Modeling and Simulation of Two-Stage Expansion Air-Powered Engine

Abstract:

Thermodynamic simulation of a two-stage expansion air-powered engine was established and working process simulation was conducted based on this model. The effects of inlet pressure (0.8Mpa-3.0Mpa), intake duration angle of second-stage (100°CA-160°CA) and cylinder diameter of second-stage (120mm-200mm) on the gas temperature, pressure and output torque were analyzed. The results show that effective power and output torque both increase with the increase of above three parameters, meanwhile effective gas consumption rate decreases.
