| Aries X108. To E.{Mr Elliott - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}6/KT.30.5.33. The attached curve was taken when we were playing about with the Peregrine induction system trying to improve the distribution. The interesting point is the type of hot spot temperature required for best carburation and the limitations of the existing type of exhaust heated hot spot. Though we have been able to get away with the water heated hot spot due to the wide mixture range provided, there is no doubt that the exhaust heated hot spot is far superior from the point of view of rapid warming up, its only disadvantage being that if enough heat is provided at low speeds, too much is given to the mixture at high speeds when running all out. We think that some method of exhaust heated control providing nearly ideal conditions is worthy of design consideration. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
