Abstract

A vehicle having one or more inflatable wheels, the vehicle including an internal combustion engine including a cylinder, a tire inflation system in fluid communication with and configured to selectively direct compressed air into at least one wheel of the one or more inflatable wheels, a compressor assembly having an outlet, where the compressor assembly is operable in a first mode, in which the outlet is in fluid communication with the cylinder of the internal combustion engine, and a second mode, in which the outlet is in fluid communication with the tire inflation system.

First claim

The invention claimed is:

1. A vehicle having one or more inflatable wheels, the vehicle comprising:
an internal combustion engine including a cylinder and an exhaust manifold in fluid communication with the cylinder;
a tire inflation system in fluid communication with and configured to selectively direct compressed air into at least one wheel of the one or more inflatable wheels;
a compressor assembly having a first outlet, wherein the compressor assembly includes an electric motor, and wherein the electric motor rotates a compressor wheel relative to a compressor housing independent of the operation of the internal combustion engine,
a turbocharger driven by the exhaust manifold and having a second outlet configured to output a compressed airflow;
wherein the vehicle is operable in a first mode, in which the first outlet is in fluid communication with the cylinder of the internal combustion engine, and a second mode, in which the first outlet is in fluid communication with the tire inflation system and the second outlet is in fluid communication with and discharging the compressed airflow into the cylinder of the internal combustion engine.

2. The vehicle of claim 1 , wherein the compressor assembly includes a compressor housing including the first outlet, and a compressor wheel positioned at least partially within and rotatable with respect to the compressor housing, and wherein the compressor wheel is rotatable relative to the compressor housing.

3. The vehicle of claim 1 , wherein the compressor assembly includes an inlet, and wherein the vehicle includes a bypass extending between the compressor inlet and the first outlet of the compressor assembly, and wherein the bypass is adjustable between an open configuration, in which air can flow through the bypass, and a closed configuration, in which air cannot flow through the bypass.

4. The vehicle of claim 1 , wherein the first outlet is in fluid communication with both the tire inflation system and the cylinder in the first mode.

5. The vehicle of claim 1 , wherein the first outlet is not in fluid communication with the cylinder in the second mode.

6. The vehicle of claim 1 , further comprising a first valve having a first opening in fluid communication with the first outlet of the compressor assembly and a second opening in fluid communication with the cylinder, and wherein the first valve is adjustable between an open position, in which the first opening is in fluid communication with the second opening, and a closed position, in which the first opening is not in fluid communication with the second opening.

7. The vehicle of claim 6 , wherein the compressor assembly includes an inlet, the vehicle further comprising a second valve having a first opening in fluid communication with the inlet and a second opening in fluid communication with the first outlet, and wherein the second valve is adjustable between an open position, in which the first opening is in fluid communication with the second opening, and a closed position, in which the first opening is not in fluid communication with the second opening.

8. The vehicle of claim 7 , wherein the first valve is in the open configuration and the second valve is in the closed configuration during the first mode.

9. The vehicle of claim 1 , further comprising a manifold including
a first passageway configured to be open to and in fluid communication with the cylinder of the internal combustion engine,
a second passageway configured to be open to and in fluid communication with the tire inflation system,
a first valve having a first opening in constant fluid communication with an inlet of the compressor assembly, and a second opening in constant fluid communication with the first passageway, wherein the first valve is adjustable between an open configuration, in which the first opening is in fluid communication with the second opening, and a closed configuration, in which the first opening is not in fluid communication with the second opening,
a second valve having a third opening in constant fluid communication with the first outlet of the compressor assembly, and a fourth opening in constant fluid communication with the first passageway, wherein the second valve is adjustable between an open configuration, in which the third opening is in fluid communication with the fourth opening, and a closed configuration, in which the third opening is not in fluid communication with the fourth opening, and
wherein the second passageway is in fluid communication with the first outlet of the compressor assembly.

10. The vehicle of claim 9 , wherein the the first valve is in the open configuration and the second valve is in the open configuration when the vehicle is operating in the first mode, wherein the first valve is in the closed configuration and the second valve is in the open configuration when the vehicle is operating in a third mode, and wherein the first valve is in the open configuration and the second valve is in the closed configuration when the vehicle is operating in the second mode.

11. The vehicle of claim 10 , wherein the compressor wheel is driven relative to the compressor housing when the vehicle is in the second mode and the third mode.

12. The vehicle of claim 10 , wherein the compressor wheel is not driven relative to the compressor housing when the vehicle is in the first mode.

13. The vehicle of claim 9 , wherein the manifold includes a third passageway configured to be placed in fluid communication with the second outlet of the turbocharger, and wherein the third passageway is in fluid communication with the inlet of the compressor assembly.

14. The vehicle of claim 13 , wherein the third passageway is in fluid communication with the first opening of the first valve.

15. The vehicle of claim 13 , wherein the third passageway is in fluid communication with the first outlet of the compressor assembly.

16. A vehicle having one or more inflatable wheels, the vehicle comprising:
an internal combustion engine including a cylinder;
a tire inflation system in fluid communication with and configured to selectively direct compressed air into at least one wheel of the one or more inflatable wheels;
a compressor assembly having a first outlet, wherein the compressor assembly includes an electric motor, and wherein the electric motor rotates the compressor wheel relative to the compressor housing independent of the operation of the internal combustion engine,
a turbocharger driven by the exhaust manifold and having a second outlet;
wherein the vehicle is operable in a first mode, in which the first outlet is in fluid communication with the cylinder of the internal combustion engine, and a second mode, in which the first outlet is in fluid communication with the tire inflation system and not in fluid communication with the cylinder of the combustion engine, and the second outlet is in fluid communication with the cylinder of the internal combustion engine.
