Technologies -> 4-way Diesel Systems -> NAC + DPF

A NOx adsorber catalyst and a diesel particulate filter may be used together to give effective removal of CO, HC, PM and NOx from a diesel exhaust.

Different system configurations using the two technologies have been developed by Johnson Matthey to achieve a suitable balance between performance, durability and size.

Typical applications:
Truck and Bus
Non-road Mobile Machinery
Cars, Vans and Light Trucks
