Through advanced filtration technology and high - quality materials, we ensure that our DPFs meet the most stringent environmental standards helping to improve air quality and protect the environment.
Although in most cases, the three-way catalyst can be solved by cleaning, if it is broken, it can only be replaced.
I. How to calculate the damage
When the three-way catalyst is working, its damage forms are usually manifested as: catalyst losing activity or shell damage.
Loss of activity is commonly known as "three-way catalytic converter poisoning", mainly due to the reaction of sulfur, lead, phosphorus, zinc and other chemicals in gasoline and engine oil with the catalyst, resulting in the so-called "degradation" of the catalyst.
The damage of the shell is when you drive, it is constantly bouncing there, or the chassis is scraped, or the body vibrates. All of these may lead to the fragmentation of the catalyst carrier, that is, the external ceramic body, and the catalytic function will also fail.
II. Decide whether to replace the three-way valve
Generally, we are not aware of the damage to ourselves, so it is only possible to discover it when the annual inspection reveals that the exhaust gas does not meet the standards, and then we will consider replacing the three-way catalyst.
When the annual inspection fails, we drive the car to the repair shop for testing. If the removed three-way catalyst vibrates and makes a sound like "bang bang", it is likely that the ceramic body has broken and needs to be replaced.
