摘要: A nozzle (1) includes a nozzle body (10), a piston (2) movably disposed inside the nozzle body (10), and a spring (3) between the nozzle body (10) and the piston (2). A reducing agent flow channel (12) extends between a nozzle inlet (11) and a nozzle orifice (14), which widens towards a nozzle opening (13). A piston head (21) closes or opens the nozzle orifice (14). The spring (3) biases the piston (2) to close the nozzle orifice (14) with the piston head (21). A largest diameter (D13) of the nozzle opening (13) is larger than a largest diameter (D21) of the piston head (21). An exhaust gas treatment device (5) includes a tank (51) for the liquid reducing agent, the nozzle (1), a reducing agent pump (53) and a reducing agent conduit (52). A control (54) is configured to operate the reducing agent pump (53) continuously with variable output.

摘要: An internal combustion engine, exhaust system, exhaust gas/reactant mixing assembly unit includes an inlet area (14) of an exhaust gas flow duct (12) and a reactant release device (20) releasing reactant (R) into exhaust gas (A) flowing in the exhaust gas flow duct. The exhaust gas flow duct includes a mixing section (16) with a first mixing section segment (22) downstream of the reactant release device (20). An exhaust gas/reactant mixture flows in the first mixing section segment essentially in a main flow direction (H1)—from the reactant release device to a deflection area. A ring-shaped second mixing section segment (28) surrounds the first mixing section segment. The exhaust gas/reactant mixture flows in the second mixing section segment (28) in a second main flow direction (H2), essentially opposite the first main flow direction, from the deflection area (26) to an outlet area (34) of the exhaust gas flow duct (12).

摘要: A device for releasing reactant (R) into the exhaust gas stream (A) of an internal combustion engine, includes a reactant injection unit (20), a reactant delivery unit (12) for delivering reactant (R) from a reactant reservoir (14) to the reactant injection unit (20), and a heating unit (18) for heating reactant (R) delivered by the reactant delivery unit (12) to the reactant injection unit (20). The reactant injection unit (20) is switchable as a function of a reactant pressure generated by the reactant delivery unit (12) between an open state for releasing reactant (R) and a locked state for preventing the release of reactant.

摘要: A thermoelectric generator includes a first channel for passing a warm fluid along a direction of flow, a second channel for passing a cold fluid, a plurality of thermocouple elements disposed along the direction of flow between the first and second channels, a first member includes portions disposed between the elements and the first channel and associated with the individual elements for providing a heat coupling between the associated element and the first channel, and a second member including portions disposed between the elements and the second channel and associated with the individual elements for providing a heat coupling between the associated element and the second channel. The sum of the thermal resistances of those portions that are associated with a first element positioned upstream of a second element is bigger than the sum of the thermal resistances of those portions that are associated with the second element.
