Methods and systems are provided for using a forced induction system as a source of compressed air to pressurize a portable pressure vessel for inflating tires. In one example, a method may include providing instructions to the operator to initiate the method which includes the operator coupling the portable pressure vessel to a connection port included on the induction passage of the induction manifold. Responsive to more than one operator input, a controller selectively opens a pick-up valve in the connection port, and operates a plurality of engine systems to boost pressure in the induction passage to fill the portable pressure vessel.

Methods and systems are provided for operating an electric supercharger as an on-board air pump and/or vacuum pump. During conditions when a vehicle is not being propelled and the vehicle engine is idling, a portion of an air intake passage is sealed and the supercharger is operated to deliver compressed air into the sealed portion. Compressed air can then be picked up directly from the sealed portion for use in tire inflation, or picked up via an ejector to provide vacuum for vacuum actuators.

The invention relates to a distributed system (54) for supplying pressurized medium, in particular compressed air, in a vehicle (10), a wheel unit (14) for a vehicle (10), and a decentralized integrated pressurized medium supply device (70) for a wheel unit (14) with a rotatably supported vehicle tire (16). The pressurized medium supply device (70) has a decentralized compressor unit (74) and has a pressurized medium path (98) that extends between the decentralized compressor unit (74) and a rim body (92) of the vehicle tire (16), which rim body is associated with a wheel body side (80) of the wheel unit (14). The decentralized compressor unit (74) has an energy supply connection, which can be connected to an energy supply unit (104) via an energy supply path (106). The pressurized medium supply device (70) is associated with a support side (82) and the wheel body side (80) of the wheel unit (14). The pressurized medium path (98) or energy supply path (106) includes a rotary/stationary transition (116, 158) between the support side (82) and the wheel body side (80).

The air-compressing device for a cycle has a crank set. The device includes at least one cartridge for storing compressed air, and a compressor, connected to the cartridge. The compressor includes a device for engaging with the crank set and a first and a second compression chamber, each chamber provided with an air piston. The device for engaging is connected to each piston and translatably drives the stroke of each piston so as to carry out compression in the respective chamber. The first chamber is connected to the second chamber so as to transfer the compressed air within the first chamber to the second chamber when compression is being carried out in the latter.
