5.15.1. Features of the device

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

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

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

Steams of fuel from a fuel tank are constantly taken away on the pipeline and collect in the adsorber filled with activated coal (адсорбентом). At engine work there is a regeneration (restoration) адсорбента an adsorber purge the fresh air arriving in system under the influence of depression, transferred on the pipeline from диффузора throttle knot in an adsorber cavity at opening of the valve of a purge. The controller regulates degree of a purge of an adsorber depending on power setting, giving on the valve a signal with changeable frequency of an impulse.

Steams of fuel from an adsorber on the pipeline arrive in an inlet pipe of the engine and burn down in cylinders.

Malfunctions of system of catching of steams of fuel involve instability of idling, the engine stop, the raised toxicity of the fulfilled gases and deterioration of road performance of the car.
