What s the deal with the smell of gasoline in the car?

Check whether the engine is leaking oil; Or replace the spark plugs.

Check the oil circuit to see if there is an oil leak. Focus on high-pressure areas, such as near injectors.

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, based on past experience, 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 is 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 deposition is relatively serious, and you can add a fuel companion to solve it.

It is the reason for the lack of cylinders, 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.

As soon as the car is opened, there is a gasoline smell treatment method.

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.

I don't know if you have ever encountered such a problem, that is, you often smell gasoline during driving a vehicle, so what is going on?

1. If the owner is in the process of driving the car. The smell of gasoline may be caused by a leak in the oil circuit inside the car, and the smell of gasoline in the car will be there. If it is for this reason, it is recommended that the owner should go to the nearest 4S shop to find a professional maintenance personnel for inspection, if it is found that the oil pipeline of the engine is indeed damaged, then it needs to be repaired before driving.

2. The reason why the smell of gasoline suddenly appears in the car may also be because the owner adds more when refueling, and due to the uneven road surface, there will be overflow, and it is inevitable to smell a strange smell of gasoline.

3. Generally, most of the owners like to drive the external circulation when driving a motor vehicle, at this time, the smell of gasoline will naturally flow into the car through the external circulation of the car, then the owner only needs to turn off the external circulation of the car immediately, and will never smell this gas and oil smell again after a few hours.

The smell of gasoline in the car may be caused by the aging of the rubber pipe of the carbon canister, the leakage of the gasoline pipe, the residue when disassembling the gasoline pump, and other reasons. If there is a smell of gasoline in the compartment, it is likely that the oil outlet on the fuel tank, the oil return pipe, or the interface between the oil pump and the oil pipe are loose or cracked, so the leakage will cause the smell of gasoline in the compartment.

Reasons why cars smell of gasoline:

1. Some cars with a long age or a long number of kilometers are prone to signs of aging in the rubber parts in the engine compartment. The gasoline vapor that should have been channeled into the intake manifold leaked into the engine compartment and the air conditioning system became a way for the smell of gasoline to enter the car.

2. If the gasoline pipe does leak, then the gasoline smell may enter the car along the air conditioning system. Leaks typically occur at the interface between the pipes. When you open the engine compartment cover, you can generally see that if there is a leak at the interface, after a period of time, the surface will absorb dust and form sludge.

In addition, if you touch the pipeline interface, you will know if there is a leak.

3. The disassembly and assembly of the gasoline pump needs to be completed in the car, and some residues will inevitably appear in this process, if it is not cleaned up, it is possible to smell gasoline in the process of using the car. (Photo by Li Linwei) @2019

1. Aging of rubber pipelines of gasoline purification carbon canisters:

For older cars, the rubber parts in the engine compartment are prone to aging. The carbon canister to the throttle valve is connected by a rubber pipe, which may leak to the engine compartment as long as it is aging, and the rubber pipe needs to be replaced in time.

2. Leakage at the gasoline pipe interface

If there is a leak in the gasoline pipe, the smell of gasoline may enter the car along the air-conditioning system. The leakage is generally at the interface between the pipes, and the engine compartment cover is opened to be judged by visual inspection, because once the leakage occurs, a sharp layer of sludge will appear on the surface over time. It needs to be tightened and repaired.

3. The sealing performance deteriorates after disassembling and assembling the gasoline pump

There may be car owners who will change the gasoline pump or disassemble the gasoline pump, and the gasoline smell in the car may be due to the residue is not cleaned up after disassembly, it is best to go to the repair shop to check whether the gasoline pump is installed correctly. Generally, it will only involve the disassembly and assembly of the gasoline pump when it is replaced or when there is a related failure. The replacement cycle of the gasoline pump is about 100,000 kilometers.

4. The car is too full of oil:

If the pipeline in the activated carbon canister system enters the gasoline, the liquid fuel enters the carbon canister not only to the carbon canister itself, but also flows into the intake channel along the pipeline to lead the flower plug to "drown", resulting in the serious consequences of the car turning off until it cannot be started.

Because there are many such situations, that is, the sealing ring, including the pipeline, is aging and leaking, as long as the water leakage is a very big safety hazard. In the middle of the cockpit of the car, in the rear of the car, as long as there is a smell of ** and gasoline, it must be cleaned out, otherwise it will be very, very dangerous.

As long as you can smell the smell, seize the time to do inspection and treatment to prevent the car from spontaneously combusting. Common causes of gasoline odor in cars:

1.The 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.

There are several possible scenarios in which the car smells of gasoline:

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

2.Minor cracks or damage to the oil supply lines;

3.There is a gap between the tubing and the tank.

4.The canister was filled with gasoline. Also, inspect the pipes for the steam filter inside the hood, the pipes for the carburetor, the pipes for the rubber sheet, which are prone to cracking over time. @2019

Under normal circumstances, there is no smell of gasoline in the cab of the car, if the owner can smell the smell of gasoline in the cab, there may be a problem with the car, so what is the reason for the smell of gasoline in the car?

1. If there is a problem with the return pipe of gasoline, then there will be a gasoline smell in the cab. If the car is used for a long time, cracks may appear in the car's gasoline return pipe, and then the gasoline will leak out, and the smell of gasoline will enter the cab. If the owner finds that the cab smells of gasoline, he can first check whether there is a problem with the return pipe, and if there is a problem, he should go to the auto repair shop in time to deal with it.

2. After the car has been used for a long time, cracks may appear in the oil supply pipeline of the car, and then gasoline leaks. If the oil supply pipeline leaks gasoline, then it is more dangerous for the car to drive, and the car owner will deal with it in time.

3. If the filter of the carburetor is not replaced for a long time, it will also cause the cab to smell of gasoline. If the filter is not replaced for a long time, the filter will clog, the filtration effect will be worse, and then the smell of gasoline will volatilize into the cab. The owner can replace the filter element, or clean the filter element to solve this problem.

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.

The reasons for the smell of gasoline in the car are the aging of the rubber pipeline of the gasoline purification carbon canister, the leakage of the gasoline pipe interface and the residue that has not been cleaned. Aging of rubber pipes of gasoline canisters: The rubber parts in the engine compartment of old cars are prone to aging.

The canister is connected to the throttle valve by a rubber pipe, which can leak into the engine compartment as soon as it ages. Solution: The rubber hose needs to be replaced in time.

Leaks at gasoline pipe interfaces: If gasoline pipes leak, gasoline odor may enter the car along the air conditioning system. Generally, the leak is at the interface between the pipes, and the engine compartment cover is opened to visually judge, because once the leak occurs, a layer of sludge will appear on the surface over time.

Solution: Fastening and repair is required. Residue is not cleaned up:

The gasoline pump replacement cycle is about 100,000 kilometers. Some car owners may replace or disassemble the gasoline pump, and the gasoline smell in the car may be caused by the residue not being cleaned up after disassembly. Workaround:

Go to the repair shop to clean up the debris.
