Is it useful to clean the three-way catalyst? Is it necessary to use three-way catalytic cleaning in 4s shop?

The three-way catalytic converter is broken, and the automobile exhaust emission must exceed the standard, so the three-way catalytic converter is very important to us. So is it necessary for 4s shop to clean the three-way catalytic converter?

Three-way catalytic cleaning of 4s shop is necessary. Urban roads are crowded, and cars will not burn enough fuel when they start and stop. These products of insufficient combustion will adhere to the surface of the three-way catalyst. If not cleaned, these carbon deposits and particles will pollute the three-way catalytic converter and affect the power or spontaneous combustion of the car, so in order to keep the car unaffected, it is necessary to clean the car.

Automobile three-way catalytic converter is the purification device of the engine, and whether the three-way catalytic converter can work normally determines the working state of the engine in many aspects. Cleaning the three-way catalytic converter is because the content of sulfur and phosphorus in gasoline used in automobiles is relatively high, which will form chemical complexes on the surfaces of the oxygen sensor and the three-way catalytic converter. If the purification is not good, these substances will affect the automobile exhaust and pollute the air.
