What is the situation when the car smells of gasoline, and what is the matter with the smell of gaso

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.

Reasons why the smell of gasoline is strong when the car starts cold:

1.When the outside temperature is low, when the water temperature and exhaust pipe temperature are low, and the engine starts colder in winter, the outside temperature is too low. At this time, the mixer is thicker, so some mixers can't burn fully and are discharged directly from the exhaust pipe, so you will smell some strong gasoline smell.

This should be normal.

2.It is also possible that there is a problem with the canister or the solenoid valve of the canister, which causes the mixture to be too thick when starting.

3.If the local temperature is low, there is too much carbon deposit inside the engine, and the mixture is not atomized well, which will also lead to this phenomenon.

4.If the solenoid valve is kept closed, the gasoline vapor in the canister will accumulate more and more, and eventually fill the entire canister, and the remaining gasoline vapor can only escape into the atmosphere, which will smell of gasoline.

5.There is a leak in the injector, which causes the mixture to be too thick, and the unburned mixture is exhausted from the exhaust pipe, resulting in a strong gasoline smell.

When the smell of gasoline is only present for a short period of time, the problem is not big, but you need to pay attention to breathing more

Fresh air is sufficient. But if you smell gasoline for a long time, on the one hand, you 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.

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

It depends on the situation.

The first situation: the rubber pipe of the carbon canister is aging - the rubber pipe between the carbon canister and the throttle valve is connected, and once it is aged, there may be leakage, so the smell of gasoline in the car is permeated.

The second case: a leak in the gasoline pipe – usually at the interface between the lines. When the engine compartment cover is opened, it can be judged that if there is a leak in the interface, after a period of time, the surface will absorb dust and form sludge.

Solution: Regularly check the gasoline pipe and tighten it in time, repair the interface, replace the gasket, etc.

The third situation: after disassembling the gasoline pump - the work of disassembling and assembling the gasoline pump needs to be completed in the car, and some omissions will inevitably occur in the process.

Solution: After disassembling and installing the gasoline pump, check whether there is no problem, if there is a problem on the road, please go back to the repair shop in time to check the installation defects of the gasoline pump.

The fourth situation: the smell of gasoline that is not the car is transmitted into the car from the external environment.

Solution: Turn on the air conditioner to use the internal circulation mode and open the sunroof to exhaust the air.

The fifth situation: caused by overfilling when refueling - when the refueling is full, it may cause gasoline to enter the canister along the pipeline, so that a large amount of gasoline vapor is released from the vent of the canister.

Solution: Turn on the air conditioner 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 dissipate when the car has driven for a while.

Other methods: you can inject ozone, or you can put some activated carbon. It's best to go to a car decorating shop and ask a professional. You can also put perfume or air freshener in the car.

3 points are more common.

1. The fuel tank sensor part 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.

Whether it is the smell of raw oil, or the smell of burned gasoline, if it is the former, one is fuel injection or oil pipe leakage (in short, check the front), and the latter is that the car is not well sealed (especially the chassis).

First, the sealing performance of the vehicle is not good.

Second, there may be some oil leakage in the vehicle oil circuit.

3. Other reasons.

Check whether the engine DU is leaking; Or replace.

Zhi spark plug to check the oil circuit, dao to see if there is leaking oil. Focus on checking the volume of high-pressure areas, such as near the injector.

The easiest thing is to check whether the fuel tank cover is not well sealed, and then check the carbon canister, and there are many pressure in the fuel tank, and it is easy to open the oil pump seal.

If there is a smell of gasoline in the cabin, it is likely that the oil outlet on the fuel tank, the return pipe, or the interface between the oil pump and the oil pipe are loose or cracked, because it is under the rear seats (and also under the trunk carpet), so the leakage will cause the smell of gasoline in the cabin. In this case, it should be checked and repaired as soon as possible to avoid serious consequences.

Generally, there will be a smell of gasoline when the cold car starts, which is a normal phenomenon, and the result of insufficient combustion of gasoline. If the hot car is also like this, it means that the carbon deposit is relatively serious and needs to be repaired and removed.

The reason for the lack of cylinders is that some cylinders of the engine do not work, and the car does not burn and is discharged with the exhaust, so there is a gasoline smell, the car is boring and consumes fuel.

Check whether the ignition system is that the cylinder is not ignited, whether it is high-voltage electricity or spark plug, and it is OK to eliminate the fault.

The smell of gasoline in the car is strong for the following reasons:

1.The rubber pipes of the carbon canister are aging.

In cars with long driving ranges, the rubber parts in the engine compartment are prone to aging.

2.There is a leak in the gasoline pipe.

If there is a leak in the gasoline pipe, then the smell of gasoline may enter the car through the air conditioning system.

3.There is residue when disassembling and assembling the gasoline pump.

Disassembling and assembling the gasoline pump needs to be completed in the car, and it is inevitable that there will be some residues in this process, if it is not cleaned up, it is possible to smell gasoline in the process of using the car.

4.The oil is too full.

If the gasoline is overfilled, there is a possibility that the gasoline will enter the carbon tank along the pipeline, and the carbon canister originally used to collect gasoline vapor will release excess gasoline vapor from the vent hole after entering the gasoline, and when the air conditioner is in the external circulation state, the gasoline smell will enter the car.

Hello, this is due to the aging of the rubber tube in the engine compartment of the canister, which will deteriorate after a long period of use, 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!

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.

Owners who have recently replaced the gasoline pump or disassembled the gasoline pump in the car, do not panic if there is a gasoline smell in the car, it is likely that the residue has not been cleaned up after the disassembly and assembly. 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.

When the temperature is low, the volatility of gasoline is reduced, and the environment for the formation of mixed gas is poor, resulting in the failure of some gasoline to burn fully. Special attention should be paid to the fact that if there is a gasoline smell in the car, accompanied by a pungent rubber smell, this may be a precursor to spontaneous combustion of the vehicle, and the owner should take inspection and preventive measures. Hope to adopt, thank you.

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

If there is a gasoline smell in the internal oil duct of the engine, consider the following reasons: if it is direct injection in the cylinder, consider the high-pressure oil pump, the injector leakage and the carbon canister solenoid valve is caused by it! If it is an ordinary naturally aspirated engine, consider the fuel injector, whether the pressure of the gasoline pump is too high, whether there is a problem with the solenoid valve of the carbon canister, etc.!

Question: My car is a Big Dipper X5 car, and there is a problem with the fuel injector, gasoline pump, and carbon canister solenoid valve, right, how to check it? Is it easy to repair?

Question: Is this oil used for change?

Q: Is there any connection between burning engine oil in my car and these problems? After repairing it, put the oil in it, just change the oil directly?

The answer is related, if the engine burns oil, there are many reasons, such as poor oil lubrication, bad oil use in the car, poor oil quality caused by too much carbon sludge inside the engine, which will accelerate the wear of mechanical parts inside the engine, such as piston ring damage, oil ring locking, etc.

Ask me what I do and how I say it so that I don't get caught up in the repair shop.

The following are the specific reasons for the smell of gasoline in the car: 1. If the gasoline is too full, the gasoline may enter the carbon tank along the pipeline, and the carbon tank originally used to collect gasoline vapor will release excess gasoline vapor from the vent hole after invading the gasoline, and when the air conditioner is in the state of external circulation, the gasoline smell can enter the car. 2. The gasoline pipe is leaking, and the gasoline smell may enter the car along the air conditioning system.

Leaks typically occur at the interface between the pipes. Open the bonnet, if there is a leak at the interface, the surface will absorb dust and form sludge. 3. Replace the gasoline pump or disassemble the gasoline pump, and the gasoline smell in the car may be due to the gasoline smell in the car caused by the residue not being cleaned up after disassembly and assembly, and you need to go to the repair shop to check whether the gasoline pump is installed correctly.

For many car owners, whether they are driving a new car or an old car, sometimes they feel that the gasoline in their car smells particularly strong. So what is the reason for the smell of gasoline in the car to be so strong? I suggest you take a good look.

In fact, one of the more important reasons is that there is too much gas. Many people like to see the amount of gasoline from the gas filler. In fact, it was already too full at this time, so the gasoline in the car smelled too strong. In this case, the gasoline gets into the canister.

The canister absorbs gasoline vapor. At this time, the gasoline vapor will be excessively emitted, and the smell will become obvious.

However, one might ask, how can your car have such a strong smell if you are not satisfied with gas? Since the tank is filled with gasoline vapor in addition to gasoline liquid, when the gasoline vapor gradually increases and cannot be distributed, the pressure in the tank will change accordingly, which will affect the normal fuel supply, and blockage may occur when filling gasoline.

Of course, the above points can be solved, that is, internal circulation.

It can be used for a while, and the odor can be removed after the external circulation is started, but if the gasoline pipe is leaking, then it is time to fix it. Be careful not to think that the strong smell of gasoline is a big problem with the car, which could be the reason why the gas is too full. I hope you can write it down carefully.

<> "What's the deal with the smell of gasoline in the car?"

What is the reason for the strong smell of gasoline in the car?

1. The rubber pipeline of the gasoline canister is aging, the rubber pipeline will gradually age with the growth of service life, after the rubber pipeline is aged, the gasoline vapor will leak out to the outside world, and after the vehicle opens the external circulation, the gasoline smell will enter the car from the air system;

After a long time, there is a lot of sludge formed at the interface of the oil pipe, and when the air conditioner is turned on, the smell of gasoline will enter the car with the air conditioning system, and the owner can also directly see whether there is liquid leakage from the rubber buckle of the gasoline pipe interface;

3. The gasoline pump and the corresponding pipeline are not cleaned, there will be some debris left, and a strong gasoline smell will be smelled in the car, so you need to send the vehicle to the 4S shop in time to check whether the gasoline pump is well installed, and then clean the gasoline pump and pipeline of the vehicle again;

4. If the gasoline is not fully and completely combusted, the incomplete combustion of gasoline exhaust will be directly discharged to the outside of the vehicle, and the gasoline smell will enter the cabin from the gap between the windows or doors, and the gasoline will smell when riding in the car; Stuffiness.

5. The connection between the fuel tank and the oil pipe is obviously loose or cracked, so that the gasoline will leak out directly, and the gasoline smell will be very serious, and the vehicle needs to be driven to the maintenance shop or 4S shop in time to avoid serious accidents.
