Definitions
- the invention relates to an internal combustion engine, in particular a multi-fuel large diesel engine, with a bypassable SCR catalytic converter, with at least one control member for switching the flow in an exhaust gas line between a first position activating the SCR catalytic converter and a second bypassing the SCR catalytic converter Position, and at least one bypass the SCR catalyst flow path.
- FR 2 914 947 A1 discloses an internal combustion engine having an exhaust gas line, in which an SCR catalytic converter is arranged, wherein a bypass line which can be controlled via a control element is provided to bypass the SCR catalytic converter.
- DE 44 21 257 AI describes an internal combustion engine with two individually disengageable cylinder groups, each having its own catalytic converter.
- the respectively assigned catalytic converter cools below its operating temperature, the entire exhaust system is designed so that the ejected from the deactivated cylinder group gases are heated by the exhaust gases of the still fired cylinder group.
- a bypass flow path for bypassing the catalysts is not provided.
- the object of the invention is to avoid these disadvantages, and to avoid unacceptable contamination or even destruction of the SCR catalyst in loading modes in a simple and space-saving manner.
- the flow path bypassing the SCR catalyst is formed as an annular space between two, preferably equiaxial, concentric tubes, wherein the SCR catalyst is taken up by the inner tube, and wherein a first inflow pipe to the inner pipe and a second inflow pipe to the immediate Flow path leads.
- the inflow to the SCR catalytic converter can be activated or closed.
- an additive metering device for an aqueous urea solution is arranged in the first inflow pipe.
- a second control member may be arranged in the second inflow pipe to open or close the immediate flow path.
- the SCR catalytic converter In gas mode or in low-emission mode, the SCR catalytic converter is activated and deactivated in heavy oil operation.
- first compensator element 12 and the second compensator element 13 are designed as a common double compensator unit 15, wherein preferably the first and the second compensator element 12, 13 are connected to each other via radial webs 14.
- an SCR catalytic converter 1 is arranged in a housing 2, which has two tubes 3, 4 arranged concentrically with one another at a radial distance, between which an annular space 5 is clamped.
- the SCR catalyst 1 is received by the inner tube 3.
- the annular space 5 forms a flow path S 2 for bypassing the SCR catalytic converter 1.
- the inner tube 3 is connected to a first inflow pipe 6 and the outer pipe 4 is connected to a second inflow pipe 7.
- a first control member 8 formed, for example, by a switching flap is arranged to release or block the SCR catalytic converter 1 for the exhaust gas flow Si.
- a second control element 9 can be arranged in the second inflow pipe 7, which can likewise be formed by a simple switching flap (FIGS. 3, 4).
- the inflow pipes 6, 7 may be formed by arcuate or S-shaped curved conduits, the first inflow pipe 6 being guided partially within the second inflow pipe 7 (see FIGS. 2 to 4). As shown in Figure 4, the two inflow pipes 6, 7 emanate from a common exhaust pipe 11.
- Upstream of the first control member 8 is arranged a Addi ⁇ tivzumess adopted 10 in the first supply pipe 6 in order to be able to supply aqueous urea solution as a reactant the SCR catalyst.
- FIGS. 5 and 6 show alternative embodiments, wherein at least one of at least two axially spaced regions of the inner tube 3 or of the outer tube 4 and / or between the inner tube 3 and the first inflow tube 6 or between the outer tube 4 and the second inflow tube 7 a first or second compensator 12, 13 is arranged to compensate for vibrations and / or thermally induced changes in length.
- Fig. 5 shows an embodiment in which separate compensator elements 12, 13 are provided for the inner tube and the outer tube 4.
- the compensator elements 12, 13 are connected via radial webs 14 to form a double compensator unit 15.
- the Doppelkompensatorü 15 can be installed as a whole.
