How to eliminate the smell of gasoline in the cabin VAZ-2107 (injector): tips

VAZ-2107 - the latest classic model"Lada". "Seven" last years of release was characterized not only by the updated engine, but also by the new power supply system. VAZ-2107 - the only classic on which the injector could be put from the factory. But even after such changes, owners complain about the smell of gasoline in the cabin. At VAZ-2107 (injector), it can appear for various reasons. Not always a technical breakdown. Read more about this problem, as well as how to eliminate the smell of gasoline in the cabin at the VAZ-2107 (injector), read further in the article.

Features of the fuel system

"Seven" is an upgraded version"Sixes". The latter, in turn, like all its predecessors, differed carburetor power system. At VAZ-2107, an injector can be used to supply the combustible mixture.

This system is more reliable andeffective work. The use of an injector power system at the VAZ-2107 allowed an increase in power by 5 percent and a decrease in fuel consumption by 7 percent.

Injection system is a whole complex of parts, combining the following elements:

• Control block.
• Sensors (mass air flow and lambda probe).
• Regulator idling.
• Fuel tank with adsorber valve.
• Pump.
• Filter.
• Nozzles
• Connecting tubes and hoses, as well as wiring.

A more detailed diagram of the fuel system of the VAZ-2107 (injector) is presented below.

How it works?Fuel is fed to the nozzles under pressure. It is much higher than that of carburetor cars, but it is pumped not by mechanical, but by an electric pump. On the Injection Sevens, a submersible pump is installed directly into the tank. On the carburetor it is mechanical and is located in the engine compartment. Because of this, he often overheated on hot days.

The submersible pump pumps fuel out of the tank, whereit enters the intake manifold under the pressure of 3 - 3.5 atmospheres by means of pipes. Pre-gasoline undergoes a cleaning procedure. For this, a fine and coarse filter is provided (the latter is located directly in front of the pump). The amount of fuel that enters the cylinders is dosed by the injectors themselves using electronics. Excess gasoline flows through the fuel check valve to the tank. This element is two-way. He is marked with the number 10 on the diagram of the fuel system of the VAZ-2107 (injector), which is presented above.

All processes for the supply and preparation of the mixturegasoline occur automatically. According to reviews, the system is quite reliable and does not require adjustments, as is the case with the carburetor. But sometimes it can cause problems. For example, the smell of gasoline suddenly appears in the cabin of the VAZ-2107 (injector). What to do and why it is dangerous, consider next.

What are the consequences

In the cabin of a working car should not beforeign odors, including fuel. If it smells of gasoline inside, it means there is a leak in the system. This is the direct cause of unauthorized fire, which is very dangerous.

It is also worth remembering that gasoline vapors are verypoisonous to the human body. The driver and passengers will feel dizzy, lethargic, and even nauseous. Therefore, do not hesitate to solve this problem.

Check tank cover

It's not about the filler neck.Even when it is opened, the smell of gasoline will not seep into the cabin. The reason must be sought in the tank itself. The injector "Sevens" it has a slightly different design. If on carburetor machines it is one-piece, then it has a hole for the pump. The lid is bolted evenly around the perimeter. Perhaps due to the weakened mounts couples begin to leak out.

Where is the tank?

On most passenger cars it is locatedunder the rear seat cushion. But on the classic "Zhiguli" it is located on the right side in the trunk (VAZ-2107 is no exception). It is easy to find it - this element is not hidden by any casing or covering.

Therefore, it can be checked for tightness,without taking off the car. The trunk of the VAZ-2107 is very small: on one side there is a tank, on the other - a spare wheel. But consider other reasons for the smell of gasoline in the cabin VAZ-2107 (injector).

Gasket

As mentioned earlier, on such carsUsed submersible pump. To seal the opening in the tank, the manufacturer used a rubber gasket. Because of it, there is the smell of gasoline in the cabin of the VAZ-2107 (injector). The reasons are very commonplace - the gasket may shrink or crack over time.

How to solve a problem?

New gasket for electric fuel pump is needed.Replacing it is very easy. First you need to release the pressure in the power supply system of the injector. To do this, you must start the engine and remove the fuse responsible for the pump when the motor is running. After a couple of seconds, the car itself will stall. Next you need to open the trunk and the key 7 to unscrew in order the bolts of the submersible pump. It is a one-piece design that combines a coarse filter, gasoline level gauge, fuel lines, a skimmer and a lid.

After unscrewing all eight bolts,need to remove the pump, removing the chip wires. Be careful - when removing can get stuck fuel gauge (it is slightly bent and has a float at the end).

Next you need to work with the gasket itself.It is necessary to get and clean the place of dirt, if any. Then install a new one in the same way. Make sure that the element clearly fits through the holes in the tank studs. Then you need to put the pump back and tighten the bolts, connect the chip, the fuse and try to start the engine. The smell of gasoline in the cabin VAZ-2107 (injector) should disappear.

Helpful advice

By repairing the fuel system, you canperform coarse filter maintenance. It represents a polymer mesh and is located at the bottom of the protivootlivnogo glass. The filter can be washed in acetone or any other solvent. Then clean with a stiff brush and blow with compressed air. Well, the best option is to replace the grid with a new one. The only problem is that it is often sold only assembled with a pump, and it costs about a thousand rubles.

Fuel lines

If the problem is not gone, and you still smellgasoline in the cabin VAZ-2107 (injector) with the windows open, you should check the tightness of the fuel lines. They stretch along the whole body. Leaks can occur anywhere. Usually the cause is mechanical damage (for example, after overcoming a high obstacle, the machine hooked the bottom of the ground). Gasoline will not always whip the river out of the car. Fuel pipes are very reliable, and often everything is limited to only small stains. But precisely because of them arises on the VAZ-2107 (injector) the smell of gasoline in the cabin.

It is worth examining the bottom more closely.If the tubes have dark drips, it means that a depressurization has occurred. Such elements need to be urgently changed. Pay special attention to places where the hoses are in contact with other objects. During operation, they can simply grind.

Adsorber valve

This element is installed on all injectors.car, and "Seven" is no exception. What is this item? An adsorber valve is a kind of canister installed in the engine compartment near the air filter and filled with activated carbon. What is it for? The adsorber valve on the "Seven" is used for condensation and absorption of gasoline vapors. The vapor of the fuel evaporates into liquid again and is sent back to the engine's power system.

How to check this item?The main symptom of a malfunction is the accumulation of gasoline vapor and a pungent smell in the cabin. Also, the problem is accompanied by failures at idle and loss of power during acceleration. If the tank hisses when opening, it means that the valve of the adsorber has become unusable. It is not necessary to change the entire jar - just one valve is enough. After the replacement, the machine works again, and sharp odors no longer penetrate the interior.

Valve check with multimeter

Также диагностику можно произвести вольтметром.How to check the fuel adsorber check valve? You need to open the hood and detach the harness piece from the valve. Next, connect the minus probe of the multimeter to ground and turn on the ignition. Then bring the positive probe to the wire chip and look at the device values. Indications should not be below 12 V.

To inspect the valve itself should be loosened.tighten the hose clamp with a screwdriver and lift the tube out. Next you need to remove the valve itself, prying it with a slotted screwdriver. It is necessary to turn on the ignition and submit “plus” and “minus” to the corresponding conclusions on the element. If the valve is working, you will hear a characteristic click. Otherwise, the item is defective and should be replaced. The cost of the new element is 350 - 370 rubles (suitable from the VAZ of the tenth family).

To replace the valve will need only splinedscrewdriver. She needs to unscrew the petrol hose clamps and pry the edges of the element. New must be installed tightly into the grooves until it clicks. Next, put the hoses on the valve and tighten the clamps. On this replacement valve adsorber "Seven" successfully completed.

Can the tank be damaged?

Unlike other cars, where the tank is underseat, the risk of damage to the "Zhiguli" increases significantly. After all, it is not protected by anything extra. This can also cause leaks and unpleasant odors in the cabin, which comes from the trunk.

Therefore, when transporting large loads you needto ensure maximum safety of the tank (although in most cases it is simply wrinkled). In the event of a breakdown, this element is not repaired and changes entirely. The use of sealant or cold welding cannot ensure complete safety.

Conclusion

So, the article discusses the reasons forthere is an unpleasant smell of gasoline in the cabin on the classic "Zhiguli". As you can see, it is quite possible to repair the VAZ-2107 (injector) with your own hands. The tank is not hidden under the seat, so it’s really possible to replace any part in a matter of minutes.
