The car smells of gasoline while driving, what is going on?

After starting the vehicle, there is sometimes a smell of gasoline, which is often normal. When the vehicle is cold-started.

, the driving computer will appropriately increase the amount of fuel injected according to the inlet air temperature and water temperature signal. At this time, the engine has not yet reached the normal operating temperature, and the gasoline cannot be fully combusted, and a small part of the incompletely burned gasoline will be discharged, so the gasoline smell will be smelled after starting the vehicle. If the owner of the car can always smell gasoline while driving, he should stop immediately because the car may be leaking oil.

If the vehicle is used for a long time, the oil pipe may age and crack. At this time, if you encounter bumpy road sections or pipes under pressure, fuel may leak out of these parts, so you must pay more attention at this time. At this time, you should pull over immediately, then prevent open flames, check the vehicle for oil leakage, and send it for repair as soon as possible.

It is very common to smell gasoline a few minutes before the vehicle starts, as it is the smell of gasoline in the exhaust gas.

In the winter, you will find that when you start the car, you will smell a particularly heavy smell of gasoline. Many car owners even wonder if their car is leaking oil, but after inspection, they find that there is nothing wrong with their car. In fact, it's not the car's problem, it's just the car's exhaust.

It's also normal to smell of gasoline in it, so don't worry about it when you start the car. The burning smell of plastic is a common odor in vehicles.

After all, there are a lot of electronic devices inside the vehicle, so there are also a lot of plastic products. If you smell burning plastic in your car, pay attention! This smell could be that the wiring of the appliances in the car is overheated, resulting in the rubber and plastic wrapped on the outside.

Because the outer sheath of the wire is relatively thin, even if the wire is short-circuited or overheated, the smell is not particularly heavy. In winter, the temperature will be relatively low, and this time the volatility of gasoline.

It will be slightly worse. If the fuel is injected at a normal injection rate, the evaporation of the gasoline actually entering the cylinder will be very low, resulting in a very low concentration of the mixture. This is when the engine is particularly difficult to start. If you want the car's engine to start properly, you need to inject more oil to increase evaporation.

It may be a fuel leak, or it may be that the rubber pipe of the carbon canister is aging, or there is a leak in the gasoline pipe, and the engine cover must be opened to understand the specific situation.

It may be that there is a problem with the oil circuit of the gasoline pump, and there will be some gasoline leakage at this time, and there will be a strong gasoline smell when driving.

Because the spark plug of the car is blocked, the sealing ring effect is relatively poor, the oil is not burned sufficiently, and then there will be a smell of gasoline.

When the car starts cold, the movement resistance of the engine is relatively large, and it is difficult to start. Therefore, in order not to affect the normal start, the ECU will increase the fuel injection volume during the cold start, increase the fuel concentration of the mixture, and facilitate the ignition start. When the engine starts cold, the surface temperature of the three-way catalytic converter is low, and the redox reaction cannot occur, and it cannot play a purification role at all, and some odors can still be smelled, especially in a closed and confined space, when starting the car, this smell is more obvious.

<> it is easy to loosen at the interface of the gasoline pipe, then the gasoline smell enters the air conditioner, and the gasoline smell can be smelled in the car. The solution is to tighten the connection of the gasoline pipe. Of course, you can also find a special repair shop for repairs.

Exhaust, this judgment is very simple, get off the car to the exhaust pipe with your hands to stay here to smell the smell of your hands, judge whether it is here, if there is a smell of raw oil, then we have to solve the problem for the engine, which is caused by insufficient combustion of typical colors, and it is very simple to find a solution to the problem.

How to solve the cold start. To solve the cold start, it is necessary to repair the wear of the metal surface and reduce the friction of various parts in the engine. It is to repair the wear between the piston ring and the cylinder wall, reduce the friction, make the gap between the piston ring and the cylinder wall smaller, increase the cylinder pressure, and fully combust.

Reduce friction, increase power and save fuel. When the car just started cold, the "three-way catalytic converter" had not yet reached the working temperature, and the exhaust gas was discharged without treatment, and it was easy to understand when it smelled some different smells from usual.

The activated carbon canister in the fuel system is designed to absorb the fuel vapor produced by our gasoline! When our activated carbon tank is damaged, our oil vapor will evaporate, and when we open the air conditioner external circulation in the car, we will suck the gasoline vapor outside the cabin into the car! If the gasoline is overfilled, there is a possibility that the gasoline will enter the canister along the pipeline, and the canister originally used to collect gasoline vapor will release excess gasoline vapor from the vent after being immersed in gasoline, and when the air conditioner is in the external circulation state, the gasoline smell will enter the car.

1. Under the condition that the outside temperature is very low, when the water temperature and the exhaust pipe temperature are low, and the outside temperature is too low when the engine is cold started during winter driving, the mixer at this time is relatively thick, so some mixers can not be fully combusted, and are directly discharged from the exhaust pipe, so some strong gasoline smell will be smelled. This should be normal. 2. It is also possible that there is a problem with the carbon canister or the solenoid valve of the carbon canister, resulting in the mixture being too thick when starting.

3. If the local temperature is low and there is too much carbon deposit inside the engine, the mixed gas atomization is not good, which will also lead to the occurrence of this phenomenon.

The main thing is that the car will add some gasoline when it starts, and there will be a gasoline smell during the combustion process, and the gasoline is volatile, so it will smell.

It may be because it has not been cleaned for a long time, so a lot of gasoline has a residual phenomenon, so the smell is relatively strong, and related cleaning can be carried out.

This may be due to the incomplete combustion of the car's fuel, or the car's fuel supply pipeline is damaged, the quality of the gasoline used in the car is not very good, or the engine has failed, and the oil has not been replaced for a long time, and it is necessary to carry out a comprehensive overhaul of the car in time to ensure the safety of the vehicle.

This may be because the car's fuel tank is leaking, and this situation is very dangerous, so when we encounter this situation, we must send the car to a professional car repair shop to repair, and do not bring unnecessary trouble to ourselves.

Because the gasoline pipe of the engine is broken, it is also possible that the fuel cap gasket is broken, so it will smell a gasoline smell, and it must be repaired in time.

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.

I believe that many car owners will encounter the smell of gasoline in the car when driving the vehicle. At this time, first of all, don't care if there is an oil leak that causes the smell of gasoline in the car, if the owner is smoking, you must quickly extinguish the smoke, and then check that it is the first cause of gasoline smell in the car. Next, let's explain the reason for the smell of gasoline in the car.

What is the reason for the smell of gasoline in the car:

1. There is a leak in the oil circuit of the car. If the screws at the oil circuit interface are broken or loose, it will lead to gasoline leakage;

3. The oil circuit is aging. Part of the oil circuit in the vehicle is composed of rubber products, which are fragile and will age after a certain period of time. As the oil circuit deteriorates, the gasoline leaks, and the smell of gasoline spreads to the car.

Is it dangerous to smell gasoline in the car?

Whether it is dangerous to smell gasoline in the car is mainly determined by what causes the smell of gasoline in the car. If the engine wants to reach the required temperature quickly because the gasoline is not burned enough, more gas will be sprayed from the fuel injectors, and the gas will enter the car through the gap in the vehicle, and the car will smell gasoline, then this situation is not dangerous. If the smell of gasoline in the car is very strong and lasts for a long time, it is dangerous, it is very likely that there is an oil leakage fault, and the owner will go to the 4S shop or repair shop for inspection and maintenance in 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.

Summary. Hello, dear, the car master will serve you, attentively, carefully and attentively answer for you, find the corresponding problem solution and solution for you, and will definitely provide you with a satisfactory answer! We hope you find this answer helpful.

Hello friend, there is a sudden smell of gasoline while the vehicle is moving, then this situation needs to be stopped in time for inspection. First, the first thing to check is whether it is the smell of gasoline emitted by your vehicle?

If so, check if there is any pipeline leakage Second, it is to see if there are traces of gasoline dripping at the chassis position? If there is, there is no way for the vehicle to continue driving, and it can only be inspected and repaired in time. Third, if everything is checked to be normal, then this is generally a problem with the canister, and you can take the time to replace the canister.

The car was driving for half an hour, and I felt the smell of oil, just a few seconds at most.

I don't know if it's the smell on the outside or the inside It's just a matter of seconds.

If everything is fine, then this does not affect the normal driving of the vehicle, take the time to check the carbon canister.

I'm a new car and it's only been half a year.

What about this new car. It's a good idea to take the time to check it out.

The windows were closed, and it smelled for a few seconds, and I couldn't figure out if it was outside.

I'm not sure if it's from outside, and it's generally not a big problem.

Will it be dangerous.

If this is only short-lived, there is no safety hazard if this gasoline smells, so you can rest assured.

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 filled with gasoline (absorbed).

The smell of gasoline in the car is generally from the air conditioning circulation intake, and you must pay attention to this problem, because gasoline is the most dangerous liquid in the car. According to your description, you can check the empty heel.

First of all, check whether there is any leakage in the engine fuel supply system, such as each pipe joint, fuel injector base, gasoline core interface, hose and other parts.

Secondly: it is necessary to check whether the ** parts of gasoline vapor are cracked, deformed, blocked, etc.

Third: Check whether the gasoline tank cap is well sealed.

And finally: the exhaust fumes are exhausted during the drive due to the traffic on the road, and at the same time you have chosen the air intake mode for outdoor circulation, so that the exhaust fumes enter your car.

The solution is simple and convenient.

First of all, we know the gasoline filling hole, and next to the gasoline filling hole, there is a gasoline oil and gas ventilation hole, its function is that when the fuel tank of the suffocating car rises due to the temperature, the gasoline will evaporate into oil and gas.

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.
