A Study Of The Effect Of Aftercooling On The Power And The Weight Of A 2000 Horsepower Air Cooled Engine Installation

A study is made of the effect of aftercooling on the brake horsepower, the weight, and the weight-power ratio of a power plant consisting of a 2000-horsepower air-cooled engine, an intercooler, and two stages of supercharging. The study is for full-throttle operation at 30,000 feet. The dependence of brake horsepower on supercharger performance is stressed. Three cases are considered: (1) inadequate supercharging, (2) supercharging to constant manifold pressure, and (3) supercharging to detonation-limited manifold pressure.

This revised edition of Taylor's classic work on the internal-combustion engine incorporates changes and additions in engine design and control that have been brought on by the world petroleum crisis, the subsequent emphasis on fuel economy, and the legal restraints on air pollution. The fundamentals and the topical organization, however, remain the same. The analytic rather than merely descriptive treatment of actual engine cycles, the exhaustive studies of air capacity, heat flow, friction, and the effects of cylinder size, and the emphasis on application have been preserved. These are the basic qualities that have made Taylor's work indispensable to more than one generation of engineers and designers of internal-combustion engines, as well as to teachers and graduate students in the fields of power, internal-combustion engineering, and general machine design.
