Definitions
- the present invention relates to an exhaust gas recirculation device for an internal combustion engine comprising an exhaust passage, via which exhaust gas can be derived from the internal combustion engine, an inlet channel, via which combustion air for
- Internal combustion engine is leitbarer, and a heat exchanger, which is fluidically connectable at one end to the exhaust passage, and which is fluidically connectable at an opposite end with an exhaust gas recirculation passage, which opens into the inlet passage.
- the heat exchanger has two structurally separate strands, which open into a collector which is fluidically connected to the exhaust gas recirculation channel.
- an exhaust gas recirculation valve is arranged, via which a flow cross section of the exhaust gas recirculation passage can be regulated.
- thermal energy can be used, for example, to heat the internal combustion engine faster, to heat the cab more quickly or to reduce friction losses by heating the lubricant system.
- the thermal energy is thereby reclaimed via an exhaust gas recirculation device, which has a heat exchanger, via which a cooling of the recirculated exhaust gas takes place, so that the pollutant emissions are reduced after the cold start phase.
- WO 2014/136024 A1 discloses an exhaust gas recirculation device with a U-shaped heat exchanger, which is connected to an exhaust gas channel and in an apex region of the heat exchanger via an exhaust gas recirculation valve with an inlet channel, via the combustion air to the internal combustion engine is conductive.
- a rectangular flap valve is arranged, which between a first position in which the exhaust passage is fully opened and a mouth of the heat exchanger is completely closed and a second position, wherein the exhaust passage in the region of the heat exchanger completely closed and upstream in the flow direction strand the U-shaped heat exchanger is fully open, so that the exhaust gas flow is passed into this strand of the heat exchanger, is adjustable.
- the exhaust gas recirculation device according to the prior art has the disadvantage that a sufficiently high flow gradient in the exhaust gas recirculation channel must be present, so that the heat exchanger is flowed through with a sufficient amount of exhaust gas.
- the exhaust gas recirculation device according to the prior art is not suitable for low-pressure operation, since the resistance in the exhaust gas recirculation channel is always higher than in the exhaust gas channel. Accordingly, sufficient controllability of the recirculated exhaust gas flow is not achieved, in particular in phases with high exhaust gas recirculation rates.
- the emission levels prescribed by law can not be achieved in accordance with such an exhaust gas control device, in particular in the low pressure range.
- the object of the present invention is therefore to provide an exhaust gas recirculation device for an internal combustion engine, which is also suitable for the low-pressure operation, which has a high efficiency with respect to the recovered thermal energy, even with a high proportion of recirculated exhaust gas, and wherein the proportion of recovered from the exhaust gas thermal energy is controllable.
- the exhaust gas recirculation device has two structurally separate strands, which open into a collector.
- the two strands are thus configured in such a way that a mutual influence of the currents in the strands is avoided.
- At one end of both strands these are connected to each other via the collector, so that either the exhaust gas from both strands is passed via the collector in the exhaust gas recirculation passage, or the exhaust gas from the upstream in the exhaust gas direction first strand via the collector depending on the flap position of the exhaust gas recirculation valve is directed to the second strand.
- the exhaust gas recirculation device has a flap valve, which is arranged in the exhaust passage such that the flap valve releases the exhaust passage in a first position, closes the exhaust passage in the flow direction downstream of the two strands in a second position, so that the exhaust gas flow both strands in the direction of the exhaust gas recirculation passage flows through, and in a third position, the flap valve closes the exhaust passage in the region between the two strands, so that the exhaust gas flow through the upstream upstream in the exhaust gas direction can be conducted, and the second strand can be flowed through in the opposite direction in dependence of the position of the exhaust gas recirculation valve.
- the flap valve In the first position, the flap valve thus has a minimal flow resistance in the exhaust passage, so that the flow in the exhaust passage through the flapper valve is hardly disturbed. In the second position, however, is a complete flow through the Exhaust ducts from the flap to the downstream of the two strands prevented.
- the exhaust gas is thereby redirected with open EGR valve in both strands of the heat exchanger, so that the total amount of exhaust gas is distributed over two strands and thus the maximum heat exchanger cross section is utilized. This increases the proportion of recovered thermal energy.
- the third position a flow through the exhaust duct is prevented from the structural separation between the strands.
- the exhaust gas is thereby passed through the strand upstream in the flow direction.
- a portion of the exhaust gas is thereby recirculated to the internal combustion engine, wherein the recirculated exhaust gas is cooled only by a train, so that the cooling of the recirculated exhaust gas is reduced.
- hotter exhaust gas can be recirculated in cold operating conditions in which there is the risk of condensation of the combustion air, in order to avoid condense formation.
- the exhaust gas not recirculated in the third position is fed back into the exhaust gas duct in the downstream stream. In this case, the thermal energy is recovered from the exhaust gas in this strand.
- the proportion of the thermal energy recovered from the exhaust gas can be regulated in order to better adapt the exhaust gas recirculation device to specific operating conditions.
- the flap valve is infinitely adjustable between the three positions.
- a continuous adjustment between the positions in the sense of the present invention is when the flapper valve between the first and the second positions, as well as between the second and the third position, can take any intermediate position.
- an intermediate position between the first position and the second position is the Restricted flow in the exhaust passage, so that on this position and the position of the EGR valve, the recirculated exhaust gas quantity is regulated. Since both strands are flowed through between the first and second position, the recovered thermal energy amount increases with increasing amount of recirculated exhaust gas.
- the flap valve is a butterfly valve.
- the butterfly valve has the advantage that due to the balancing forces of the gas flow on the flap, in a static position of the valve, only low holding forces are necessary. Also, for the adjustment of the flap, only a small torque is necessary.
- the axis of rotation of the flap valve is arranged in an extension of the structural separation of the strands. In the third position, the flap valve thus extends the structural separation up to a wall of the exhaust gas passage. As a result, a symmetrical construction of the flap valve is possible.
- the axis of rotation of the flap valve is arranged centrally in the exhaust duct.
- the axis of rotation cuts an axial central axis of the exhaust duct in this area.
- the flap valve is thereby arranged symmetrically in the exhaust duct, so that the exhaust duct can be formed symmetrically in the region of the flap valve.
- the axis of rotation of the flap valve is arranged on a side opposite the strands of the exhaust passage.
- the axis of rotation is arranged such that it has the greatest radial distance from the strands. In the first position, the flow resistance of the flap valve is thereby reduced by the flap and the axis of rotation lying substantially outside the main flow.
- the flap preferably a rectangular flap and the exhaust duct in the region of the flap valve rectangular shaped.
- a flap end remote from the axis of rotation is arranged in the second and third position directly opposite an exhaust gas duct wall or the structural separation between the strands.
- the flap end is arranged such that a distance between the flap end and exhaust duct wall or the physical separation is minimal, so that only a leakage flow between the flap end and exhaust duct wall or the structural separation is present. This allows the flow in one direction to be completely stopped and redirected in another direction.
- the exhaust gas recirculation device is a low pressure exhaust gas recirculation device. Due to the possibility of parallel flow through both strands, the operation of the heat exchanger is given even at low back pressure as it exists in a low pressure exhaust gas recirculation device.
- the exhaust passage is spherical in the region of the flap valve, wherein a diameter of the spherical shape is larger than an exhaust duct diameter.
- a contact surface can be provided for the flap so that a flow in the exhaust duct can be prevented. This contact surface is provided by the larger diameter outside the main flow, so that the main flow in the exhaust duct is not disturbed by the contact surface.
- the flap in particular in the second position, close the exhaust gas channel and redirect the exhaust gas flow into the strands, without a flap end projecting into the opening cross-section of the strand downstream in the flow direction.
- such a formation simplifies the manufacture of the channel housing.
- the structural separation between the strands of the heat exchanger is preferably a partition wall.
- the partition wall forms a boundary wall of each strand of the heat exchanger.
- an exhaust gas recirculation device for an internal combustion engine which has a high efficiency in terms of the recovered thermal energy even with a high proportion of recirculated exhaust gas.
- Figure 1 Schematic representation of an inventive
- FIG. 2 exhaust gas recirculation device according to FIG. 1 with the EGR valve open;
- FIG. 5 exhaust gas recirculation device according to Figure 4 with the EGR valve open
- Embodiment in a second position with open AG R valve.
- Exhaust gas recirculation device 10 includes an exhaust passage 14 that discharges exhaust gas 18 from the internal combustion engine to the environment, and an intake passage 22 that conducts combustion air 26 to the internal combustion engine.
- the exhaust gas recirculation device 10 additionally comprises a heat exchanger 30 which is fluidically connected at one end to the exhaust gas channel 14 and at an end opposite thereto to an exhaust gas recirculation channel 34 opening into the inlet channel 22.
- the heat exchanger 30 has two strands 42, 44 which are separated by a partition wall as structural separation 38 and which are combined in front of the exhaust gas recirculation duct 34 in a collector 46, which is connected directly to the exhaust gas recirculation duct 34.
- an exhaust gas recirculation (EGR) valve 50 is arranged, which is continuously variable between a position in which the exhaust gas recirculation passage 34 is closed and a position at which the exhaust gas recirculation passage 34 is fully opened.
- the EGR valve 50 shown in Figure 1 is shown in a closed position.
- the exhaust passage 14 designed as a butterfly valve flap valve 54 is arranged.
- the exhaust duct 14 is spherical, wherein a diameter D K of the spherical shape is greater than an exhaust duct diameter D A and greater than a width B of both strands 42, 44 of the heat exchanger 30.
- a rotation axis 58 of the butterfly valve 54 is centered in the exhaust duct 14th in an extension of the partition wall 38 of the two strands 42, 44 are arranged.
- the butterfly valve 54 shown in Figure 1 is shown in a first position in which the exhaust passage 14 is fully opened. However, the butterfly valve 54 may also assume intermediate positions between the first and second positions shown in FIG. In the first position, the butterfly valve 54 extends substantially in a flow direction of the exhaust passage 14. In the illustrated position of the butterfly valve 54 and the EGR valve 50, no flow is generated in the heat exchanger 30.
- the exhaust gas recirculation device 10 in Figure 2 differs from the exhaust gas recirculation device 10 of Figure 1 in that in the exhaust gas recirculation device 10 in Figure 2, the EGR valve 50 is open. As a result, part of the exhaust gas 18 is returned to the internal combustion engine. This recirculated exhaust gas causes a flow in the heat exchanger 30, so that the heat from the recirculated exhaust gas can be recovered. Since both strands 42, 44 are open to the exhaust passage 14 in the position shown in Figure 2, the heat exchanger 30 is flowed through both strands 42, 44 of the recirculated exhaust gas, so that the effective cross-section of the heat exchanger 30 is increased and thereby the proportion of recovered thermal energy is increased.
- the exhaust gas recirculation device 10 is shown in a second position of the butterfly valve 54 when the EGR valve 50 is open.
- the butterfly valve 54 can also intermediate positions between occupy the second and the third position shown in Figure 4.
- flap ends of the butterfly valve 54 remote from the axis of rotation 58 are disposed directly opposite an exhaust duct wall 62.
- the butterfly valve 54 closes the exhaust passage 14 in the flow direction downstream of the two strands 42, 44.
- the entire exhaust gas flow of the exhaust passage 14 is thereby returned and flows through both strands 42, 44 of the heat exchanger 30 in the direction of the exhaust gas recirculation passage 34.
- the exhaust gas recirculation device 10 is shown in a third position of the butterfly valve 54 with the EGR valve 50 closed.
- flap ends of the butterfly valve 54 remote from the axis of rotation 58 are arranged directly opposite the dividing wall 38 or the exhaust duct wall 62, the butterfly valve 54 closing the exhaust duct 14 in the region between the two strands 42, 44, so that the exhaust gas flow through the upstream in the exhaust gas direction first strand 44 is passed.
- the collector 46 which connects the two strands 42, 44 with each other, the exhaust gas 18 is directed in the opposite direction to the first strand 44 via the second strand 42 back into the exhaust passage 14.
- the entire length of the heat exchanger 30 can be flowed through.
- the exhaust gas recirculation device 10 in FIG. 5 differs from the exhaust gas recirculation device 10 according to FIG. 4 in that in the exhaust gas recirculation device 10 in FIG. 5 the EGR valve 50 is open. As a result, depending on the position of the EGR valve 50, part of the exhaust gas 18 is returned to the internal combustion engine. The recirculated to the internal combustion engine exhaust gas content is doing cooled only via the upstream in the exhaust gas direction of the exhaust duct 14 first strand 44, while the non-recirculated exhaust gas fraction is returned via the second strand 42 to the exhaust duct 14 cooled. As a result, hotter exhaust gas 18 is directed into the inlet channel, which reduces the risk of condensation in cold operating conditions.
- FIG. 6 shows a second exemplary embodiment of the exhaust gas recirculation device 10, which is shown by way of example in a second position when the EGR valve 50 is open.
- the axis of rotation 58 of the flapper valve 54 is disposed on a side 42 of the strands 42, 44 of the exhaust duct 14.
- the positions of the butterfly valve 54 and the EGR valve 50 described with reference to FIGS. 1 to 5 are also possible for the second exemplary embodiment. This results in the same way for the second embodiment, the same features previously described for the first embodiment.
- the described exhaust gas recirculation device according to the invention is thus suitable for the low pressure range and thus has a high efficiency with respect to the recovered thermal energy. In addition, a controllability of the recovered thermal energy is given.
