Abstract
A vehicle having one or more pneumatic wheels, the vehicle including an internal combustion engine including a cylinder and an intake manifold in fluid communication with the cylinder, a tire inflation system configured to direct air into at least one of the one or more inflatable wheels, and a compressor assembly configured to supply air at a first pressure higher than atmospheric pressure to both the intake manifold and the tire inflation system.
Claims14
A vehicle having one or more pneumatic wheels, the vehicle comprising:
- an internal combustion engine including a cylinder, an intake manifold in fluid communication with the cylinder, and an exhaust manifold in communication with the cylinder;
- a tire inflation system configured to direct air into at least one of the one or more inflatable wheels;
- a compressor assembly configured to supply air at a first pressure higher than atmospheric pressure to both the intake manifold and the tire inflation system, 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;
- and
- a turbocharger driven by the exhaust manifold, wherein the turbocharger is configured to supply air at a pressure higher than atmospheric pressure to the intake manifold of the internal combustion engine at least when the compressor assembly is supplying air to the tire inflation system.

A vehicle having one or more pneumatic wheels, the vehicle comprising:
- an internal combustion engine including a cylinder, an intake manifold in fluid communication with the cylinder, and an exhaust manifold in communication with the cylinder;
- a tire inflation system configured to direct air into at least one of the one or more pneumatic wheels;
- a compressor assembly having a first output, wherein the compressor assembly is configured to output a first compressed airflow to the intake manifold and the tire inflation system, 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;
- and
- a turbocharger driven by the exhaust manifold and positioned upstream of the compressor assembly, wherein the turbocharger outputs a second compressed airflow, and wherein the second compressed airflow is able to bypass the compressor assembly when being directed into the intake manifold.
