摘要：

In　order　to　overcome　the　disadvantage　of　the　existing　air-powered　engine,　a　new　compressed　air　power　system　based　on　single-screw　expander　is　proposed.　Some　analysis　is　discussed　in　theory　for　the　single-stage　system,　including　the　effects　of　expansion　ratio,　engine　efficiency　and　air　heat　temperature　to　the　total　output　and　the　evaluation　of　mean　endurance　mileage.　It　is　concluded　that　the　main　methods　to　improve　the　power　performance　of　the　single-stage　system　are　to　increase　the　expansion　ratio,　engine　efficiency　and　air　heat　temperature,　and,　the　running　duration　can　reach　over　90　km　totally　satisfying　the　need　of　short　distance　vehicle.
