The function of automobile exhaust pipe, what is automobile

When it comes to the exhaust pipe of a car, everyone will have a specific image of it in mind. As for the function of the exhaust pipe on the fuselage of a car, it plays a role of damping and noise reduction, and prolonging the life of exhaust and noise elimination system. The main material of exhaust pipe is stainless steel. For the average car, the exhaust gas leaves the engine under great pressure and the noise it makes can be maddening. The main noise-suppressant is the exhaust pipe.

The function of automobile exhaust pipes -- Brief Introduction

The exhaust pipe is mainly used to reduce vibration and noise (muffling) and reduce harmful gas pollution. In a car, the exhaust gas leaves the engine under great pressure, which makes a lot of noise. The exhaust pipe is equipped with a silencer, which can play a certain role in muffling the noise. There is a "three-way catalytic converter" in the automobile exhaust system, which can reduce pollution. The device can be discharged from the automobile exhaust carbon monoxide, hydrocarbons and nitrogen oxides and other harmful gases into harmless carbon dioxide, water and nitrogen through REDOX, so that the automobile exhaust purification, reduce air pollution.

The role of a car exhaust pipe - What is a car exhaust pipe

Automobile exhaust bellows, also known as the automobile exhaust pipe hose, it is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexible connection, so as to reduce vibration and noise, convenient installation and prolong the life of the exhaust muffler system. It is mainly used for light vehicles, minicar cars and passenger cars, its structure is a double layer bellows covered with steel wire mesh, both ends of the straight side of the outer ring of the structure, in order to make better noise reduction effect, bellows can be equipped with telescopic joint or mesh cover. Material: the main material is stainless steel SUS304, the material of the sleeve and the pipe can be stainless steel or aluminized steel.

The function of automobile exhaust pipe -- how to deal with abnormal sound of automobile exhaust pipe

Abnormal noise of exhaust pipe has the following reasons: 1) Too low idle speed, adjust the idle speed to 750 RPM.

2) If the idle speed is normal, check whether each cylinder of the engine is working and whether there is any rectum problem.

3) The fixing screws of exhaust pipe are loose or the muffler fails. Check whether the fixing screws are tightened all over the exhaust pipe and whether the welds of muffler and exhaust pipe fall off, etc.

When parking the general working normal engine exhaust jet accompanied by sound, in the process of burning work more or less will have the right amount of water vapor generated, and there are a large part of the water vapor condenses into water droplets shape within the rear exhaust muffler by exhaust pipes, and this kind of phenomenon, particularly in the case of low temperature, can be said to be inhaled the mixture formation within the cylinder combustion fully and completely exhaust purification efficiency of a performance.

Therefore, it is a normal phenomenon and there is no need to worry. If there is no abnormality in the engine operation, please feel free to use it safely. In addition, the problem of abnormal noise of exhaust pipe needs to be tested on site.

It is necessary to make an accurate judgment based on the comprehensive analysis of the conditions of abnormal sound production, sound properties and sources. Abnormal sound may occur in the exhaust pipe during driving under the following circumstances.

First of all, the exhaust pipe and the engine are connected by a soft connection, which may be caused by damage of the soft connection after a long time of use. Second, the exhaust pipe is connected to the frame by several rubber rings, which can be checked for damage or rubber aging problems.

Finally, there are seals between the exhaust pipe and the soft connector, between the soft connector and the engine, and you can check if that seal has been damaged. In addition, it is also possible that the owner may accidentally knock out the exhaust pipe when passing through the pothole road without paying attention to it, resulting in the exhaust pipe leakage and abnormal noise, but usually this possibility is very small.

The exhaust pipe of the car is a very important device, but there will be some friends who love to modify the car, most will modify the exhaust pipe, but do not blindly pursue the radius of the exhaust pipe when the modification, although it seems to be very overbearing. But the exhaust pipe radius is too large, will lead to exhaust too unobtrusive, back pressure is insufficient, will cause the car to start weak, fuel consumption will also increase.
