The Effect of Valve Timing Upon the Performance of a Supercharged Engine at Altitude and an Unsupercharged Engine at Sea Level
This is a 1932 NACA technical report by NASA Technical Reports Server records, not a general book, examining how intake valve timing affects supercharged and unsupercharged aircraft engines at altitude and sea level. The graphs plot brake horsepower, fuel consumption, friction and compression pressure against valve timing in crank degrees, while the other plates show indicator diagrams and a laboratory engine test rig, useful to a designer wanting technical charts or engineering laboratory imagery.
