FWC™ Catalyst (Four-way Conversion Catalyst)

Application: Emissions control catalyst

Sustainability performance:

  • Euro 6 regulations will enforce, in addition to HC (Hydrocarbons), CO (Carbon Monoxide), and NOx (Nitrogen Oxides), tighter control of PM (Particulate Matter) emissions from gasoline-engine powered vehicles.
  • FWC™ catalyst combines the functionality of a Three-Way Catalyst (TWC) with a filter to remove all four pollutants with just one component.
  • Also lowers backpressure, saves space, ensures particulate emission below tight regulation limits.


Innovative single-component four-way conversion catalyst that removes multiple pollutants from gasoline engine exhaust
