Do Aftermarket Three-Way Catalytic Converters Contain Metal?
1 Answers
Generally, qualified aftermarket three-way catalytic converters contain metal content. These include precious metals such as platinum (Pt), rhodium (Rh), and palladium (Pd). Below is some additional information: 1. Three-Way Catalytic Converter: A three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases like CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Precautions: High-quality aftermarket three-way catalytic converters are generally fine, but the automotive parts market is mixed with varying quality. It is recommended to replace the catalytic converter with an original equipment manufacturer (OEM) part at a 4S shop. Typically, OEM catalytic converters offer better compatibility than aftermarket ones. Using a low-quality catalytic converter can not only lead to excessive emissions but also increase exhaust backpressure, negatively affecting engine performance.
