VAZ 2110 adsorber diagram
In a car, the adsorber absorbs fuel vapor from the gas tank ventilation system and supplies it to the intake, because according to environmental standards, the gas tank must be isolated from the atmosphere.
From Wikipedia ;
Adsorber (from Latin ad - on, with and sorbeo - absorb) is a device for absorbing (thickening) a surface layer of a solid, called an adsorbent (absorber), of dissolved or gaseous substances, not accompanied by a chemical reaction. The adsorber is used in chemical, oil refining and other industries. The process occurring inside this apparatus is called adsorption.
Now the first question is - why filter gasoline vapors if they still go into the intake? The answer is simple - adjusting the internal combustion engine control program by adding the nth number of clean air at the inlet is much easier than making adjustments based on the fuel-air mixture (gasoline vapor from the tank) of an unknown proportion.
And now the answer to the main question - why delete it? So, although some manufacturers claim that this device will have enough resources for the entire life of the car, we know that they are lying)
In general, over time, the adsorber becomes clogged and stops passing air. As a result, we get excess pressure in the tank, which interferes with the normal operation of the fuel pump. In the cabin (sometimes under the hood) we get a periodic smell of gasoline, the vapors of which are squeezed out of the ventilation tube. And the engine starts running on a rich mixture due to lack of air.
Now guess how our country solves this problem? That's right, most people simply throw out the adsorber and turn off the system as shown in the diagram:
A fuel filter from a carburetor classic is usually placed on the tube from the gas tank, and the solenoid valve, through which clean air should flow into the engine, is simply shut off with a bolt.
In the picture I already wrote that this is wrong and here’s why. This method of removing the adsorber only partially solves the problem. Yes, the smell of gasoline disappears, the tank is ventilated, but no air is supplied to the intake and the engine continues to run on a rich mixture.
And now the following diagram:
Well, now a couple of visual photos of what it all really looks like:
Everything is clear here, one tube goes to the gas tank, the second through the valve to the engine.
Dear friends, today we will find out why an adsorber is installed on a VAZ, what an adsorber valve is, how this whole system works and why it is needed in general. Let's start with the fact that the adsorber is primarily needed not only so that your car complies with Euro 2, 3, etc. standards. but also so that your cabin does not smell of gasoline and there is no excess pressure in the tank. Many owners of cars of the tenth family are confused by the size of the adsorber on the VAZ, they say it takes up too much space and why is it needed at all. And he is needed. If you want to free up space, install an adsorber from Priora on a VAZ-2110 and sleep peacefully, install signals from KamAZ trucks, additional washer reservoirs in the freed-up space, or just admire it
