The three-way catalytic converter has stable performance, reliable quality and long service life.
The carrier part of the three-way catalytic converter is a piece of 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 precious metals such as platinum, rhodium, and palladium. It can turn HC and CO in the exhaust gas into water and CO2, and decompose Nox into nitrogen and oxygen at the same time. HC and CO are toxic gases. Excessive inhalation can lead to death, while NOX can directly lead to photochemical smog.
Research has proven that three-way catalytic converters are 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.
All three harmful gases became harmless gases. The three-way catalyst should react at a minimum temperature of 250 degrees Celsius. When the temperature is too low, the conversion efficiency will drop sharply; while the active temperature of the catalyst (the best working temperature) is about 400 °C to 800 °C, and the catalyst will be aged if it is too high. exacerbated. The effect of catalytic conversion is also the best at the ideal air-fuel ratio (14.7:1).
