Internal Combustion Engines by Rowland S.Benson

Internal Combustion Engines PDF

The ever-present energy crisis and the need for environmental controls have had a major impact on the development of the internal combustion engine. In this development a closer understanding of the thermodynamic processes occurring within the engine is necessary.

Both authors have been continuously involved in the industry and the universities over the past 30 years in the design, development, research and the teaching of internal combustion engines. The present text represents the fruits of some of their labors. Much of the material is original and some have not been published heretofore. The material has been used in the author's department in the final year's BSc courses and in the MSc course.

The text has been written as a companion to one of the authors (R.S, Benson's) text in the same series entitled Advanced Engineering Thermodynamics (2nd edition). A novel feature in the text is the presentation of FORTRAN listings of two programs for simple cycle calculations-one for a compression ignition engine cycle and the other for a spark-ignition engine cycle. Methods are also outlined for more complex cycle calculations of the type which are now normally carried ours in design offices. The quantitative material for combustion processes in compression ignition engines and some of the data for spark-ignition engines are based on the latest research carried out in the authors' laboratories.

The text is divided into two volumes to suit the convenience of students. The first volume contains material suitable for an undergraduate course in internal combustion engines, whilst the second volume is more relevant to postgraduate courses. 

The book is primarily concerned with the thermodynamics of internal combustion engines but inevitably we have included hardware features. Since the successful understanding of the processes in which the engine operates is dependent on experimental work, a section is included on experimental methods that are appended to Volume I although some of the techniques are only used in advanced research establishments.

The authors wish to acknowledge with thanks the help of the numerous research students, research assistants and technical staff in producing the data used in the text. They wish to thank the various publishers and institutions for the reproductions of figures, due acknowledgment of which is given in the appropriate place. 

They also wish to thank Mrs. M. McDonnell and Mrs. P. Shepherd for typing the draft and Mrs. J.A. Munro for typing the camera-ready copy of the text. 
they wish to thank their respective wives and families for their patience and forbearance for the many evenings and weekends spent in preparing the text.

The title Internal Combustion Engines may be somewhat misleading as it suggests too much. This work deals with internal, intermittent combustion engines, thus excluding the gas turbine, an internal continuous combustion engine. It excludes turbomachinery in general except for that important auxiliary the exhaust-driven turbocharger.

Another important limitation is that the intention is to deal with the thermodynamics and gas dynamics of engines-not the mechanical design. Some reference to the mechanical design is unavoidable because it impinges on the application of thermodynamics.


So some general descriptive matter is given in this chapter-but look elsewhere for detailed information on the structure and mechanics of engines. Internal, intermittent combustion engines are familiar to most people due to their ubiquity as the prime mover in motor vehicles. Usually, these engines are reciprocating engines in which a major moving part is a piston that moves in a straight line, backward and forwards, with an infinitesimal period at each extreme when it is stationary. Contrary to some popular opinion these reverses of the direction of motion do not affect efficiency-there are no losses inherently involved in this process. 

The advantages of rotary over reciprocating action are primarily a matter of compactness, of geometry, and do not directly involve thermodynamics and gas dynamics.  

The succeeding chapters may be applied to either rotary or reciprocating engines if the appropriate spatial characteristics are invoked-notably combustion chamber volumes, port areas, and surface areas and their changes with time. The genus of engines being considered may be subdivided into different categories in a number of ways. 

One way is in accordance with the use. Marine engines for the propulsion of ships at sea; industrial engines for power generation on land; automotive engines for land transport. source: Internal Combustion Engines by Rowland S.Benson PDF
