Definitions

  • the present invention relates to an internal combustion engine having a housing and at least one cavity arranged therein for flowing through by means of a cooling liquid for cooling the internal combustion engine and with an exhaust gas cooler for cooling exhaust gas to be supplied by a combustion process, according to the preamble of claim 1.
  • Exhaust gas coolers are used today to significantly reduce nitrogen oxide and particulate emissions.
  • a part of the exhaust gas is branched off in the exhaust manifold and then passed through the exhaust gas cooler and cooled.
  • the cooled exhaust gas is then mixed with fresh air sucked in and recirculated as a mixture of the internal combustion engine. Due to the comparatively high exhaust gas temperatures such an exhaust gas cooler is exposed to a high thermal load, wherein the cooler must be dimensioned and designed in any case so that it does not come to damage due to the comparatively high exhaust gas temperatures.
  • exhaust gas coolers are either screwed directly to the internal combustion engine via holders or mounted on solid holders and then fixed with straps.
  • the exhaust gas cooler has a housing in which exhaust-gas-carrying tubes are installed, which in turn are flowed around by cooling liquid.
  • a clear simplification are exhaust gas cooler, which are integrated in a cavity of a housing of the internal combustion engine, such as an engine block or a crankcase, and thereby can be connected directly to the cooling system of the internal combustion engine.
  • the EP 1 099 847 A2 is a generic internal combustion engine with a housing and disposed therein cavities for flowing by means of a Coolant for cooling the internal combustion engine known.
  • the internal combustion engine also has an exhaust gas cooler for cooling exhaust gas to be supplied to a combustion process.
  • an oil cooler is additionally integrated into the cooling circuit of the internal combustion engine, wherein the exhaust gas cooler is further away from a main cooling liquid flow than the oil cooler, which involves the risk that not enough cooling fluid flows through the exhaust gas cooler. Rather, the exhaust gas cooler is even something out and here forms a dead space. This should limit the thermal durability.
  • an internal combustion engine with a crankcase and a cylinder head is known to which an exhaust manifold and a fresh gas line are attached. These two lines are connected via an exhaust gas recirculation line with switched on in the exhaust gas recirculation line exhaust gas recirculation valve with an exhaust gas cooler.
  • the housing of the exhaust gas cooler is at least in a partial area an integral part of the crankcase.
  • a disadvantage of today's exhaust gas coolers is that they are comparatively expensive and are constructed with many components even at low power requirements of the respective exhaust gas cooler.
  • the high costs are in particular a comparatively expensive housing, which is up to 2 mm thick.
  • the present invention deals with the problem for an internal combustion engine of the generic type an improved or at least an alternative Specify embodiment, which allows effective and cost-effective exhaust gas cooling.
  • the present invention is based on the general idea to position an exhaust gas cooler in a arranged in a housing of a corresponding internal combustion engine cavity and thereby to integrate directly into a coolant circuit of the engine and a specially designed spacer element and thus optimized in terms of heat transfer in the cavity of To arrange internal combustion engine.
  • the internal combustion engine according to the invention has a housing with cavities arranged therein, which are flowed through by cooling liquid and above which cool the internal combustion engine.
  • the internal combustion engine according to the invention has an exhaust gas cooler for cooling exhaust gas to be supplied to a combustion process.
  • the exhaust gas cooler is designed as a stacked disc radiator with at least two stacking disks, a cover plate and a screw-on plate for screwing onto the housing of the internal combustion engine. In the state screwed to the housing, the exhaust gas cooler protrudes into a cavity of the housing of the internal combustion engine through which the cooling fluid flows.
  • the spacing element can be a separate spacer, such as a metal ring, a bush or a sheet metal part, and it is also conceivable that the spacer element is designed as a cup formed from the screw-on plate and thus integrally formed with the screw-on plate. The latter is the preferred embodiment, since this is inexpensive and can be realized without further installation effort. In a separate embodiment of the spacer element, this is with adjacent components, in particular with the mounting plate, connected, for example, soldered, welded or screwed. Both the cup and the separate spacer increase a distance between the mounting plate and the adjacent stacking disk and thereby position the exhaust gas cooler deeper in the cavity.
  • the exhaust gas cooler or its stacking disks in the cavity Due to the lower positioning of the exhaust gas cooler or its stacking disks in the cavity, it can be better flowed around by the cooling liquid and thus the exhaust gas flowing therein can be cooled.
  • the spacer element realized according to the invention at the exhaust gas inlet the inlet region of the exhaust gas can be flowed around much better by cooling liquid, whereby the thermal resistance to change and the life expectancy of the exhaust gas cooler can be increased.
  • At least the stacking disks and the mounting plate are soldered, welded or screwed together.
  • a complete soldering of both the stacking disk block with the individual stacking disks as well as the mounting plate or the cover plate with the stacking disk block is particularly preferred.
  • a prefabrication of the exhaust gas cooler is possible.
  • the spacer element is at the same time designed as a flow guide.
  • the spacer element may be formed as a flow guide and thereby avoid in particular so-called dead zones.
  • a uniform flow through the exhaust gas cooler can be forced by a spacer formed as a flow guide, whereby a high heat transfer and thus an effective exhaust gas cooling are possible.
  • the spacer element outside a microwave fixture structure in particular beads, knobs or Ribs, has.
  • the heat transferring surface can be increased and the heat exchange can be improved.
  • the depth a of the spacer element is at least 5 mm.
  • a particularly good rinsing of the spacer element with coolant and thus optimum cooling thereof takes place, which in turn increases the thermal resistance to change.
  • a distance b between an exhaust duct formed by two stacking disks and the screw-on plate is at least 8 mm.

  • This can of course also be designed as a separate spacer analogous to the cup at the exhaust inlet. This makes it possible to collect the exiting the exhaust gas cooler and cooled exhaust gas at the outlet side in an impressed in the Anschraubplatte Abgasumlenkkanal and, for example, pass directly to a Abgasüberströmkanal in the internal combustion engine and to direct to the cold side of the engine.
  • an exhaust gas return valve is arranged on the mounting plate in the region of an exhaust gas inlet, which in particular arranged on the mounting plate Threaded bolt is screwed.
  • Threaded bolt is screwed.
  • These threaded bolts can for example be welded to the connection plate and allow a comparatively simple pre-assembled of the exhaust gas recirculation valve to the connection plate.
  • a screw connection of the exhaust gas recirculation valve via the threaded bolt arranged on the mounting plate also makes it possible for the exhaust gas recirculation valve to be indirectly fixed via the threaded bolts and the mounting plate on the engine, ie on the internal combustion engine, whereby the vibration transmission to the stacking disk block is at least reduced.

  • the stacking disks 5, that is to say the heat exchanger block of the exhaust gas cooler 4 flow better through the cooling liquid 12 and thus also be better cooled.
  • the spacer element 9 can either as as from the mounting plate 7 integrally formed cup 24 (see. Fig. 2 ), or it is a separate spacer 25 (see. Fig.
  • the mounting plate 7 in particular screwed, soldered or welded. Additionally or alternatively, it may also be connected to the first stacking disk 5.
