Abstract:
1. A system for capturing and processing exhaust from a moving vehicle, the system comprising: an Emissions Control Unit (ECU) configured to reduce pollutants in engine exhaust flowing through the ECU; a stationary horizontal duct including a lengthwise running slot and residing along a vehicle path, the horizontal duct in fluid communication with the ECU; a bonnet for capturing exhaust from the moving vehicle; a vertical duct for placing the bonnet in fluid communication with the horizontal duct through the slot, wherein the vertical duct is adapted to translate along the horizontal duct, and is positionable to allow positioning the bonnet over an exhaust pipe of the vehicle for capturing exhaust from the moving vehicle, the ECU processing the exhaust to reduce pollutants in the exhaust before the exhaust is released to the atmosphere; a duct transport unit translating along the horizontal duct with the vertical duct and interfacing the vertical duct to the horizontal duct; and two longitudinally extending rows of side by side tiles residing in the stationary horizontal duct, the two rows of tiles opposing each other and sliding together laterally to close the lengthwise running slot, the rows of tiles comprising alternating upper tiles with overlapping edges and lower tiles with underlapping edges, wherein the cooperation of the overlapping edges with the underlapping edges close the slot, the tiles closing laterally before and after the duct transport unit for sealing the slot in front of the duct transport unit and behind the duct transport unit.
