Pneumatic Power Unit for a Wheeled Vehicle

The article theoretically substantiates the choice of the full-load curve of a pneumatic power unit and a pneumatic power unit combined with an internal combustion engine by the example of a compact wheeled vehicle. The aim is to prove the possibility of using a pneumatic power unit for moving the compact wheeled vehicle taking into account work processes of a pneumatic power unit and an internal combustion engine. The unique feature of the considered theoretical approach in justifying the choice of the full-load curve of a pneumatic power unit and a pneumatic power unit combined with an internal combustion engine is comparison of operating modes of units being a part of a vehicle and the using the capacity of different units combination with similar burn processes at 800-1000 RPM^-1. The suggested principle of combining power units with different work processes allows to determine the feasibility of sharing a pneumatic power unit and an internal combustion engine in heavy traffic on busy road sections in cities and megalopolises. The review part of the paper provides the analysis of scientific publications about the possibility of using a pneumatic power unit as an alternative unit by means of which the wheeled vehicle can be moved. The performed analysis of the combined full-load curve of a pneumatic power unit with an internal combustion engine shows the possibility of using compressed air as an alternative source to ensure the moving a compact wheeled vehicle in the urban cycle under the conditions of a busy road with heavy traffic.
