Steam Engine Indicators and Mechanics of the Steam Engine (Essential Steam Power Library)

74 pages. Reprint of the 1906 International Correspondence Schools ed. In part one you learn how the ingenious device called an indicator could draw on a card or piece of paper a diagram that showed the cylinder pressure at all points in the stroke. With it you could fix knocking, increase power output, and overcome poor efficiency. Part two covers the basic dynamics of engines: crank-effort diagrams, net forward pressure, inertia pressure from reciprocating parts, effect of the connecting rod on the inertia, crank-effort diagram of the Corliss engine, necessary weight of flywheel rim, prony brake, transmission dynamometer, and more.
