The object of the invention is a porous sheet(s) for treating exhaust gases of combustion engines in open channels. According to the invention at least part of the porous sheet has a covering support having pores over 10 nm and coarse particles over 1.4 &#x3bc;m.

Substrate having porous sheet(s) for treating exhaust gases of combustion engines

A substrate has corrugated sheet(s) and channel(s) for treating exhaust gases of combustion engines. The present invention also relates to methods for manufacturing and using the substrate having the open channel(s). The substrate () includes at least one corrugated sheet () having depressions () and one flat wire mesh sheet () having depressions () which is connected to the corrugated sheet () and between the flat wire mesh sheet () and the corrugated sheet () there are at least partially open channels (POC) for exhaust gas (EG) flow, and the depth of depression () of the flat wire mesh sheet () is 0.05-2.0 mm smaller than the height of the corrugation () of the corrugated sheet ().
