How to deal with the excessive smell of the car fuel tank?

Choose the addition of sunny weather and use the air conditioner to blow it dry. In addition, the hot air of the air conditioner can also be used to dry, which can remove the odor and effectively alleviate the odor in the car. Whether it is a relatively dry north, or a more moisture south, the car must be regularly and properly cleaned, go to the car wash shop or have the conditions to clean it yourself, in addition to the cleaning of surface dust, for the removal of odors, pay special attention to the cleaning of some dead corners of the car guards.

Especially sometimes you accidentally spill something in the car, and you must clean it up in time.

The smell of the car fuel tank is too heavy, it may be that there is an air leak, you should check the welding of the car fuel tank to observe whether there are any loopholes, if there are loopholes should be made up in time, this smell is too heavy will affect the environment, and even the danger will occur, it will burn in an environment where the temperature is too high, so I think we should find the problem of the fuel tank in time, if you can't find the problem, I recommend replacing the entire fuel tank.

Under normal circumstances, each car is equipped with an activated carbon tank on the right side of the engine, which is specially used to adsorb fuel vapor, when starting the engine, the activated carbon tank will absorb a part of the fuel vapor, but the excess gasoline can not be evaporated through the activated carbon tank, it may flow out of the trachea, after a bump along the way, the oil in the trachea cannot be volatilized for a long time, just sit in the fuel tank and smell a strong gasoline smell, so we should pay attention to the maintenance of the car, Especially in the summer, the oil should not be too full, and the fuel filter needs to be plugged in tightly, and after refueling, the oil pump seal in the fuel tank needs to be sealed.

The smell of gasoline in the car fuel tank is likely to be caused by a problem with the chassis of our car itself, which causes gasoline leakage, we can first go to the car repair shop to test, if there is no problem with the car chassis and fuel tank, we can try to place air freshener in the car, of course, if it is an old vehicle, it is normal for the car fuel tank to smell too heavy, and we need to replace the new car in time.

First check whether there are cracks or gaps in the fuel tank, and then see if there is any oil leakage, or whether there is gasoline in other places, and check the ventilation treatment to see if the ventilation is smooth. After checking, place some deodorizing items around the tank, such as carbon packets, etc.

It may be that the fuel tank cap is not well sealed and needs to be replaced or the butter is one millimeter thick under the leather pad. It may be that there is a gap between the connection between the oil pipe and the fuel tank, and the clamp is not tightly clamped. There is a gasoline oil gas vent next to the gasoline filling hole, which is used to evaporate gasoline into oil and gas when the fuel tank of the car rises due to the increase in temperature.

When this vent is blocked, the evaporated oil gas is released elsewhere because it cannot be released.

First of all, you have to do a test of your car to see if there is a problem with the car, and secondly, if you really can't stand the smell, you can install a perfume with your favorite smell, and then go to repair your car fuel tank, try not to let him affect your driving feeling.

First check whether the engine is leaking, replace the spark plug to check the oil circuit, see if there is oil leakage, focus on checking the high-pressure part, such as near the fuel injector, the simplest first check the fuel tank cover, whether the seal is not good, and then check the carbon canister, as well as the fuel tank, the air is more pressurized and easy to open the oil pump seal.

1. When the gasoline is overfilled, the gasoline may flow into the charcoal tank along the oil circuit, and after the charcoal tank is immersed in the gasoline, it is possible to excessively emit gasoline vapor from the ventilation hole, especially when the air conditioner is in the state of external circulation, the gasoline smell is particularly serious.

2. Gasoline pipe leakage, if the gasoline pipe leaks, then the gasoline flavor will naturally enter the car with the air conditioning system, and the leakage part generally appears at the pipeline interface, which can be seen from the daily inspection, and the leaking gasoline will absorb a large amount of dust after a period of time to form a thick sludge.

3. Another major reason is the aging of the rubber pipe of the carbon canister, which is responsible for connecting the rubber pipe between the carbon canister and the throttle, which will gradually age with the increase of mileage, and the aging will cause gasoline vapor leakage, so that the smell of gasoline will always be smelled in the car.

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.

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

Go to the 4S shop to check if your car's oil circuit system is leaking.

The smell of gasoline in the exhaust of the car is very strong, what's going on.

It may be that the engine has just started and has not reached the normal operating temperature, or it may be caused by damage to the oxygen sensor. After the engine is just started, it has not reached the normal working temperature, and the engine temperature is relatively low at this time. The electronic control unit will control the fuel injection system to inject more fuel, which can quickly increase the engine temperature.

At this time, the gasoline in the engine is not fully burned, and there will be a strong smell of gasoline in the exhaust gas. A typical car has two oxygen sensors, one behind the exhaust manifold and the other behind the three-way catalytic converter. The oxygen sensor detects the oxygen content in the exhaust gas and then feeds the signal back to the ECU, which adjusts the air-fuel ratio based on this signal.

If the oxygen sensor is damaged, the ECU is unable to precisely adjust the air-fuel ratio. At this time, there may be a strong smell of gasoline in the exhaust. Many riders prefer to heat their cars on the spot in the winter.

In fact, there is absolutely no need to heat them into place. At present, the EFI engine does not need to be heated in situ at all, and the correct way is to shift gears after ignition. When the car is hot in place, the engine is idling, and the gasoline is not fully combusted, and the carbon deposits in the engine will increase.

After ignition, it can be driven in gear, which can increase the load on the engine, and the engine can heat up quickly. And while driving, it also heats up the drivetrain. When you first start driving, don't let the engine run at too high speeds.

Recently, I often receive relevant messages from friends about "what is the reason why the car exhaust gasoline smell is very strong", and now I will explain it to you. The three-way catalytic converter for cold start and cold car does not work. 1. After the cold car starts, the mixed gas must be concentrated to maintain stable combustion, and the three-way catalytic converter in the exhaust pipe must be about 400 degrees to purify the exhaust gas; 2. Therefore, when the car is not completely hot, Wang Qi rolls around, and the exhaust will definitely smell of gasoline and liquid.

There is also a smell of gasoline in the hot car, the main reason for this problem is that the engine mixture is too thick, resulting in the gasoline is not completely burned, it is discharged, so that there will be a gasoline smell in the exhaust. Generally, when this happens, the engine fault light will be on. At this time, the failure of the spark plug, ignition coil, injector, spark plug or ignition coil can be checked, which may lead to ignition failure, and the poor atomization of the fuel injector will also affect the formation of a uniform mixture of gases in the cylinder, thus affecting combustion.

There is also a possibility that the three-way catalytic converter has failed, when the three-way catalytic converter fails or is damaged, the oxygen sensor will be seriously blocked, and it can no longer be purified, and there will be a gasoline smell. The only way is to replace it.

It could be because the engine didn't reach the normal operating temperature when it was first started, or it could be because the oxygen sensor was damaged.

The engine has just started, and it has not yet reached the normal working temperature moderate, and the engine temperature is relatively low at this time. The ECU controls the fuel injection system to inject more fuel, which quickly boosts the temperature of the mountain high engine. At this time, the gasoline in the engine is not completely burned, and there will be a strong gasoline smell in the exhaust.

A typical car has two oxygen sensors, one behind the exhaust manifold and the other behind a three-way catalytic converter. The oxygen sensor detects the oxygen content in the exhaust gas and feeds the signal back to the ECU, which adjusts the air-to-fuel ratio. If the oxygen sensor is damaged, the ECU will not be able to adjust the air-to-fuel ratio precisely.

At this point, there may be a strong smell of gasoline in the exhaust.

Many riders prefer to heat their cars on the spot in the winter. In fact, there is absolutely no need to heat them on site. At present, the EFI engine does not need to be heated in situ at all, and the correct way is to ignite and then gear up.

When the car is in situ hot drive, the engine is idling, and the gasoline combustion is not sufficient, and the carbon deposits in the engine will increase. After ignition, it can drive in gear, which can increase the load on the engine and heat up the engine quickly. And when driving, the drivetrain can also be heated.

Just don't let the engine speed go too high at the beginning of the drive.

It may be caused by the engine not reaching the normal operating temperature when it has just been started, or it may be caused by damage to the oxygen sensor. After the engine is just started, it has not yet reached the normal working temperature, and the engine temperature is relatively low at this time. The ECU controls the multi-injection of the fuel injection system, which allows for a rapid increase in engine temperatures.

At this time, the gasoline in the engine is not fully combusted, and there will be a heavy gasoline smell in the exhaust gas.

The car has two oxygen sensors, one behind the exhaust manifold and the other behind the three-way catalytic converter. The oxygen sensor detects the oxygen content in the exhaust gas and feeds the signal back to the ECU, which adjusts the air-fuel ratio based on this signal. If the oxygen sensor is damaged, the ECU will not be able to adjust the air/fuel ratio accurately.

At this point, there may be a strong smell of gasoline in the exhaust gas.

Many riders like to heat up in situ in winter, but in fact, it is completely unnecessary to heat up in situ. Today's EFI engines don't need to be heated in situ at all, and the correct way is to drive in gear after ignition.

In the case of in-situ hot cars, the engine is in idle condition, and the combustion of gasoline is not sufficient, and the carbon deposits in the engine will increase. After ignition, the gear is sliding, which can increase the load on the engine, and the engine can heat up quickly. And when driving, you can also let the transmission heat up the town system.

When you're just starting out, don't let the engine rev too high.
