Combustion Optimization in Elliptical Rotary Engines

Created using ChatSlide

This coursework examines how engine speed influences optimal ignition timing in an elliptical rotary engine (ERE). It introduces ERE and Wankel combustion characteristics, explains ignition timing and BTDC notation, and explores how speed affects airflow, turbulence, and burn duration. Using CFD simulations across 3,000, 5,000, and 7,000 r/min, the study develops understanding of combustion optimization and the relationship between rotational speed and ignition timing.
