Content
By applying mathematical relationships between A.S.T.M. distillation and equilibrium air distillation curves of winter motor fuels it is shown (1) 1938 gasolines have pronounced lower vaporization temperatures than 1928 winter gasolines. (2) There still prevails so great a range in vaporization characteristics of winter fuels that a fixed relationship between vaporization temperature and supplied air-fuel ratios can make fuel induction systems inoperable. (3) Ideal supplied air-fuel ratios for current motor fuels range from 1:1 to 6:1 at a vaporization temperature of 10°F. and through corresponding ranges at higher and lower levels for other vaporization temperatures. (4) In general, the vaporization characteristics of modern winter gasolines are such that, except at extremely low vaporization temperatures, only a very moderate choking is necessary to attain operable air vapor mixtures.
