Vehicles emit pollutants into the atmosphere mainly through exhaust emissions, fuel evaporation, and crankcase blow-by. Among them, exhaust emissions have the greatest impact on the atmosphere. The pollutants emitted are mainly carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOX). Research has proved that three-way catalysts are the most effective in reducing exhaust pollutant emissions. Methods. Automobile exhaust three-way catalytic converter is the most important external purification device installed in automobile exhaust system. It can convert harmful substances in automobile exhaust into harmless carbon dioxide, waterandnitrogen.When the high-temperature automobile exhaust gas passes through the purification device, the purifying agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx, and promote them to carry out a certain oxidation-reduction chemical reaction, in which CO is oxidized at high temperature to become non-volatile 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 car exhaust can be purified， Because this catalyst can simultaneously turn the three main harmful substances in the exhaust into harmless substances, it is called a three-way catalyst.
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...
The catalyst center carrier is a honeycomb porous thin-walled ceramic material, which has the advantages of small airflow resistance, large geometric surface and no wear. It is installed in a special exhaust pipe, and the surface of the carrier is covered with a layer of precious metals such as platinum, rhodium, palladium, etc. catalysis.
The three-way catalytic converter is generally composed of a carrier, a coating, a catalyst, a gasket, a shell, a heat shield and a connecting flange. Its purification efficiency is very high and can purify more than 90% of harmful substances. This component plays an important role in emission treatment. Important position. Our sales, engineering, and manufacturing teams have the experience and expertise in a range of industries, ensuring your 3 way catalytic converter will meet or exceed your expectations.
