(The arrangement shown is, in general, that of a Woolf-tandcm compound engine.) between the incoming and issuing steam in each cylinder. But, because of the lower temperature range in each cylinder, the total condensation is considerably less in the compound engine than in either the single-or four-valve simple engine. It will therefore be evident from a study of the above explanation and of Figs. 327 to 329 that compounding reduces the temperature range in each compound-engine cylinder to approximately one-half of that of a simple engine in which the total temperature range is the same. Similar reasoning will disclose how the temperature range per cyliner may be further reduced by employing three or four cylinders as is done in triple-or quadruple-expansion engines. With a reduction in the temperature range per cylinder, the total cylinder condensation is reduced correspondingly. Note.--The Surfaces Of The Engine Cylinder With Which Steam, At Various Temperatures, Contacts assume, at different 275. Why Leakage Past The Piston And Valves Is Less In A Compound Engine Than In An Equivalent Simple Engine may be understood by referring to Figs. 328 and 329. The maximum difference between the pressures on the two sides of the piston and valves in the high-pressure cylinder (Fig. 329) is 150--25 = 125 lb. per sq. in.; and, in the low-pressure cylinder the difference is 25--1.7 =...
