Common problems of three-way catalytic converter;
How to construct 1 and three-way catalytic converter?
Three-way catalytic converter is an environmentally friendly exhaust gas purification device, which is installed on the automobile exhaust system. Its shell is metal, and its interior is a honeycomb ceramic carrier with about 80 meshes per square centimeter. The carrier is coated with noble metal catalyst (such as platinum, rhodium, palladium, etc.). ).
2. What is the working principle of three-way catalytic converter?
When the engine is working, the generated high-temperature gas passes through the three-way catalytic converter. When the temperature of the catalytic converter reaches 400℃, the precious metals in the device play a catalytic role, and the exhaust gas is combusted for the second time, so that carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NO) in it undergo redox reactions and are converted into carbon dioxide (CO2), nitrogen (2) and water (H2O).
3. What are the common fault types of three-way catalytic converter?
A, driving more than10-200,000 kilometers exceeds the service life; B, high temperature sintering deformation, effective coating damage or disappear; C, chemical poisoning failure; Rust scale and carbon scale are blocked.
4. How long is the warranty period of the three-way catalytic converter? Do you support 7-day unreasonable return?
After purchase, as long as the quality of the three-way catalytic converter is determined to be faulty, there is no reason to return it within 7 days. The three-way catalytic converter is guaranteed for one year. If it can't be installed (provide comparison photos) and the exhaust gas is tested once a year, but (provide complete photos of the test report and indicate the date), the alarm code of the fault light is P0420 or P0430 (provide photos of the test results of the fault light code), and it can be replaced free of charge during the warranty period. All products on this website do not bear any expenses other than accessories (including installation fees).
