What s wrong with the smell of gasoline in the car

What's wrong with the smell of gasoline in the car

1. There is leakage at the gasoline pipe interface

Leaks may occur at the joints of the gasoline pipes, causing the smell of gasoline to enter the vehicle through the air conditioning system. If the owner notices the smell of gasoline in the car, he should check the interface of the gasoline line - open the engine compartment cover, it is easy to tell whether the gasoline pipe interface is leaking, because a layer of sludge will appear on the surface after a period of leakage. If the gasoline pipe interface is found to be leaking, the connection should be tightened or repaired.

2. The sealing ring of the round cover of the gasoline pump in the trunk or under the rear seat is damaged.

3. The gasoline oil pipe in the engine compartment is ruptured

It is easy to find by visual inspection, and if the gasoline pipe under the car is ruptured, it is easy to observe whether there is gasoline underground.

In addition, when there is a smell of gasoline in the car, the engine does not burn sufficiently, which may be due to poor spark plugs, fuel tanks, oil pipes, or leakage of gasoline.

4. Aging of rubber pipes

The rubber hose in the engine compartment will deteriorate over time, and older vehicles are prone to this problem. Once it ages, there is a risk that gasoline can leak into the engine compartment. The air conditioning system then allows the smell of gasoline to enter the car.

Therefore, once the rubber hose is aged, it needs to be replaced in time!

5. The gasoline pump has been disassembled and installed in the car

Owners who have recently replaced or disassembled a gasoline pump, do not panic if there is a gasoline smell in the car, it is likely that the residue has not been cleaned up after disassembly. This is less likely to happen, and the typical replacement interval for a gasoline pump is 100,000 km. However, the gasoline filter element is connected to the gasoline pump, and its replacement cycle is shorter, and the gasoline pump needs to be disassembled and assembled when replacing.

In this case, just check that the petrol pump is installed correctly and clean up the perimeter.

6. The gasoline is overfilled

Sometimes the owner of the car refuels the gasoline too full, although the fuel filler does not leak, the gasoline enters the carbon tank along the pipeline, and the carbon tank is released together with the gasoline when the steam is released, if the air conditioner is in the external circulation state at this time, the car may smell the smell of gasoline.

Solution: As long as the gasoline in the canister is consumed, the excess gasoline vapor in the canister will enter the cylinder for combustion through the action of negative pressure of the engine, and there will be no more gasoline vapor overflow.

7. It is transmitted from the outside into the car

It's rare, but it's not impossible.

Countermeasures: The air conditioner uses the internal circulation mode and opens the sunroof to exhaust the air.

What to do if you smell gasoline in your car

1. Pull over to the side of the road immediately

Don't panic at this time, find a roadside and park your car first.

2. Get out of the car and look for the gasoline smell

There are two steps here:

If it is only a pure gasoline smell, then the possibility of fire is not very large, but if it is mixed with a pungent rubber smell, there may have been signs of fire, and it is really on fire to extinguish the fire as soon as possible, and call the fire alarm **.

If there is no other smell, open the hood for specific inspection, and pay attention to personal safety at this time.

In your case, it is recommended to go back to the store first and let them check it for you, and see if the problem is dealt with in time.

After filling up the gas, the smell of gasoline in the car is particularly strong, what is going on?

Now the car oil circuit is very tightly sealed, and the reliability of the oil supply pipeline is also very good, so the probability of low probability is not to mention, the weakest link that can emit the smell of gasoline is the two interfaces on the carbon canister, one is the breathing interface of the carbon canister, and the other is the desorption interface (the outlet interface on the figure below).

If you can always smell gasoline that has not been burned while driving, you must stop and check the location and severity of the oil leak before you go on the road. After a long period of use, the oil pipeline may deteriorate and crack, and the fuel may leak out of these parts if there is a slight bump or a change in the pressure in the pipeline.

Sometimes the owner refuels the gasoline too full, although the fuel filler does not leak, but the gasoline enters the carbon tank along the pipeline, and the result is that the carbon tank is released when the steam is released, and if the air conditioner is in the external circulation state at this time, the car can smell the gasoline.

As long as the gasoline in the canister is consumed, the excess gasoline vapor in the canister enters the cylinder through the action of negative pressure of the engine for combustion, and there will be no more gasoline vapor overflowing, and then open the window to ventilate.

Sometimes there is a leak at the interface of the gasoline pipe, and then the smell of gasoline can enter the car through the air conditioning system. If you notice the smell of gasoline in the car, check the connection of the gasoline line. It is easy to see by opening the bonnet.

My car is now experiencing such a problem, and it slowly smells of gasoline at the beginning of the day, and I didn't think it was too bad at first, but after two days, it became even more powerful. Lift the car to see, how can you not find is **, after the inspection in the 4S shop, found that it is the oil pump, the oil nozzle is bubbling oil, in a careful look is the oil pump nozzle listed a little small seam, the oil is out of there.

Hey, it's annoying, it smells of gasoline all over the car right now.

There are many reasons for the smell of gasoline in the car, the fuel supply pipeline is damaged, or the gasoline filter is faulty, some cars are equipped with carbon canisters, whether they have not been replaced for a long time, and the working condition of the engine will also make the car smell of gasoline, if a cylinder failure does not work or the combustion is not sufficient, there will also be a great smell of raw gasoline, the air in the car begins to circulate after the air conditioner is turned on, and part of the gasoline smell is filtered by the air conditioner, or circulated to the outside of the car.

Reasons for the smell of gasoline in the car:

1. The fuel tank cap is not well sealed, and it needs to be replaced or the butter is 1 mm thick under the leather pad;

2. There are slight cracks or damages in the oil supply pipeline;

3. There is a gap between the oil pipe and the fuel tank, and if the clamp is not tight, it will cause a smell 4. The carbon tank is full of gasoline, etc.

The smell of gasoline in the car is generally caused by the following conditions:

1. The gasket in the fuel tank cap is aging or uneven (replaced).

2. The fuel injector and throttle have not been cleaned for a long time, resulting in dirt, resulting in insufficient combustion of gasoline (cleaning) 3. The gasoline filter is dirty or the connection hose interface is loose and aging (replaced) 4. The gasoline purification carbon tank is dirty or invalid (replaced).

5. The connecting hose of the fuel tank is aging and loose (replaced).

6. The sealing performance of the car is not good (repaired).

With the above reasons solved, your car should no longer smell of gas.

Insufficient combustion may be due to poor spark plugs, and there are also many fuel tanks and oil pipes leaking gasoline.

There are several possible scenarios for the smell of gasoline in the car:

1. The fuel tank cap is not well sealed, and it needs to be replaced or the butter is 1 mm thick under the leather pad;

2. There are slight cracks or damages in the oil supply pipeline;

3. There is a gap between the oil pipe and the oil tank (the clamp is not tight).

4. The canister is full of gasoline (absorbed) In addition, you should also check the pipe of the steam intake filter in the hood, the pipe of the evolution oil device (similar to that of the EFI car), and the rubber tube, which is easy to break over time.

It is recommended to go to the auto parts city to buy a high-pressure oil hose of one or two meters and throw it in the trunk for backup.

Solution: I believe that car owners know the gasoline filling hole. Next to the gasoline filling hole, there is a gasoline oil gas vent, which is used to evaporate gasoline into oil and gas when the temperature of the car's fuel tank rises.

The function of the vent is to keep the pressure in the fuel tank greater than the atmospheric pressure to prevent the engine from stalling.

When this vent is blocked, the evaporated oil and gas will be released elsewhere because it cannot be released, and the smell of gasoline will appear in the cab.

Therefore, when there is a smell of gasoline in the car, you can use compressed air to blow towards the vents.

If the vent is open, you should be able to hear the sound of air coming out of the gasoline filler.

Sometimes the smell of gasoline in the car is caused by a ruptured fuel pipe and a poor closure of the fuel tank cap. Nozzle leakage, incomplete engine combustion, etc.

3 points are more common1, the fuel tank sensor located under the rear seat cushion is not tightly sealed, resulting in gasoline overflow when the vehicle is bumpy. 2. There is a leak in the oil circuit from the fuel tank to the gasoline pump in the engine room. 3. Oil leakage at the position of the gasoline nozzle.

Hello, if there is a smell of gasoline in the car, it is usually a problem with the car's exhaust valve or an oil leak in the car's pipes.

Common causes of gasoline smell in the car:1The activated carbon tank in the engine compartment is ruptured or the pipe connected to the activated carbon tank is ruptured, and the air intake of the air conditioner is turned on just to introduce gasoline vapor into the cab, and the gasoline vapor smells most sensitive.

2.The sealing ring of the round cover of the gasoline pump in the trunk or under the rear seat is damaged. 3.

The gasoline pipe in the engine compartment is ruptured, which is easy to find by visual inspection, and if the gasoline pipe is ruptured under the car, it is easy to observe whether there is gasoline underground.

It may be that the fuel tank cap is not tightened, or it is not well sealed. Me too, check is that the fuel tank cap is not tight, now it's okay.

Mine also smells of gasoline.

Don't deal with it yet, wait for spontaneous combustion**! Admire Chang'an.

I can smell the gasoline when I finish filling up, and I can just run for a while.

There is also this phenomenon. Be sure to fix it.

The smell of gasoline in the car is very high for the following reasons:1. Fuel tank cap: The fuel tank cap is not well sealed, and it needs to be replaced or coated with 1mm thick butter under the skin.

2. Oil supply pipeline: The oil supply pipeline is slightly ruptured or damaged.

3. Joint: There is a gap between the oil pipe and the oil tank (the clamp is not tight).

4. Pipeline: The carbon canister is filled with gasoline (absorbed). Also check the air intake filter pipe in the hood, the pipe of the evolution oil pump (similar to the EFI car), and those rubber pipes, which are easy to break after a long time.

Here's why:

1. Leakage of automobile oil circuit: the automobile is composed of various parts, among which the internal oil supply system of the automobile has a complex oil supply system, and with the growth of the life of the car, various problems will occur in the automobile oil circuit. Among them, the oil circuit will leak due to the loosening or fracture of the nut at the interface.

2. Aging of automobile oil circuits: Some oil circuits of automobiles are made of rubber, and with the growth of the service life of the car, this oil circuit will be aged, and then there will be leakage or rupture, which will lead to the volatilization of gasoline into the car.

3. Too much gasoline: There are corresponding standards for car refueling, and adding more or less will affect the car. When the car is refueled too much, it will cause the smell of gasoline in the car, and in serious cases, it will also cause the car to turn off when refueling.

4. Once the smell of gasoline appears in the car, it means that there is an abnormal situation in the car. We need to park the car in a safe area in time for inspection until the fault is eliminated before driving. Don't panic, calmly deal with the smell of gasoline**.

Here's how to remove the smell of gasoline in the car:

1. First turn on the air conditioner in the car and use the internal circulation mode (the windows need to be closed, and the air conditioner will be cooled), so that the smell of gasoline will disappear after a while.

2. You can go to the supermarket to buy a few bamboo charcoal with effective adsorption, activated carbon, sachets, etc., and put them in the car, which can effectively alleviate the smell of gasoline in the car for a period of time, and the effect of this method is also obvious.

3. Use lemon, grapefruit peel, etc. to effectively remove the smell of gasoline. Although this method is economical, it is very short to use, so remember to replace or dispose of it in time, otherwise these fruit peels are easy to bring other troubles, such as insects, mildew, etc.

4. Vinegar can also be used to remove the smell of gasoline. Use a suitable utensil, decorate with water, pour some vinegar, and put it in a suitable position in the car, so as to remove the smell of gasoline in the car, especially for new cars, and absorb methanol well.

Reasons for the smell of gasoline in the car while driving: 1. The fuel tank cap is not well sealed, and it needs to be replaced or the butter is 1 mm thick under the leather pad; 2. There are slight cracks or damages in the oil supply pipeline; 3. There is a gap between the oil pipe and the fuel tank, and if the clamp is not tight, it will cause a smell 4. The carbon tank is full of gasoline, if the gasoline is too full, there is a possibility that the gasoline will enter the carbon along the pipeline.

When the smell of gasoline is only present for a short time, it is not a big problem, but you need to pay attention to breathe more fresh air. However, if we smell gasoline for a long time, on the one hand, we will feel very unpleasant, and in severe cases, dizziness, nausea, vomiting and other conditions will occur, which will not only affect our appetite, but also seriously affect our mental state.

Let's talk about buying a car, using a car, maintaining a car, and repairing a car.

Let's take a look at the reason the teacher said.

Does it have anything to do with the canister solenoid valve and the canister?

Kiss <>

If the solenoid valve of the canister is damaged, there will also be a smell of gasoline in the car.
