Car exhaust pipe

The so-called “Lu Yao Zhi Ma Li” – the long-term practice in actual use is the best way to test whether a new car is mature in all aspects. The structure of the exhaust pipe is a double-layer corrugated pipe outer cover Wire Mesh cover, and the structure of the snap ring outer cover snap ring at both ends. To make the noise elimination effect better, the bellows can be equipped with a telescopic joint or a net sleeve. The main material of the exhaust pipe is stainless steel, and the sleeve and the connecting pipe material may be stainless steel or aluminized steel.

The exhaust pipe is installed between the exhaust manifold of the engine and the muffler, so that the entire exhaust system is flexibly coupled, thereby providing vibration damping and noise reduction, facilitating installation and prolonging the life of the exhaust muffler system. The exhaust pipe is mainly used for light vehicles, minicars and passenger cars. The structure of the motorcycle and exhaust pipe is a double bellows outer cover steel wire mesh cover, and the straight ends of both ends are covered with a snap ring structure, so that the noise elimination effect is better. Bellows can be equipped with expansion joints or net sleeves. The main material of the exhaust pipe is stainless steel, and the sleeve and the connecting pipe material may be stainless steel or aluminized steel.

Excessive noise in the exhaust pipe may have the following conditions. First of all, there is a soft connection between the exhaust pipe and the engine, which may be caused by damage to the soft connection after prolonged use of the car; secondly, the exhaust pipe and The frame connection is fixed by several rubber rings. It can check whether the rubber ring has been damaged or there is rubber aging problem. Finally, there is a seal between the exhaust pipe and the soft connector, the soft connector and the engine. Check that the seal is damaged.



In addition, it may be that the owner does not pay attention to the use of the process, when the road through the potholes, accidentally damaged the exhaust pipe, causing exhaust pipe leakage and abnormal noise, but usually very unlikely. If a netizen's car also appears to be the case, the Chinese automotive supplies network Xiao Bian suggested that it should be the first time to go to the 4S shop or regular car repair shop for inspection and troubleshooting, do not go to any small repair facilities without qualifications Perform repairs, otherwise there will be no guarantee of after-sales quality.

The reason for the noise is that after the vehicle starts, due to the vibration of the engine, the surface of the metal flange comes into contact with the metal ring of the sealing ring, thereby generating a sound. This will not lead to gas leaks or other functional malfunctions of the vehicle. Usually this sound is not heard when the vehicle is driving, but in a quiet environment, when the customer hears the friction outside the car or when he opens the window, this sound does not cause any functional malfunction. ”

For customers who have repaired once and then experienced abnormal noise of exhaust manifold seals for the second time, do not use replacement parts and wait for market solutions. Maintenance program is being demonstrated, if there is abnormal sound of the exhaust pipe, you can go to the local 4S inspection, confirmed that the exhaust pipe ring. And register. Such maintenance programs come out, whether or not your vehicle exceeds the warranty period, can be resolved free of charge. The noise does not affect the use of the vehicle and has no effect on the durability of the vehicle.



Exhaust pipe - maintenance of the exhaust pipe 1. When the cold car is difficult to start in winter, close the choke valve and start the engine. After the hot car, pay attention to opening the choke valve. It is forbidden to drive at high speed for a long time when the choke valve is closed;

2. Riding vehicles (male vehicles) are prohibited to install windshields or other decorative items in front of the engine and muffler, which will affect the cooling of the engine and muffler;

3. Do not drive for a long time under heavy load and low gear. This will cause damage to the engine and silencer.

4. Do not inflate the throttle at high speed in situ for a long time;

5. When the surface of the muffler is dirty, the color of the surface of the muffler will be discolored, yellowed and blue. In addition, when the muffler surface has a lot of mud and other dirt, please clean up in time to avoid affecting its heat dissipation;

6. When installing the muffler, it should be noted that the muffler pad is installed in place and fastened tightly to prevent air leakage, affecting the muffler effect and causing yellowing at the interface of the muffler;

7. The engine valve clearance, carburetor, air filter, etc. should be adjusted and cleaned in time according to the instructions of the vehicle. If the valve clearance is too small or the mixture is too rich or too thin, it will affect the combustion and affect the muffler. Causes discoloration.
