Particle filter for exhaust line of diesel engine of motor vehicle, has gas outlet end associated to magnetic field generation units attracting residues in gas and sensitive to field, where filter has honey-comb structure with porous walls

摘要

The filter (31) has a gas inlet end (32), and a gas outlet end (33) associated to magnetic field generation units (34) that attract residues contained in the gas and those sensitive to a magnetic field. The generation units have an electromagnet whose electrical energy supply is controlled by control units. The filter has a honey-comb structure with a succession of porous walls that are made of porous material.
