Abstract
An air cleaner assembly for an internal combustion engine and process for eliminating fuel emissions from passing into the atmosphere. The air cleaner assembly includes a housing including a filter element situated therein, an outlet for allowing filtered air to flow to the engine, and an inlet conduit extending from the housing for permitting the entry of air into the housing. A retainer is coupled to the inlet conduit. The retainer includes an adsorber member.
Claims17
An air cleaner assembly, comprising:
- a housing comprising an inlet conduit extending from the housing and an outlet;
- a retainer coupled to the inlet conduit, the retainer comprising a wall defining a first open end and a second open end, wherein the wall has a cuffed portion about the second open end forming a recess facing the first open end, wherein a portion of the inlet conduit is seated in the recess;
- and
- an adsorber member disposed within the first open end, wherein the adsorber member comprises an outer perimeter sealingly abutting against the retainer wall.
A process for reducing fuel emissions contained within an air cleaner assembly to an external atmosphere, the process comprising:
- securing a retainer to an inlet conduit of an air cleaner assembly, the retainer comprising a wall defining first and second open ends, wherein the wall has a cuffed portion about the second open end forming a recess facing the first open end, and wherein a portion of the inlet conduit is seated in the recess;
- sealingly engaging a hydrocarbon adsorber member in the first open end;
- securing a clamping device about the second open end of the retainer and the portion of the inlet conduit seated in the recess to form an air tight seal between the retainer and inlet conduit.
A process for operating an air cleaner assembly, the process comprising:
- operating an engine in fluid communication within the air cleaner assembly for drawing air from an external environment through the air cleaner assembly to the engine, wherein the air cleaner assembly comprises a housing containing a filter element, an inlet conduit extending from the housing and an outlet;
- a retainer coupled to the inlet conduit, the retainer comprising a wall defining a first open end and a second open end, wherein the wall has a cuffed portion about the second open end forming a recess facing the first open end, wherein a portion of the inlet conduit is seated in the recess;
- and an adsorber member disposed within the first open end, wherein the adsorber member comprises an outer perimeter sealingly abutting against the retainer wall;
- and
- treating a backflow of fluid from the engine to the air cleaner assembly with the adsorber member after shutdown of the engine to reduce fuel emissions into the external environment.
