Production Description:

B Three way Catalysts （HS 280530） Three- Way catalysts Close- Coupled catalysts Medium- Coupled catalysts We supply different kinds of catalysts. They can meet different emission standard. Euro II, Euro III, Euro IV, Euro V. All of them have good characteristics: Lower ignition temperature Wider Air- Fuel Ratio window Heat stability Higher tail gas convert ratio Some data are showed in below chart.
