System of catching of fuel evaporations (EVAP) – the general information, check of a state 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 lines of communication connecting it to the fuel tank of the car. Also the sensor of temperature of cooling liquid (EST), the vacuum valve switch (VSV) and the module of management (ESM) were a part of system. On models of the last years of release the structure of system switched in addition on the sensor of pressure of fuel evaporations installed on a back partition of a motive compartment. The scheme of an arrangement of components is submitted on an illustration. The sensor of pressure monitors the changes of pressure in system connected with development of leaks. The fuel tank, all vacuum lines brought to an adsorber and the case of a throttle are among the components which are subject to monitoring. EVAP is a part of system of onboard diagnostics of OBD-II (see the Sections System of Onboard Diagnostics (OBD) - the principle of functioning and codes of malfunctions and Information sensors - the general information and check of serviceability of functioning) and check of serviceability of its functioning on models of the last years of release, respectively, requires the special scanner.
During the parking of the car fuel evaporations are taken away from cavities of a gasoline tank and the case of a throttle in a coal adsorber where accumulate till engine launch. When the engine begins to rotate, the adsorber is blown and its contents are removed in the inlet pipeline from where comes to combustion chambers.
The coal adsorber is equipped with the control valve which design two balls enter. Depending on the current service conditions of the engine and pressure in the fuel tank the valve opens and closed, regulating process of removal of vapors of fuel of a tank and the case of a throttle.
Violation of stability of turns of idling, decrease in efficiency of return of the engine, spontaneous stops of the last can be caused by failure of the control valve, damage of a coal adsorber or connecting hoses of the EVAP system, and also the wrong laying of the last. Check also a condition of a cover of a jellied mouth of the fuel tank.
Obvious losses of fuel, as well as emergence of its strong smell during the parking can be caused by leakages of fuel-supply lines, or damage of the case of a coal adsorber, malfunction of the control valve, a detachment, or violation of passability of vaporizing lines, and also the wrong laying of the last.
