  • Exhaust removal system
    Patent number: 4744305
    Abstract: A diesel exhaust hood system is disclosed in which a narrow smoke entry slot and large capacity allow bursts of exhaust gases from locomotive engines to be contained inside the hood. The likelihood of spillover from exhaust exceeding the fan capacity is reduced by the use of the inverted V-shape design of the smoke entry slot. A plurality of damping baffles positioned along the length of the hood can be adjusted independently to retain a constant slot velocity throughout the length of the hood.
