5.15.1. Features of the device

The system of catching of vapors of fuel prevents leaving the system of food in the atmosphere of the vapors of fuel which are adversely influencing environment ecology.

In system the method of absorption of vapors is applied by a coal adsorber. It is established on the basis of a body on the right behind and connected by pipelines to the fuel tank and the valve of a purge.

In a motor compartment the electromagnetic valve of a purge of an adsorber which on signals of the control unit of the engine switches system operating modes is located.

Fuel vapors from the fuel tank are constantly taken away on the pipeline and collect in the adsorber filled with absorbent carbon (adsorbent). During the operation of the engine there is a regeneration (restoration) of adsorbent an adsorber purge the fresh air coming to system under the influence of the depression transferred on the pipeline from the diffuser of throttle knot to an adsorber cavity when opening the valve of a purge. The controller regulates adsorber purge degree depending on power setting, giving on the valve a signal with a changeable frequency of an impulse.

Fuel vapors from an adsorber on the pipeline come to an inlet pipe of the engine and burn down in cylinders.

Malfunctions of system of catching of vapors of fuel involve instability of idling, an engine stop, the increased toxicity of the fulfilled gases and deterioration in road performance of the car.
