Cleaning of automobile three-way catalytic converter
2. When you feel that the vehicle is running out of oil and electricity, you need to check the three-way catalytic converter and clean it as needed;
3. When cleaning the nozzle, throttle and air inlet, it is best to clean the three-way catalyst by the way.
4. It is best to clean the three-way catalytic converter before the annual inspection of the vehicle to ensure that it passes the exhaust gas detection smoothly.
The three-way catalytic converter is honeycomb structure, which is easy to be blocked. Due to the poor quality of fuel in China, the use of manganese-containing antiknock agent in fuel, the use of sulfur-containing and phosphorus-containing antioxidants in lubricating oil and road congestion, the three-way catalytic converter is prone to poisoning failure and blockage.
If this happens, the most effective way is to take it down and clean it, but it is too troublesome and expensive. Therefore, it is necessary to maintain the three-way catalyst at ordinary times.
1. Don't use inferior gasoline.
When the fuel quality is poor, the fuel contains sulfur, phosphorus and lead, and the antiknock agent used contains manganese. These chemical components will form chemical complexes with exhaust gas in the three-way catalyst after combustion. In the long run, Sanyuan will be banned. And this is the main reason of ternary blockage.
2. Try to ensure the normal operation of the engine and make the air-fuel ratio in the best state.
Urban roads are crowded, and the stop-and-go situation will make the fuel burn incompletely, and the products of incomplete combustion will adhere to the surface of the three-way catalyst. It not only increases the working strength of ternary, but also easily forms carbon deposit on ternary, leading to ternary blockage.
Through the comparison in the figure, it can be clearly seen that the three-way catalyst is seriously blocked before cleaning, and the honeycomb results can be clearly seen after cleaning, and the cleaning effect is clear at a glance.
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.
Remove carbon deposit, restore power, solve the problems of high fuel consumption, poor power and substandard exhaust emission, which is simple, fast and worry-free!
