The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system, which can transform the harmful gases such as CO, HC and NOx discharged from the automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. When the high-temperature automobile exhaust passes through the purification device, the purifying agent in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, and promote it to undergo a certain oxidation-reduction chemical reaction, in which CO oxidizes to become colorless and non-toxic carbon dioxide gas at high temperature; HC compounds oxidize to water (H2O) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. Three harmful gases become harmless gases, so that car exhaust can be purified.

Installation Instructions

The three-way catalytic converter has stable performance, reliable quality and long life, and its products are widely used in Toyota, Honda, Buick, Audi, Volkswagen, Hyundai, Suzuki, Changhe, Mercedes-Benz, BMW, Porsche, Land Rover, Fiat, Alfa, Bentley and other models. The carrier part of the three-way catalytic converter is a porous ceramic material, which is installed in a special exhaust pipe. It is called a carrier because it does not participate in the catalytic reaction itself, but is covered with a layer of platinum, rhodium, palladium and other precious metals. It can turn HC and CO in the exhaust gas into water and CO2, while decomposing NOx into nitrogen and oxygen. HC and CO are toxic gases, and excessive inhalation will lead to death, while NOx will directly lead to the occurrence of photochemical smog. Studies have shown that the three-way catalytic converter is the most effective way to reduce these emissions. Through oxidation and reduction reactions, carbon monoxide is oxidized to carbon dioxide, hydrocarbons are oxidized to water and carbon dioxide, and nitrogen oxides are reduced to nitrogen and oxygen.
