Internal Combustion Engines: Theory, Calculation and Practice

The book Internal Combustion Engines: Theory, Calculation and Practice provides a comprehensive overview of the principles, operation, and applications of internal combustion engines. It begins by introducing the fundamental laws of thermodynamics and their application to thermal machines, emphasizing cycles such as Carnot, Otto, and Diesel, which establish the theoretical basis for efficiency and performance. A detailed classification of internal combustion engines follows, including spark ignition engines, compression ignition engines, two-stroke and four-stroke cycles, as well as rotary designs such as the Wankel engine.

The text also examines the structural constitution of engines, distinguishing between fixed parts—such as the block, cylinder head, and crankcase—and moving parts, including the piston, connecting rod, crankshaft, camshaft, and valves. In addition, auxiliary systems like cooling, lubrication, fuel supply, and distribution are presented as essential components for ensuring durability and efficiency.

A significant section of the book is dedicated to engine calculation, addressing parameters such as displacement, compression ratio, torque, piston speed, and mechanical efficiency. Practical tools and methods for repair, torque specifications, and fastening elements are also described, providing both theoretical and applied perspectives.

Furthermore, the volume includes extensive guidance on maintenance and diagnosis, emphasizing auditory and visual inspections, compression and vacuum tests, oil pressure evaluation, and calibration procedures. The final chapters focus on repair practices, covering disassembly, cleaning, adjustment, and reassembly of critical engine components and systems.

This work is designed as both an academic resource and a practical manual, offering students, technicians, and professionals a solid foundation for understanding, analyzing, and repairing internal combustion engines.
