Optimizing Elliptical Rotary Engine Ignition Timing

Created using ChatSlide

This coursework examines how ignition timing and rotary speed influence combustion in an XMv3 eccentric rotary engine. It reviews engine advantages, modeling methods, CFD validation, airflow and turbulence behavior, and combustion performance across five ignition timings and three speeds. The analysis shows that advanced ignition accelerates combustion, while engine speed affects pressure, temperature, airflow, and turbulent kinetic energy. Based on the findings, recommended timings are 20°,...
