What is the performance of the car’s three-way catalytic converter broken? How many years do the three-way catalytic converter be replaced?

Car threeYuanCatalytic converter failures are usually accompanied by engine failure lights, increased vehicle fuel consumption, reduced power, poor exhaust, engine carbon deposits, and increased exhaust pollution. Under normal circumstances, the three-way catalytic converter will not break easily. Basically, it is not a problem to replace it with a 200,000 kilometers. However, due to the fuel quality of the vehicle and the environment and other factors, the three-way catalytic converter will have a certain life span. The degree of shortening.

The specific manifestations of the failure of the three-way catalytic converter:

1. The engine fault light is on

When the engine electronic control ECU fails to detect or the oxygen sensor signal is abnormal, the engine fault light will light up.

2. Increase in fuel consumption and decrease in power

It affects the signal of the oxygen sensor to be normal, which results in the engine's inability to accurately control the fuel injection volume, which in turn will cause the phenomenon of increased fuel consumption and decreased power.

3. Poor exhaust

The three-way catalytic converter is clogged, and at the same time it is easy to cause the engine temperature to be too high

4. Engine carbon deposits

As the air-fuel ratio of the combustible mixture in the cylinder is seriously unbalanced, the carbon deposits produced by incomplete combustion will accumulate in the cylinder in a large amount, thereby increasing the formation of carbon deposits.

5. Exhaust gas pollution has increased

The failure of the three-way catalytic converter reduces the catalytic reduction of harmful gases emitted by the exhaust, and the exhaust pollution of the vehicle will be aggravated.

In order to avoid failure of the three-way catalytic converter, car owners can clean the three-way catalytic converter regularly, usually every 30,000 kilometers. The price of cleaning the three-way catalytic converter project on the market is around 200-800 yuan.
