The exhaust pipe is dripping! Just proof that your engine is in good shape!

Winter is coming.

Many people find that

New or old

Luxury car or regular car

The exhaust pipes all seem to be dripping

Before starting the vehicle

There's already a puddle of water under the exhaust pipe

Owners who don't know the truth may struggle

Is there something wrong with the exhaust pipe?

Is there something wrong with the engine?

Is there water in the oil?

Don't panic, don't panic

A dripping tailpipe is not necessarily a bad thing

Let's listen to Xiaobang tell us

Exhaust pipe dripping, normal operation

Dripping water from the exhaust pipe during driving is a manifestation of complete combustion of gasoline in the engine.

So don't worry, it's not a problem.

Especially in winter, we see that the white smoke from the exhaust cylinder is water vapor, and when the water vapor passes through the cold and cold exhaust cylinder, it will condense into small water droplets, which will flow out from the exhaust cylinder.

In order to let the water flow out of the exhaust pipe smoothly, the exhaust pipe of the car is generally designed with a small hole, the purpose is to drain water.

Different models are designed in different locations, and generally manufacturers will choose the lowest position in the tail or middle to let the water drain out.

So the car exhaust pipe dripping is a normal phenomenon, which shows that the engine gasoline combustion is more full, the engine atomization effect is also better. In the winter, you can see that if the exhaust gas from the exhaust pipe of the car has fog, the engine is in good condition.

How to tell if it is normal dripping?

Engine dripping is generally a normal phenomenon, but there are exceptions, if your car has the following conditions, it is an abnormal phenomenon:

A lot of white smoke

Some small partners may find that when the vehicle is just started, the exhaust pipe will have white smoke accompanied by liquid spray together, do not worry about this, this is water, indicating that the combustion of the engine is very good. But if it's a lot of white smoke, be aware.

There are probably two reasons for more white smoke: first, there is too much water in gasoline; Second, the sealing pad of the waterway is broken, and the cooling water enters the cylinder.

Milky white oil mist

If you find that the exhaust gas emitted is a milky oil mist, which will coagulate on the ground, it is likely that the fuel is not vaporized well.

Mainly because the temperature is too low and the fuel atomization is poor, it usually disappears after the engine starts with the engine temperature rising.

Discharge black fluid

If the liquid from the exhaust pipe is black, and very sticky, but also accompanied by blue smoke, the oil consumption is very fast, the engine power is obviously insufficient.

This situation shows that the gap between the piston, cylinder liner and piston ring of the engine is too large and can no longer work normally, which needs to be checked and maintained in the repair shop.

Excessive dripping

Although the car exhaust water reflects the performance of the car, it is not the more the better.

On the one hand, too much water in the exhaust cylinder will damage the oxygen sensor in the three-way catalytic converter, resulting in inaccurate engine oil supply and affecting the performance of the car.

On the other hand, water droplets staying in the exhaust pipe for a long time will also accelerate pipe corrosion. Therefore, if you find that your car's exhaust pipe has rust spots, it is recommended to check whether the small opening of the exhaust cylinder is blocked and clean it up in time.

After reading the above content, we should all know that the exhaust pipe dripping is a normal phenomenon, but also pay attention to the usual maintenance; After all, the winter car is a high risk of failure, change the oil, antifreeze, check the tires, these are need to be done in the winter maintenance.
