Exhaust manifold for Great wall Haval H9 catalytic converter front with flexible pipe

The working principle of the three-way catalytic converter is: 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 CO, HC and NOx, and promote it to carry out a certain redox-reduction chemical reaction, in which CO is oxidized into colorless and non-toxic carbon dioxide gas at high temperature; HC compounds are oxidized to water (H20) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, so that the exhaust gas of the car can be purified.
