Design and Experimental Research of Pneumatic Micro-rotary Engine

The design of millimeter-scale rotary engine(Wankel) was introduced,which is quite different from large-scale engine's parts design and manufacture.To avoid the affection of micro-combustion due to reducing engine's scale,high-pressure gas was used to drive engine.A micro-rotary internal combustion engine was developed,in which the high energy density hydrocarbon was used as fuels.The pneumatic micro-rotary engine test bench was presented.The experimental result shows that the engine speed and power output increases when increasing inlet gas pressure,and the engine's output power and efficiency will increase obviously as engine's seal is improved.
