Definitions
- the invention relates to a device for gas recirculation in a Internal combustion engine, in particular exhaust gas or the gas from a crankcase ventilation, according to the preamble of the main claim.
- the invention has for its object a device for recycling of exhaust gases so that there is no significant pollution more is coming.
- the task is characterized by the distinctive features of the independent Claim 1 solved.
- the inventive device of the type specified is in advantageously designed so that in a first embodiment in the connecting line between the exhaust duct and the connection a filter element is arranged in the intake device of the internal combustion engine is. According to a second embodiment, is also more advantageous Way in the connecting line between the connection of a crankcase ventilation and the connection to the suction device of the Internal combustion engine arranged a filter element.
- Filter medium may preferably be a high temperature resistant medium, e.g. on Stainless steel compact, can be provided.
- the filter element could be heavily contaminated when it is to be monitored anyway Air filter change interval can also be changed.
- the filter element can be designed as an inline filter according to an advantageous embodiment or for reasons of assembly also in the exhaust gas recirculation flange of the suction pipe can be integrated.
- a cyclone can 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 to be used and no additional filter is to be provided. In this case it is advisable to use a multi-cell cyclone, which has a high Has separation performance.
- a further advantageous embodiment of the invention can be seen in that cleaning is done by electrical energy. Periodically becomes the filter medium by applying an electrical voltage heated to above the burning temperature of the soot and the soot burned.
- the Combustion gases can enter the exhaust duct via a corresponding line be fed to the internal combustion engine.
- Another alternative to switching the filter element is available through an electrostatic precipitator. This has a very high separation performance and a low ⁇ p. Even the electrostatic separator can be cleaned by heating.
- a further development of the invention is the use of an easy-change filter for the filter element. So that the exchange of the filter element within a certain maintenance cycle can easily be done is the filter element arranged in a removable filter.
- This easy-change filter is similar to a spin-on oil filter and can be easily used, for example dispose of thermally.
- Embodiments of the device for exhaust gas recirculation according to the invention in an internal combustion engine is based on the following figures explained.
- Figure 1 is a section through a device 1 for cooling exhaust gas with an exhaust gas recirculation 2 for an internal combustion engine, not shown here shown.
- the exhaust gas flows through in the recirculation 3 according to the arrow a filter element 4 to a connecting flange 5 on the not shown here Intake device 6 of the internal combustion engine.
- the returned gas is freed of soot by the filter element 4 and only the cleaned hot exhaust gas to the internal combustion engine or the Intake pipe supplied.
- the filter element 4 has here as a filter medium high temperature resistant material, namely a stainless steel compact on and is designed as an inline filter.
- the filter element also in the exhaust gas recirculation flange Suction pipe to be 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 suction device 6 arranged.
- Sleeve 8 and exhaust gas recirculation pipe is another in the outlet area of the pipe thermally coupled from the exhaust gas recirculation pipe 7, Sleeve 9 provided. The exiting exhaust gas flows without heating the closer ones Environment of the suction device 6 in the collector for the intake air on.
- Figure 2 shows a cleanable filter element 4, which consists of a Steel mesh 5 on which the soot particles of the exhaust gas attach.
- the steel knitted fabric 12 is cleaned with a not shown here Voltage source connected via connections 10 and 11. When putting on An electric voltage at these connections heats up the knitted steel 12 to above the ignition temperature of the deposited soot. The soot is burned off and the resulting combustion gases via a flow reversal and a flow according to arrows 13, 14 supplied to the exhaust gas of the internal combustion engine.
- FIG. 3a shows the production of the filter element 4 from, for example, one Steel fabric.
- this is a wire conductor 15 consisting of a Large number of individual wires with electrical connections 10 and 11.
- This wire conductor is inserted into the housing 16 of the filter element and closed the housing.
- the wire conductor can be easier to maintain Way be removed from the housing and a new wire conductor can be insert easily (Figure 3b).
- Figure 4a shows a schematic representation of an easy-change filter in which a steel mesh 12 is arranged.
- This easy-change filter 16 is on one Filter head 17 attached to the input 18 and output 19 for the exhaust gas is connected.
- FIG. 4b also shows a spin-on filter 16 in a schematic representation being in the filter head 17 in addition to the connections for input and an outlet of the exhaust gas, an exhaust gas recirculation valve 20 is provided, which controls the supply of the main gas to the suction device.
- the Exhaust gas recirculation valve 20 is arranged on the clean side of the filter element, so that contamination of this valve is prevented.
- Figure 5 shows a cooling device for the exhaust gas recirculation.
- the exhaust gas will via the line 21 to the filter element 4 and flows over cleaned the exhaust gas recirculation connector 22 in the intake manifold plenum 23.
- Zum Cooling the exhaust gas recirculation cooling water connections 24, 25 are provided.
- the cooling water flows around the filter element 4 and ensures one constant outlet temperature of the exhaust gas in the intake manifold plenum 23.
- Die Intake air mixed with exhaust gas passes through the intake flange 26 to the Internal combustion engine or the internal combustion engine, not shown here.
