Abstract


The paper presents the functional scheme of a pneumatic propulsion system for road vehicles. This includes a high-pressure air tank, a low-pressure air tank and a pneumatic motor that converts the energy stored in the compressed air tank into mechanical work. The design of the pneumatic motor is an innovative one (the authors have no information about such system that has been designed or manufactured worldwide). It takes over the functions of the gear box: the adjustment of the torque and the change of the rotational sense. In order to estimate
the autonomy of such a vehicle, one has developed an energy balance of the propulsion system. Based on the energy consumed for the generation of the high pressure compressed air it aims to estimate by calculus the distance that the vehicle can travel. This solution aims to offer a less polluting propulsion systems for the road vehicles. As known, the manufacturing and the recycling technologies for the electric batteries produce polluting materials and emissions.
