The message with the atmosphere of the fuel tank is carried out through an adsorber (a catcher of fuel vapors).

Vapors of gasoline are kept by absorbent carbon, contained in an adsorber. Gasoline vapors from an adsorber come to the engine where burn down. For this purpose the absorber connects to an inlet collector by means of the electromagnetic valve which is located on a mudguard cup.

The principle of operation of the electromagnetic valve consists in change of the section through passage depending on a signal of extent of the cyclic opening arriving from EBU of system of injection.

Change of the section through passage of the channel for fuel vapors in the electromagnetic valve happens due to balance between the magnetic field created by the winding supply voltage, and effort of the returnable spring providing closing of the electromagnetic valve.
