The life of the three-way catalytic converter, does the failure of the three-way catalytic converter affect the car?

Catalysis is an important part of gasoline vehicle exhaust purification. The carrier component is a piece of porous ceramic material, installed in a special exhaust pipe, and the surface of this piece of porous ceramic material is covered with a layer of platinum, rhodium, palladium and other precious metals and rare earth coatings, which is responsible for carbon monoxide ( CO), hydrocarbons (HC) and nitrogen oxides NOx and other harmful gas redox important substances (the carrier part does not participate in the reaction).

Three-way catalytic converter life

The life of the three-way catalytic converter is related to the fuel quality and use environment of the vehicle, and there is no specific service life standard. But under normal circumstances, excluding the interference of external bad phenomena, three-way catalysis can basically be used for 200,000 kilometers without a problem.

The impact of three-way catalytic failure on the car

1. Exhaust gas pollution increases

Without the three-way catalysis to catalytically reduce the harmful gases emitted by the exhaust, the exhaust pollution of the vehicle will be aggravated.

2. Engine fault light is on

When the electronic control ECU of the engine cannot detect or the signal of the oxygen sensor is abnormal, the engine fault light will light up.

3. Increase in fuel consumption and decrease in power

The three-way catalytic damage will affect the normal signal of the oxygen sensor, which will result in the engine's inability to accurately control the fuel injection volume, which will result in an increase in fuel consumption and a decrease in power.

4. Carbon accumulation

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 "chronic disease" of the engine.
