• Eminox has collaborated with catalytic convertor manufacturer Johnson Matthey to develop a combined catalyst and filter trap for heavy diesel engines.
In tests the Continuously Regenerating Trap (CRT) has reduced gaseous pollutants by up to 100% and soot emissions by more than 80%.
The device consists of a Johnson Matthey catalyst and "wall-flow" filter housed in an Eminox "Greencat" modular stainless-steel exhaust.
The "wall-flow" filter does not need to be replaced because the soot is continuously oxidised; it forms carbon dioxide and water vapour using the gases from the catalyst. Regeneration does not need additional heaters or controls.
Eminox claims that the system also eliminates smoke and diesel smell.
Cambridge bus operator Cambus has taken the first two CRT systems: it has installed them on 25-seater Metroriders fitted with Cummins B-Series Euro-1 engines for use in pedestri anised streets in Cambridge.
According to Eminox, the CRT is suitable for all heavy truck applications.
