IC Engine Performance: Testing and Combustion Fundamentals

Understanding how internal combustion engines generate power and burn fuel is essential for any aspiring automotive or mechanical engineer. This text-based course guides you through the foundational thermodynamics, testing methodologies, and chemical processes that drive engine design. By reading through our structured explanations and working through practical calculation exercises, you will develop a clear, intuitive grasp of how to evaluate engine efficiency and diagnose combustion issues. What you'll learn: - Understand the fundamental terminology, cycles, and operating principles of SI and CI engines. - Calculate engine performance metrics including Brake Power, Indicated Power, and Friction Power. - Analyze engine efficiency using classic evaluation methods like the Morse Test and Motoring Test. - Examine the stages of combustion, flame propagation, and abnormal combustion in spark-ignition and compression-ignition systems. - Explore modern emission standards and the basics of electronic engine diagnostics. The course begins with core definitions and mechanical principles before moving into mathematical formulations for engine testing. You will then explore detailed written breakdowns of the combustion phases and modern diagnostic concepts. This course is designed for beginners, engineering students, and automotive enthusiasts with no prior experience in engine testing.
