5.15.1. Features of the device
The catching system паров fuels prevents food leaving the system in the atmosphere паров the fuels, adversely influencing environment ecology.
In system the absorption method паров is applied by a coal adsorber. It is established in a niche of the right forward wheel 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 control unit signals the engine switches working hours of system is located.
Pairs of fuel from a fuel tank are constantly taken away on the pipeline and collect in an adsorber filled with absorbent carbon (adsorbent). At operation of the engine there is a regeneration (restoration) of adsorbent by an adsorber purge by the fresh air arriving in system under the influence of depression, transferred on the pipeline from a diffuzor of throttle knot in an adsorber cavity when opening the valve of a purge. The controler regulates degree of a purge of an adsorber depending on power setting, giving on the valve a signal with changeable frequency of an impulse.
Pairs of fuel from an adsorber on a steam line arrive in the inlet pipeline of the engine and burn down in cylinders. Malfunctions of system of catching паров fuels involve instability of idling, the engine stop, the increased toxicity of the fulfilled gases and deterioration of road performance of the car.
