From the Rolls-Royce experimental archive: a quarter of a million communications from Rolls-Royce, 1906 to 1960's. Documents from the Sir Henry Royce Memorial Foundation (SHRMF).
Engine performance improvements through increased MEP and compression ratio, noting limitations from detonation and proposing solutions.

TO HS.{Lord Ernest Hives - Chair} } FROM R.{Sir Henry Royce} C.C. to P.I. " WCH. " B.T. ORIGINAL R2/M9.11.26. BETTER MEP. AT ALL SPEEDS UP TO 3000 RPM. & 4 1/2 COMPRESSION RATIO. X684 X8771 X8005 This cannot be increased because of detonations and reaction vibrations. However, corrected auto ignition - (i.e. excessive and suitably timed advance - auto) can be made to eliminate moderate detonations, and minimise torque reactions. R.{Sir Henry Royce} | ||
