The three-way catalytic converter is a metal device installed in the exhaust system of a vehicle. Its purpose is to reduce the pollutants released into the atmosphere when the internal combustion engine is running. They are made of precious metals, including platinum, palladium and rhodium.Although it was first introduced to the U.S. market in the 1970s due to EPA requirements. However, other countries began to pass laws mandating installation. That's because three-way catalytic converters have done an excellent job of reducing pollution in cities like Los Angeles, which have a serious "smog" problem.


Some little knowledge about BMW three-way catalytic converter:

BMW catalytic converter can be used for up to 10 years without any problems. However, it may be damaged due to contaminants, overheating, blockages or accidents. But how do you know there is a problem?

1. The engine performance is degraded.

If you feel that the engine performance is not as good as before, it may be a problem with the three-way catalytic converter. Since it is directly connected to the exhaust, if it is blocked or ruptured, it will seriously affect the performance of your vehicle.

2. The car makes a "quack" noise.

You probably only hear it when you start your car, but it gets worse over time. The rattle is caused by the collapse of the internal grid due to age and use. So be aware of any clicking noises and check your vehicle's three-way catalytic converter in time.

3. Check whether the engine light is on.

Although the check engine light may then be lit for any reason, but you can use some tools to find out why. You can learn more about using the scanning tool to check the error code, but it is worth noting that there are multiple sensors that can help the three-way catalytic converter to work properly. If you want to ensure that the three-way catalytic converter is in good condition, it is best to diagnose it .
