| Abstract: | In order to improve the capacity of the piston doing work,dynamics performance and economic performance of a pneumatic engine,an inlet and exhaust system of piston-exhausting air-powered engine is modeled,and the model of pneumatic engine thermodynamic cycle was established based on thermodynamic theory of variable mass.By simulating the influence of the different inlet and exhaust opening angle,duration angle and speed on various properties of the engine,it is concluded that:(1) proper opening angle is con... |
