Ignition Timing Impact on Elliptical Rotary Engines

Created using ChatSlide

This lecture examines an elliptical rotary engine, its design, operating conditions, and CFD-based research method. It explains model validation, airflow and combustion behavior under different rotary speeds and ignition timings, and the effects on flame development, pressure, and temperature. Key findings show that higher speeds intensify airflow and turbulence, while earlier ignition accelerates combustion. The lecture concludes with recommended ignition timings, including 25° BTDC as the...
