Abstract
To improve the condition of air and eliminate exhaust gas pollution, this article proposes a compressed air power system. Instead of an internal combustion engine, the automobile is equipped with a compressed air engine, which transforms the energy of compressed air into mechanical motion energy. A prototype was built, and the compressed air engine was tested on an experimental platform. The output torque and energy efficiency were obtained from experimental results. When the supply pressure was set at 2 MPa and the speed was 420 r min−1, the output torque, the output power, and the energy efficiency were 56 N m, 1.93 kW, and 25%, respectively. To improve the efficiency of the system, a fuzzy logic speed control strategy is proposed and simulated. The experimental study verified that the theoretical evaluation of the system was reasonable, and this research can be referred to as the design and control of air-powered vehicles.

Summary
Especially by atmospheric fine particles, has been a severe problem for many years. The burning of fossil fuels through internal combustion engines in transportation vehicles has been a major source of this kind of air pollution.[1,2] According to relevant research reports, atmospheric fine particles (particulate matter 2.5 (PM2.5)) produced by automobiles are responsible for .30% of the air pollutants in Beijing.[3] The problem will continue to worsen as the number of automobiles increases. This environmental threat has made it imperative to develop a viable alternative to fossil fuels for transportation vehicles. This work presents an engine using compressed air as a possible solution.[4,5]
