Automobile exhaust muffler catalytic converter BMW F18 MINI X5

When the engine exhausts through the exhaust pipe, the three toxic gases CO, HC, and NOx pass through the purifier in the catalytic reactor, which enhances the activity of the three gases and undergoes chemical reactions such as oxidation and reduction. Among them, CO will be oxidized at high temperatures. , turns into colorless and non-toxic CO2 gas, HC is oxidized into water and carbon dioxide at high temperature, while NOx is reduced into ammonia. The three harmful gases finally turn into harmless gases, and the prerequisite for changing from harmful to harmless is a good quality three-way catalytic converter.
