The car is composed of tens of thousands of parts combined together, and the large machine parts run into each other so that the car can run normally. The old driver of the train can judge whether the car is healthy by observing the operation of the parts, and a small exhaust pipe can also expose the big problem.
In winter, the temperature is relatively low, and some car owners find that the exhaust pipe is abnormal, always dripping water or white smoke for no reason. The exhaust pipe drip of a car in winter exposes a signal that if the owner leaves the vehicle alone, there could be a big problem.
The principle of exhaust pipe dripping:
The drip from the exhaust pipe may be due to insufficient combustion of gasoline, or it may be that some moisture has been mixed into the gasoline. Gasoline, when burned by the engine, generates water and carbon dioxide, which are emitted through the exhaust pipes.
In winter, the temperature is low, and the water vapor emitted by the exhaust pipe condenses into water when it encounters cold air. Some cars have too much exhaust, and a large amount of water vapor condenses into water and then drips down the exhaust pipe.
Is a lot of dripping from the exhaust pipe good or bad?
Occasional dripping of the exhaust pipe is a normal phenomenon, we do not have to pay attention to it, if the drip of the exhaust pipe suddenly increases, the owner should be wary of possible problems with the engine. During the normal operation of the vehicle, a large amount of air will enter the cylinder, and gasoline can only burn normally after mixing with air.
Some cars have engine problems, gasoline burns sufficiently, or the gasoline atomization effect is good, which will cause the exhaust pipe to produce more and more water. Some old drivers think that the exhaust pipe dripping is a good phenomenon, the more gasoline burns, the more water drips, this statement is completely untenable.
The exhaust pipe drip can indeed reflect the good atomization effect of gasoline and the full combustion of gasoline, but too much dripping indicates that some parts on the car are damaged. If the owner finds that the vehicle's winter dripping water is very abnormal, he can check whether there is a problem with the oxygen sensor in the three-way catalytic converter.
Hazards of large dripping water in the exhaust pipe:
The water flowing out of the exhaust pipe is not pure water and may have some corrosive liquid in it. Increased drip volume of the exhaust pipe will lead to serious corrosion of the pipeline, and the owner needs to check whether there is a problem with the exhaust pipe.
If the water dripping from the exhaust pipe is not pure, there is some black substance in it, indicating that there is a problem with the engine. The owner of the car can drive the car to the repair shop to check whether the piston steel sleeve of the engine has the problem of excessive voids, and eliminate the hidden dangers in time.
Some car owners find that the exhaust pipe of German cars is easy to drip, and Japanese cars are not easy, so they think that German cars are more powerful than Japanese cars. The power of the car is related to the engine displacement, and the power of the car is not in line with the basis for judging the drip of the exhaust pipe.
Editor's Comments:
Dripping from the exhaust pipe in winter is a normal phenomenon, indicating that gasoline is fully burned and the atomization effect is good. However, when we find that the exhaust pipe drip is abnormal, we should also pay attention to it, and the exhaust pipe of some cars has been emitting black smoke and accompanied by dripping water, which means that there is a problem with the engine.
If you want to improve the problem of dripping water from the exhaust pipe, you can add fuel treasure or use higher quality gasoline, and it is normal for the vehicle to discharge white smoke from the tail during normal driving. If the smoke emitted by the car turns blue, it means that the car may have more carbon deposits. If black smoke comes out of the rear of the car, it means that there is a big problem with the engine, and it must be checked as soon as possible.
