works
When the high-temperature automotive exhaust through the purification apparatus, the three-way catalyst scavenger to enhance CO, hydrocarbons and NOx activity of three gases, which causes a certain degree of oxidation – reduction chemical reactions, wherein CO oxidation at high temperatures has become colorless, toxic carbon dioxide gas; hydrocarbon oxidation at high temperatures to water (H20) and carbon dioxide; the NOx reduction to nitrogen and oxygen. Three kinds of harmful gases into harmless gases, to purify the automobile exhaust.
