System of catching of fuel evaporations (EVAP) – the general information, check of a condition and replacement of components
On models of early years of release the EVAP system consisted of the coal adsorber equipped with the control valve and the lines of communication connecting it to a fuel tank of the car. Also into structure of system entered the sensor of temperature of cooling liquid (eats), the vacuum valve switch (VSV) and the module of management (ESM). On models of the last years of release the sensor of pressure of the fuel evaporations is switched in addition on in structure of system, established on a back partition of an impellent compartment. The scheme of an arrangement of components is presented on an illustration. The sensor of pressure traces changes of pressure in the system, connected with development of leaks. The number of components subject to monitoring includes the fuel tank, all vacuum lines brought to an adsorber and the throttle case. EVAP is a part of system of onboard diagnostics of OBD-II (see. Sections System of onboard diagnostics (OBD) - a principle of functioning and codes of malfunctions and Information sensors - the general information and check of serviceability of functioning) and for check of serviceability of its functioning on models of the last years of release, respectively, is required the special scanner.
During car parking fuel evaporations are taken away from cavities of a fuel tank and the throttle case in a coal adsorber where accumulate till engine start. When the engine starts to rotate, the adsorber is blown and its contents are deduced in the inlet pipeline, from where arrive in combustion chambers.
The coal adsorber is equipped with the control valve into which design two balls enter. Depending on the current service conditions of the engine and pressure in a fuel tank the valve opens and closed, regulating branch process паров fuels from a tank and the throttle case.
Violation of stability of turns of idling, decrease in efficiency of return of the engine, spontaneous остановы the last can be caused by failure of the control valve, damage of a coal adsorber or connecting hoses of EVAP system, and also the wrong laying of the last. Check also a condition of a cover of a jellied mouth of a fuel tank.
Obvious losses of fuel, no less than emergence of its strong smell during parking can be caused by leaks топливопроводов, or damage of the case of a coal adsorber, malfunction of the control valve, a detachment, or violation of passableness of isparitelny lines, and also the wrong laying of the last.
