Do Vans Have Catalytic Converters?
1 Answers
Generally, they are equipped with catalytic converters as mandated by national regulations to prevent direct air pollution from exhaust emissions. Here is some relevant information about catalytic converters: 1. A catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. When high-temperature vehicle exhaust passes through the purification device, the catalyst in the catalytic converter enhances the activity of CO, HC, and NOx gases, promoting specific oxidation-reduction chemical reactions. 3. The catalytic converter is the most critical external purification device installed in a vehicle's exhaust system. 4. Since this converter can simultaneously transform the three major harmful substances in exhaust gases into harmless substances, it is referred to as a three-way catalytic converter.
