What s wrong with dripping exhaust pipes in winter, and why does car exhaust pipes drip in winter

Dripping water from the exhaust pipe is a normal phenomenon in winter. When gasoline is completely burned, water and carbon dioxide are produced. Water is steam in a high-temperature environment, but when it encounters a cooler exhaust pipe, the steam will condense to form liquid water, so the exhaust pipe of some cars will drip in winter.

It is normal for the exhaust pipe to drip and there is no need to worry.

Some people will tell if the engine is burning enough by looking at the exhaust pipe to see if it is dripping, but this is actually wrong.

If the exhaust pipe temperature is too high, the exhaust pipe will not drip even if the engine burns completely.

If the exhaust pipe temperature is very low, the exhaust pipe will drip even if the engine does not burn sufficiently.

So don't tell if a car engine is burning enough by looking at the exhaust pipe to see if it's dripping.

When you usually use the car, as long as you maintain it on time, there is no problem with the engine.

If the incorrect gasoline label is selected, it can affect the power of the engine and can also cause engine knocking.

Severe knocking can even cause engine connecting rods to deform or pistons**.

Normally, gasoline is burned to produce carbon dioxide and water vapor, and the water vapor condenses to form liquid water, which is discharged through the exhaust pipe.

This is a very normal phenomenon, don't panic, gasoline after safe combustion produces carbon dioxide and water vapor, water vapor condenses to form liquid water, and when it reaches a certain amount, it is discharged through the exhaust pipe.

This is related to the factory design of the car The exhaust pipe generally has a small hole, which is used for drainage, and the rear of the tail design of some exhaust pipes is relatively low, so that the water will be discharged during driving, which is why the exhaust pipe of the car in front of you can see the water dripping outward, and the middle of the exhaust pipe is relatively low, and the manufacturer will punch a hole in the lowest place in the middle to let the water be discharged.

Dripping water from the exhaust pipe of a car in winter is a manifestation of full combustion of gasoline.

The exhaust pipe of the automobile engine sometimes discharges water to the outside, especially in winter, which makes people mistakenly believe that the cooling system is poor and there is a leakage problem, but in fact this is a very normal physical phenomenon, and it is also a manifestation of full combustion of gasoline.

The principle of gasoline combustion:

1. The main component of gasoline is C4 -C12 hydrocarbons, which are mixed hydrocarbons, and their composition is relatively complex.

2. After gasoline combustion, carbon dioxide, water and a small amount of carbon monoxide are mainly produced, and the carbon monoxide in the exhaust gas will react with oxygen again in the three-way catalytic converter to become non-toxic carbon dioxide and then discharged.

3. Every 1 kilogram of gasoline mixed with air is burned to produce about kilograms of water, which is mainly discharged into the atmosphere in the form of vapor.

Gasoline combustion of liquid water formation:

1. When the engine is working, the gas discharged from the cylinder reaches 400-800 or even higher, and the water generated by combustion is vapor.

2. The temperature of the exhaust system is low in the engine warm-up stage, and the vapor water in the exhaust gas will condense, and a large amount of water will adsorb the exhaust pipe wall with relatively low temperature.

3. As the temperature of the exhaust system increases, the water in the exhaust gas will be discharged in the form of vapor, which is invisible to the naked eye.

4. If the outside temperature is low, the discharged vapor water will condense in the air and will appear in the form of fog, that is, the common white fog phenomenon at the exhaust pipe mouth.

Hello. This is normal, indicating that the combustion is sufficient. The composition of gasoline is hydrocarbons, so gasoline produces moisture when burned.

Due to the high temperature of the engine, the water will turn into water vapor, and when the exhaust gas is discharged to the exhaust pipe mouth, it will condense into small droplets when it is cold, and part of it will remain in the exhaust pipe, so the exhaust pipe of many cars will be designed with a drain outlet. The more winter it is, the more obvious it is, and you can clearly see the dripping water. This means that the engine burns sufficiently, and if the exhaust pipe of a car does not drain in winter, it means that the engine burns poorly.

Hello: The exhaust gas of the engine contains water vapor, which will condense into small water droplets when cold, which will gather from the exhaust pipe and be discharged under the action of exhaust power when refueling. In winter, the temperature is low, and it is more suitable for condensation, so it is normal for the exhaust pipe to drip in winter, so there is no need to worry.

Have a nice job.

Normally, after the gas oil is burned, it is water and carbon monoxide, the exhaust pipe is cold, and the water forms water vapor in the exhaust pipe, and more small water droplets are discharged.

Hello, this is normal, the exhaust pipe is hot, and the air outside is cold, so it will drip water, and it will not be normal if it does not drip water.

After three-way catalysis, automobile exhaust gas is reacted into carbon dioxide, nitrogen, and water vapor. It is normal for water vapor and cold to turn into water.

It is a good phenomenon that the exhaust pipe of the car is dripping, which proves that the fuel has been fully burned in the engine, and the exhaust pipe of the car will drip outward, which is actually a very normal phenomenon. The reason why the exhaust pipe drips is because the ambient temperature is relatively low, and the gasoline is completely burned to produce water and carbon dioxide.

Water at high temperature is the result of water vapor, water vapor condensation in the exhaust pipe and muffler, but when the ambient temperature is high, the water vapor has not yet condensed has been discharged, when the ambient temperature is low, the water vapor will condense into water droplets on the exhaust pipe wall, and flow out along the exhaust pipe.

Especially in winter, the external environment is relatively cold in winter, the air humidity is high, and the temperature difference between the inside and outside of the engine is large after the car is running, which is more likely to cause the phenomenon of water dripping from the exhaust pipe of the car. Many car owners may also see white smoke from the exhaust pipe when they encounter a lot of dripping water from the exhaust pipe of the car.

What's going on with the dripping water in the car exhaust pipe There's a lot of knowledge in it.

What to do if the car exhaust pipe drips: Many car owners may also see white smoke from the exhaust pipe when they encounter a lot of water dripping from the car exhaust pipe;

This is usually when a car parked in the winter or rainy season starts for the first time, but if the white smoke disappears once the engine temperature rises, there is no need to worry about this situation and there is no need to overhaul it.

If the exhaust pipe becomes black smoke after the engine temperature rises, it indicates that the cylinder pressure is too low or individual cylinders are not working, which should be checked and eliminated. When the engine is running, the exhaust pipe discharges a large amount of water vapor and white smoke, and it is necessary to check whether there is water in the fuel tank, check whether the cylinder gasket is damaged, whether the cylinder block is cracked, and whether the cylinder liner sealing ring is good.

If there is no smoke exhaust, it is simply just a dripping water from the exhaust pipe, which is mainly because the gasoline is completely burned to produce water and carbon dioxide, water is water vapor at high temperature, and water vapor is colorless and transparent at high temperature, but when the temperature is lower than 100, the water vapor will condense into water, if the condensed water droplets are small and suspended in the air, the water vapor will appear as white gas, and when the ambient temperature is low, the white smoke from the exhaust pipe is water vapor;

If condensed water droplets accumulate, it becomes water. The water droplets discharged from the exhaust pipe are the result of condensation of the water vapor generated after the combustion of gasoline in the exhaust pipe and muffler, but when the ambient temperature is high, the water vapor has not yet condensed and has been discharged, and when the ambient temperature is low, the water vapor will condense into water droplets on the exhaust pipe wall, and flow out with the exhaust. This phenomenon is prevalent in cars with good engine work.

Hello, this is a normal vehicle combustion will have water vapor discharge, so that it will produce water droplets when it is cold, and it is normal to drop water this winter.

In winter, the exhaust pipe dripping is normal.

The exhaust gas of the engine contains water vapor, which condenses into small water droplets when cold, which collects from the exhaust pipe and is discharged under the action of exhaust power when refueling. In winter, the temperature is low, and it is more suitable for condensation, so it is normal for the exhaust pipe to drip in winter.

The exhaust pipe is a part of the engine exhaust system, the exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler, generally to control the emission of engine pollutants The three-school catalytic converter is also installed in the exhaust system, and the exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe.

But there is one thing to be aware of: when the tank leaks, there may be a puddle of water left on the ground! Check the auxiliary kettle, and if there is significantly less water, use the leak protectant of the Limo water tank immediately!

Shake the product directly into the auxiliary kettle when cooling the car, and then start the vehicle to idle for 10 minutes, and the pants can reliably seal the slightest leaks in various parts of the cooling system.

Exhaust pipe

In order to reduce vibration and noise, facilitate installation and prolong the life of the exhaust muffler system, the exhaust pipe is installed between the engine exhaust manifold and the muffler, so that the entire exhaust system is flexibly connected.

The exhaust pipe is mainly used for light vehicles, mini cars and buses, motorcycles, and the exhaust pipe structure is a double-layer bellows covered with steel wire mesh sleeve, and the structure of the jacket ring at both ends of the straight edge section. The main material of the exhaust pipe is stainless steel, and the ferrule and pipe can be made of stainless steel or aluminized steel.

<> "It is normal for the exhaust pipe to drip in winter, because the temperature is relatively low, the water generated by the three-way catalytic converter will evaporate into water vapor, but the low temperature will turn the water vapor into water, so it will drip out. We don't need to worry about this situation, it's a normal reaction situation.

What else will drip water.

1. Water may also drip when the air conditioner is turned on, but this situation is the water leaking from the chassis of the car. There will be a lot of water vapor in the air, and the water vapor will become water when it reaches the air conditioning evaporation box, and the air conditioning water outlet is under the chassis of the car, so we will find that the chassis is dripping, which is normal;

2. It will drip after rain or after washing the car. There will be a lot of drainage holes in the car, and the water in the car or on the body will go out through these small drainage holes after washing the car or raining, so there is no need to worry about it at this time.

What is dripping is not normal.

The situations mentioned above don't actually have any impact on the car, they are relatively normal situations, and we don't need to worry about them. However, if the water flowing out of the car is not clean water, and the burning reeds are colored or smelly, then we need to pay attention, and it is likely that all kinds of oil are leaking out.

After the oil leaks, if we don't pay attention, the oil inside the car is getting less and less, these are to lubricate the auto parts, there is no oil there is not enough lubrication, it will lead to damage to the parts during the driving process, so the oil leakage needs us to go to the repair shop for maintenance.

<> "Hello dear, it's normal for the exhaust pipe to drip in winter. During the normal combustion process of automobiles, carbon dioxide and water vapor will be produced, and the water vapor condenses to form liquid smile-sensitive water. When the amount of water vapor reaches a certain level, it will be discharged through the exhaust pipe to destroy the outside of the vehicle.

When some car companies design the exhaust pipe, there are drainage holes in the exhaust pipe, and water can be discharged to the outside of the car through the drainage holes. This dripping is normal when the water dripping from the exhaust pipe agglomerates on the ground and the exhaust gas is a milky white oil mist. It is necessary to check whether the water in the engine cooling water tank is abnormal.
