| 摘 要： | 应用有效能分析方法，对气动汽车动力系统主要环节的有效能消耗进行了分析，通过仿真计算，得到各环节的能耗值。分析结果表明：节流减压有效能损耗约占50％；吸热量很小的情况下，动力系统的输出的机械能只占总能量的20％左右，而按理想等温膨胀，输出的机械能可以达到总能量的40％。

| Abstract: | The energy consumption of air powered vehicle's energy system was analyzed.The research shows that about 50 percent of total energy is lost in throttling depressurization.When the expansion in cylinders is approximately adiabatic process,only 20 percent of total energy is transformed into mechanical energy as the engine's output,while 40 percent transformed when isothermal expansion. |
