Can automobile three-way catalysis be blown with air gun?

Three-way catalytic converter is the most important external purification device installed in automobile exhaust system. It can convert harmful gases such as carbon monoxide, hydrocarbons and nitrogen oxides in automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. When the high-temperature automobile exhaust gas passes through the purification device, the purifying agent in the three-way catalyst will enhance the activities of CO, HC and nitrogen oxides, and promote them to carry out certain redox chemical reactions, in which CO is oxidized into colorless and nontoxic carbon dioxide gas at high temperature; HC compounds are oxidized to water (H2O) and carbon dioxide at high temperature; Nitrogen oxides are reduced to nitrogen and oxygen. Three kinds of harmful gases are changed into harmless gases, thus purifying automobile exhaust.

Maintenance of three-way catalytic converter: 1. Don't use inferior gasoline. When gasoline contains a lot of lead or other impurities, some impurities will remain after combustion, and some of them will be discharged into the three-way catalytic converter along the exhaust pipe. In the long run, the three-way catalytic converter will be blocked. And this is also the main reason of ternary blockage.

2, try to ensure the normal operation of the engine, make the air-fuel ratio in the best state. If the fuel is not fully burned, it will inevitably form carbon deposit, which not only increases the working intensity of ternary, but also easily forms carbon deposit on ternary, leading to its blockage. 3. After cleaning the throttle and nozzle, it is recommended to clean Sanyuan again. This is because the carbon removed when cleaning the throttle and fuel nozzle enters the three-way catalytic converter with the exhaust pipe. When carbon deposition is serious, it will block the ternary.
