It s only 100,000 kilometers, and the exhaust is smoking?

There are several situations of exhaust smoke:

1. If it is black smoke, it means that the mixture is too thick, which is a manifestation of insufficient combustion.

Several ways to solve the problem: clean the throttle, fuel injector, intake tract; Match the data of the driving computer; The gasoline added is not very pure, try adding a higher grade gasoline.

2. If it is white smoke: this means that there is a small amount of water in the cylinder, which becomes white gas and is discharged after combustion.

Cause of the problem and solution: It may be that the cylinder gasket between the engine cylinder head and the cylinder block is broken down (easy to break down at high temperatures), and the cylinder gasket can be replaced.

3. If it is blue smoke: this is the manifestation of burning engine oil, the cause of the problem and the solution: Generally, when the car is long or the number of kilometers is more than 100,000, there will be a situation, and the parts related to burning engine oil are generally

Valve seals, valve guides, cylinder liners, piston rings, pistons, etc., can be disassembled at the repair shop to check the damaged parts, and then replaced.

Tips: If you find light smoke around the engine cover when driving, it may be that the engine water temperature is too high, and the pot is boiling!! Here is a reminder that you need to pay more attention to the water temperature when driving in summer, if the water temperature is too high, it will accelerate wear and shorten the normal service life of the engine.

Obviously burn the engine oil!

Now the engine burns oil so heavily for 100,000 kilometers, it is really rare, go to the repair shop to see, this kind of problem is more troublesome to repair.

It's normal for cars to smoke from their exhaust fumes, but what kind of smoke is better? It is estimated that many owners will not know too much, so what kind of smoke will be emitted from the general exhaust? What kind of cigarette do you usually smoke? Let's find out.

The normal state of smoke is slightly transparent smoke, which is a healthy car exhaust. If you find white, black, or blue smoke, pay attention. Like white smoke, it may be that there is a problem with the engine floor pad, and there are gaps that cause the engine to be unstable.

Please check it out. As for the low-temperature hot car, there is occasional white smoke, which can also be ignored.

As for the black smoke, it is most likely caused by insufficient fuel burning. If the short beat goes on for a long time, it will lead to carbon deposition in the engine. Over time, it will cause a decrease in engine power and high fuel consumption, so you should also pay attention.

Cases like blue smoke are rare, which means that an internal engine failure can cause oil to escape into the combustion chamber, causing the oil to burn, and engine failure will be more difficult. Of course, if too much oil is added, this phenomenon may also be caused. Exhaust emissions can simply cause some problems for the car, so it is important to check the color of the exhaust emissions.

If some newbies don't know, they really need to stop this from knowing.

Millions of car purchase subsidies.

We often encounter smoke from the exhaust pipe when driving on the road, and some novice drivers don't understand, so it's easy to be at a loss, thinking that the car is out of order. Although smoke is a cause for concern, there are also points where different colors of smoke represent different symptoms.

The most common exhaust colors are white, blue and black. First of all, the white exhaust gas, which means that the engine fuel is fully combusted, and the white smoke will disappear quickly, sometimes accompanied by water droplets, which proves that the engine is healthy and normal. Because the combustible mixture enters the engine cylinder and burns, carbon dioxide is produced.

and water, which eventually passes through a three-way catalytic converter.

The muffler and exhaust pipe will condense into liquid water, so sometimes the exhaust pipe will drip water. When the temperature is relatively low, such as winter, due to the physical effect, the exhaust pipe will appear "white smoke".

White smoke from the exhaust during cold starting, and the white smoke disappears after the engine warms up, it should be regarded as normal, if the vehicle emits a large amount of white smoke during normal operation, it is necessary to go to the repair shop to replace the gasket. That may be because the cylinder head is not tightly sealed, and a large amount of engine heat flows out, which makes the exhaust pipe temperature too high, and the water and carbon dioxide in the exhaust do not condense into water droplets and are directly discharged.

Secondly, for the exhaust pipe that emits blue smoke, there is basically engine oil burning.

may be because of the spark plug.

The gap with the cylinder is too large, the oil seal is aging, and so on. It is recommended to check whether the engine cylinder seal is damaged, and change the oil with higher viscosity, otherwise it will weaken the power, increase fuel consumption and even pull the cylinder over time.

phenomenon. Finally, it is the most important one to pay attention to, that is, black smoke from the exhaust pipe, like tractor smoke, which is generally due to insufficient combustion of gasoline, resulting in carbon accumulation in the engine.

If the engine shakes severely, the exhaust pipe not only emits black smoke but also makes abnormal sounds, and the acceleration is weak. Then we need to go to the repair shop to check the spark plug and oxygen sensor.

as well as air flow meter lamp methods to troubleshoot.

If this phenomenon occurs, the main reason is that the engine burns badly, there may be a problem with the spark plug, a problem with the ignition coil, and it may be that there is more moisture in the gasoline in this home. The engine burns badly, and this phenomenon occurs. As long as the landlord is not missing a book that does not show that the temperature of the engine is relatively high, and the power is normal, it will automatically disappear after driving a few kilometers, this will not have any guanlu chain system, there is no impact, and you can use it with confidence.

In this issue, we will share with you what causes car exhaust smoke, and teach you to judge what is wrong with your car by the color of exhaust smoke, let's take a look!

If it is winter, it may be because the temperature is low, and the exhaust gas from the engine condenses at low temperatures to produce water vapor, which will produce a large amount of misty white smoke. This situation is normal, just heat up the car. If the temperature is normal, then it is possible that the piston of the engine is broken, or the cylinder liner is broken, and the engine is burning oil.

It is also possible that the water in the coolant has entered the cylinder, check if the amount of coolant is normal, and see if the coolant gasket is broken. In addition, it has something to do with the gasoline added, whether it is inferior gasoline, and there is too much moisture in the gasoline. According to the displacement and idle speed of their own cars, the idle speed is high, the more gasoline is burned, the more water vapor will be, the exhaust volume is large, the three-way catalytic mesh is large, and the water vapor is more. ‍‍
