What is the sound of air leakage from Emgrand GS exhaust pipe?

Reason for air leakage of Emgrand GS exhaust pipe: 1, internal structure of muffler is damaged; 2. The cross-sectional area of the exhaust pipe changes, that is, it is blocked. The muffler cotton in the muffler is aged and deteriorated, which may be blown out by exhaust gas and gradually gather in the exhaust pipe, so that the cross-sectional area of the exhaust pipe changes; 3. The joint between exhaust pipe and muffler leaks; 4, air flow sensor failure, leading to air intake is not allowed, the mixture is too rich.

It should be that water entered the exhaust pipe before and the exhaust pipe leaked, which will lead to this situation.

Need to go to the repair shop to check whether there is air leakage and where it is. In another case, there is something wrong with the ignition system The ignition system of an engine includes an ignition coil and a spark plug. Check the spark plug and ignition coil. If the ignition efficiency of the spark plug decreases, the unburned mixture will explode into the exhaust pipe and burn, and there will be a sudden noise. Without a lot of white smoke, the possibility of flushing the cylinder gasket can be ruled out. Try changing the spark plug first. Water in the exhaust pipe indicates that the combustion is normal. If the engine does not shake, it is normal to have water if the power is enough, and the car burns well.

Reasons for noise in exhaust pipe:

1, the internal structure of muffler is damaged;

2. The cross-sectional area of the exhaust pipe changes, that is, it is blocked. The muffler cotton in the muffler is aged and deteriorated, which may be blown out by exhaust gas and gradually gather in the exhaust pipe, so that the cross-sectional area of the exhaust pipe changes;

3. The joint between exhaust pipe and muffler leaks;

4. This situation is a typical air flow sensor failure, which leads to inaccurate air intake and excessive mixed gas. The fault can be solved by replacing an air flow sensor and cleaning the carbon deposit inside the throttle, nozzle, idle motor and engine.

5. Check the cracks or damaged holes in the exhaust pipe. For small holes, you can stick them firmly with tin foil paper. For larger holes and cracks, you can ask the welding master to help weld the filler. In addition, if the above repairs are not repaired, remember to check whether the muffler inside the exhaust pipe needs to be replaced.

6. If the sound is loud, it means that the exhaust pipe may be shot. Exhaust pipe blasting, that is, fuel burns in the exhaust system, which causes the exhaust pressure to suddenly rise occasionally and make abnormal noise. It may be that the engine is ignited in advance, or the mixture is too thin and the ignition in the cylinder is unsuccessful, or the mixture is too rich and the ignition in the cylinder is unsuccessful.
