What will happen to the three-way catalytic blockage on the car?

After the three-way catalytic converter in the car is blocked, the consequences are still very serious, which may lead to excessive exhaust, poor exhaust, reduced power, engine jitter, or flameout, and even serious spontaneous combustion symptoms.

If the symptoms are mild after the blockage, but it has not been detected by professional instruments, we can't find anything abnormal. During the blockage period, chemical compounds may be adsorbed on the surface of catalytic converter, which mainly shows that the purification function of automobile exhaust is relatively low, the exhaust emission is seriously exceeded, and even colored smoke can be seen in the exhaust pipe.

If the blockage is moderate, general chemical compounds may accumulate on the surface of the catalyst to some extent, but during this period, the exhaust pipe will increase the pressure and fuel consumption appropriately, and the driving force will decrease. And at this stage, the engine fault light will automatically light up.
