FIELD: ventilation.
SUBSTANCE: method for complex cleaning of exhaust gases of automotive vehicles from harmful contaminants in closed premises, providing that a flexible stainless hose is connected with the exhaust pipe of the car to remove exhaust gases, and through the stainless adapter and through a stainless bushing to the upcast shaft, exclude the ingress of the original exhaust gases back into the flexible stainless hose due to the check valve installed in the place of attachment of the stainless bushing and the upcast shaft. The gas flow rate is increased at the outlet of the upcast shaft and the back pressure of the exhaust gases is reduced by means of a fan upcast system which is switched on from the control panel, and the breakthrough exhaust gases are removed from the car box into the atmosphere and filled with fresh air from the atmosphere by means of intake and upcast ventilation, which is switched on from the control panel. At the first stage, the exhaust gases are cleaned through the diesel particulate filter, and at the second stage, the exhaust gases are cleaned in the catalytic converter, after cleaning the exhaust gases through the upcast shaft exit into the atmosphere, then the supply and upcast ventilation and the roof fan are switched on, then the air through the intake hoses, air ducts and the upcast pipe goes out into the atmosphere. Through the air ducts with distributive nozzles, the car box is filled with fresh air from the atmosphere until the engine stops working in the car box, or until the vehicle leaves the car box.
EFFECT: improving the quality of exhaust gas cleaning of automotive vehicles.
