Abstract

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.

Claims (25)

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.
