Where is the automotive three-way catalytic converter located?

[VanCatherine]

The three-way catalytic converter is typically installed in the first bulge section of the exhaust manifold under the vehicle chassis, resembling a long kettle-shaped device. Below is relevant information about the three-way catalytic converter: 1. The function of the three-way catalytic converter is to transform harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. This conversion purifies the vehicle's exhaust emissions. 2. The three-way catalytic converter generally consists of four components: the housing, vibration damping layer, substrate, and catalyst coating. 3. The working principle of the three-way catalytic converter is: when the engine exhausts through the exhaust pipe, the three gases (CO, HC, and NOx) pass through the purifying agent in the three-way catalytic converter, which enhances their activity and facilitates oxidation-reduction chemical reactions. Among these, CO is oxidized into colorless, non-toxic carbon dioxide (CO2) gas at high temperatures. HC compounds are oxidized into water (H2O) and CO2 at high temperatures. NOx is reduced into nitrogen (N2) and oxygen (O2).
