| RmB/R.{Sir Henry Royce} F.{Mr Friese} Kishline, Esq., The Graham-Paige Corporation, Detroit, Michigan, U.S.A. 24th MAY. 1937. Dear Kishline, I have written to Leylands with regard to your manufacturing some of their Diesel motors, under licence, but so far have not heard from them. We are still interested in supercharging by means of a centrifugal blower, and favour an arrangement in which the blower feeds down into the induction manifold, as it does in the Graham scheme. One of the drawbacks to this arrangement for English cars, especially with over-head valves, is the difficulty of obtaining sufficient head room for a downdraught carburetter and air silencer. We note that on the Lammas Graham, the problem has been solved by using an up-draught carburetter and leading the charge to the blower through a double bended jacketted pipe. We presume that this scheme was developed by yourselves, or at least that you have technical information regarding it, and we should be greatly obliged for any information you could give us comparing the behaviour of the standard system with the Lammas one. We have confirmed your experience that the cadmium nickel bearings stand up better than normal white metal, but should be interested to know whether you find that in this stage customers get hold of the wrong oils, and so get into trouble with corrosion. Yours sincerely, | ||
