Definitions
- the invention relates to an exhaust system of an internal combustion engine, in particular a motor vehicle, with a catalytic converter, in particular a NOx storage catalytic converter, a cooling section being provided in front of the catalytic converter, according to the preamble of claim 1.
- NOx storage catalytic converters are increasingly being used for converting nitrogen oxides in gasoline engines with direct fuel injection. Since sufficiently high conversion rates can only be achieved in relatively narrow exhaust gas temperature windows, it is necessary to match the engine operation and the catalytic converter system so that the exhaust gas temperatures at the entry into the storage catalytic converter are as far as possible within the temperature window for a large operating range.
- DE 199 05 345 A1 discloses an exhaust gas aftertreatment device for a motor vehicle for treating the exhaust gas flow of an internal combustion engine with a three-way catalytic converter and a downstream NOx trap. The exhaust gas is conducted between the three-way catalytic converter and the NOx trap via sensitive parallel paths with a temperature change path that has a continuous flow.
- the present invention is therefore based on the object of providing an exhaust gas system of the type mentioned above, in which the upper temperature limit is prevented as far as possible for the entire lean operating range of the internal combustion engine with little effort.
- This object is achieved according to the invention by an exhaust system of the type mentioned above with the features characterized in claim 1.
- Advantageous embodiments of the invention are specified in the dependent claims.
- the cooling section is of a multi-flow design in a suitable form and / or is provided with additional coolants, as a result of which, in all the respective operating phases of the internal combustion engine with different exhaust gas mass flows, there is a thermal energy output from the exhaust gas based on the thermal energy contained in the exhaust gas (relative thermal energy output) elevated.
- the additional coolants comprise ribs which are arranged on the outside of the cooling section, are distributed uniformly over the circumference and project outwards.
- the additional coolants comprise at least one exhaust gas supply line designed as a heat exchanger, which has an ovality that changes in the longitudinal direction.
- a further increase in surface area and improved turbulence formation is achieved in that the additional coolants comprise at least one exhaust gas supply line which is corrugated in the longitudinal direction.
- the additional coolants comprise at least one exhaust gas supply line with inwardly extending impressions, both an increase in the surface area of the heat transfer surface and a turbulence formation of the exhaust gas flow flowing through is achieved.
- the additional coolants comprise at least one exhaust gas supply line with internal beads, which are optionally inclined in the flow direction.
- the additional coolants comprise at least one exhaust gas supply line having an n-square, rectangular, triangular, semicircular or semi-oval cross section.
- a further increase in the heat dissipation from the exhaust gas is achieved in that the additional coolants have at least one coating arranged in the region of the cooling section, which promotes heat dissipation and / or the additional coolants comprise a device for supplying the cooling section with an outside air flow.
- 1 is a graphical representation of a relative heat dissipation and a temperature drop as a function of an exhaust gas mass flow or a vehicle speed
- 3a shows a further graphical representation of a relative heat dissipation and a temperature drop as a function of an exhaust gas mass flow
- 3b is a table of values for the graph of FIG. 3a
- FIGS. 4, 6, 8, 10 and 12. 1 shows qualitatively in curve (a) the temperature drop occurring over a conventional exhaust system as a function of the exhaust gas mass flow or the vehicle speed. This shows a typical course for the temperature reduction (dashed), which initially increases from low to medium exhaust gas mass flows and then decreases again to high exhaust gas mass flows.
- the cooling effect of the exhaust system is now optimally matched to the operating behavior of the vehicle with a direct-injection gasoline engine.
- the illustrated, multi-flow cooling section 112 (FIG. 1) comprises a plurality of exhaust gas supply lines 114. Exhaust gas flows in at 116 and exhaust gas flows out at 118.
- the area with the greatest cooling effect occurs when the exhaust gas temperature upstream of the catalytic converter 113, which is designed, for example, as a NOx storage catalytic converter, has just reached the upper temperature limit for lean operation.
- the exhaust gas temperatures are typically in a range from approx. 400 ° C to 550 ° C, which corresponds to a speed range of approx. 60 km / h to 160 km / h depending on the engine-transmission-vehicle combination (constant travel in the plane ).
- the heat dissipated via the tube walls is also plotted in relation to the total heat contained in the exhaust gas (relative heat dissipation) (solid lines 122). It is characteristic that this decreases with increasing exhaust gas mass flow (increasing driving speed) for all variants.
- FIG. 3a and 3b measured values of a preferred embodiment of an exhaust system according to the invention are shown graphically and in tabular form.
- the exhaust gas temperature drop that occurs over the cooling section 112 as a function of the exhaust gas mass flow (vehicle speed) is plotted in FIG. 3a.
- the maximum exhaust gas temperature reduction is achieved in front of the NOx storage catalytic converter 113 in the desired speed range.
- the determined course of the relative heat dissipation is also plotted.
- FIGS. 4 to 13 Various possibilities for additional coolants are shown in FIGS. 4 to 13.
- the exhaust gas supply line 12 designed as a heat exchanger 14 according to FIGS. 4 and 5 is provided with ribs 33 which are arranged on the outside, are uniformly distributed over the circumference and project outwards.
- the ribs 33 serve to increase the surface area of the heat transfer surface of the exhaust gas supply line 12 and thus to improve heat transfer to the surroundings.
- FIGS. 6, 7 show an exhaust gas supply line 12 designed as a heat exchanger 14, which has an ovality that changes in the longitudinal direction. This leads both to an increase in surface area and to turbulence formation of the exhaust gas stream flowing through the exhaust gas supply line 12.
- Figures 8, 9 one in Wavy exhaust gas supply line 12 shown in the longitudinal direction.
- FIGS. 10, 11 show an increase in surface area and turbulence formation of the exhaust gas flow in the exhaust gas feed line 12 which is circumferentially provided with indentations 34 which extend inwards, as a result of which both an increase in the surface area of the heat transfer surface and turbulence formation of the exhaust gas stream flowing through is obtained.
- Figures 12, 13 show an exhaust gas supply line 12 which is provided with beads 35 on the inside, the beads 35 also being able to be inclined in the direction of flow. The beads 35 serve to create turbulence in the exhaust gas flow in the exhaust gas supply line 12 and at the same time enable the surface area of the heat transfer surface of the exhaust gas supply line 12 to be enlarged.
- the exhaust gas supply lines 12 designed as heat exchangers 14 for increasing the turbulence in cross section can also be designed as n-angular, rectangular, triangular, semicircular or semi-oval tubes.
- the turbulence generation in the exhaust gas supply lines 12 designed as a heat exchanger 14 serves in particular to increase the heat transfer from the hot exhaust gas to the outer wall of the corresponding exhaust gas supply line 12.
- turbulence formation of the exhaust gas in the exhaust gas supply line 12 results in a temperature stratification which forms with increasing line length, that is to say the Formation of an external cold exhaust gas flow and an internal hot exhaust gas flow is prevented.
- the exhaust gas supply lines designed as heat exchangers 14 can be provided with a coating which promotes heat dissipation and / or their optionally structured outer surface can be acted upon by an outside air flow which promotes heat dissipation.
