Book Description
Internal Combustion of Engines: A Detailed Introduction to the Thermodynamics of Spark and Compression Ignition Engines, Their Design and Development focuses on the design, development, and operations of spark and compression ignition engines. The book first describes internal combustion engines, including rotary, compression, and indirect or spark ignition engines. The publication then discusses basic thermodynamics and gas dynamics. Topics include first and second laws of thermodynamics; internal energy and enthalpy diagrams; gas mixtures and homocentric flow; and state equation. The text takes a look at air standard cycle and combustion in spark and compression ignition engines. Air standard cycle efficiencies; models for compression ignition combustion calculations; chemical thermodynamic models for normal combustion; and combustion-generated emissions are underscored. The publication also considers heat transfer in engines, including heat transfer in internal combustion and instantaneous heat transfer calculations. The book is a dependable reference for readers interested in spark and compression ignition engines.

Book Description
The knock-limited performance of nine fuels, comprising isolated members of four classes of hydrocarbons, paraffins, cycloparaffins, and olefins), is presented in the form of three-dimensional plots of fuel-air ratio, compression temperature, and compression-air density. The plots are based on a correlation that is shown to apply for these fuels over a wide range of compression that is shown to apply for these fuels over a wide range of compression ratios and inlet-air temperatures. The significance of the term "temperature sensitivity" is sketched, and it is emphasized that no generalized number such as octane number can be applied even to members of a given class of hydrocarbons when broad ranges of engine severity are encountered.

Book Description
Concern about the reduced availability and the increased cost of petroleum fuels prompted great efforts in recent years to reduce the fuel consumption of auto mobiles. The ongoing efforts to reduce fuel consumption have addressed many relevant factors, including increased engine performance, reduced friction, use of lightweight materials, and reduced aerodynamic drag. The results of the investigations assessing the various factors affecting fuel economy have been published in journals, conference proceedings, and in company and government reports. This proliferation of technical information makes it difficult for workers to keep abreast of aU developments. The material presented in this book brings together in a single volume much of the relevant materials, summarizes many of the state-of-the-art theories and data, and provides extensive lists of references. Thus, it is hoped that this book will be a useful reference for specialists and practicing engineers interested in the fuel economy of automobiles. J. C. HILLIARD o. S. SPRINGER vii CONTENTS 1.

Book Description
The results are given of an investigation of some of the limitations that now prevent increases in the temperature level of engine cylinder heads, and a review of previous work in the field is included to supplement these results. Attention was given, in particular, to the effects of fuel knock and surface ignition on cylinder temperatures and the effects of cylinder temperatures on performance. Data were obtained from a Wright C9GC air-cooled cylinder and from a Lycoming O-1230 liquid-cooled cylinder.
