Product Description

Reaction principle:
   Oxidation: HC + O2 → CO2 + H2O
         CO+O2 → CO2
   Reduction: NO+CO → N2+CO2
         NO+HC → CO2+N2+H2O
         NO+H2 → N2+H2O
Water vapor reformation: CO+H2O → CO2+H2
          HC+H2O → CO+H2
Emission standards: National IV, National V, National VI

Exhaust emission characteristics: conventional pollutants CO, HC, NOx, complex composition, high temperature, high air velocity, therefore very demanding requirements on the catalyst. In order to obtain the best conversion efficiency, the engine must work within a very narrow air-fuel ratio range (close to the theoretical proportioning state).

Features of our gasoline engine catalysts:
●Excellent catalyst performance, wide triple effect window, high conversion efficiency
●Excellent temperature, air speed and air-fuel ratio characteristics
●Higher cost performance due to low content of precious metals in catalysts with targeted materials and processes
●Uniform catalyst coating, firm and non-depleting
●Excellent durability performance
Application areas: Gasoline vehicles
