Pollution reducing particle filter for automobile engine exhaust line, comprises porous, honeycomb structure block of catalytic material which reduces nitrogen oxides in exhaust gas

摘要

In a particle filter for the exhaust line of a internal combustion engine in an automobile, of the type comprising a porous block (32) of honeycomb structure with inlet channels (34) and outlet channels (36), the porous block is of catalytic material (A) suitable for reducing nitrogen oxides in the exhaust gas. Independent claims are included for: (1) an antipollution system for the exhaust line of a internal combustion engine in an automobile, consisting of a particle filter as above and a plasma reactor for generating non-thermal plasma, with the electrodes located in the channels (36) of the particle filter; and (2) an exhaust line incorporating the particle filter or the antipollution system.
