Description

Technical Field

[0001] This invention relates to the technical field of exhaust gas treatment, and more particularly to an exhaust gas aftertreatment device capable of self-cleaning impurities. Background Technology

[0002] The exhaust pipe is installed between the engine's exhaust manifold and the muffler. Traditional exhaust pipes generally have a simple structure, resulting in poor cleaning of exhaust gases, which can easily lead to environmental pollution and the accumulation of impurities inside, affecting their lifespan. Furthermore, cleaning the inside of the exhaust pipe typically involves manually attaching a cleaning cloth or brush to a small cylindrical tool and inserting it into the exhaust pipe. This method can easily cause unnecessary damage to the exhaust pipe when inserting the tool, and it cannot completely remove debris, leading to a large amount of residue inside the exhaust pipe that can affect subsequent use. Therefore, an exhaust pipe must not only purify exhaust gases and prevent environmental pollution, but also have a self-cleaning function.

[0003] In summary, to achieve exhaust gas purification and self-cleaning capabilities in exhaust pipes, a simple and efficient exhaust gas aftertreatment device is needed. Therefore, we propose an exhaust gas aftertreatment device capable of self-cleaning impurities to address the aforementioned problems. Summary of the Invention
