Do China III Vehicles Have Three-Way Catalytic Converters?
1 Answers
Most China III vehicles are equipped with three-way catalytic converters. Below is an introduction to automotive three-way catalytic converters: 1. Working Principle: When high-temperature exhaust gases pass through the purification device, the catalyst in the three-way catalytic converter enhances the activity of CO, hydrocarbons, and NOx, promoting specific oxidation-reduction chemical reactions. CO oxidizes into colorless, non-toxic carbon dioxide gas at high temperatures; hydrocarbons oxidize into water (H2O) and carbon dioxide; and NOx is reduced into nitrogen and oxygen. 2. Function: It converts harmful substances in the exhaust, such as hydrocarbons, carbon monoxide, and nitrogen oxides, into harmless substances like water, carbon dioxide, and nitrogen, thereby reducing engine emission pollution.
