摘要

The IC engine exhaust system comprises a grid of resistance wire mounted at the upstream end of a particle filter (34). The grid and/or filter are coated with catalyst. A control unit (44) regulates the temperature of the grid to produce the desired quality of purified exhaust : An independent claim is included for a method for regenerating the particle filter using the system.
