| 1133. To Jnr.{Charles L. Jenner} from Rm.{William Robotham - Chief Engineer} Rm.{William Robotham - Chief Engineer}13/MH.{M. Huckerby}7.3.40. Thank you for your note re the Hillman Minx and the Standard. These M.E.P. curves are very interesting. We are less surprised at the low maximum M.E.P. than we are at the power figure at 4,000 r.p.m. We expect that we shall have difficulty in getting anything above 110 M.E.P. on our 8 h.p. unit. The heat losses at low speed go up as the cylinder sizes come down. Rm.{William Robotham - Chief Engineer} | ||
