Particle filter for exhaust system has filter substrate in form of hollow body with cavity in flow connection with inlet

摘要

A particle filter (10) has a housing (14), an inlet (12), an outlet (16) and a filter substrate (18) in the flow path between the inlet and the outlet. The filter substrate is in the form of a hollow body with its cavity in flow connection with inlet, so that the flow path from the inlet passes through the filter substrate and then goes to the outlet.
