ROTARY ENGINE PERFORMANCE IMPROVED THROUGH NEW INDUCTION SYSTEM

In a rotary engine, effects of an overlap magnitude between intake and exhaust port timing on ignitability at light load and effects of intake closing timing chiefly on volumetric efficiency at the w.o.t. were investigated. With these results, a new induction system called the 2-rotor 6-port induction system that greatly improves fuel economy at light load while maintaining high performance over all engine speeds, has been developed.
