Document Type and Number:
Japanese Patent JP3287853
Kind Code:
B2
Abstract:
There is provided a fine particle-removing device connected to an exhaust path for a combustion exhaust gas, for removing fine particles contained in the exhaust gas. The apparatus comprises filter units (13, 14), a fuel injection nozzle (31) and an ignition device (32). The filter units (13, 14) consist of porous ceramic partitions (21, 22) that form a plurality of narrow paths (23, 24) extending in the direction of a flow of the exhaust gas. The porous ceramic partitions (21, 22) capture the fine particles contained in the exhaust gas when the exhaust gas is introduced into one side and exhausted from the other side of each path (23, 24). The fuel injection nozzle (31) injects a fuel into exhaust gas intake portions of the filter units (13, 14).
