摘要

Reducing the particle content of IC engine exhaust (6) comprises separating and agglomerating the particles and then converting them. The first two stages are carried out using a first electric field (5) and the third stage using a second field (9). An independent claim is included for an apparatus for carrying out the above process with electrodes (3, 4, 10, 11) which produce the fields.
