| 摘要 |
The invention generally concerns the field of particle filters and more particularly, an exhaust gas filtering device for a diesel engine. The invention aims at providing a novel manufacturing and assembling technique for a filtering medium, which enables substantial reduction of thermal and mechanical stresses upon sudden combustion of deposited carbon particles (with no inconvenience), so as to eliminate cracks resulting therefrom. Therefor, the invention provides an exhaust gas filtering device comprising at least an assembly of filtering units separated from one another, each being fixed by being bonded on a support via a bonding seal, so as to provide it with thermal insulation and mechanical independence relative to the neighbouring units. |
