Particle filter bag for use in internal combustion engine, has filter surfaces, which limits hollow space of bag and enlarge around additional filter surfaces at inflow and outflow sides, where spacer is accomodated in hollow space

摘要

A bag (40) has filter surfaces (30, 32), which limit a hollow space (34) of the bag, where a spacer (46) is accommodated in the hollow space. An inflow side (12) and an outflow side (14) are provided in the bag. The filter surfaces enlarge around additional filter surfaces (52) at inflow and outflow sides. The filter surfaces are manufactured from a sinter material and include a carrier material with openings for receiving the sinterable material.
