Why is the exhaust cylinder leaking in the Lechi car?

When there is a lot of dripping water from the exhaust pipe of the car, you may also see white smoke from the 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.

That's because when the ambient temperature is relatively low, especially in winter, the exhaust pipe of the car will drip outward, which is actually a very normal phenomenon. It is because the gasoline is completely burned after the generation of water and carbon dioxide, water is water vapor at high temperature, water vapor is colorless and transparent at high temperature, but when the temperature is lower than 100, water vapor will condense into water, if the condensed water droplets are small and suspended in the air, water vapor will appear as white gas, when the ambient temperature is low, 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.

If the cylinder gasket leaks, it should enter the exhaust pipe, and the water will enter the cylinder from the waterway and then enter the exhaust pipe from the exhaust valve.

If the water is clean, it is normal.

That's the muffler leak of the exhaust cylinder

Upstairs copy what he doesn't understand, I'll tell you it's normal, and besides, your engine burns very well, so there will be water. In the case of winter, cars with well-maintained engines will emit white smoke.

This can be broadly divided into two situations.

All cars will be equipped with a three-way catalytic converter when leaving the factory, which is a mandatory regulation of the state, and the three-way catalytic conversion is to convert carbon monoxide and nitric oxide in the exhaust into carbon dioxide and nitrogen (non-toxic, harmless and non-polluting), and the specific chemical equation is limited to the format can only be written as follows:

2NO+CO=(catalyst)=CO2+N2

The chemical reaction in this process is relatively strong, so it will cause vibration, and because the three-way catalytic converter is installed at the exhaust pipe mouth, it will cause the exhaust pipe to vibrate, which is more common in cold cars and new cars, and is a normal phenomenon.

The exhaust pipe is usually fastened with screws or snapped directly into the chassis. If the screws are not tightened, the exhaust tailpipe may vibrate; Similarly, the exhaust tailpipes that are clamped to the chassis can also cause vibrations due to falling off. In this case, all you need to do is tighten the screws that hold the exhaust pipe in place, or ask a professional to fix the exhaust pipe to the clip.

The Lechi should be fastened with screws, please indicate the type of Lechi you are buying. ）

Under normal circumstances, there is a running-in period for a new car, and it will be fine after a period of time, and there is also a situation where the fixing screws may not be tight, and there will be abnormal noise. It is recommended that you grope for it yourself to see if the exhaust pipe has the right to move, and if so, tighten it.

Maybe the drain is too big and the location is not good. It is normal to be able to drain water in a good and timely manner.

This is because the water vapor and carbon dioxide produced after the complete combustion of gasoline condenses into water when it is cold. The function of the drain is to drain the stagnant water in time, so as to protect the exhaust pipe from water corrosion and perforation, and prolong the life.

Hello, it is recommended to check whether the air intake pipe is aging, and the landlord can make a reference.

Remove the attachment attachment first, then remove the fixing wire thanks to this.

1. The temperature is not enough, due to the insufficient temperature of the engine, the mixed gas formed by the fuel and air injected into the cylinder cannot be burned partly, and the exhaust pipe emits white smoke. Therefore, after the locomotive starts, attention should be paid to the insulation of the water tank, and the middle throttle is used to run so that when the locomotive temperature reaches more than 50 degrees, the load is gradually increased.

2. There is water in the diesel and water in the diesel, which directly affects the normal combustion of the mixed gas and emits white smoke. At this time, the precipitated oil should be released, the stagnant water should be discharged, and the diesel fuel should be replaced if necessary.

3. If the exhaust pipe continues to emit white smoke, it may be that the cylinder head and cylinder gasket of individual cylinders are damaged and water is ingressive, so it should be removed for inspection and replaced with damaged cylinder heads and cylinder gaskets. In addition, if the intake valve is not closed tightly, white smoke can also appear, which should be inspected and repaired.

1 All you had better go to the 4S store for an inspection, what you said must be the water leaking in the back.

First, the rear window glass seal is loose.

Second, the taillights are loose.

Third, there is a gap in the rear window glass joint.

Fourth, the trunk went into the water during the car wash.

One is not the water that enters the car wash.

The second is that the gap between the back doors is large, and the water coming in.

The third is that there is a leakage in the rear tailgate glass.

Fourth, the trunk is connected to the rear row, have you let go of something with water in the trunk, and then it flows to the rear seat.

Wouldn't it be okay to drive it back and check it? is still under warranty, go back directly to him for trouble.

You're talking about water leaking from the outside into the car, right? Upstairs, I basically talked about the problem of being able to get water.

It's a little leaky, and there's a water blockage underneath the ground, so let's see if there's any problem with that water blockage.

Do you know why? Ours also leaks.

First, there may be no sealing ring at the interface of the raw material belt.

The second interface can be sealed with glass glue.

This is because when the engine of a car burns, it produces some water to be discharged from the exhaust pipe.

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

The products of complete combustion of gasoline are water and carbon dioxide, so dripping water is a normal phenomenon, indicating that the engine is in good condition.
