Repair method of motor vehicle exhaust purifier

Abstract

The invention discloses a repairing method for a motor vehicle exhaust purifier. The method includes the following steps that a, the purifier is cleaned; b, the cleaned purifier is dried with hot air; c, the dried purifier is coated with a repairing agent through a vacuum device; and d, the coated purifier is dried and activated with hot air. Compared with the prior art, the repairing method for the motor vehicle exhaust purifier has the following advantages that the repaired purifier can ensure that exhaust emission meets the national IV and V standards; the repairing process is simple in operation, rapid and effective; waste water, waste gas and solid waste are not generated in the repairing process, the environment is not polluted, and the repairing process is environmentally friendly; the reproduced purifier can further improve the work efficiency of a whole exhaust system, power is increased, and oil consumption is reduced.

Description

technical field [0001] The invention relates to a method for repairing a motor vehicle tail gas purifier, belonging to the field of motor vehicle tail gas purification treatment. Background technique [0002] At present, motor vehicle (gasoline vehicle, light-duty diesel vehicle and heavy-duty diesel vehicle) exhaust purifier is the most effective way to treat and reduce exhaust gas and carbon particle emissions. However, due to the different fuel quality in different places and the different engine working conditions caused by the car owners' habits, the purification effect of the purifier will decline to varying degrees after the purifier is used for a period of time, which seriously leads to its purification effect. It can't meet the national standard, can't pass the exhaust gas detection, and at the same time, it can block the purifier, affect the power of the motor vehicle, cause the lack of power of the motor vehicle, and increase the fuel consumption of the motor vehi...

AI Technical Summary

Problems solved by technology

At present, the cleaning method is mainly used in China, but the existing method of cleaning the purifier does not play a good role in maintaining the purifier. In many cases, the exhaust emission after cleaning is still not up to the standard, or even worse.

This is mainly because a part of the functional coating will be lost during the cleaning process. Due to the loss of the effective functional coating of the purifier after cleaning, the purification effect of the purifier will be greatly reduced. In serious cases, it cannot meet the national emission standards and cannot pass the exhaust gas detection.
