Abstract
An ash filter for a reciprocating piston internal combustion engine is disclosed. The ash filter includes a substrate, such as a honeycomb monolith substrate or a plurality of particulate substrates, and a matrix of a zeolite material disposed on the respective substrate or substrates, the matrix of the zeolite material configured to remove ash from an exhaust gas flow from a reciprocating piston internal combustion engine. An exhaust treatment system for a reciprocating piston internal combustion engine is disclosed. The exhaust treatment system includes an ash filter comprising a matrix of a first zeolite and configured to receive an exhaust gas flow from an engine; and an exhaust treatment device, the exhaust treatment device comprising a matrix of a second zeolite and configured to receive the exhaust gas flow from the ash filter.
