Definitions
- the invention relates to a device for gas recirculation in a Internal combustion engine, in particular of exhaust gas or the gas of a crankcase ventilation, according to the preamble of the main claim.
- the invention is based on the object, a device for recycling of exhaust gases so that there is no significant pollution more comes and this device takes up a small footprint.
- the task is characterized by the characterizing features of the independent Claim 1 solved.
- the inventive device of the type specified is advantageous Way designed so that space-saving a filter element in the connection flange the suction device is arranged. This further simplifies also the installation effort.
- Filter medium may preferably be a high temperature resistant medium, e.g. one Stainless steel pressed, to be provided.
- Filter medium By the possibly to be expected high pollution could filter element to be monitored anyway Air filter change interval to be changed.
- a cyclone the Be filter element upstream.
- This cyclone removes coarse soot particles and thus contributes to the filter element having a longer service life.
- a cyclone as a filter element use and provide no additional filter. In this case it is expedient to use a Mehrzellenzyklon, which is a high Has separation efficiency.
- a further advantageous embodiment of the invention can be seen therein that the cleaning is done by electrical energy. Periodically is by applying an electrical voltage, the filter medium heated above the firing temperature of the soot and the soot burned.
- the Combustion gases can via a corresponding line to the exhaust duct the internal combustion engine are supplied.
- Another alternative to the circuit of the filter element is available through an electrostatic precipitator. This has a very high separation efficiency and a low ⁇ p. Also the electrostatic precipitator can be cleaned by heating.
- a development of the invention lies in the use of an exchangeable filter for the filter element.
- the replacement of the filter element within a certain maintenance cycle can be done easily, is the filter element arranged in a detachable removable filter.
- This change filter is similar to an oil filter and can be easily, for example Dispose of thermally.
- Embodiments of the device according to the invention for exhaust gas recirculation in an internal combustion engine is based on the following figures explained.
- FIG. 1 shows a section through a device 1 for cooling exhaust gas an exhaust gas recirculation 2 for an internal combustion engine, not shown here shown.
- the exhaust gas flows through in the return 3 according to the arrow a filter element 4 to a connection flange 5 at the not shown here Intake device 6 of the internal combustion engine.
- the filter element 4 Through the filter element 4, the recirculated gas is freed from Abgäsruß and only the purified hot exhaust gas to the internal combustion engine or the Suction tube supplied.
- the filter element 4 has here as a filter medium high-temperature resistant material, namely a stainless steel pressed on and is executed as an inline filter.
- the filter element can also in the exhaust gas recirculation of the Intake manifold integrated. Furthermore, the filter element described above 4 also arranged in a gas supply of a crankcase ventilation become.
- the connecting flange 5 according to FIG. 1 is thermally insulated on the intake device 6 arranged.
- the exhaust gas recirculation pipe 7 is provided with a sleeve 8 provided, this sleeve has contact with the flange 5.
- Sleeve 8 and exhaust gas recirculation pipe is another in the outlet region of the tube thermally from the exhaust gas recirculation pipe 7, substantially Gentkoppelte, Sleeve 9 is provided. The exiting exhaust gas flows without heating the closer Surround the suction device 6 in the collector for the intake air one.
- Figure 2 shows a cleanable filter element 4, this consists of a Steel knit 5 on which the soot particles of the exhaust gas accumulate.
- a cleanable filter element 4 consists of a Steel knit 5 on which the soot particles of the exhaust gas accumulate.
- to Cleaning of the steel mesh 12 is this with a not shown here Voltage source connected via the terminals 10 and 11.
- the steel mesh heats up 12 to above the ignition temperature of the deposited soot.
- the soot is burned and the resulting combustion gases are over a flow reversal and a flow according to the arrows 13, 14th fed to the exhaust gas of the internal combustion engine.
- FIG. 3a shows the production of the filter element 4 from, for example, a Steel fabric.
- this is a wire conductor 15 consisting of a Variety of individual wires with the electrical connections 10 and 11.
- This wire conductor is inserted into the housing 16 of the filter element and the housing is closed.
- the wire conductor can be easier to service for maintenance Be removed from the case and a new wire conductor can be insert easily (Figure 3b).
- FIG 4a shows a schematic representation of an exchangeable filter in which a steel knit 12 is arranged.
- This replaceable filter 16 is at a Filter head 17 attached to the input 18 and the output 19 for the exhaust gas is connected.
- FIG. 4b likewise shows a replaceable filter 16 in a schematic representation wherein in the filter head 17 in addition to the ports for input and exit of the exhaust gas, an exhaust gas recirculation valve 20 is provided, which controls the supply of the main gas to the aspirator.
- the Exhaust gas recirculation valve 20 is arranged on the clean side of the filter element, so that contamination of this valve is prevented.
- FIG. 5 shows a cooling device for exhaust gas recirculation.
- the exhaust gas is supplied via the line 21 to the filter element 4 and flows over cleaned the Abgas Weg technologicalanschlußstutzen 22 in the Saugrohrplenum 23.
- For cooling the exhaust gas recirculation cooling water connections 24, 25 are provided.
- the cooling water flows around the filter element 4 and ensures a constant Exit temperature of the exhaust gas in the Saugrohrplenum 23.
- the with Exhaust gas mixed intake air passes through the intake flange 26 to the here not shown internal combustion engine or the internal combustion engine.
