System of catching of fuel evaporations (EVAP) – the general information, check of a state and replacement of components General information The system accumulates the fuel evaporations accumulating during the parking of the car and provides a conclusion them in the inlet pipeline for burning in the course of normal functioning of the engine. The special adsorber filled with absorbent carbon which, actually, and collects in itself(himself) fuel evaporations surely is a part of any EVAP system. The way of a conclusion of evaporations from an adsorber can vary depending on a design of concrete system. Given below will allow the reader to understand the principles of functioning of the EVAP system of any type rather in details.
The cover of the fuel filter is equipped with the bilateral safety valve. In case of refusal systems the valve provides withdrawal of fuel evaporations in the atmosphere. Other dvukhkhodovy locking valve is installed on the fuel tank and provides adjustment of withdrawal of fuel evaporations in a coal adsorber depending on the differences of pressure/depression connected with change of temperature. After passing of the double-thread valve fuel evaporations on ventilating hoses get to a coal adsorber in which accumulate during the whole time of the parking. At start of the engine until its warming up up to the certain temperature the locking electromagnetic valve of a purge of an adsorber remains closed, allowing opening of the diaphragm valve of a purge due to increase in depth of depression in the inlet pipeline. From an adsorber fuel evaporations via the diaphragm valve are blown in the inlet pipeline from where come to combustion chambers where are burned out in the course of normal functioning of the engine.
