Basics of Internal Combustion Engines

Internal combustion engines power a vast portion of our world, yet understanding their internal mechanics, thermodynamic cycles, and timing processes can seem daunting. This text-based course breaks down these complex mechanical systems into clear, digestible concepts, starting with foundational terminology and core definitions. You will gain a solid working knowledge of how fuel-air mixtures transform into mechanical energy, comparing different engine layouts and analyzing their efficiency. Learn the precise sequence of operations that keep an engine running smoothly. What you will learn: Understand the core terminology, components, and structural differences of internal combustion engines; Compare the mechanical processes of two-stroke and four-stroke engines; Analyze thermodynamic cycles including Otto and Diesel cycles using pressure-volume diagrams; Read and interpret valve timing diagrams to understand gas exchange processes; Learn the principles of scavenging and modern fuel injection and emission reduction concepts. This course begins with the absolute basics of engine anatomy before guiding you through thermodynamic cycles, timing diagrams, and modern efficiency optimizations. It is designed specifically for beginners, engineering students, and automotive enthusiasts with no prior background in engine design.
