Ceramic monolith for exhaust gas particle filter of e.g. oil engine, has channel forming gas outlet channel, and another channel comprising upstream cap at its upstream end and another cap for forming closed chamber

摘要

The monolith (6) has a gas inlet channel (10), and channels (12, 14) adjacent to the channel (10), where the channels cross the monolith between a gas inlet surface and a gas outlet surface. The channel (10) comprises a downstream cap (22) at its downstream end, and the channel (12) forms a gas outlet channel. The channel (14) comprises an upstream cap (24) at its upstream end, and a cap (26) for forming a closed chamber (28).
