The front section of the car s exhaust pipe, with a mesh in the middle, what happens if it s gone?

It's called three-way catalysis.

It is mainly used to purify exhaust gas. There is a sensor called oxygen sensing gas behind the catalysis, which can monitor the oxygen content of the exhaust gas so that the computer adjusts the amount of fuel injection and ignition advance angle according to it. Without that thing, the exhaust will not be up to standard, it will cost fuel, or the power will drop.

Nadongxi is more expensive and can be sold for money.

It is a three-way catalysis, which is used to turn the harmful substances in the exhaust gas into harmless gases and discharge them into the atmosphere. If not, the annual inspection will not meet the standard. Moreover, the fuel consumption of the engine cannot be controlled in a closed loop, which may cause the fuel consumption to become high.

Summary. Hello, dear, the car master will serve you, attentively, carefully and attentively answer for you, find the corresponding problem solution and solution for you, and will definitely provide you with a satisfactory answer! We hope you find this answer helpful. 

Hello, the exhaust pipe of the vehicle has a mesh thing, this is the soft joint of the exhaust pipe.

First, the main function of this exhaust pipe software is to cushion the vibrations associated with the vehicle's exhaust pipes. Avoid resonance in the exhaust of the vehicle!

Second, this exhaust pipe software is also a sealed body, if there is a problem, then there is no way to replace this alone, only to replace the entire exhaust pipe of this section!

What is the use of having a mesh thing in the exhaust pipe of a car, and what are the functions.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

It is a three-way catalytic process, which converts harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction.

Three-way catalytic principle: when the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, hydrocarbons and NOx, and promote it to carry out a certain oxidation-reduction chemical reaction, in which CO is oxidized at high temperature into colorless and non-toxic carbon dioxide gas; Hydrocarbons are oxidized to water (H20) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, so that the exhaust gas of the car can be purified.

The premise is that oxygen is still available, and the air-fuel ratio is reasonable.

The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system, which can convert harmful gases such as CO, HC and NOx discharged from the automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. Because this catalytic converter can simultaneously convert the main hazardous substances in the exhaust gas into harmless substances. With the increasingly stringent requirements for environmental protection, more and more cars are equipped with exhaust gas catalytic converters and oxygen sensor devices.

It is installed in the engine exhaust pipe, through the redox reaction, carbon dioxide and nitrogen, so it is also called the three-way (effective) catalytic converter The working principle of the three-way catalytic converter is: when the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx, and promote it to carry out a certain redox-reduction chemical reaction, in which CO is oxidized into colorless and non-toxic carbon dioxide gas at high temperature; HC compounds are oxidized to water (H20) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, so that the exhaust gas of the car can be purified.

Three-way catalytic converters for automobiles.

There are harmful gases in automobile exhaust emissions: SO2, CO, NO2 in automobile exhaust, but it is not counted as a harmful gas - because CO2 itself is an important component in the air.

Because the exhaust pipe is a very long pipe that is connected directly to the engine. The vibration of the engine will also be linked to the exhaust pipe, and the vibration of the exhaust pipe can easily cause the vibration of the whole vehicle, and it is easy to produce abnormal noise, which will have an impact on the stability and comfort of the car. Therefore, one to several bellows or mesh pipes are added in the middle of the exhaust pipe design of the car to reduce the transmission of engine vibration to the exhaust pipe, so as to improve the comfort of the car.

It acts as a cushion on the exhaust pipe to reduce the vibration caused by the exhaust pipe.

In order to reduce the vibration of the engine to the rear exhaust cylinder, it plays a cushioning role.

Let's take a brief look at the exhaust system, the initial exhaust gas is a lot of pollution, the first level is to accept the transformation of the three-way catalytic converter.

The three-way catalytic converter converts toxic gases into carbon dioxide and other substances before they can be labeled as qualified, and then the exhaust gas will go to the muffler, and the role of the muffler should also be known, which is to reduce the exhaust noise of the car, and finally it is sprayed out through the tailpipe. Then why is his shape a long strip, our family car, the front of the car to put the engine, in the middle of the seat to hollow out the seat, and the other places are filled with various parts, so the exhaust cylinder is designed to make better use of space, so it is designed into a long strip.

Generally speaking, in countries where the car drives to the right, the driver is on the left, right, in order to ensure the weight balance when a person is driving, the car fuel tank will be designed to the right, and the driver will achieve balance on the left, in order not to compete with the fuel tank, the exhaust pipe will be designed to the left!

The setting of the exhaust pipe is related to road driving, like domestic cars are driven on the right side, and the vehicle is passing from the left side of the pedestrian in the process of traveling, so the exhaust gas emitted by the car at this time will produce a certain amount of exhaust gas to passers-by. If the exhaust pipe is on the right side of the car, a large amount of exhaust gas will cause environmental pollution and cause harm to people's bodies. If the exhaust pipe is on the left, it is still better than these, and the left side belongs to the middle of the road, and the space is relatively circulating.

The exhaust pipe of the car is also very particular.

Because they don't work at the same time, you can switch them.

Let's exhaust the car more smoothly.

It may be that different gases are emitted in different places.

Because such a distribution is suitable for driving.

Yes, there is indeed an in-between.

Because it can be more aesthetically pleasing.

This is because it is more balanced.

It's a unique design, and there's nothing special about it.

Because different models have different locations.

Comparatively speaking, the exhaust pipe of a car is directly proportional to the number of cylinders, and the more cylinders there are, the more exhaust pipes, and the more expensive the vehicle will be.

However, to say that 1 2 4 exhaust pipes represent how many cylinders each represent is not absolute. Why? Some cars have a V6 displacement that doesn't necessarily have dual exhaust pipes.

It could also be one. However, some cars have two exhaust pipes in the V6, like the Audi A4 four-cylinder engine, which has two pipes.

As for the 4 exhaust pipes, they must be exclusive to supercars. It is quite rare in general production vehicles. Probably you've only seen it in magazines or car shows.

Since the power of sports cars and ultra-luxury cars is very high, high power must have large emissions, and it is not surprising that there are several more exhaust pipes, and in order to increase the power of small displacement cars, exhaust pipes will also be added when modifying.

Some cars have a large exhaust volume, and some cars have a small exhaust volume!
