There is a smell of gasoline in the car, how can I quickly find the cause?

There is a smell of gasoline in the car, how can I quickly find the cause? If there is a smell of gasoline, stop immediately as these two smells are red flags and the vehicle may **. On the premise of ensuring personal safety, to find gasoline, first through the sense of smell for preliminary identification, no smell with other specific inspection and then open the hood, pay attention to ensure personal safety, musty smell in the car:

Long-term failure to clean the air conditioning system leads to the growth of bacteria in the evaporator and airway, resulting in mildew and needs to be cleaned.

<> there was a smell of gasoline in the car. Can cars spontaneously combust? It is most likely that the residue after disassembly has not been cleaned up.

The probability of this situation is very small, and the replacement cycle of the general gasoline pump is 100,000 kilometers. However, the gasoline filter is connected to the gasoline pump, and the replacement cycle is short, and it needs to be disassembled when replacing the gasoline pump. In this case, just check that the gasoline pump is installed correctly and clean the surroundings.

The possible causes of the odor of automobile gasoline, the aging of the rubber tube of the carbon canister. The rubber hose in the engine compartment will deteriorate after long-term use, and it is easy to deteriorate when the vehicle is older. Once aged, gasoline leaks into the engine compartment.

An empty system allows gasoline fumes to enter the car. So once the rubber tube is aged, it needs to be replaced in time The canister is filled with gasoline. Also, check the steam filter pipes, carburetor pipes, and rubber sheet pipes on the hood, which are prone to cracking over time.

There is a leak in the connection of the gasoline pipe. There may be a leak in the connection of the gasoline pipe, which may allow the gasoline smell to enter the car through the air conditioning system. If the owner finds that there is a smell of gasoline in the car, he should check the interface of the gasoline pipe - open the hood, it is easy to tell whether there is oil leakage at the interface of the gasoline pipe, because for a period of time after the oil leak, the surface of the oil can be coated with mud.

If a leak is found at the tubing interface, the connection should be tightened or repaired. Although there was no leak at the filler, the gasoline went down the pipe into the canister. When the canister releases steam, it will be released along with the gasoline.

If the air is in the external circulation state at this time, it may smell of gasoline.

There was a smell of gasoline in the car. Solution: If it is caused by the aging of the carbon canister hose, replace the relevant aging hose. If it is caused by overfilling, adjust the empty to internal circulation state. After driving for a while, the gasoline smell gradually disappears when consumed naturally.

1.The rubber pipes of the carbon canister are aging. Rubber tubing is used to attach the car's carbon canister to the throttle valve. Once the rubber tube ages, gasoline may leak and the car will smell of gasoline.

2.The gasoline pipe is leaking. Gasoline pipeline leaks usually occur at the junctions between pipes. Open the engine compartment cover for inspection. If there is a layer of sludge near the connection between the pipes, the gasoline pipe is leaking. Of course there will be a gasoline smell.

Solution: Tighten the repair interface and replace the gasket.

3.Too much gas. If the gasoline is too full, the gasoline may go down the pipe into the canister. When the carbon canister used to collect gasoline vapor invades the gasoline, it releases excess gasoline vapor through the vent. When the empty is in the external circulation state, the smell of gasoline enters the car.

Solution: Adjust the empty-to-inner circulation state, after driving for a period of time, the gasoline smell will gradually disappear after natural consumption. The most straightforward way is to add a little less.

4.The non-gasoline smell of the vehicle is introduced into the vehicle from the external environment.

It's better to solve this problem. Empty use the inner circulation mode, open the sunroof exhaust.

The smell of gasoline in cars is something we encounter a lot. Under normal circumstances, car owners think that opening the windows can get some air and wash away odors. When there is no smell, they continue to drive, but few car owners start with the ** of the gasoline god stop smell.

In order to protect their health, they still have to look for the source of the fault.

Oil leakage from the gas tank:

The pungent smell in the car is caused by an oil leak. Open the cabin and check the fuel tank for oil leaks, or omit oxidative deterioration around the fuel tank, which can cause odors in the car. Car owners need to close the gas tank cap and clean the surrounding oil stains.

The oil is too full, and there is a lack of fuel in the car:

Whether it's oil or gasoline, if you add too much oil, the oil in the car will stay around the gas tank in the car along the pipes. This car oil may remain near the empty switch. When

Rubber aging: There are many tubing around the tank for input and output oil. These tubings are all made of rubber.

Over time, rubber will inevitably deteriorate, and car oil will leak out along the crevices of the aging rubber, causing a pungent odor in the car. It is necessary to replace the new oil pipe in time and ensure that the oil pipe is connected normally.

When we drive, the smell of gasoline in the car is unavoidable. Regardless of whether it is the cause of the oil leak, it is necessary to solve the problem at the source, rather than opening the window for ventilation, and put health and safety first.

Millions of car purchase subsidies.

<> "What should I do if my car smells of gasoline?"

The weather is getting warmer. Some team members can always smell the gasoline in the car when driving. They can't help but panic. Shouldn't it be spontaneous combustion?

Don't panic, when you encounter such a situation, you should be calm and deal with it. You must first identify it by its smell. If there is a pungent rubber smell mixed in, it is best to stop and check to ensure personal safety.

1. The gasoline is too full.

If the owner fills up the gasoline when refueling, although there is no oil leakage from the fuel filler, the gasoline will enter the carbon tank along the pipe, and the carbon tank will be released together with the gasoline when the steam is released. You may smell the gasoline in it.

However, as long as the gasoline in the canister is used up, the excess gasoline vapor in the canister will be burned into the cylinder through the action of the negative pressure of the engine, and there will be no more gasoline vapor overflow.

It is recommended that you do not add too much fuel, especially during the hot summer months.

2. There is a problem with the oil and gas evaporation control system.

The oil and gas evaporation control system is simply a carbon canister and solenoid valve on the car. Since gasoline is volatile, the gasoline vapor in the tank needs to be discharged in a suitable way, otherwise the more it accumulates, the greater the safety hazard.

Due to the weakened adsorption effect of the carbon canister, the gasoline in the steam cannot be completely absorbed, resulting in the gas discharged from the carbon canister containing gasoline, and the carbon canister of some models is located in the engine compartment close to the air - conditioning filter. Suck into the engine and rarely escape.

When the accelerator is released, the negative pressure disappears and steam escapes from the canister exhaust port. This will cause some models to smell of gasoline when the throttle is opened. So in this case, the canister should be replaced.

3. The fuel tank cap is not tightly sealed.

Sometimes there are cold and hot cars that don't smell of gas. This can be caused by poor sealing of the fuel cap and gasoline vapor leaks. Check the seal around the fuel tank cap. If it is tilted, it can be repaired. If there is no abnormality, it can be replaced as a whole, and it is not expensive.

This occasional odor problem is not too big, and it is not very urgent to repair, and it can be checked and repaired together when there is time or repair.
