Exhaust gas is not up to standard is a common problem in the automotive field, which may cause the engine fault light to light up.Among them, the three-way catalyst problem is a common cause of the fault light.If we encounter this situation, we need to take some measures to solve the problem.First of all, we should check whether the surface of the three-way catalyst is too dirty. If it is, it can be cleaned to achieve the best conversion effect.It is suggested to clean the engine carbon deposits every twenty or thirty thousand kilometers, so as to prolong the service life of the engine and make it work optimally.Through cleaning, we can remove the carbon deposits inside the engine, make the exhaust emission more up to standard, and improve the performance of the engine.In addition, we should also pay attention to regularly replace the air filter and oil filter, so as to ensure the normal operation of the engine.In a word, as long as we adopt the correct maintenance method, we can effectively solve the problem of exhaust gas not up to standard.

If the three-way catalyst problem is found, it needs to be cleaned in time.There are many cleaning methods. You can choose professional cleaning agent or use high pressure water gun to clean. But it is necessary to avoid damaging the catalyst surface when cleaning. In addition, if the three catalytic converter has been damaged, it needs to be replaced in time, otherwise it will have a negative impact on the vehicle's emissions. When replacing the catalyst, the quality of the product should be guaranteed to ensure its performance and service life. At the same time, the condition of the catalyst should be checked regularly to avoid problems. In a word, for the three catalytic converter problem, it is very important to take timely measures.
