How long does it take for the tail gas to emit white smoke after cleaning up the carbon deposit?

The time to solve the problem of white smoke from tail gas after carbon deposition removal depends on the specific vehicle condition and cleaning method. The cause of white smoke in tail gas may be related to many factors, such as insufficient combustion caused by carbon deposit blockage or high water content of combustion substances. Cleaning up carbon deposits is to solve these problems and reduce white smoke. Here are some possible time frames:

1. Simple cleaning method of carbon deposit: It usually takes one to several hours to clean with chemicals or additives. But after using this method, it may take some time to see the effect.

2. Mechanical cleaning methods: for example, removing and cleaning the throttle valve, cleaning the fuel nozzle or combustion chamber, which takes a long time, usually several hours to one day.

Please note that if your vehicle already has other problems, such as engine sensor or fuel nozzle failure, even if you clean up the carbon deposit, you may not be able to solve the problem of white smoke in the exhaust immediately. At this point, you may need to further check and repair other possible faults.

In addition, the severity of white smoke in the exhaust gas also depends on the use and driving conditions of the vehicle. If you often drive in the city or in traffic jams, you may be more likely to produce white smoke. Therefore, cleaning up carbon deposits in time and adopting reasonable driving habits will help reduce the problem of white smoke in exhaust gas.
