The main function of bai is to reduce engine noise and pollutants emitted.
The structure of the exhaust system of a car is very complicated, not just a tube. The core components are the three-way catalytic converter and muffler. The three-way catalytic converter can convert harmful gases such as CO, HC and NOx from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. When the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, and promote certain oxidation-reduction chemical reactions. Among them, CO becomes non-oxidized at high temperature. Color, non-toxic carbon dioxide gas; HC compounds are oxidized to water (H20) and carbon dioxide at high temperature; NOx is reduced to nitrogen and oxygen. Three kinds of harmful gases become harmless gases, so that automobile exhaust can be purified.
