| To R.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} c. to CJ. BJ. c. to RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} c. to BY.{R.W. Bailey - Chief Engineer} DA.{Bernard Day - Chassis Design} x766 Hsl/LGS.9.24. OVER-HEATING. x766 y3456 (y3456 is struck through) Our tests have proved that we get less heat to the water with [REDACTED] a high compression compared with a low compression engine. Our customers on the Continent claim that the high compression engines heat less water. Attached here-with is our explanation for this. Hs.{Lord Ernest Hives - Chair} | ||
