• How Does a Wankel Rotary Engine Work?
  A Wankel rotary engine has a triangular rotor in an oval-like housing, and its three sealed pockets each complete intake, compression, power and exhaust in turn.
• How Jet Engines Work
  How jet engines turn fuel into thrust — the Brayton cycle, turbofan anatomy with compressors and turbines, bypass ratio, and what limits efficiency.
• The Four-Stroke Engine
  The internal combustion engine cycle of intake, compression, power, and exhaust strokes, governed by the Otto cycle.
• Second Law of Thermodynamics
  The law that entropy in an isolated system never decreases, fixing the direction of natural processes and limiting the efficiency of engines.
