Rolls-Royce Crecy Rolls-Royce Crecy The Rolls-Royce Crecy was an unusual British experimental two-stroke, 90-degree, V12, liquid-cooled aero-engine of 1,536 cu.in (26 L) capacity, featuring sleeve valves and direct petrol injection. Initially intended for a high-speed "sprint" interceptor fighter, the Crecy was later seen as an economical high-altitude long-range powerplant. Developed between 1941 and 1946, it was among the most advanced two-stroke aero-engine ever built. The engine never reached flight trials and the project was cancelled in December 1945, overtaken by the progress of jet engine development. The engine was named after the Battle of Crécy, after Rolls-Royce chose battles as the theme
