| Dr.J.C.Morrison. -2- 15th. June 1938. concluded that it is the later exhaust closing that is responsible for the improvement and that the same or a better result will be obtained by using the early timing but with increasing the duration of exhaust opening to give a late closing. We should like your opinion on this. Yours faithfully, for ROLLS-ROYCE LTD. | ||
