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 in a power supply system 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. The description 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 a jellied mouth of the fuel tank is equipped with the bilateral safety valve. In case of refusal systems the valve provides withdrawal of fuel evaporations in the atmosphere. Other locking valve (ORVR valve) is installed near 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. On the way to a coal adsorber fuel evaporations are missed via the double-thread valve and on ventilating hoses get to the coal adsorber established in a motive compartment where 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. The fuel tank is equipped also with the sensor monitoring changes of pressure in a tank both during the parking and on the run of the car. CHECK REPLACEMENT Coal adsorber
