Abstract

This research aims to reveal the comprehensive influence of rotary speed and intake closing timing (ICT) on turbulent kinetic energy (TKE), volumetric efficiency, combustion characteristics of the elliptical rotary engine (ERE). Therefore, computational fluid dynamics (CFD) model that can accurately describe the working process of the ERE was established and validated through experimental data. Simulation results show that, with the advance of ICT and the rotary speed increases, the TKE increases, the volumetric efficiency increases. With the advance of ICT and the effective compression ratio increases, the combustion speed increases, the combustion reaction is more intense, the flame development period and the rapid combustion period is shorten. As the rotary speed increases, the combustion phase increases. With the advance of ICT, the average pressure and temperature increases, indicated thermal efficiency decreases, the indicated power increases. As the rotary speed increases, the average pressure and temperature decrease, the indicated thermal efficiency and indicated power increases. This research proposes a means of matching the rotary speed and ICT of the ERE.
