Description

technical field [0001] The invention discloses an environmental-friendly comprehensive cleaning device for a National VI post-processor, belonging to the field of vehicle post-processor cleaning devices. Background technique [0002] The post-processor is the most important off-board purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. [0003] Whether the post-processor can work normally determines the working status of the engine such as fuel consumption, power, and emissions. If the afterprocessor is clogged or malfunctions, then the first thing to do is that the vehicle exhaust emissions exceed the standard. In addition, it will also affect the performance of the vehicle engine, often manifested as increased fuel consumption, weak acceleration, abnormal noise from the exhaust pipe, and unpleasant...

Problems solved by technology

However, on the one hand, the operation of this cleaning method is relatively rough, and the waste water from cleaning is serious. In the process of purging, there is a situation of destroying the mesh

[0006] In addition, the inner wall of the post-processor grid is easy to accumulate liquid, and it is easy to crack the inner wall of the grid after freezing in winter in the north, resulting in damage to the post-processor
