The cleaning method of the repairman is to blow with high-pressure gas. Blow out the black impurities that have been baked inside the particle trap, as shown in the following figure.
The impurities blown out, as shown in the figure below, are black substances in the shape of columns that can be crushed by hand and are very black.
After more than half an hour of high-pressure gas blowing, the impurities inside the particle trap were basically cleaned up. Then we welded the particle trap and the three-way catalyst together, just like before dismantling, as shown in the following figure.
The state after welding is shown in the following figure.
When the repairman installs the three-way catalyst and particulate trap assembly, starts the engine, the exhaust is smooth, and the power is significantly increased, indicating that the problem has been solved.
