Catching system паров fuels (EVAP) General description The EVAP system carries out adsorption паров fuels and their burning as a part of gas mixture during normal functioning of the engine. The structure of any system of catching паров fuels surely includes an adsorber filled with absorbent carbon in which collecting паров gasoline is carried out. Difference of one system from another can consist in implementation management of a conclusion of evaporations. The description of the system typical for models of brand described in this Management of cars which should supply the owner with information, sufficient for understanding of a principle of a conclusion паров fuels on its car below is provided.
The cover of a mouth of the gulf of fuel is equipped with a double-thread safety valve. The valve serves for a conclusion in the atmosphere of the evaporations which have accumulated in a fuel tank in default EVAP systems. Other cutting (unloading) valve is established on a fuel tank and serves for conclusion adjustment паров fuels from a tank in a coal adsorber depending on presence at a tank of superfluous or negative pressure (depending on ambient temperature). After passing of the double-thread valve fuel evaporations on ventilating hoses arrive in the coal adsorber located in an impellent compartment where they are adsorbed by absorbent carbon and are stored to a conclusion in chambers of combustion of the engine.
When the engine is started and warmed up to in advance established temperature the cutting electromagnetic valve of a purge near an adsorber closed, providing opening by depression of the inlet pipeline of the diafragmenny valve of management by an adsorber purge. Thus pairs of fuel are deduced from an adsorber also under the influence of depression of the inlet pipeline.
Check
Always first of all check a condition of hoses, the detachment or which damage appears an EVAP system cause of failure more often. For check of correctness of connection of hoses be verified with the scheme of laying of vacuum hoses put on шильду, fixed on a radiator support under a car cowl. In case of need make repair or replacement of the damaged hoses.
