ABSTRACT:
The invention relates to a trap for automotive exhaust particulates, with a high trapping efficiency and a low pressure loss for exhaust gas passage. The trap is a honeycomb-type filter with a three-dimensional network skelton. Further, provision of a ceramic incinerator comprising a heater in front of the honeycomb filter makes it easy to incinerate trapped particulates for removal.
