Filter for cleaning exhaust gases from diesel engine |
摘要 |
A filter for cleaning exhaust gases emitted from a diesel engine is disclosed. The filter is composed of a cleaning portion formed of porous ceramic, through which the exhaust gases flow and in which carbon particulates in the exhaust gases are collected, and an outer wall portion formed of the same kind of material as that of the cleaning portion, which is formed around the cleaning portion so as to be integral therewith. The bulk density of the outer wall portion increases from the inner periphery thereof toward the outer periphery thereof so that the exhaust gases can be prevented from flowing out of the outer wall portion.
