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, an air assembly configured to supply air at a first pressure higher than atmospheric pressure to both the intake manifold and the tire inflation system, where the air assembly includes a first compressor stage and a second compressor stage.
Claims18
A vehicle having one or more pneumatic wheels, the vehicle comprising:
- 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;
- an air 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 air assembly includes a first compressor stage and a second compressor stage,
- wherein the air assembly is operable in a first mode, in which air output by the first compressor stage is directed to the intake manifold, a second mode, in which air output by the first and second compressor stages are directed to the intake manifold, and a third mode, in which air output by the first and second compressor stages are directed to the tire inflation system.
