 '' 'the cylinder head 3 across, not shown Gas exchange ducts and receptacles for spark plugs and / or injectors Coolant over in the bottom plate 6 a longitudinal side of the cylinder head. 3 adjacent openings 9 in the direction of the cylinder crankcase 2 drains off.
- Coolant chamber 5 includes and that arranged in the cylinder crankcase 2 Device 10 of the forwarding of the effluent from the cylinder head 3 coolant is used to an integrated in the cylinder head 3 riser 11, wherein a in the Cylinder head 3, the sections 8 to 8 '' 'of this coolant chamber 4 at high points connecting vent line 12 is provided which in the with an outer Line connection 13 connectable riser 11 in a range of geodesic Highest point 14 opens.
- the device 10 may be a cylinder crankcase 2 separately trained or integrated collection channel 15 be without connection to one of the subregions 5 ', 5 "of the coolant chamber 5 of the cylinder crankcase Second
- FIG. 1 shows a preferred embodiment of the collecting channel 15, wherein the preferably on the inlet side provided in the internal combustion engine 1 collecting duct 15 via wall openings 16 with an inlet-side portion 5 'of the subdivided Coolant chamber 5 of the cylinder crankcase 2 is in communication.
- Coolant chamber 5 of the cylinder crankcase 2 are used with the advantage a minimum of effort.
- an integrated riser channel 11 is arranged in the cylinder head 3 at least in one end region 18 or 18 '.
- an integrated riser channel 11 arranged with the advantage of a unitary cylinder head 3 for a longitudinally mounted Internal combustion engine 1 or for a transverse internal combustion engine 1 in a vehicle, not shown.
- At the outer line connection 13 of the front riser channel 11 may also be a tap be provided for a vehicle heating flow.
