| -3- run at full throttle without detonation. At a speed of 1,000 R.P.M. it gave an I.M.E.P. of 150.6 lbs/sq.in. and a B.M.E.P. of 113.1 lbs/sq.in. The engine was subsequently returned to Aspin. That is about all that we have to tell you and I am of course writing in a confidential way just for your personal information. In the four years that have passed since these early experiences one assumes that the invention has made progress in various ways but we have had no direct contact with Aspin's development work since the middle of 1940. I should be most interested to hear how you get on should you decide to make some tests on his latest designs. Kind regards. Yours sincerely, Maurice Platt MAURICE PLATT Power Unit Engineer | ||
