Abstract

An air induction system for delivering equal quantities of combustion air to an internal combustion engine has an air box assembly comprising a housing that defines a filter chamber that is configured to receive an air filter assembly, an air inlet that admits the fresh air into the housing and the filter chamber and outlets extending from the housing. The air filter assembly further comprises a filter media disposed between the air inlet and the outlets to define a filtered air chamber on a flow side of the filter media and a partition extending across the filtered air chamber to divide filtered, fresh air passing through the filter media into two flow paths, the divided flows paths exiting the housing and the filtered air chamber through the outlets.

Claims (33)

1. An internal combustion engine system comprising:

an air induction system comprising an intake runner receptive to a fresh air stream for delivery to an air box assembly containing an air filter assembly that operates to remove contaminants from the fresh air stream prior to delivery downstream and to other components of the internal combustion engine system including at least one turbocharger, the air box assembly comprising:

a housing that defines a filter chamber configured to receive the air filter assembly;

at least one air inlet that admits the fresh air stream from the intake runner into the housing and the filter chamber; and

outlets opening through the housing, the air filter assembly further comprising:

a filter media disposed between the air inlet and the outlets to define a filtered air chamber on a flow side of the filter media; and

a partition extending across the filtered air chamber through the air filter assembly to divide filtered, fresh air passing through the filter media into divided flow paths, the divided flow paths exiting the housing and the filtered air chamber through the outlets.

2. The internal combustion engine system of claim 1 , wherein the divided flow paths are receptive to substantially equal masses of filtered, fresh air.

3. The internal combustion engine system of claim 2 , further comprising Mass Air Flow (MAF) sensors located in the outlets and in fluid contact with the divided flow paths of filtered, fresh air to monitor airflow through the outlets.

4. The internal combustion engine system of claim 2 , wherein the at least one turbocharger includes a turbocharger disposed downstream of the outlets.

5. The internal combustion engine system of claim 1 , wherein the air filter assembly is constructed as one of a round or oval configuration to thereby define said filtered air chamber within a perimeter thereof.

6. The internal combustion engine system of claim 5 , wherein the air filter assembly includes the oval configuration and the filter media includes an oval shape that is received by and centrally located within the air filter assembly, the air filter assembly including a first end having a first oval perimeter, a second end having a second oval perimeter, first sealing member that extends about the first oval perimeter and a second sealing member that extends about the second oval perimeter.

7. The internal combustion engine system of claim 6 , wherein the air box assembly further comprises housing walls configured to press against corresponding ones of the first and second sealing members when the air filter assembly is disposed therebetween to define a seal between the filter media the at least one air inlet and the outlets, wherein fresh air entering the air box assembly is forced through the filter media prior to exiting the air box assembly through the outlets as filtered, fresh air.

8. The internal combustion engine system of claim 7 , wherein a housing wall is removable to allow for replacement of the air filter assembly.

9. The internal combustion engine system of claim 1 , wherein the at least one air inlet of the air box assembly comprises two air inlets that admit the fresh air stream into the housing and the filter chamber.

10. The internal combustion engine system of claim 9 , wherein the partition extends across the filter chamber, including the filtered air chamber defined by the filter media, to thereby divide the filter chamber into two chambers, defining a dual intake system.

11. The internal combustion engine system of claim 10 , wherein the partition comprises a two-part construction having a filter supported partition and a housing supported partition that align to provide a full partition that divides the filter chamber and separates the fresh air stream entering through the two air inlets.

12. An internal combustion engine system comprising:

an air induction system comprising an intake runner receptive to a fresh air stream for delivery to an air box assembly containing an air filter assembly that operates to remove contaminants from the fresh air stream prior to delivery downstream and to other components of the internal combustion engine system including at least one turbocharger, the air box assembly comprising:

a housing that defines a filter chamber configured to receive the air filter assembly;

an air inlet that admits fresh air from the intake runner into the housing and the filter chamber; and

outlets opening through the housing, the air filter assembly further comprising:

a filter media disposed between the air inlet and the outlets to define a filtered air chamber on a flow side of the filter media; and

a partition extending across the filtered air chamber through the air filter assembly to divide filtered, fresh air passing through the filter media into divided flow paths, the divided flow paths exiting the housing and the filtered air chamber through the outlets, wherein the partition is integral with the housing and extends outwardly from a wall thereof, providing a mounting location for the air filter assembly.

13. An air induction system for delivering equal quantities of combustion air to twin turbochargers of an internal combustion engine has an air box assembly comprising:

a housing that defines a filter chamber configured to receive an air filter assembly;

two air inlets that admit fresh air into the housing and the filter chamber; and

outlets opening through the housing, the air filter assembly further comprising:

a filter media disposed between the air inlet and the outlets to define a filtered air chamber on a flow side of the filter media; and

a partition extending across the filtered air chamber to divide filtered, fresh air passing through the filter media into two chambers defining a dual intake system having divided flow paths, the divided flow paths exiting the housing and the filtered air chamber through the outlets.

14. The air induction system of claim 13 , wherein the divided flow paths are receptive to substantially equal masses of filtered, fresh air.

15. The air induction system of claim 14 , further comprising Mass Air Flow (MAF) sensors located in the outlets and in fluid contact with the divided flow paths of filtered, fresh air to monitor airflow through the outlets.

16. The air induction system of claim 13 , wherein the partition comprises a two-part construction having a filter supported partition and a housing supported partition that align to provide a full partition that divides the filter chamber and separates incoming fresh air flows entering through the air inlets.
