Abstract: Method and arrangement for treatment of a gas-flow in connection with a NOx reducing catalyst (18) that include guiding the gas-flow through an exhaust gas treatment unit (18) having several ducts (21) with exchange of heat between the ducts (21). The ducts (21) are connected to an inlet and an outlet, respectively, at the exhaust gas treatment unit (18) so that the gas-flow occurs during exchange of heat between incoming and outgoing flows. Reduction of NOx compounds in the gas-flow is accomplished by means of the NOx reducing catalyst (18). An adaptation of the temperature of the exhaust gas treatment unit (18) is affected to the prevailing operating condition of the NOx reducing catalyst (18). The method and apparatus enable provision of the required exhaust gas temperature for NOx reduction, while also accommodating the temperature limitations imposed by sulphur absorption and regeneration subsystems.

Abstract: A windshield storage device operable for mounting a detachable/removable windshield on a wall structure includes a frame structure, one or more brackets connected to the frame structure, wherein the one or more brackets are operable for attaching the frame structure to the wall structure, and one or more receiving mechanisms connected to the frame structure, wherein the one or more receiving mechanisms are operable for receiving one or more attachment mechanisms of the detachable/removable windshield. The frame structure includes an upper member, a lower member, and two side members. The one or more brackets are operable for fixedly or removably attaching the frame structure to the wall structure. The windshield storage device also optionally includes a headlight connected to the frame structure and two turn signal lights connected to the frame structure and a power supply coupled to the frame structure.
