What to do if there is a smell of alcohol in the car when you step on the accelerator, and sometimes

Buick Kaiyue 100 kilometers 1, check whether the air filter is unblocked. 2. Check the ignition timing. 3. Check whether there is oil leakage in the pipeline.

If the previous ones are fine. 4. Check whether there is black smoke coming out of the exhaust pipe after driving. If there is no problem with the air intake, it means that there is too much fuel injection.

5. There is no backfire, and the sound of firecrackers is sometimes like firecrackers. 6. Check the engine oil to see if there is a strong gasoline smell in the oil. Has the oil become too much...

7. Check whether the water temperature is normal and whether it will overheat. 8. Check whether the clutch is normal and whether it will slip. It's just that the uphill slope is weak, the acceleration is poor, etc.

9. Check the brakes to see if there is any drag brake phenomenon, brake suddenly on the flat road, and look at the brake marks. 10. Also, run 100 kilometers without air conditioning to see if it will be like this! Before talking about the topic of fuel economy, let's talk about several important factors that affect the fuel consumption of automobiles.

First of all, it is the weight, the speed of the vehicle, and of course, the driving style, the body design, the mechanical properties, the maintenance condition, etc. However, what we can do with our hands is to reduce the burden. Check your steering wheel and tyres regularly to make sure the tyre pressure is normal.

If the tire gas is not enough or too much gas, it will increase fuel consumption, and generally the tire pressure that meets the specified requirements can reduce fuel consumption by one percent, so the tire pressure should be checked regularly. And don't change the size of the tires at will. When driving on the road, you should keep an appropriate distance between vehicles, develop good driving habits, and do not overtake and slam on the accelerator to accelerate.

Because, when you step on the brake, it means that the oil you just gave is going to be converted into the heat energy of the brake, and the second is not kinetic energy. In addition, avoid changing lanes often when driving, we all know that the straight-line distance between two points is the shortest, if you often change lanes, the driving distance is relatively long, so it will also consume a little more fuel, and often change lanes, in order to overtake, you must step on the accelerator, fuel consumption will naturally increase. It is necessary to pay attention to more maintenance and reduce the burden on the body.

If there is a problem with the engine, fix it immediately, because no matter how big or small the problem is, it will reduce the efficiency of the engine and waste your gas. Also pay attention to keep the vehicle clean, wash and wax the car frequently to reduce air resistance and improve fuel economy. Also, clean up the excess items in the trunk of the back of your car in time, because the weight of the car is directly proportional to the fuel consumption, and the heavier the car, the more fuel the car consumes.

Automotive engineers often say: to increase the power of the engine by 5kw, it is better to make the car **10 kg. It can be seen how much the weight of a car can affect the driving performance and fuel consumption of a car.

Ethanol gasoline, check the engine compartment for leaking gasoline.

Summary. Hello, according to your question, when you step on the accelerator, there will be a big smell of gasoline in the car, which may be due to the following reasons:

Situation: The failure of the canister causes abnormal combustion, which smells of gasoline, which needs to be checked by a technician.

The above are the solutions and solutions related to stepping on the accelerator and smelling the smell of gasoline, I hope my help to you.

Does anyone know that when a car steps on the accelerator once, there will be a big smell of gasoline in the car, and what is going on?

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, according to your question, if you step on the accelerator, there will be a lot of gasoline smell in the car, which may be due to the following reasons: There is a leak in the fuel pipe and the road is not good Burning is not good There is an abnormal situation in the carbon canister: It is recommended that you open the cabin cover to let it be, visually check whether the engine is leaking fuel, and then carefully observe whether there are signs of fuel leakage on the ground where the vehicle is parked.

Situation: There is a problem with the combustion system of the vehicle, resulting in poor combustion, so that the driver smells gasoline Situation: The failure of the carbon canister leads to abnormal combustion, so as to smell the smell of gasoline, which needs to be checked by a technician.

The above are the solutions and solutions related to stepping on the accelerator and smelling the smell of gasoline, I hope my help to you.

Solution: Replace the canister.

By understanding the structure of an oil and gas evaporation control system, we know that a carbon canister is an important component of it. Due to the weakening of the adsorption effect of the carbon canister, the gasoline in the steam cannot be completely adsorbed, resulting in the gas discharged from the carbon canister containing gasoline, and the carbon canister of some models is in the engine compartment close to the position of the air conditioning filter, and the oil and gas are sucked into the engine during normal driving, and rarely escape.

When the throttle is released, the negative pressure disappears and steam escapes through the canister vents. As a result, some models will smell gasoline as soon as they release the throttle when the internal circulation is opened.

Due to the blockage of the vent of the carbon canister, the oil pump continuously pumps oil during the normal driving of the vehicle, causing the negative pressure in the fuel tank to rise, but the vent cannot quickly replenish air to adjust the negative pressure, resulting in the fuel tank being sucked flat.

When the throttle is released, the oil pump stops working, the negative pressure disappears, and the fuel tank rebounds with a muffled sound. In this case, under extreme conditions, the oil tank can even damage the pump if the oil tank is flattened to a high degree.

After the car is parked at high temperatures for a long time, the oil and gas cannot be discharged due to the blockage of the vents, so the steam collects in the fuel tank, and when the fuel tank cover is opened, it will be exhausted outward.

Solution: In this case, check the vent at the bottom of the canister, under normal circumstances, dredge the vent can solve the problem, and it does not have to be replaced.

The smell of gasoline in the car is generally caused by the following conditions: 1. The gasket in the fuel tank cap is aging or uneven (replaced) 2. The fuel injector and throttle have not been cleaned for a long time and produce dirt, resulting in insufficient gasoline combustion (cleaning) 3. The gasoline filter is dirty or the connecting hose interface is loose and aging (replaced) 4. The gasoline purification carbon tank is dirty or fails (replaced) 5. The fuel tank connecting hose is aging and loose (replaced) 6. The car has poor sealing performance (repair) The above reasons have been solved, and your car should no longer smell of gasoline.

1.Insufficient throttle intake. The throttle valve intake is insufficient, and the airflow information is incorrect, resulting in a large oil smell after ignition, and the throttle needs to be repaired in time.

2.The engine has too much carbon deposit. Excessive carbon deposition in the engine and poor atomization of the mixed gas will also lead to a heavy oil smell after ignition, so it is necessary to clean up the carbon deposition in the engine in time.

3.Excessive carbon build-up in cylinders and pistons. Excessive carbon deposits in the combustion chamber and piston can lead to insufficient cylinder pressure, so carbon deposits in the cylinder and piston need to be cleaned.

4.The gasoline pipe is leaking. There is a leak in the gasoline pipe, and sludge forms at the connection of the oil pipe. The smell of engine oil enters the car with the air conditioning system, and the gasoline pipe needs to be repaired in time.

5.Failure of the canister. This can also be caused by a malfunctioning canister or canister solenoid valve, which needs to be replaced.

6.Injector leaks. Oil leakage from the grease nipple will also cause the oil smell to be strong after ignition, so repair the grease nipple in time.

7.Aging of rubber hoses. The rubber tube of the carbon canister is aging and needs to be replaced in time.

8.The outside temperature is very low. If the outside temperature is relatively low in winter, the mixture may not burn sufficiently, resulting in an oily smell. It is advisable to heat the vehicle first and wait for the moisture and exhaust pipe temperature to become high before starting the vehicle, which may alleviate the situation.

9.The fuel tank is leaking. Observe the parking area for oil leaks, the fuel tank may be leaking. You need to go to the repair shop in time to repair or replace the tank.

10.Gasoline residue. If the vehicle's gasoline pump has just been removed, check whether there is any gasoline residue and need to be cleaned up in time.

Hello dear! The reasons for the original limb brother are as follows: 1. Under the condition that the outside temperature is very low, when the water temperature and exhaust pipe temperature are low, and the outside temperature is too low when the engine starts cold during winter driving, the mixer at this time is relatively thick, so some mixers can not be fully burned and are directly discharged from the exhaust pipe, so some strong gasoline smell will be smelled.

This is normal. 2. It may be because of 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.

4. If the solenoid valve has been closed, the gasoline vapor in the carbon canister will gather more and more, and eventually fill the entire carbon canister, and the rest of the gasoline vapor can only escape into the atmosphere, and the smell of gasoline will also appear. 5. There is a leakage phenomenon in the fuel injector, which leads to the mixture being too thick, and the unburned mixture will be discharged from the exhaust pipe, thus causing the gasoline smell to be large. Dust-based.

There is a large smell of gasoline in the car, and accompanied by the failure of the accelerator, the related reasons are as follows, these points first, the vehicle throttle is too dirty caused by this phenomenon, it is recommended to clean up the throttle of the vehicle engine, and then redo the matching of the throttle Second, the vehicle into the liquid gas burial system has a leakage phenomenon caused by this failure, this focus on checking the relevant vacuum pipeline and carbon canister solenoid valve finger third, the phenomenon caused by too much carbon deposition inside the engine, This is the need to clean the intake duct carbon deposits, valve base carbon deposits and three-way catalytic converters. Fourth, the vehicle engine exhaust system failure, this focus on checking the exhaust valve, if the exhaust valve is damaged, it needs to be replaced in time. Fifth, the vehicle engine has a lack of cylinder failure, show this focus, check the ignition coil and spark plug, if there is a problem, you need to replace it in time!

Some cars have some gasoline smell that is normal, but it can't be too heavy, depending on your model. Carburetor cars are normal because they don't burn enough when they start. If it is an EFI truck, you can preliminarily judge from the following situation:

If you encounter a fault when stepping on the accelerator to accelerate, and the gasoline smell in the car is relatively large, you should pay special attention to whether the pipes in the carbon canister system are damaged.

If the engine is started and the speed of the car is weak when idling, it is necessary to pay attention to whether it is caused by the blockage of the air inlet and filter of the carbon canister.

If the engine stalls or doesn't start easily, check the canister solenoid valve that could cause the problem. Because if the solenoid valve has been in the open state, the mixture of the intake tract of the engine has been in a thickened state, and at the same time, the control unit of the engine has not controlled the work of the solenoid valve of the carbon canister at this time, and will not issue an instruction to reduce the amount of fuel injection, which will cause the mixed smell to be strong when the car is hot, please check the temperature sensor.

There may be oil leakage in the oil supply circuit of the car or oil leakage in the oil return pipe, and the engine may not burn completely.

Possible causes of the smell of gasoline.

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

Engine compartment. The rubber hose will deteriorate after long-term use, and older vehicles are prone to this problem. Once it ages, there is a risk that gasoline can leak into the engine compartment. The air conditioning system then allows the smell of gasoline to enter the car. Therefore, once the rubber hose is aged, it needs to be replaced in time!

2. There is a leak in the gasoline pipe interface.

Leaks may occur at the joints of the gasoline pipes, causing the smell of gasoline to enter the vehicle through the air conditioning system. If the owner notices the smell of gasoline in the car, he should check the interface of the gasoline line - open the engine compartment cover, it is easy to tell whether the gasoline pipe interface is leaking, because a layer of sludge will appear on the surface after a period of leakage. If the gasoline pipe interface is found to be leaking, the connection should be tightened or repaired.

3. The gasoline pump has been disassembled and installed in the car.

Owners who have recently replaced or disassembled a gasoline pump, do not panic if there is a gasoline smell in the car, it is likely that the residue has not been cleaned up after disassembly. This is less likely to happen, and the typical replacement interval for a gasoline pump is 100,000 km. However, the gasoline filter element is connected to the gasoline pump, and its replacement cycle is shorter, and the gasoline pump needs to be disassembled and assembled when replacing.

In this case, just check that the petrol pump is installed correctly and clean up the perimeter.

4. Overfilling up gasoline.

Sometimes the owner of the car refuels the gasoline too full, although the fuel filler does not leak, the gasoline enters the carbon tank along the pipeline, and the carbon tank is released together with the gasoline when the steam is released, if the air conditioner is in the external circulation state at this time, the car may smell the smell of gasoline.

Solution: As long as the gasoline in the canister is consumed, the excess gasoline vapor in the canister will enter the cylinder for combustion through the action of negative pressure of the engine, and there will be no more gasoline vapor overflow.

2. Pay special attention.

If there is a gasoline smell in the car, accompanied by a pungent rubber smell, this may be a precursor to spontaneous combustion of the vehicle, and the owner should take inspection and preventive measures.

Hello, first of all, you need to check whether the gasoline pipe is cracked, if there is a suggestion to replace it first, and then try it, it will not be broken under normal circumstances, I hope it can help you.
