Abstract
An exhaust gas-treating process by capturing particulates in exhaust gas discharged from an internal combustion engine with use of a honeycomb structural filter, the process including the steps of: (1) capturing the particulates contained in the exhaust gas by passing the exhaust gas through the filter; (2) stopping flow of the exhaust gas through the filter and transferring the captured particulates to a location remote from and outside an exhaust line by flowing the particulates captured by the filter in a direction reverse to a flowing direction of the exhaust gas; and (3) burning the particulates and discharging a burnt matter outside. The filter preferably has a honeycomb structural body and second sealed portions in first and second rows at opposite ends of the honeycomb structural body, respectively. Gas stream-introducing channels are each provided near and upstream of said first sealed portions in a respective one of said first rows and penetrating inner walls in the respective one of said first rows, while each of the gas stream-introducing channels penetrates an outer peripheral wall of the honeycomb structural body at at least one of opposite ends thereof.
