Definitions
- the invention relates to a liquid-cooled internal combustion engine having features of the Preamble of claim 1 specified type.
- the invention is based on a known from US 4055158 A internal combustion engine and in particular the device shown in Fig. 7 for cooling recirculated exhaust gas.
- This consists of a built-in an exhaust gas recirculation line heat exchanger, of Cooling water is flowed through, which is supplied via a line and a line is discharged.
- this heat exchanger flows through the pipe which is passed through pipes within it Exhaust.
- the invention is based on the idea of cooling the recirculated exhaust gas an already existing on the internal combustion engine, coolant-carrying component to use and this for the purpose of cooling recirculated exhaust gas accordingly new or redesign and equip.
- the heat exchanger according to the invention is here by an outside of the internal combustion engine existing section of a coolant-carrying Channels and implemented in this special cooling insert realized. Of the Channel section is through a cast, laterally next to the cylinder head or the Cylinder heads extending cooling fluid tube formed, for the installation of the cooling insert is transformed accordingly and in the cooling insert as a prefabricated unit can be installed in the manner of a cartridge.
- the cooling insert from a Bundles with a plurality of recirculated exhaust gas flow through the radiator tubes, whichdeerrohre niedes to an exhaust gas supply and others to a Abgasableit adopted connected and also each end by a plate or wall are passed liquid-tight, the coolant-carrying channel in the area of the cooling insert to the exhaust gas supply and Abgasableit styles seals off.
- the cooling insert but also from a single, in terms of his z.
- This cooling tube is one end to an exhaust gas supply device and the other to an exhaust gas discharge device connected and also liquid-tight end each by a plate or wall passed through the coolant-carrying channel in the area of the cooling insert seals to the exhaust gas supply and Abgasableit issued out.
- the cooling tube or each of the cooling tubes through a profile tube section formed, its length, cross-sectional size and shape and their number the amount of heat to be removed from the recirculated exhaust gas is turned off.
- Coolant is on the coolant return pipe with molded Zulaufkrümmer fed from the cylinder head internaldestattkeitslite and drain channels ago and then via one or more outlet nozzles from the channel after its Throughflow again discharged and a downstream organ such as thermostat and / or retarders.
- the design of the cooling insert in the manner of a cartridge allows complete prefabrication and a comparatively simple and quick installation of the same in the likewise prepared for this installation coolant return pipe.
- a section 1 of a line of the coolant circuit is a liquid-cooled one Internal combustion engine, shown as a diesel engine.
- This line section 1 is Coolant supplied according to arrow 2 via a connecting piece 3.
- To discharge the Coolant according to arrow 4 is at the line section 1 another connection piece. 5 available.
- This line section 1 limits as part of the device according to the invention a coolant-carrying channel 6 and is designed so that at least one cooling insert 7 can be installed or added.
- Such a cooling insert exists either from a single cooling tube 8, 9 (see Fig. 5 or 8) or a bundle of several Cooling tubes 10 (see Figs.
- a shut-off or throttle valve 25 may be installed, and is via an exhaust pipe 26th fed to an organ, with the combustion air / charge air and recycled, cooled Exhaust gas can be fed back to the internal combustion engine.
- On the cooling insert 7 can - as far as an optimization of the cooling liquid flow within the channel 6 necessary - one or a plurality of baffles 27 may be provided on the cooling tube 8, 9 and the radiator tubes 10th attached or arranged and in their configuration are only so large that they have a Einund Do not obstruct the removal of the cooling insert cartridge 7 into the line section 1.
- Figures 2 and 3 show the line section 1 in accordance with the invention by a cast coolant return pipe 28 is formed. Because in this essential parts constructive are identical to those parts of Figure 1, in Figures 2 and 3 are corresponding Parts with the same reference numbers, but provided with a high bar, marked.
- the coolant return pipe 28 extends laterally adjacent to a cylinder head or cylinder heads 29 of the further not shown internal combustion engine and is at this or Flanged this liquid-tight and in this mounting position by means of screws 30th held.
- the cooling liquid is supplied by cylinder head internal cooling chambers and drainage channels 31 ago over the cooling liquid return pipe 28 mitangegossene inlet manifold 3 'in the Channel 6 'fed and then after its flow from this again over a or more, not shown in Figure 2 and 3 discharge outlet and a downstream Organ supplied as thermostat and / or retarder.
- Into the coolant return pipe 28 is here, in contrast to the representation according to FIG. 1, only one cooling insert 7 'is used. built in the manner of a cartridge, so that in the end wall 15 'and only one opening a breakthrough 17 'is given for the installation and removal of the cooling cartridge 7'.
- the exhaust-side ends of the radiator tubes 10 'of the cooling insert 7' are here in a plate 11 ' liquid-tight, the two-sided supplement of seals together with the here one-piece, two-flow exhaust gas supply 12 'liquid-tight outside on the front page 15 'flanged and secured by means not shown screws.
- the cooling insert 7 or 7 ' can either only be a special one designed cooling tube 8 or 9 or a bundle of radiator tubes 10, 10 ', the or each of which is formed by a profile tube section.
- the length, cross-sectional shape and size as well as the number of cooling tubes is basically on the returned from the Exhaust gas during its flow through the cooling insert 7 or 7 'via the cooling liquid turned off amount of heat.
- FIG. 4 shows a bundle of nine cooling tubes 10, 10 'with circular cross-section.
- FIG. 6 shows a bundle of four cooling tubes 10, 10 '. with rectangular cross-section and also different cross-sectional sizes.
- FIG. 7 shows a bundle of four round cooling tubes 10, 10 'with annular cross-section.
- FIG. 8 shows a single cooling tube 9 with a substantially star-shaped cross section
- FIG. 5 shows a single cooling tube 8 with a round central tube and externally star-shaped cooling fins. It should be noted that Figures 4 to 8 are intended to show only examples for possible cooling tube design forms within a cooling insert 7, 7 '.
- the cooling of the recirculated exhaust gas with a device of according to the invention as follows.
- the recirculated exhaust gas is before its re-introduction in the combustion process of the internal combustion engine in the direction of arrow 32 via the exhaust gas supply 12, 12 'given in the coolant-carrying channel 6
- the so cooled back, recirculated exhaust gas is forwarded after its discharge from the cooling insert 7, 7 'and a corresponding recycling in the internal combustion engine supplied.
