1. The system serves for prevention of hit in the atmosphere of vapors of fuel and consists of the coal filter, the ventilating valve of the float-operated camera, blowing-off system, safety system, the temperature valve, the control fuel valve and a special cap of a jellied mouth of the fuel tank (3.1a, 3.1b, 3.1v and 3.1g).

Coal filter
2. When the engine does not work, fuel vapors from the fuel tank and the float-operated camera of the carburetor gather in the coal filter. During the operation of the engine they are issued in an inlet collector.

3. The ventilating valve controls intake of vapors of fuel in the coal filter. During the operation of the engine the valve is closed and when the engine is switched off, the valve is open, and vapors of fuel gather in the coal filter.
Blowing-off system
4. The blowing-off system is closed during the single operation of the engine in order that vapors of fuel did not get to an inlet collector. At increase in speed of operation of the engine, the valve of blowing-off system opens.
Temperature valve
5. The temperature valve watches temperature of cooling liquid and controls work of blowing-off system that reduces the SO i NS level in exhaust gases at warming up of the engine.
Cover of a jellied mouth of the fuel tank
6. In a cover the vacuum valve preventing emission of vapors of fuel in the atmosphere is installed.
Safety system
7. The system consists of two valves:
a) Pressure valve which opens when internal pressure in the fuel tank exceeds normal pressure.
b) The vacuum valve which opens when internal pressure in the fuel tank below normal level.
Control fuel valve
8. The valve prevents leak of fuel in case of a car revolution. Two balls are installed in the valve. When the car turns over, one of balls closes the fuel channel, preventing fuel leak.
