1, the car equipped with a Direct- Fit Three Way Catalytic can not use leaded gasoline, because after the combustion of lead-containing oil, lead particles with the exhaust gas discharged through the Three way catalytic converter, will cover the surface of the catalyst, the catalyst area is reduced, thus greatly reducing the conversion efficiency of the catalytic converter, resulting in lead poisoning of the exhaust pipe catalytic converter. 2, should avoid the unburned mixture into the catalytic converter. The temperature at which the three-way catalyst begins to work is about 200 degrees Celsius, the best working temperature is 400 degrees Celsius to 800 degrees Celsius, and the precious metal composition of the catalyst itself will also produce chemical changes after more than 1000 degrees Celsius, so that the effective catalyst composition in the catalyst is reduced, so that the catalytic effect is weakened. Therefore, the following situations should be excluded during the use of t…
