Simulation experiment of the influence of elevation on performance of a rotary engine

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.
