  • the invention relates to a device and According to the preamble of claim 2, a method for cooling returned Exhaust gas from a liquid-cooled internal combustion engine with exhaust gas recirculation device.
  • a device solved, namely by a cooling insert in a liquid-carrying Channel of the internal combustion engine and a corresponding design of the channel component in the area of the cooling insert for cooling the Recirculated exhaust gas flowing through the cooling insert through the exhaust gas flowing through the channel Coolant.
  • the stated object is achieved on the other hand by a method according to Claim 2 solved, such that the recirculated exhaust gas before it is reintroduced in the combustion process of the internal combustion engine by one in one coolant-carrying channel arranged cooling insert passed and thereby through the coolant of the internal combustion engine flowing through the channel is cooled.
  • the invention is therefore based on the idea of cooling the recirculated Exhaust gas already present on or in or in the vicinity of the internal combustion engine to use the coolant-carrying component and this for the Purpose of cooling the recirculated exhaust gas only accordingly and equip.
  • Coolant channel for the installation or attachment of a cooling insert and, if necessary, change this purpose accordingly or redesign.
  • the coolant-carrying duct with the cooling insert can also be used outside arranged of the internal combustion engine and on or in a coolant line or a section thereof can be realized, for example in Area of the cylinder head next to this or in the area between a coolant pump and the crankcase or in the area between the coolant pump and a cooler upstream of the internal combustion engine or in the area between Internal combustion engine and a retarder operated with the coolant.
  • the channel with the cooling insert can also be placed in or on one redesigned component of the coolant circuit of the internal combustion engine, such as a coolant pump, Thermostat, switching valve, expansion tank and the like, or a retarder or a structural one with one of these components Form unity.
  • the cooling insert can consist of a bundle with several of recirculated exhaust gases flowable cooler pipes exist, which cooler pipes one end Exhaust gas supply device and other connected to an exhaust gas discharge device and also liquid-tight at each end by a plate or wall are passed through the coolant channel in the area of Seals cooling insert to the exhaust gas supply device and exhaust gas discharge device.
  • the cooling insert can, however, also consist of a single one its z.
  • This cooling pipe is one end of an exhaust gas supply device and another end connected to an exhaust gas discharge device and also at the end each liquid-tight through a plate or wall, which the coolant-carrying channel in the area of the cooling insert to the exhaust gas supply device and seals exhaust gas outlet.
  • the cooling tube or each of the Cooling tubes formed by a section of section tube, its length, cross-sectional size and shape and their number to be removed from the recirculated exhaust gas Amount of heat is turned off.
  • the device according to the invention is that the channel with the cooling insert in a cast coolant return pipe is realized, which is next to the side extending to the cylinder head or the cylinder heads of the internal combustion engine this or these is flanged, the coolant in the channel via on Coolant return pipe with molded inlet elbow from inside the cylinder head Cooling liquid spaces and drainage channels are fed in and then via one or several outlet nozzles out of the channel after it has flowed through it sent to a subordinate body such as a thermostat and / or retarder becomes.
  • a subordinate body such as a thermostat and / or retarder becomes.
  • the cooling insert is designed like a cartridge, what a complete prefabrication of the same and a comparatively simple and quick installation in those also prepared accordingly for this installation allows coolant-carrying channel.
  • a section 1 of a line is shown, which at any point of the Coolant circuit of a liquid-cooled internal combustion engine, such as a diesel engine, or the coolant circuit of one with coolant as the working fluid operated retarder can be arranged.
  • This line section 1 will Coolant is supplied according to arrow 2 via a connecting piece 3.
  • the coolant according to arrow 4 is a further connection piece on line section 1 5 available.
  • This line section 1 limits as part of the invention Device has a coolant channel 6 and is designed that at least one cooling insert 7 is installed or added can.
  • Such a cooling insert either consists of a single cooling tube 8, 9 (see Fig. 5 or 8) or a bundle of several cooling tubes 10 (see Fig.
  • the one or the one ends through a plate or wall 11 liquid-tight passed through and connected to an exhaust gas supply device 12 or are.
  • the other end is the cooling pipe 8, 9 or the cooling pipes 10 are through a plate or wall 13 passed liquid-tight and to an exhaust gas discharge device 14 connected.
  • the line section 1 in its front end wall 15 and rear end wall 16 two openings each or breakthroughs 17, 18, wherein the axes of the opposite one another Openings or openings are aligned with each other. This makes it possible that each a prefabricated cooling insert 7 in the manner of a cartridge through the Opening 17 and the channel and with the plate 13 in the opposite aligned opening 18 is immersed in a liquid-tight manner.
  • a shut-off or throttle valve 25 can be installed, and is supplied via an exhaust pipe 26 to an organ with which combustion air / charge air and recirculated, cooled exhaust gas back to the internal combustion engine is feedable.
  • On the cooling insert 7 - so far for an optimization of the coolant flow necessary within channel 6 - one or more baffles 27 be provided, which are attached to the cooling pipe 8, 9 or the cooling pipes 10 or arranged and are so large in their configuration that they can be installed and removed the cooling insert cartridge 7 in the line section 1 does not hinder.
  • FIGS 2 and 3 show the line section 1 formed by a cast Coolant return pipe 28. Because this is structurally identical parts with those parts of the solution according to Figure 1, the corresponding in Figures 2 and 3 Parts with the same reference numerals but with a prime are used.
  • the coolant return pipe 28 extends laterally next to a cylinder head or cylinder heads 29 of the internal combustion engine, also not shown and is flanged to this or these in a liquid-tight manner and in this Mounting position held by screws 30.
  • the coolant return pipe 28 in contrast to the solution according to FIG. 1, is only one Cooling insert 7 'installed like a cartridge, so that in the end wall 15' only one opening or opening 17 'for the installation and removal of the cooling insert cartridge 7 'is given.
  • the cooling insert 7 or 7 ' can either be only one have specially designed cooling pipe 8 or 9 or a bundle of cooling pipes 10, 10 ', that or each of them is formed by a profile tube section.
  • the length, cross-sectional shape and size as well as the number of cooling tubes is fundamental to the from the recirculated exhaust gas as it flows through the Cooling insert 7 or 7 'turned off via the amount of heat to be dissipated.
  • Figure 4 shows a bundle of nine cooling tubes 10, 10 'with an annular Cross-section.
  • Figure 6 shows a bundle of four cooling tubes 10, 10 'with a rectangular Cross section and also different cross section sizes.

  • FIG. 8 shows a single cooling tube 9 with an essentially star-shaped cross section and FIG. 5 shows a single cooling tube 8 with a round central tube and a star shape on the outside protruding cooling fins. It should be noted that Figures 4 to 8 are only examples should show for possible cooling pipe designs within a Cooling insert 7, 7 '.
  • the method according to the invention for cooling the recirculated exhaust gas arises with a device of the type according to the invention as follows Exhaust gas is released before it is reintroduced into the combustion process of the internal combustion engine according to arrow 32 via the exhaust gas supply device 12, 12 'in the coolant-carrying Channel 6 given cooling insert 7, 7 'and fed through whose cooling tube 8, 9 or cooler tubes 10, 10 'passed and thereby through the the cooling liquid flowing through the channel 6 and rinsing the cooling pipe or the cooling pipes chilled. Then the so cooled, recirculated Exhaust gas after discharge from the cooling insert 7, 7 'passed on for corresponding Recycling in the internal combustion engine.
