Frequently asked questions about exhaust flexible pipe

Common problems of exhaust flexible pipe generally appear in two aspects. Including drainage and smoke exhaust, then from these two aspects, let's introduce the failures and solutions of exhaust flexible pipe.

Here is the content list:

The drainage problem of exhaust flexible pipe

Dripping water from the exhaust flexible pipe of the car is a good phenomenon. It proves that your car's engine is fully burned, and the exhaust flexible pipe of the car will drip outwards. This is a normal phenomenon, and it has nothing to do with the exhaust flexible pipe.

The reason why the exhaust flexible pipe drips are that carbon dioxide and water are generated after the car gasoline is completely burned. At high temperatures, the water turns into water vapor, and water vapor is colorless and transparent at high temperatures. However, when the water is lower than 100°, the water vapor is It will condense into water. If the condensed water droplets of the exhaust flexible pipe are small and suspended in the air, the water vapor will appear as white gas, but when the temperature is low, the exhaust flexible pipe will emit white smoke as water vapor; if the exhaust flexible pipe is condensed The droplets of water accumulate and become water. The water droplets discharged from the exhaust flexible pipe are the water vapor generated after the gasoline is burned. It is the result of condensation in the exhaust flexible pipe and the muffler. When the ambient temperature is high, the water vapor of the exhaust flexible pipe is discharged before it has been condensed. When the ambient temperature of the exhaust flexible pipe is low, water vapor will condense into water droplets on the wall of the exhaust flexible pipe and flow out with the exhaust.

If there are too many, it may be that the exhaust flexible pipe has accumulated water at this time. It is recommended that you go to the store where you bought it to change one if there is a warranty, it is free.

Exhaust smoke problem of exhaust flexible pipe

After the automobile diesel engine is started, the exhaust flexible pipe emits a large amount of off-white smoke

Failure analysis:

This kind of failure is generally caused by the diesel fuel injected into the cylinder by the exhaust flexible pipe being discharged without burning or entering the cooling water in the combustion chamber.

cause of the issue:

1exhaust flexible pipe. The injectors of individual cylinders have poor atomization.

2 The injection pressure is low.

3 The fuel injector has serious dripping.

4 The ambient temperature of the exhaust flexible pipe is too low, which leads to no combustion or poor combustion in individual cylinders.

5 There is water in diesel oil.

6 Water droplets penetrated individual cylinders.

7 Exhaust flexible pipe fuel supply advance angle is incorrect.
