Where is the automobile three-way catalytic converter?

The automobile three-way catalytic converter is located at the first bump of the exhaust manifold of the automobile chassis, which is a device similar to the shape of a long kettle. Automobile three-way catalytic converter is an important external purification device installed in automobile exhaust system, which converts harmful gases such as CO, HC and NOX emitted by automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The working principle of the three-way catalytic converter is that when the high-temperature automobile exhaust gas passes through the purification device, the purifying agent in the three-way catalytic converter will enhance the activity of three gases, namely CO, HC and NOX, so that they will have certain redox chemical reactions, and the three harmful gases will become harmless gases, thus purifying the automobile exhaust gas.
