There is a smell of gasoline in the car for various reasons, mainly due to a malfunction of the fuel system. To eliminate a sharp odor, it is necessary to prevent fuel leakage. This is especially important because the fault can lead to a fire.
is not valid.
All elements of the fuel system of the machine are located along the length of the body - it was conceived specifically for safety. The fuel tank is placed away from the engine, at the rear of the car, to reduce the risk of explosion.
There are, of course, also disadvantages to such a fuel system: the gas pipeline is very long and uses a lot of connections and wiring. Most often, fuel leakage occurs exactly where it is stored - that is, from a gas tank or other element that is located on or near it. You need to know how to eliminate such dangerous leaks.
The main causes of odor in the cabin of the car:
- Buck
Since the main part of the fuel is stored in the tank, then the search must begin with it. Perhaps he just rubbed or rusted.
The tank can hold up to 100 liters of fuel, so the mass, when full, can be very large, resulting in a large load on the mounts. Most often, the tank is suspended to the body, and the suspension looks like a curved iron strip, which is evenly passed under the bottom of the tank.
These strips are attracted to the body by means of high-strength bolts, and, ideally, the tank should not move, but in the course of driving due to high vibration it often rubs against the body of the machine. The designers of the VAZ2110 thought about this, so they installed special rubber gaskets between the tank and the car's body, but with intensive and extreme driving these gaskets slowly wear out, and so the tank begins to move a little, which leads to wiping the tank.
Council
Periodically inspect all elements of the fuel equipment and the pipeline, as this depends on your safety.
Another tank can rust due to poor quality metal or fuel. Such, basically, occurs at old cars, and restoration is not subject. If the tank on your car has rubbed or rusted, you need to change it immediately, and for prevention - more often follow the stretch of the tank mountings.
- Tank neck
This is the second vulnerability. The neck is fixed to the tank with a special gasket and bolts, and also with the help of welding. The latter method is less reliable, because welded seams are often destroyed - the neck bolted will last longer, even when the tank will rock strongly in different directions.
Therefore, welding seams on the tank when a smell of petrol in the passenger compartment of the VAZ should be checked first.
- Throat cover
It should fit snugly against the neck, gasoline should not flow from under it, so watch for the condition of the gasket.
There is also a special valve in the lid, through which the steam of gas is discharged when the tank pressure rises( in summer).But due to the wear of the gasket, the couples will be able to freely escape into the atmosphere. Basically, in modern cars the neck of the tank is recessed into the body of the car and is closed by its lid and from above - the hatch cover, as a result, when the gasket is worn, the couples enter the salon, and not into the street.
If the gasket under the tank cap is in normal condition, then you need to continue the leak search further. If the gasket has cracked or cracked, then it is necessary to change the cover.
- The hatch cover of the petrol pump
There is another rather vulnerable place in the tank - it is the lid to which the petrol pump located in the tank is attached, this applies to modern cars, such as VAZ2114.
The cover of the gasoline pump is fixed to the tank with bolts. Under the cover is also a gasket made of rubber, which is the vulnerable part of the construction. This gasket is affected by gasoline, which quickly destroys the rubber.
Council
Experienced car owners VAZ 2109 recommend if there was a smell of gasoline in the cabin, first of all, check for leaks all the pipeline, starting from the site under the rear seats and reaching the carburetor. However, if the car smells not of gasoline itself, but of exhaust gas, then special attention should be paid to the seal of the lanterns and rear doors.
If the petrol pump was broken and the lid was removed and placed unevenly, the gasket could break or not stop fitting tightly. In this case, it does not create the necessary tightness of the connection, which is why fuel leakage occurs. A torn or worn gasket should be replaced. You need to make sure that the lid is level.
The valve of system of release of steams of gasoline from a gasoline tank. More often, on the cover of the gasoline pump, a special valve is placed to discharge petrol vapors from the gas tank. On the valve there is a branch pipe on which the hose is put - it is for this purpose that the gasoline vapor enters the adsorber reservoir. In the process of operating a motor vehicle, this rather fragile branch pipe may break, as a result, a leak may appear, and as a result, an unpleasant smell of fuel will be present in the car's interior. To get rid of this, you will have to change the valve. Such a breakdown is especially characteristic for injection vehicles, including the VAZ2107 model.
- Fuel line( clamps, nipples)
In the fuel line, elastic hoses are used in moving places, which, in the course of driving along an uneven road, can be rubbed off, and also the clamps at the joints can loosen. Because of this, gasoline will start to escape through them, which will lead to the penetration of fuel vapors into the cabin. And this is the most common reason for the smell of fuel in the car.
- Carburetor
As a result of improper adjustment of the carburetor, the fuel will overflow, and the gasoline vapor from under the hood will penetrate into the interior of the car. This does not apply to injection machines.
- Fuel filter
In the course of long-term operation, the filter can become clogged with dirt, as a result of which the pressure in the gasoline pipeline will increase and cause leaks, for example, of clamps. To prevent this from happening, you need to change the fuel filter in time.
Knowing all the flaws in the fuel system, you can quickly eliminate the causes of the smell of fuel in the cabin by simply inspecting the car.

If the smell of gasoline appears after turning on the stove( in winter), then the leakage occurs somewhere under the hood.
How to eliminate the smell of petrol in the car?
Pairs of gasoline can appear in the cabin for many reasons, but there are few effective ways to solve this problem. Below are the most common ways to get rid of this difficult problem.
- Weathering. This method of elimination is the most effective, this allows you to quickly dissipate the gasoline vapor. If the smell in the cabin appeared in the summer, then you need to open all the doors, as well as the trunk, to form a draft. To speed up this process, you can use a fan. If there was a smell of gasoline in the winter, then turn on the full power stove and open alternately the rear and front doors, in order to ventilate the cabin. Weathering will be useless if there are problems with the tank, since it needs to be changed.
- Adsorption of petrol vapors. To eliminate the smell, you can use caustic soda, activated charcoal, silica gel and natural coffee. One of these means is scattered on a stain of gasoline. After three days, the remedy can be removed, but before removing the absorbent, you need to prepare a rag and detergent to wash off the remaining gasoline. Seats and the instrument panel must be wiped with a damp cloth. If the first time you can not get rid of the smell of fuel, then you need to repeat the procedure.
- Wash the upholstery of the car. If you want to eliminate the smell of fuel yourself in the cabin, you need to add lemon juice to the washing water, as well as a spoonful of conventional baking soda. However, this method is quite laborious and does not guarantee that the odor will be eliminated.
- Car Wash. Many car owners do not always have free time, so they solve the problem with the help of car wash and dry cleaning. Specialists select special means to completely eliminate the smell of gasoline in the cabin, as well as to wash off the stains of gasoline. In addition, they can perform ozonization salon. This will take 20-30 minutes, if the smell does not disappear, then ozonization can be performed again.
Important
Before attempting to remove the smell of gasoline from the passenger compartment, it is necessary to eliminate its cause, and for this - to eliminate the breakage of the fuel system or the failure of seals on doors, headlights and other parts of the car.
For cleaning salon from gasoline stains, the site "Miss Cleanliness" advises to use high-quality detergents, and in difficult cases to contact specialists on car washes.
