What is the reason why new energy vehicles have a burning smell after running 40,000 kilometers?

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.

Hello, the hybrid electric car ran 10,000 kilometers. There is a burning smell for the following reasons:

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 for inspection to determine that the smell is **, is it 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.

Hope it helps!

First look at the exhaust pipe for sticky things, rule out external factors, and then check the engine compartment.

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.

1. The clutch plate will produce a scorching smell in a long-term semi-linkage state, and it will also produce a scorching smell 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.

2. Semi-linkage is the state that the clutch is between the clutch and the connection, and the transmission system is between the connection and the non-connection, which can provide a flexible power and will be often used in some complex road conditions and starting, turning and short-distance follow-up.

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

The reason for the mildew is that water vapor and mold accumulate on the indoor heat exchanger of the air conditioner, and the mildew cannot completely evaporate to form mildew, and the mildew will appear in a period of time after a long time.

Here's how to deal with it simply:

1.Change the current way of use: the heat exchanger is moldy and has a lot to do with use, because it is normal for water vapor to condense during refrigeration, but after the shutdown, we must pay attention to ventilation to keep the air conditioner heat dissipation smooth, and it is best not to cover the air conditioner, and treat the aging appearance of the air conditioner.

2.It is recommended to remove the air conditioner filter and gently brush the inner fins with a soft-bristled brush with a detergent to remove mold on the surface.

1. This is a normal phenomenon, and there is no need to worry, because of the burning smell caused by the friction of the new tires.

2. Daily maintenance of the car: daily maintenance is daily maintenance, which is the operation before leaving the car, during the driving and after the car, which is carried out by the driver, and the content of the operation center is cleaning, supply and safety inspection, which is a regular and necessary work to maintain the normal working condition of the vehicle. The first-level maintenance is carried out by a professional maintenance company, and the content of the operation center is mainly cleaned, lubricated and fastened in addition to daily maintenance operations, and the safety components such as braking and manipulation are checked.

The secondary maintenance is carried out by the professional maintenance enterprise, and the content of the operation center is mainly inspected and adjusted in addition to the first-level maintenance operation, and the tires are dismantled and inspected, and the tires are transposed. Before the secondary maintenance, the detection and diagnosis and technical assessment should be carried out, and according to the results, the additional operations or minor repair items should be determined, and the secondary maintenance should be carried out together. The interval of maintenance at all levels depends on the type of vehicle and operating conditions.

3. Regularly inspect the car:

1) Check the liquid level height of the battery with a test tube with a diameter of 5 n 6mm, from the liquid filling port to the vertical force to contact with the filter screen, close the upper end of the test tube with your thumb, lift the tube, and measure the height of the liquid column is the liquid level height of the battery, the standard should be 10 n 15mm.

2) Check the height of the lubricating oil level, take out the oil dipstick when cold driving, wipe it clean, insert it into the bottom of the oil pan, and observe that its height should be between the upper and lower markings. When the car is hot, the engine should be turned off, and the oil should be measured after all the oil has flowed into the oil pan.

3) Check the height of the coolant level, the coolant in the water tank should be full when the car is cooled, and the height of the liquid level in the expansion tank should be between the markings. The liquid level height should be slightly higher than the superscript when the car is warmed.

4) Check the height of the brake fluid and steering fluid, unscrew the bolt, and directly observe whether the liquid level is within the specified marking range.

5) Check the quality of the oil.

The smell of burning in the new car is mostly caused by the poor fit of the oil, so practice more.

Hello. In this case, it is recommended to focus on checking whether there is any oil leakage in the connecting lines and whether the temperature of the engine is too high.
