This modern textbook on internal combustion engines covers methods of analysis, issues in engine design and experimental methods. The author draws on all the student has learned in thermodynamics, fluid mechanics, heat transfer and numerical methods to illustrate methods of analysis in a complex real world situation. The text is unusual in its presentation of cycle analysis with computer calculated thermodynamic properties instead of tables and charts. The book also includes a variety of challenging homework problems. Although most of the material is presented in SI units, units such as calorie, rpm and bar are also used.
