The invention discloses a power
system of a pneumatic automobile engine. The original
piston power
system of a pneumatic automobile has the defects of easy abrasion, high
noise and complicated interlinking mechanism. The power
system mainly comprises a high-pressure air
bottle (1) as a power source, a regulating valve (2) for realizing control, a heater (3) and a single-screw engine (4). By adopting a single-stage single-screw expansion engine or a multi-stage single-screw expansion engine as a pneumatic engine, the power system has the characteristics of simple structure,
low noise, long service life, simple control on the interlinking mechanism of the engine system and continuous and steady operation of an output shaft (5). The single-screw engine comprises a single-stage expansion mode and a multi-stage expansion mode, a multi-stage system connecting mode includes a serial
connection form, a parallel
connection form and a blend
connection form, and the power system has the advantages of flexible and diverse arrangement mode, wider application
working range of the engine and easy realization of connection and control. Due to the characteristics of the system, the invention has a great
advantage when applied to the pneumatic automobile engine.
