The Swiss Federal Material Testing and Research Institute (EMPA), in cooperation with
and Umicore, has developed a new catalyst designed specifically for
engines. The companies claim the new catalyst reduces NOx
by around 50 percent and it costs less because it uses fewer precious metals than existing models.
The catalyst has been tested on three vehicles. One of them, a Volkswagen Touran Ecofuel, is going to be shown at at the Zürich Car Show next month (November 1-4th). The Car Show will also feature a range of natural gas vehicles, some of which will be available for visitors to test drive on site.
