| TO HS.{Lord Ernest Hives - Chair}) FROM R.{Sir Henry Royce} C. to - BJ. WOR.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} ORIGINAL TR{Capt. F. W. Turner - Finance} 20 AUG 1926 VALVE EROSION - CURTISS RECEIVED R3/M19.8.26. X3366 XL605 We were rather surprised to find this just as bad on the Curtiss engine, which strongly suggests that it is not entirely due to arc of lifter, as this engine has direct lifters giving a straight line. We have an advantage over the Curtiss because we have rollers to work on our cams. We suggest you set someone to find how to always get valve erosion, such as loose valve guides, letting steam or water into the cylinders, after which we could find how to stop or avoid it.
