What is the reason for the smell of gasoline 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.

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.

The smell of gasoline in the car is high, which is due to the following reasons: 1. Aging of the rubber pipeline of the carbon canister: the rubber parts in the engine compartment of the car with a long mileage are easy to age; 2. There is leakage in the gasoline pipe

If there is a leak in the gasoline pipe, the smell of gasoline may enter the car along the air conditioning system; 3. There are residues when disassembling and assembling the gasoline pump: the disassembly and assembly of the gasoline pump needs to be completed in the car, and some residues will inevitably appear in this process. 4. The oil is too full: if the gasoline is too full, there is a possibility that the gasoline will 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 entering the gasoline, and when the air conditioner is in the external circulation state, the gasoline smell will enter the car.

There are 5 reasons why the smell of gasoline in the car is high:2. The oil pipe leaks, and the smell of gasoline will enter the car with the air conditioning circulation.

3. The aging of the rubber pipe of the carbon canister will lead to the leakage of gasoline vapor, so as to smell the smell of gasoline.

4. The gasoline pump has just been disassembled or replaced.

5. Gasoline combustion is unsafe, especially when the engine is relatively cool, the engine work efficiency decreases, resulting in the aggravation of gasoline smell.

4. Do not take plastic containers to fill gasoline directly.

6. Do not repair the car in the station, especially the old vehicle can not open the machine cover of the car.

7. It is strictly forbidden to move fire-fighting equipment at will.

The reasons for the great smell of gasoline in the car: 1. The rubber pipeline of the gasoline purification carbon tank is aging: the rubber pipeline between the carbon tank and the throttle is connected by a rubber pipeline, and the aging may leak to the engine compartment, and the rubber pipe needs to be replaced in time; 2. Leakage at the gasoline pipe interface

The leakage is generally at the interface between the pipelines, the gasoline smell enters the car along the air conditioning system, and the engine compartment cover is opened to judge by visual inspection, and a layer of sludge will appear on the surface for a long time of leakage, which needs to be tightened and repaired; 3. The sealing performance deteriorates after disassembling and assembling the gasoline pump: the residue is not cleaned up after disassembly and assembly, go to the repair shop to check whether the installation of the gasoline pump is correct; 4. If the gas in the activated carbon canister system enters the gasoline, it will not only pose a hazard to the carbon canister itself, but also flow into the intake tract along the pipeline, resulting in the serious consequences of the car turning off until it cannot be started.
