Where is the Leiling three-way catalytic converter located?
2 Answers
Leiling three-way catalytic converter is generally located in the first bulge of the exhaust manifold under the car chassis, resembling a long water-drop shaped device. Function of the three-way catalytic converter: It converts harmful gases such as CO, HC, and NOX emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen gas through oxidation and reduction reactions, thereby purifying the automobile exhaust. Composition and principle of the three-way catalytic converter: The three-way catalytic converter consists of four parts: the shell, damping layer, carrier, and catalyst coating. The principle is that 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 the activity of the three gases and carries out oxidation and reduction chemical reactions.
As a veteran driver with over a decade of experience, I believe the location of the Leiling's catalytic converter is on the exhaust pipe, specifically behind the engine exhaust manifold and beneath the chassis, roughly in the area near the front seats. If you crouch down to look under the car, you'll spot a canister-shaped device—that's it. This positioning is designed because the exhaust gases emitted by the engine are at high temperatures and require rapid catalytic treatment of pollutants. Regularly checking for rust or blockages is crucial, as a clogged converter can lead to excessive emissions and increased fuel consumption. Once, I neglected to inspect it, and the converter failed, causing me to fail the annual inspection. It cost me over a thousand yuan to replace it later. When driving, be careful not to scrape the undercarriage, as impacts can damage the converter. It's best to have a mechanic inspect it every couple of years to ensure it's functioning properly.
