The car has run 20,000 kilometers, what is the reason for the smell of burning?

The clutch plate will have a burning smell when it is semi-synchronized for a long time, and it will also have a burning smell when driving when the parking brake cannot be released. If the oil changes fall on the engine block, the oil will evaporate when the engine is hot, and a burnt smell will occur.

Actually, this is not easy to judge, you have to determine where the burnt smell came from? And then where to focus on checking?

This situation needs to be checked for the burnt taste, and then see what measures are taken to solve it; If you can't find it yourself, it's best to go to the place where the car is repaired and have it checked.

Hello, in this case you need to go to the 4S store in time.

1.The smell of burnt smell is not emitted by the car itself, but by the smell of the outside world entering the car. This situation is very common, many people have encountered it, and sometimes they suddenly smell a foul smell, which is also transmitted into the car from the outside world.

This is a good judgment, first lower the window for ventilation, smell the outside air if there is a burnt smell, continue to drive forward for a certain distance before closing the window. If there is no smell, it means that it is not from the car, if there is still a smell, it means that it is from the car somewhere, at this time it is necessary to stop and check to determine whether the smell is sent out and whether it is serious.

2.If it is the burnt smell of your own car, the most common situation you encounter is caused by plastic bags sticking to the exhaust pipe. There is that kind of thin plastic bag on the road, and the vehicle rides it over, because the exhaust pipe is very hot, the plastic bag will melt and stick to the exhaust pipe when it touches it, and then continue to melt, emitting a burnt smell of burning plastic.

Although the source of this smell is at the bottom of the vehicle, it can be found all around the vehicle, and when you enter the car through the air conditioning intake, you will smell a strong smell of burning. So if you feel that the smell is strong, find a safe place to stop the car and lie down first to see if there is anything on the exhaust pipe. It is generally in the front or middle of the exhaust pipe, and a small number of cars are in the rear of the exhaust pipe.

As soon as I smell the smell, I check it, and at this time the plastic bag has not completely melted and can be seen at a glance.

3.Pull the handbrake to drive, and the handbrake pads grind out a burnt smell, which is improper operation and abnormal driving. If the handbrake is not loosened, the handbrake pad has been in a state of friction, and the friction will produce a lot of heat, and if the heat is too high, the handbrake pad will be burned and the smell will be produced, and even the handbrake pad will be scrapped directly.

It generally appears on automatic transmission cars, and it is a novice driver, and it does not appear very often. At this time, not only is there a burnt smell, but there will always be an alarm sound in the car, and the car is very heavy, there will be a variety of prompts and performances, and it is easier to find this error.

4.The manual transmission car smelled burnt after starting on a big slope, which didn't need to be checked too much, it must have been emitted by the clutch plates. Starting on a large slope, the throttle added in the semi-clutch state is very large, and the clutch is loose very slowly or not completely released, there will be violent friction between the clutch plate and the flywheel, resulting in a high-temperature burnt clutch plate odor.

The vast majority of people in this situation are novice drivers, of course, once in a while, the clutch plate will not be too damaged, and the burnt is only the shallow surface of the clutch plate. If you feel abnormal at the start, the clutch plate may have been damaged and needs to be replaced. And the clutch plate is not warranted, I once encountered a new car in this situation, and asked if it can be guaranteed.

The answer is no, any damage to any part caused by human causes is not warranted.

5.Smell from an oil leak somewhere in the engine and oil dripping onto the exhaust pipe.

Burnt taste**.

1. It is the car and its surroundings that have the conditions to produce this smell.

2. It is you who have started the outer circulation.

1) For new cars.

It is normal for a new car to have this smell, and all kinds of rubber and plastic parts of the new car are new, and this smell will be produced at high temperatures, and it will slowly fade to the point where it cannot be smelled.

2) Someone is burning something next to the car.

If there are rubber and plastic products, it is possible to produce this kind of national arrival, and then enter the car through the outer circulation.

3) The smell of gasoline is mistaken for the smell of burning rubber (insufficient combustion).

For example, when starting a car in winter, due to the low temperature, it increases the difficulty of gasoline commissioning, which affects combustion, and some of the unburned gasoline molecules are discharged through the exhaust pipe and then enter the car through the external circulation.

4) The smell of brake pad friction.

For example, sometimes the handbrake is not completely lowered, and you keep rubbing the brake pads when you drive it, which will produce a metallic burnt smell. Or some of the brake pads have large metal particles, and when these metal particles are to be worn out, this kind of burning smell will be produced for a short time.

5) The burnt smell of the clutch plates.

The clutch plate of the gearbox slips, causing high temperatures, and it will also produce that burnt smell, and it may take 10 days for a severe slip to produce a smell that is completely unsmellable. When you increase the throttle uphill, the clutch plate and flywheel are quickly motorized, and the smell of burnt is generated, there is no problem with a short time, if the large throttle is half clutch for a long time, the clutch plate is easy to burn. Then it's time to replace the clutch plates.

6) The exhaust pipe scraped the plastic bag.

The temperature of the exhaust pipe is very high while driving, and if a plastic bag sticks, it will cause the plastic bag to melt and produce a smell of burnt rubber.

Other aspects mean hidden dangers.

Abnormal gasoline smell: oil leakage from the fuel tank or suspected failure of the fuel supply system.

If the car is driven for a long time, the oil pipeline may undergo aging electric cracking, and if it encounters a special competitive road section, it is likely to cause the pressure in the pipeline to change, and the gasoline will leak out.

The air conditioner has an odor: The air supply channel or filter element of the air conditioner needs to be cleaned.

In fact, in addition to regularly replacing the air conditioner filter, we also need to pay attention to some details, that is, to clean the air supply channel, foot pads and other pollution sources that are easy to ignore.

Consider oil stains on the exhaust pipe, oil leakage from the engine, aging or short circuits in the car
