What s going on with the popping sound of the car exhaust pipe?

There are generally the following situations when the exhaust pipe has a popping sound, the first is that the muffler is partially leaking, ruptured or the interface gasket is damaged and the exhaust leakage leads to abnormal noise, and the engine working state is unstable resulting in the unbalanced work of the engine cylinder, resulting in the sound of the exhaust pipe popping, the exhaust is not coherent, and the cause of the failure needs to be analyzed according to the actual situation, and it is best to go to the repair shop to check it.

Whether the sound of the exhaust pipe popping is normal depends on the location and magnitude of the sound.

First: the so-called pop sound does not necessarily come from the exhaust pipe, first explain the exhaust pop sound, the sound of the exhaust pipe depends on two aspects, one is the material of the exhaust pipe and the sound of the exhaust pipe. Another situation is the installation of exhaust gas.

Second: The place where the popping sound comes from:

Vent valve on the mixer: If the motor vehicle itself is equipped with a supercharger, the vent valve will also make a pop sound when the accelerator is added.

If it is a bleed valve on the mixer, it is normal.

If it is a sound near the exhaust pipe, you can consider that the exhaust pipe is not installed properly, and ask the 4S shop to assist in repairing and confirming.

The popping sound found in the exhaust pipe of the car is generally caused by the leakage of the interface pad or hose position of the exhaust pipe.

If the exhaust pipe has a popping sound after the car is repaired, then it must be that there is organic oil in it when it is repaired. It will be fine in two days, don't worry.

1.Over-concentration of mixture: The mixture in the engine is too concentrated and not completely burned and discharged with the exhaust gas, when the unignited mixture enters the exhaust pipe, in.

2.The float chamber oil level is too high: When the float chamber oil level is too high, it will not only cause the combustible mixture to be too concentrated, but also cause part of the fuel to be insufficient.

The exhaust pipe pop is the area of water in the exhaust pipe, and the gasoline is completely burned to produce water and carbon dioxide, and the water is water vapor at high temperatures, and the water vapor is colorless and transparent at high temperatures, but when the temperature is lower than 100 degrees.

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 for the control of engine pollutant emissions of the three-school catalytic converter is also installed in the exhaust system, exhaust pipe one.

The exhaust pipe of the car is normally popping, do you know why? Because there is a three-way catalysis here, it will make this sound when the three-way catalysis is working, which is a normal phenomenon.

The sound of the car exhaust pipe is generally caused by the leakage of the interface pad of the exhaust pipe.

This is normal sound.

Because that's the sound of exhaust gas coming out of the exhaust pipe.

There is also the possibility of exhaust pipes, or there is also the possibility of three-way catalysis.

Normal. Water accumulation in the exhaust pipe does not affect the car. Especially when it is cold, it is common for water to accumulate in the exhaust pipe of the car.

Solution: If there is no air leakage in the exhaust pipe, it is not burning well. It is advisable to check the spark plugs and clean the throttle. Check the ignition coil.

I'm also a car, and I've just driven about 400 kilometers when I notice a popping sound in the right exhaust pipe, like there is water in the exhaust pipe. After opening the 4S shop for the technician to check, the technician hung up the vacancy, hit the throttle on the spot, and the two exhaust pipes immediately blasted out a large amount of water, which is estimated to be quite full of two basins of water, at that time, even the receptionist and technician of the 4S store and several car owners were present to witness the miracle. According to the technician, it is because the weather is too cold and the speed of driving is too slow, which causes something to burn inadequately.

After the new car arrived, it has been driving in the city within 40 yards, and the outdoor weather is indeed low, I don't know if this can really cause the exhaust pipe of a new car to be blocked due to water accumulation. The technician of the 4S shop said that the car during the run-in period can be driven as long as it is under 100 yards, and there is no need to drive at such a low speed. I also asked a friend who works as a mechanic in a car 4S shop to confirm that he also agreed with the Buick 4S shop technician that water accumulation in the exhaust pipe would not have any effect on the car.

Especially when it is cold, it is common for water to accumulate in the exhaust pipe of the car.

Causes of abnormal sound in the exhaust pipe:

1. Step on the accelerator pedal, you will hear the sound of banging from the exhaust pipe, the sound may not be very loud, the car will not be abnormal when driving, fuel consumption will increase, and sometimes similar sounds will come out from the front section. It is advisable to check whether the muffler and exhaust pipe are damaged.

2. When driving at low speed or filling the accelerator, there will be abnormal noise under the engine, especially when the weather is relatively cold. It is recommended to raise the frame and check whether there is a heat shield between the exhaust pipe and the ground, which may be caused by the aging of the heat shield, and it can be solved by replacing or removing it.

3. There is an abnormal sound when turning or moving forward. The common squeak when cornering often comes from the driveshaft of the front wheel with a broken joint, and an intermittent crackling sound is heard. It could be a hole in the exhaust pipe, or maybe some sheet metal or bumper part is coming off.

Automobile exhaust bellows, also known as automobile exhaust hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, so as to play a role in vibration and noise reduction, convenient installation and prolonging the life of the exhaust noise reduction system.

It is mainly used for light vehicles, mini vehicles and buses, its structure is a double-layer bellows covered with steel wire mesh sleeve, the structure of the two ends of the straight edge section jacket snap ring, in order to make the sound reduction effect better, the bellows can be equipped with expansion joints or net sleeves. Material: The main material is stainless steel SUS304, and the ferrule and pipe material can be stainless steel or aluminized steel.

There is a sound like a clattering in the exhaust pipe of the car, there are several possibilities, one is that the partition in the exhaust pipe is broken, the second is that the rubber is off, so that the exhaust pipe and the car body are in contact with the sound, and the third is that the three-way catalytic is broken, and something is dropped into the muffler, you can go to the shelf to check it, you can hear it, and whether the exhaust leak or the exhaust pipe touches the iron frame to make the impact sound. In general, the judgment of the sound is more complicated, the exhaust pipe has a clicking sound, there is a kind of normal, just after running the hot car to stop, the exhaust pipe will sometimes click is the sound of the exhaust pipe contraction, this is a normal phenomenon, if there are other abnormal noises, it is better to go to the maintenance shop to check.

It should be caused by water accumulation in the exhaust pipe.

The so-called pop doesn't necessarily come from the exhaust pipe. Let's start by explaining the exhaust jet sound. The sound of the exhaust pipe depends on two aspects.

One is the material of the exhaust pipe and the sound adjustment of the exhaust pipe. Another situation is the installation of exhaust devices. The popping sound comes from the gas release valve on the mixer.

If the vehicle is equipped with a supercharger, the bleed valve will also make a popping sound when it is installed on the throttle.

Exhaust pipe maintenance.

1. Check the exhaust pipe frequently.

If possible, regularly inspect the exhaust pipe under the vehicle for trauma. Once the exhaust pipe is broken, it should be repaired in time so as not to affect the vehicle.

2. Usually listen to the sound of the exhaust pipe.

If there is an abnormal sound in the exhaust pipe while driving, it may be that the exhaust pipe is swinging and the fixing screw is loose. Go to a repair shop as soon as possible and harden it to prevent it from getting worse.

3. Always check whether there are foreign objects in the exhaust pipe.

Because the exhaust pipe barely leaks to the outside, it is easy to stuff all sorts of things in. Therefore, it is necessary to develop the habit of regularly checking the exhaust pipe mouth, find out the situation in time, and eliminate the danger.
