Converting carbon monoxide, hydrocarbons, nitrogen oxides in exhaust into harmless carbon dioxide, nitrogen, water, etc. can meet emission standards such as National V, National VI, Euro V, and Euro VI.

The catalyst coated with wall flow carrier is used to effectively capture particulate matter in gasoline engine exhaust, reduce PM and PN emissions, and convert gaseous pollutants CO, HC, and NOx. Passive regeneration function is achieved through catalyst coating, meeting the national VI and above emission standards for gasoline engines.
