What material is inside the three-way catalytic converter?
1 Answers
The three-way catalytic converter is made of aluminum oxide (Al₂O₃), and the outer shell is generally made of stainless steel. Below is a detailed introduction to the three-way catalytic converter: 1. The interior of the three-way catalytic converter has a mesh structure, which is coated with a purifying agent. 2. The three-way catalytic converter reduces the levels of pollutants in the exhaust gases. 3. The three-way catalytic converter is installed in the exhaust header, located behind the exhaust manifold. 4. There are oxygen sensors both before and after the three-way catalytic converter. The front oxygen sensor primarily measures the oxygen content in the exhaust, allowing the ECU to adjust the air-fuel ratio. The rear oxygen sensor mainly detects whether the three-way catalytic converter has failed.
