SYSTEM FOR REMOVAL OF EXHAUST GASES FROM VEHICLES Russian patent published in 2002 - IPC

FIELD: ventilation of premises from exhaust gases from mobile vehicles. SUBSTANCE: invention refers specifically to ventilation of tunnels from exhaust gases from vehicles with internal combustion engines, diesel locomotives, for instance. System for removal of exhaust gases from vehicles ( internal combustion engines ) has gas vent manufactured in the form of tube, at least one through longitudinal duct arranged beneath gas vent, paired elastic shutters closing through longitudinal duct from beneath, exhaust trunk with fan installed in it, shut-off device in the form of damper mounted on one side of gas vent, exhaust branch pipe of vehicle, ellipse-shaped coupling made of insulation material. Gas vent communicates with exhaust branch pipe of vehicle and with exhaust trunk and through the latter with environment, trunk is fitted with second shut-off device installed on other side of gas vent. Exhaust branch pipe of vehicle is partially placed in gas vent and coupling is mounted on exhaust branch pipe of vehicle for contact with paired elastic shutters in through longitudinal duct of gas vent. Technical result of proposed invention consists in simplified design of system for removal of exhaust gases from vehicle, in provision for simultaneous removal of exhaust gases from several exhaust branch pipes of vehicle displaced one relative another or from vehicles with various arrangement of exhaust branch pipes, in removal of exhaust gases from vehicles moving forward and backward and in possibility of automatic control over process of removal of exhaust gases from vehicles. EFFECT: improved efficiency of removal of exhaust gases from internal combustion engines mounted on various vehicles. 15 cl, 6 dwg
