Siloxane filtration system and method
A particulate and siloxane filtration system may include a housing and a filter media assembly. The filter media assembly may be disposed within the housing and positioned to filter intake gases to an internal combustion engine. The filter media assembly may include a particulate media configured to remove particulates from the intake gases and a siloxane media configured to remove siloxanes from the intake gases.
1. A method of filtering particulates and siloxanes from intake gases to an internal combustion engine of a work vehicle, comprising:
providing a particulate media positioned to remove particulates from the intake gases;
providing a siloxane media positioned to remove siloxanes from the intake gases; and
sending an indication indicative of a remaining operational life of the siloxane media, the indication based on a pressure of the intake gases and a relationship between the pressure and the remaining operational life of the particulate media.
2. The method of claim 1 , wherein the particulate media has an expected operational life between 50% and 150% of the expected operational life of the siloxane media.
3. A work vehicle comprising:
ground-engaging tractive assemblies;
an internal combustion engine configured to power the ground-engaging tractive assemblies so as to move the work vehicle;
a filtration system positioned to filter intake gases to the engine, the filtration system comprising:
a housing;
a particulate media disposed within the housing, the particulate media configured to remove particulates from the intake gases; and
a siloxane media disposed within the housing, the siloxane media configured to remove siloxanes from the intake gases;
a pressure sensor configured to provide a pressure signal indicative of a pressure of the intake gases; and
a controller configured to receive the pressure signal and determine a remaining operational life of the siloxane media based on the pressure signal and a relationship between the pressure signal and the remaining operational life of the particulate media;
wherein:
the siloxane media is positioned in series with the particulate media relative to the flow of the intake gases;
the particulate media and the siloxane media each have a cylindrical shell shape;
one of the particulate media and the siloxane media is nested within the other of the particulate media and the siloxane media; and
an expected operational life of the particulate media is between 50% and 150% of an expected operational life of the siloxane media.
4. The work vehicle of claim 3 , further comprising an exhaust aftertreatment system positioned to treat exhaust from the engine.
5. The work vehicle of claim 3 , wherein the particulate media is positioned upstream of the siloxane media relative to the flow of the intake gases.
6. The work vehicle of claim 5 , wherein the particulate media has an expected operational life between 75% and 125% of the expected operational life of the siloxane media.
7. The work vehicle of claim 6 , wherein the expected operational life of the particulate media and the siloxane media is based on operation of the work vehicle in a landfill application.
8. The work vehicle of claim 3 , wherein the particulate media and the siloxane media are included in a filter media assembly, and the filter media assembly is configured so as to be installable within, and removable from, the housing as a single piece.
9. The work vehicle of claim 3 , wherein the siloxane media is positioned in series with the particulate media relative to the flow of the intake gases, the particulate media and the siloxane media are included in a filter media assembly, and the filter media assembly is configured so as to be installable within, and removable from, the housing as a single piece.
