X.2565 With reference to Mr. Belnap's letter of May 11th. and Mr. Olley's letter of May 10th., the following is our report on the Items mentioned in Mr. Olley's memo:- Extract X.4305 - Lack of Heat in Induction Pipe. We agree that an improvement is necessary in the induction pipe. We hope in the course of two or three weeks we shall have completed our experiments, in the meantime we question whether the most is being made of the present design. We know that a number of cars went away which, owing to variation in the throttles, the carburation would be unsatisfactory. The effect of making those throttles correct will make a bigger difference to the car than we expect to make by the addition of heat. It should be emphasized that there is absolutely no reason why the carburation on the post-war cars should be any different to cars built from 1912. When I was in U.S.A. I appreciated that the pre-war cars there, were giving much more satisfaction with the carburation than the post-war cars. At that time the only variation I could think of that could make any difference was the change from aluminium pistons to cast iron pistons. Since then we have proved that there is a reason why the carburation of some post-war cars should be worse and we think that the first thing which should be tackled is to make the carburation on all post-war cars equal to pre-war cars, there is no reason why this cannot be done. | ||
