What s going on with the smell of gasoline in the car, what s going on with the smell of gasoline in

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.

First of all, check whether the engine is leaking oil; Or replace the spark plug and 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, 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 are 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 deposit is relatively serious and needs to be repaired and removed.

The reason for the lack of cylinders is that 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.

Causes and countermeasures:

1. The rubber pipeline of the carbon canister is aging.

Some cars that are older or have run longer kilometers are prone to signs of aging when the rubber parts in the engine compartment are susceptible. 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. There is leakage in the gasoline pipe.

If there is a leak in the gasoline pipe, then there is a possibility that the smell of gasoline can 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.

Countermeasures: Tighten and repair interfaces.

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.

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.
