    摘要： An SCR after-treatment system for a locomotive engine includes an enclosure defining an exhaust flow path from an inlet to an outlet, the inlet being flexibly connected to an exhaust outlet of the engine, an injector located in the inlet and configured to provide an aerosolized reductant into the exhaust flow path, a mixing tube extending from the inlet into the enclosure towards a back wall of the enclosure; a plurality of catalyst cells extending parallel to the mixing tube; the exhaust flow path traveling through the plurality of catalyst cells between the mixing tube and the outlet, and a side channel located between the mixing tube and the plurality of catalyst cells. The enclosure is configured to create low back pressure and an even distribution of the exhaust flow path across the plurality of catalyst cells.

    摘要： In a method for heating an operating agent for a rail vehicle, particularly for heating a reducing agent for the after-treatment of exhaust gas, a coolant liquid is pumped through a cooling circuit of the internal combustion engine by a pump when an operating agent heating system is in an operating mode. In the operating mode, the coolant liquid is pumpable through a main heating circuit by of the pump in order to heat the operating agent in a reservoir. When the operating agent heating system is in a preheating mode, the main heating circuit is divided into two sub-circuits of a preheating circuit, the flow being able to pass through both of the sub-circuits.

    摘要： An energy recovery system for a power system is disclosed. The power system includes an engine, a generator driven by the engine, an electrical bus configured to receive electrical power from the generator, an exhaust conduit configured to receive exhaust gases from the engine, and a turbocharger coupled to the exhaust conduit. The energy recovery system includes a bypass conduit, a turbo-generator, and a synchronizer. The bypass conduit is coupled to the exhaust conduit, and facilitates a portion of exhaust gases from the exhaust conduit to bypass the turbocharger. The turbo-generator is coupled to the bypass conduit, and is driven by the portion of exhaust gases bypassing the turbocharger. Further, the synchronizer modulates one or more parameters of electrical power received from the turbo-generator based on one or more parameters of electrical power present on the electrical bus. The synchronizer transmits modulated electrical power to the electrical bus.
