Why does the car stall when it is driven and it smells of mush?

1. Circuit failure: This may be due to low-voltage power failure and flameout during driving. At this time, you can mainly check the ignition and starter switches, as well as the fuse box.

2. Failure of electrical devices: This problem is generally the failure of the ignition coil, capacitor and electronic ignition module.

3. Oil circuit failure: the gasoline pump is damaged, the oil pipe is broken, the gasoline inlet is blocked, and the fuel tank is empty.

4. Sensor failure: throttle position sensor, intake flow sensor, intake pressure sensor, crankshaft position sensor, camshaft position sensor failure and other faults, if the sensor fails, there will also be flameout faults.

If the car smells mushy while driving and the engine is still stalling, it means that there are parts or wiring in the car that have been burned, and it is best to go to an auto repair shop to see.

If the car stalls while driving, and there is a fox smell, it means that the car has been burned, and in this case, it is necessary to repair, the car must have a problem, and you should go to a repair shop to repair the car.

It could be that you didn't control the throttle properly. If you burn the Tiger Guard, your oil cylinder may be burned. There may be other reasons.

Hello. Check to see if the line is short-circuited and burned. Hope it helps.

If it is a manual transmission, then this stalling is normal, because it is caused by your improper operation.

What kind of car will stall when driving, and there is a fox smell, I think what I can say may be your brake pads, the reason why it has broken here, you can go to the repair shop to take a look.

Yours hesitated.

How did I start to be afraid of saying the wrong thing in front of me.

You're looking out the window at an unrelated scene.

Be silent and your grace.

I want to accompany you and pretend to be okay.

Naivety put the separation delay.

Reality is more honest than we are.

I've seen you say for a lifetime.

I've seen you take care of everything.

I've seen you say you want time to stop.

Take me by the hand and call my name.

I've seen the way you lie.

I've seen love deteriorate naturally.

Even if you miss it, that's the end of it.

At least I've seen the way you love me.

Silent air pierces your heart.

You've been sad and sad a few times.

An unfamiliar look on your face.

It's the interpretation you give.

I watch your wandering mind.

I also saw my senseless persistence.

Don't say you love me anymore, honey.

Because I've seen the way you love me.

The most beautiful sunset I've ever seen.

It's you who accompany me to see the sea.

Even if you miss it, that's the end of it.

At least I've seen the way you love me, cite=

The way to judge is very simple, that is, if there is no engine failure light on the dashboard, the carbon canister will basically not be faulty; The canister solenoid valve will have a crisp "click" sound in normal operation, and there is no problem if the sound is normal, otherwise it needs to be checked and replaced.

As for smelling a strong smell of gasoline, it may also indicate that the canister is damaged, but generally speaking, the smell of gasoline is still after the car is hot. On the other hand, if you smell a little gasoline during a cold start, it is normal, because the fuel injection will be thickened during the cold start, and the air-fuel ratio is a little out of balance. To put it bluntly, the adequacy of fuel combustion will be very poor, and the exhaust gas will contain excessive hydrocarbons (HC-the main substance of gasoline), and the combustion adequacy will be improved a lot after the car is heated, and there should be no obvious smell after that.

First of all, pay attention to check whether the pipes in the canister system are broken.

Gasoline vapor is discharged directly into the atmosphere along the damaged area, causing the smell of gasoline in the car. If the pipeline leaks at this time, it is air instead of fuel vapor that enters the engine inlet will inevitably cause the engine mixture to be too thin, resulting in the phenomenon that it is not easy to start.

It is also possible that there is a problem with the solenoid valve of the canister. If the solenoid valve is always closed, the gasoline vapor in the canister will accumulate more and more, and eventually fill the entire canister, and the rest of the gasoline vapor can only escape into the atmosphere, polluting the environment and wasting fuel.

This can also happen if the injector leaks. It is recommended to go to a 4S shop or repair shop for on-site inspection according to the above conditions.

, the gasket in the fuel tank cap is aged or uneven (replaced).

2. The fuel injector and throttle have not been cleaned for a long time, resulting in dirt, resulting in insufficient combustion of gasoline (cleaning) 3. The gasoline filter is dirty or the connection hose interface is loose and aging (replaced) 4. The gasoline purification carbon tank is dirty or invalid (replaced).

5. The connecting hose of the fuel tank is aging and loose (replaced).

6. The sealing performance of the car is not good (repaired).

With the above reasons solved, your car should no longer smell of gas.

I'm making sure for you.

Your canister is a bit leaking.

Just check and replace it in the engine compartment and solve the problem.

In the engine compartment at the front of the car, there are a lot of wiring and plastic parts. When the car heats up, these parts emit some burning odor. Over time, the burnt smell will gradually subside.

In addition, brake pad friction and clutch slippage will also produce a burnt smell, when the handbrake is not completely lowered, during driving, the brake pads will keep rubbing, which will produce a burnt smell; When the clutch is not fully lifted, the car is in a semi-clutch state, when the throttle is increased, the clutch plate will rub against the flywheel quickly, resulting in a burnt smell, if the slippage is serious, the taste may take more than ten days to disappear.

If the smell of burn on the head is particularly large, it needs to be checked, and it is likely to be caused by the aging of the electrical circuit or oil circuit in the engine compartment. The aging of the oil circuit in the engine compartment can easily cause circuit failure and even cause spontaneous combustion of the car.

The wiring harness protector needs to be maintained regularly in the computer room, which is a relatively common maintenance method, and the price of the wiring harness protector is very cheap, so don't be greedy for trouble or saving money.

It should be noted that if you smell the smell of mixed combustion of engine oil and gasoline, the reason may be that the engine oil jumps into the cylinder chamber to participate in combustion, because the ignition point of engine oil and gasoline is different, so when the engine oil cannot be completely burned in the cylinder, a small amount of oil will be discharged from the exhaust pipe, that is, blue smoke. This blue smoke is definitely not normal. Normally, the oil in the oil duct only lubricates the cylinder wall and piston, but once the cylinder bore is severely worn or the piston is severely worn, the oil that was originally in the oil duct may jump into the engine combustion chamber.

In addition, engines with severe valve wear can also burn oil.

In addition, whether it is an EFI car or a carburetor vehicle, the fuel pipeline may deteriorate and crack after a long period of use, and as long as there is a slight bump or a change in the pressure in the pipeline, the fuel may leak out of these parts. Some vehicles have aging and leaking oil pipelines, which may also allow the oil to drip onto the engine or exhaust pipe, and then smell the smell of the engine oil may cause a disaster.

This is generally the smell of anti-corrosion paint and oil stains on the surface of the engine after being heated, if your car is a new car, this situation will be more obvious, but this does not mean that the vehicle is out of order, as long as the new car is used for a period of time, this smell will disappear by itself. Secondly, if there is a mushy smell in the engine compartment after the vehicle is uphill, then it may be caused by the high temperature of the transmission clutch plates, and we should avoid stepping on the accelerator when going uphill, so as to avoid the clutch plates burning out.

This is very normal, because the smell is not easy to volatilize so easily, so this situation occurs, and it may also be caused by some internal problems.

When people are driving a car, they are very afraid of what will happen to their car, especially on the highway, if there is a problem, it will be a serious traffic accident. Some people will report that their car will suddenly smell a burning smell after driving for a certain period of time, so when they smell this burning smell, they must be very panicked and very scared.

What's going on with the scorching smell, so today we're going to talk about what the burning smell is, or what's wrong with your car. So when we smell other abnormal smells on the car while driving, we must have a rough judgment in our hearts。When we are sure that there is no danger ahead, we can choose to pull the car to the side to avoid a major accident.

Or if there is something wrong with the car while driving, we can carefully smell whether it is the smell of gasoline or burnt smell, if it smells of gasoline, then we must not be driving the car forward, and there is a high probability that the oil pumped out of the gasoline leaks to the oil pipe. There is also another possibility, that is, we smell this smelly glue, it is not emitted by our own car, but the smell from the outside enters the car.

In the other case, we don't care about this situation, or if you can't tell whether it's your own car or the outside, we just need to lower the window and smell the outside. If there is no outside, then it means that your car has a burning smell, then we need to stop and check at this time. At this time, if it is the burning smell emitted from our car, it may be caused by a plastic bag stuck to the exhaust pipe of our car, then we only need to get out of the car and scrape off the plastic bag.

Be cautious, but if you smell this smell, it is recommended to get out of the car immediately and carefully check whether there is any problem with your car, if there is, send it to the car maintenance station in time to check or call the fire **, you can solve it immediately. This gives you peace of mind, as well as that of those around you

This is part of the passage and pipeline of the engine and gearbox during the driving process of the vehicle, which will be stained with oil for various reasons, and the smell of burning will be emitted when it encounters high temperature during driving, and it will automatically disappear after a short time.

It is very likely that there is a burning wiring in your car engine, so it will smell a burning smell when you drive, or it may be caused by excessive temperature.

It is because there is a problem with the brake pads when the car is driving, so there is a smell of burnt smell from the brake pads.

1. Too much carbon accumulation in the throttle and air flowmeter.

Throttle and air flow meter are still relatively easy to get dirty, most of the current cars are electronic throttle, a little carbon deposit may affect it, too much carbon deposit on the throttle will cause the fuel pedal to be stuck, the power is seriously reduced, and the idle speed is unstable!

The air flow meter is dirty, resulting in the wrong air flow signal, and the air intake determines the amount of fuel injection, which directly leads to inaccurate fuel injection, not only the fuel consumption will increase, but the power is seriously insufficient.

2. There is a gasoline leak in the car.

You need to go to the repair shop or dealer to check as soon as possible, this situation is likely to be a problem with the oil circuit of the gasoline pump, but it is also possible that there is a problem at the interface, many models of gasoline pumps are under the rear seats, as long as you open the rear seats, open the cover of the gasoline pump can be easily observed.

If it is really a problem with the gasoline pump, then the gasoline smell will go directly into the cockpit, and the smell will be very strong.

3. There is too much carbon deposit in the cylinder combustion chamber and piston.

There is too much carbon in the combustion chamber of the cylinder, which will have a certain adsorption effect on gasoline. In addition, there is too much carbon deposit, most of which will be formed on the valve and piston ring, which indirectly causes insufficient cylinder pressure.

There may be many reasons for the unstable idling speed of the car, such as vacuum leakage, spark plug breakage, etc., but the above problems occur after running one or two thousand kilometers, it is definitely not a broken part, it may be that the maintenance is not thorough.

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

The rubber pipes in the engine compartment will deteriorate after long-term use, and once they are aged, gasoline may leak out, which is generally the case in older models. The solution is also very simple, only need to replace the aging rubber tube.

5. There is residue when disassembling and assembling the gasoline pump.

Disassembling and assembling the gasoline pump needs to be completed in the car, and it is inevitable that there will be some residues in this process, if it is not cleaned up, it is possible to smell gasoline in the process of using the car. The solution is to go back to the repair shop to check that the petrol pump is installed correctly and that the surrounding area needs further cleaning.

There are several possible scenarios for this to occur:

1. Whether the engine oil is burned, you can observe for a period of time to see if the engine oil is lost or there is blue smoke.

2 may be caused by excessive oil volume, whether your car is more fuel-efficient than before, whether the start is smooth, if it is this reason, you can check the throttle, go to the repair shop to clean it or replace it.

The problem of the oil return pipe, the oil pressure is high, the work is more balanced, and after the fire is turned off, the pressure cannot come down.

The smell of gasoline must be that the gasoline is exposed to the air, so there are only a few possibilities:

1. Oil leakage, depending on your situation, the probability of oil leakage from the chassis oil pipe is relatively large, but if there is oil leakage, you can park the car in the cement open space first, start, step on the accelerator to 2000 rpm, turn off the engine after three minutes, get out of the car, and see if there will be gasoline dripping from the sound of the car.

2. The gasoline tank cap is not covered, or the seal is not tight, resulting in volatile gasoline emitting.

3. The upper part of the gasoline tank is damaged due to the loosening of the fixing screws, resulting in long-term friction with the body, resulting in the smell of gasoline.
