摘要: 随着海拔高度增加,三角转子发动机的功率会下降.为测试不同海拔高度下三角转子发动机性能,建立了三角转子发动机电控汽油喷射系统,并在发动机台架上通过模拟不同海拔高度下的进气压强,测试了不同进气压强下208 cm³排量电控汽油喷射三角转子发动机的性能,实现了发动机在空中运行时的实时监控和调节,进而提出了海拔补偿措施,为其在空中更好地运行提供了可能.

Abstract: With the increase of elevation,the power of the rotary engines is decreased in the higher air level.In order to measure the performances of rotary engine in different altitudes,an electronic fuel injection control system for the engine with real-time parameter monitor was put forward in the paper.Performance tests of a 208 cm³ engine were carried out by changing the atmospheric pressures to simulate the different elevations.An elevation compensation method was suggested for the engine's smooth running.The measured results provide very important references for control of these kinds of rotary engines to work stably in different heights in the sky.
